Twenty five years after the launch of CVE, the Tenable Security Response Team has handpicked 25 vulnerabilities that stand out for their significance.

Background

In January 1999, David E. Mann and Steven M. Christey published the paper “Towards a Common Enumeration of Vulnerabilities” describing an effort to create interoperability between multiple vulnerability databases. To achieve a common taxonomy for vulnerabilities and exposures, they proposed Common Vulnerabilities and Exposures (CVE). In September 1999, the MITRE Corporation finalized the first CVE list, which included 321 records. CVE was revealed to the world the following month.

As of October 2024, there are over 240,000 CVEs. including many that have significantly impacted consumers, businesses and governments. The Tenable Security Response Team has chosen to highlight the following 25 significant vulnerabilities, followed by links to product coverage for Tenable customers to utilize.

As organizations create and store more data in the cloud, security teams must ensure the data is protected from cyberthreats. Learn more about what causes data breaches and about the best practices you can adopt to secure data stored in the cloud.

With the explosion of data being generated and stored in the cloud, hackers are creating new and innovative attack techniques to gain access to cloud environments and steal data. A review of recent major data breaches shows us that data thieves are using social engineering, hunting for exposed credentials, looking for unpatched vulnerabilities and misconfigurations and employing other sophisticated techniques to breach cloud environments.

A look at recent cloud data-breach trends

Here are some takeaways from major data breaches that have occurred this year:

• Managing the risk from your third-parties – partners, service providers, vendors – has always been critical. It’s even more so when these trusted organizations have access to your cloud environment and cloud data. You must make sure that your third-parties are using proper cloud-security protections to safeguard their access to your cloud data and to your cloud environment.
• Secure your identities. We’ve seen major data breaches this year tracked down to simple missteps like failing to protect highly-privileged admin accounts and services with multi-factor authentication (MFA). 
• Adopt best practices to prevent ransomware attacks, and to mitigate them if you get hit by one. Ransomware gangs know that a surefire way to pressure victims into paying ransoms is to hijack their systems and threaten to expose their sensitive data. 

So, how can you strengthen your data security posture against these types of attacks?

1. Implement a "zero trust" security framework that requires all users, whether inside or outside the organization, to be authenticated, authorized and continuously validated before being granted or maintaining access to data. This framework should allow only time-limited access and be based on the principle of least privilege, which limits access and usage to the minimum amount of data required to perform the job.
2. Use a cloud data security posture management (DSPM) solution to enforce the security framework through continuous monitoring, automation, prioritization and visibility. DSPM solutions can help organizations identify and prioritize data security risks based on their severity, allowing them to focus their resources on the most critical issues.
3. Regularly conduct risk assessments to detect and remediate security risks before they can be exploited by hackers. This can help prevent data breaches and minimize the impact of any security incidents that do occur.
4. Train employees on security best practices, including how to create strong passwords, how to identify risks and how to report suspicious activity.

By following these recommendations, organizations can significantly reduce their risk of a data breach and improve handling sensitive data belonging to their organization. As more and more data moves to the cloud and hackers become more sophisticated, it's essential to prioritize security and take proactive measures to protect against data risks.

Looking for help with shadow AI? Want to boost your software updates’ safety? New publications offer valuable tips. Plus, learn why GenAI and data security have become top drivers of cyber strategies. And get the latest on the top “no-nos” for software security; the EU’s new cyber law; and CISOs’ communications with boards.

Dive into six things that are top of mind for the week ending Oct. 25.

1 - CSA: How to prevent “shadow AI” 

As organizations scale up their AI adoption, they must closely track their AI assets to secure them and mitigate their cyber risk. This includes monitoring the usage of unapproved AI tools by employees — an issue known as “shadow AI.”

So how do you identify, manage and prevent shadow AI? You may find useful ideas in the Cloud Security Alliance’s new “AI Organizational Responsibilities: Governance, Risk Management, Compliance and Cultural Aspects” white paper.

The white paper covers shadow AI topics including:

• Creating a comprehensive inventory of AI systems
• Conducting gap analyses to spot discrepancies between approved and actual AI usage
• Implementing ways to detect unauthorized AI wares
• Establishing effective access controls
• Deploying monitoring techniques

“By focusing on these key areas, organizations can significantly reduce the risks associated with shadow AI, ensuring that all AI systems align with organizational policies, security standards, and regulatory requirements,” the white paper reads.

For example, to create an inventory that offers the required visibility into AI assets, the document explains different elements each record should have, such as:

• The asset’s description
• Information about its AI models
• Information about its data sets and data sources
• Information about the tools used for its development and deployment
• Detailed documentation about its lifecycle, regulatory compliance, ethical considerations and adherence to industry standards
• Records of its access control mechanisms

Shadow AI is one of four topics covered in the publication, which also unpacks risk management; governance and compliance; and safety culture and training.

To get more details, read:

• The full “AI Organizational Responsibilities: Governance, Risk Management, Compliance and Cultural Aspects” white paper
• A complementary slide presentation
• The CSA blog “Shadow AI Prevention: Safeguarding Your Organization’s AI Landscape”

2 - Best practices for secure software updates

The security and reliability of software updates took center stage in July when an errant update caused massive and unprecedented tech outages globally.

To help prevent such episodes, U.S. and Australian cyber agencies have published “Safe Software Deployment: How Software Manufacturers Can Ensure Reliability for Customers.”

“It is critical for all software manufacturers to implement a safe software deployment program supported by verified processes, including robust testing and measurements,” reads the 12-page document.

Although the guide is aimed primarily at commercial software vendors, its recommendations can be useful for any organization with software development teams that deploy updates internally.

The guide outlines key steps for a secure software development process, including planning; development and testing; internal rollout; and controlled rollout. It also addresses errors and emergency protocols.

“A safe software deployment process should be integrated with the organization’s SDLC, quality program, risk tolerance, and understanding of the customer’s environment and operations,” reads the guide, authored by the U.S. Cybersecurity and Infrastructure Security Agency (CISA), the FBI and the Australian Cyber Security Centre.

To get more details, read:

3 - Report: GenAI, attack variety, data security drive cyber strategies

What issues act as catalysts for organizations’ cybersecurity actions today? Hint: They’re fairly recent concerns. The promise and peril of generative AI ranks first. It’s closely followed by the ever growing variety of cyberattacks; and by the intensifying urgency to protect data.

That’s according to CompTIA’s “State of Cybersecurity 2025” report, based on a survey of almost 1,200 business and IT pros in North America and in parts of Europe and Asia. 

These three key factors, along with others like the scale of attacks, play a critical role in how organizations currently outline their cybersecurity game plans.

“Understanding these drivers is essential for organizations to develop proactive and adaptive cybersecurity strategies that address the evolving threat landscape and safeguard their digital assets,” reads a CompTIA blog about the report.

Organizations are eagerly trying to understand both how generative AI can help their cybersecurity programs and how this technology is being used by malicious actors to make cyberattacks harder to detect and prevent.

Meanwhile, concern about data protection has ballooned in the past couple of years. “As organizations become more data-driven, the need to protect sensitive information has never been more crucial,” reads the blog.

Not only are organizations focused on securing data at rest, in transit and in use, but they’re also creating foundational data-management practices, according to the report.

“The rise of AI has accelerated the need for robust data practices in order to properly train AI algorithms, and the demand for data science continues to be strong as businesses seek competitive differentiation,” the report reads.

To get more details, read:

• The report’s announcement “Cybersecurity success hinges on full organizational support, new CompTIA report asserts”
• CompTIA’s blogs “Today’s top drivers for cybersecurity strategy” and “Cybersecurity’s maturity: CompTIA’s State of Cybersecurity 2025 report”

4 - CISA lists software dev practices most harmful for security

Recommended best practices abound in the cybersecurity world. However, CISA and the FBI are taking the opposite tack in their quest to improve the security of software products: They just released a list of the worst security practices that software manufacturers ought to avoid.

Titled “Product Security Bad Practices,” the document groups the “no-nos” into three main categories: product properties; security features; and organizational processes and policies.

“It’s 2024, and basic, preventable software defects continue to enable crippling attacks against hospitals, schools, and other critical infrastructure. This has to stop,” CISA Director Jen Easterly said in a statement.

“These product security bad practices pose unacceptable risks in this day and age, and yet are all too common,” she added.

Here are some of the worst practices detailed in the document, which is part of CISA’s “Secure by Design” effort:

• Using programming languages considered “memory unsafe”
• Including user-provided input in SQL query strings
• Releasing a product with default passwords
• Releasing a product with known and exploited vulnerabilities
• Not using multi-factor authentication
• Failing to disclose vulnerabilities in a timely manner

Although the guidance is aimed primarily at software makers whose products are used by critical infrastructure organizations, the recommendations apply to all software manufacturers.

If you’re interested in sharing your feedback with CISA and the FBI, you can submit comments about the document until December 16, 2024 on the Federal Register.

To get more details, check out:

• CISA’s announcement “CISA and FBI Release Product Security Bad Practices for Public Comment”
• The full document “Product Security Bad Practices”

5 - New EU law focuses on cybersecurity of connected digital products

Makers of digital products — both software and hardware — that directly or indirectly connect to networks and to other devices will have to comply with specific cybersecurity safeguards in the European Union.

A newly adopted law known as the “Cyber Resilience Act” outlines cybersecurity requirements for the design, development, production and lifecycle maintenance of these types of products, including IoT wares such as connected cars.

For example, it specifies a number of “essential cybersecurity requirements” for these products, including that they:

• Aren’t shipped with known exploitable vulnerabilities
• Feature a “secure by default” configuration
• Can fix their vulnerabilities via automatic software updates
• Offer access protection via control mechanisms, such as authentication and identity management
• Protect the data they store, transmit and process using, for example, at-rest and in-transit encryption

“The new regulation aims to fill the gaps, clarify the links, and make the existing cybersecurity legislative framework more coherent, ensuring that products with digital components (...) are made secure throughout the supply chain and throughout their lifecycle,” reads a statement from the EU’s European Council.

The law will “enter into force” after its publication in the EU’s official journal and will apply and be enforceable 36 months later, so most likely in October 2027 or November 2027. However, some of its provisions will be enforceable a year prior.

6 - UK cyber agency: CISOs must communicate better with boards

CISOs and boards of directors are struggling to understand each other, and this is increasing their organizations’ cyber risk, new research from the U.K.’s cyber agency has found.

For example, in one alarming finding, 80% of respondents, which included board members, CISOs and other cyber leaders in medium and large enterprises, confessed to being unsure of who is ultimately accountable for cybersecurity in their organizations.

“We found that in many organisations, the CISO (or equivalent role) thought that the Board was accountable, whilst the Board thought it was the CISO,” reads a blog about the research titled “How to talk to board members about cyber.”

As a result, the U.K. National Cyber Security Centre (NCSC) has released new guidance aimed at helping CISOs better communicate with their organizations’ boards titled “Engaging with Boards to improve the management of cyber security risk.”

“Cyber security is a strategic issue, which means you must engage with Boards on their terms and in their language to ensure the cyber risk is understood, managed and mitigated,” the document reads.

Here’s a small sampling of the advice:

• Understand your audience, including who are the board’s members and their areas of expertise; and how the board works, such as its meeting formats and its committees.
• Talk about cybersecurity in terms of risks, and outline these risks concretely and precisely, presenting them in a matter-of-fact way.
• Don’t limit your communication with board members to formal board meetings. Look for opportunities to talk to them individually or in small groups outside of these board meetings.
• Elevate the discussions so that you link cybersecurity with your organization’s business challenges, goals and context.
• Aim to provide a holistic view, and avoid using technical jargon.
• Aim to advise instead of to educate.

The CISA Known Exploited Vulnerabilities (KEV) catalog and enhanced logging guidelines are among the new measurement tools added for the 2024 State and Local Cybersecurity Grant Program.

Last month, the Department of Homeland Security announced the availability of $279.9 million in grant funding for the Fiscal Year (FY) 2024 State and Local Cybersecurity Grant Program (SLCGP). Now in its third year, the four-year, $1 billion program provides funding for State, Local and Territorial (SLT) governments to implement cybersecurity solutions that address the growing threats and risks to their information systems. Applications must be submitted by December 3, 2024.

While there are no significant modifications to the program for FY 2024, the Federal Emergency Management Agency (FEMA), which administers SLCGP in coordination with the Cybersecurity and Infrastructure Security Agency (CISA), identified key changes, some of which we highlight below:

The FY 2024 NOFO adds CISA’s KEV catalog as a new performance measure and recommended resource

The FY 2024 notice of funding opportunity (NOFO) adds the CISA Known Exploited Vulnerabilities (KEV) catalog as a recommended resource to encourage governments to regularly view information related to cybersecurity vulnerabilities confirmed by CISA, prioritizing those exploited in the wild. In addition, CISA has added “Addressing CISA-identified cybersecurity vulnerabilities” to the list of performance measures it will collect through the duration of the program.

Tenable offers fastest, broadest coverage of CISA’s KEV catalog

At Tenable, our goal is to help organizations identify their cyber exposure gaps as accurately and quickly as possible. To achieve this goal, we have research teams around the globe working to provide precise and prompt coverage for new threats as they are discovered. Tenable monitors and tracks additions to the CISA KEV catalog on a daily basis and prioritizes developing new detections where they do not already exist.

Tenable updates the KEV coverage of its vulnerability management products — Tenable Nessus, Tenable Security Center and Tenable Vulnerability Management — allowing organizations to use KEV catalog data as an additional prioritization metric when figuring out what to fix first. The ready availability of this data in Tenable products can help agencies meet the SLCGP performance measures. This blog offers additional information on Tenable’s coverage of CISA’s KEV catalog.

FY 2024 NOFO adds “Adopting Enhanced Logging” as a new performance measure

The FY 2024 NOFO also adds “Adopting Enhanced Logging” to the list of performance measures CISA will collect throughout the program duration.

How Tenable’s library of compliance audits can help with Enhanced Logging

Tenable's library of Compliance Audits, including Center for Internet Security (CIS) and Defense Information Systems Agency (DISA), allows organizations to assess systems for compliance, including ensuring Enhanced Logging is enabled. Tenable's vulnerability management tools enable customers to easily schedule compliance scans. Users can choose from a continuously updated library of built-in audits or upload custom audits. By conducting these scans regularly, organizations can ensure their systems are secure and maintain compliance with required frameworks.

FY 2024 NOFO continues to require applicants to address program objectives in their applications

As with previous years, the FY 2024 NOFO sets four program objectives. Applicants must address at least one of the following in their applications:

• Objective 1: Develop and establish appropriate governance structures, including by developing, implementing, or revising Cybersecurity Plans, to improve capabilities to respond to cybersecurity incidents, and ensure operations.
• Objective 2: Understand their current cybersecurity posture and areas for improvement based on continuous testing, evaluation, and structured assessments.
• Objective 3: Implement security protections commensurate with risk.
• Objective 4: Ensure organization personnel are appropriately trained in cybersecurity, commensurate with responsibility.

How Tenable can help agencies meet Objective 2 of the program

Tenable is uniquely positioned to help SLTs meet Objective 2 through the Tenable One Exposure Management Platform. In addition to analyzing traditional IT environments, Tenable One analyzes cloud instances, web applications, critical infrastructure environments, identity access and privilege solutions such as Active Directory and more — including highly dynamic assets like mobile devices, virtual machines and containers. Once the complete attack surface is understood, the Tenable One platform applies a proactive risk-based approach to managing exposure, allowing SLT agencies to successfully meet each of the sub-objectives outlined in Objective 2 (see table below).

Tenable One deployment options offer flexibility for SLT agencies

Tenable offers SLT agencies flexibility in their implementation models to help them best meet the requirements and objectives outlined as part of the SLCGP. Deployment models include:

• Centralized risk-based vulnerability program managed by a state Department of Information Technology (DoIT)
• Multi-entity projects
• Decentralized deployments of Tenable One managed by individual municipalities,
• Managed Security Service Provider (MSSP) models that allow agencies to rapidly adopt solutions by utilizing Tenable’s Technology Partner network.

Whole-of-state approach enables state-wide collaboration and cooperation

A “whole-of-state” approach — which enables state-wide collaboration to improve the cybersecurity posture of all stakeholders — allows state governments to share resources to support cybersecurity programs for local government entities, educational institutions and other organizations. Shared resources increase the level of defense for SLTs both individually and as a community and reduce duplication of work and effort. States get real-time visibility into all threats and deploy a standard strategy and toolset to improve cyber hygiene, accelerate incident response and reduce statewide risk. For more information, read Protecting Local Government Agencies with a Whole-of-State Cybersecurity Approach.

FY 2024 NOFO advises SLT agencies to adopt key cybersecurity best practices

As in previous years, the FY 2024 NOFO again recommends SLT agencies adopt key cybersecurity best practices. To do this, they are required to consult the CISA Cross-Sector Cybersecurity Performance Goals (CPGs) throughout their development of plans and projects within the program. This is also a statutory requirement for receiving grant funding.

How Tenable One can help agencies meet the CISA CPGs

The CISA CPGs are a prioritized subset of cybersecurity practices aimed at meaningfully reducing risk to critical infrastructure operations and the American people. They provide a common set of IT and operational technology (OT) fundamental cybersecurity best practices to help SLT agencies address some of the most common and impactful cyber risks.

Should critical infrastructure orgs boost OT/ICS systems’ security with zero trust? Absolutely, the CSA says. Meanwhile, the Five Eyes countries offer cyber advice to tech startups. Plus, a survey finds “shadow AI” weakening data governance. And get the latest on MFA methods, CISO trends and Uncle Sam’s AI strategy.

Dive into six things that are top of mind for the week ending Nov. 1.

1 - Securing OT/ICS in critical infrastructure with zero trust

As their operational technology (OT) computing environments become more digitized, converged with IT systems and cloud-based, critical infrastructure organizations should beef up their cybersecurity by adopting zero trust principles.

That’s the key message of the Cloud Security Alliance’s “Zero Trust Guidance for Critical Infrastructure,” which focuses on applying zero trust methods to OT and industrial control system (ICS) systems.

While OT/ICS environments were historically air gapped, that’s rarely the case anymore. “Modern systems are often interconnected via embedded wireless access, cloud and other internet-connected services, and software-as-a-service (SaaS) applications,” reads the 64-page white paper, which was published this week.

The CSA hopes the document will help cybersecurity teams and OT/ICS operators enhance the way they communicate and collaborate.

Among the topics covered are:

• Critical infrastructure’s unique threat vectors
• The convergence of IT/OT with digital transformation
• Architecture and technology differences between OT and IT

The guide also outlines this five-step process for implementing zero trust in OT/ICS environments:

• Define the surface to be protected
• Map operational flows
• Build a zero trust architecture
• Draft a zero trust policy
• Monitor and maintain the environment

A zero trust strategy boosts the security of critical OT/ICS systems by helping teams “keep pace with rapid technological advancements and the evolving threat landscape,” Jennifer Minella, the paper’s lead author, said in a statement.

2 - Five Eyes publish cyber guidance for tech startups

Startup tech companies can be attractive targets for hackers, especially if they have weak cybersecurity and valuable intellectual property (IP).

To help startups prevent cyberattacks, the Five Eyes countries this week published cybersecurity guides tailored for these companies and their investors.

“This guidance is designed to help tech startups protect their innovation, reputation, and growth, while also helping tech investors fortify their portfolio companies against security risks," Mike Casey, U.S. National Counterintelligence and Security Center Director, said in a statement.

These are the top five cybersecurity recommendations from Australia, Canada, New Zealand, the U.S. and the U.K. for tech startups:

• Be aware of threat vectors, including malicious insiders, insecure IT and supply chain risk.
• Identify your most critical assets and conduct a risk assessment to pinpoint vulnerabilities.
• Build security into your products by managing intellectual assets and IP; monitoring who has access to sensitive information; and ensuring this information’s protection.
• Conduct due diligence when choosing partners and make sure they’re equipped to protect the data you share with them.
• Before you expand abroad, prepare and become informed about these new markets by, for example, understanding local laws in areas such as IP protection and data protection.

“Sophisticated nation-state adversaries, like China, are working hard to steal the intellectual property held by some of our countries’ most innovative and exciting startups,” Ken McCallum, Director General of the U.K.’s MI5, said in a statement.

3 - Survey: Unapproved AI use impacting data governance

Employees’ use of unauthorized AI tools is creating compliance issues in a majority of organizations. Specifically, it makes it harder to control data governance and compliance, according to almost 60% of organizations surveyed by market researcher Vanson Bourne.

“Amid all the investment and adoption enthusiasm, many organisations are struggling for control and visibility over its use,” reads the firm’s “AI Barometer: October 2024” publication. Vanson Bourne polls 100 IT and business executives each month about their AI investment plans.

To what extent do you think the unsanctioned use of AI tools is impacting your organisation's ability to maintain control over data governance and compliance?

^{(Source: Vanson Bourne’s “AI Barometer: October 2024”)}

Close to half of organizations surveyed (44%) believe that at least 10% of their employees are using unapproved AI tools.

On a related front, organizations are also grappling with the issue of software vendors that unilaterally and silently add AI features to their products, especially to their SaaS applications.

While surveyed organizations say they’re reaping advantages from their AI usage, “such benefits are dependent on IT teams having the tools to address the control and visibility challenges they face,” the publication reads.

For more information about the use of unapproved AI tools, an issue also known as “shadow AI,” check out:

4 - NCSC explains nuances of multi-factor authentication

Multi-factor authentication (MFA) comes in a variety of flavors, and understanding the differences is critical for choosing the right option for each use case in your organization.

To help cybersecurity teams better understand the different MFA types and their pluses and minuses, the U.K. National Cyber Security Centre (NCSC) has updated its MFA guidance.

“The new guidance explains the benefits that come with strong authentication, while also minimising the friction that some users associate with MFA,” reads an NCSC blog.

In other words, what type of MFA method to use depends on people’s roles, how they work, the devices they use, the applications or services they’re accessing and so on.

Topics covered include:

• Recommended types of MFA, such as FIDO2 credentials, app-based and hardware-based code generators and message-based methods
• The importance of using strong MFA to secure users’ access to sensitive data
• The role of trusted devices in boosting and simplifying MFA
• Bad practices that weaken MFA’s effectiveness, such as:
  • Retaining weaker, password-only authentication protocols for legacy services
  • Excluding certain accounts from MFA requirements because their users, usually high-ranking officials, find MFA inconvenient

To get more details, read:

• The NCSC blog “Not all types of MFA are created equal”
• The NCSC guide “Multi-factor authentication for your corporate online services”

5 - U.S. gov’t outlines AI strategy, ties it to national security 

The White House has laid out its expectations for how the federal government ought to promote the development of AI in order to safeguard U.S. national security.

In the country’s first-ever National Security Memorandum (NSM) on AI, the Biden administration said the federal government must accomplish the following:

• Ensure the U.S. is the leader in the development of safe, secure and trustworthy AI
• Leverage advanced AI technologies to boost national security
• Advance global AI consensus and governance

“The NSM’s fundamental premise is that advances at the frontier of AI will have significant implications for national security and foreign policy in the near future,” reads a White House statement.

The NSM’s directives to federal agencies include:

• Help improve the security of chips and support the development of powerful supercomputers to be used by AI systems.
• Help AI developers protect their work against foreign spies by providing them with cybersecurity and counterintelligence information.
• Collaborate with international partners to create a governance framework for using AI in a way that is ethical, responsible and respects human rights. 

The White House also published a complementary document titled “Framework To Advance AI Governance and Risk Management in National Security,” which adds implementation details and guidance for the NSM.

6 - State CISOs on the frontlines of AI security

As the cybersecurity risks and benefits of AI multiply, most U.S. state CISOs find themselves at the center of their governments' efforts to craft AI security strategies and policies.

That’s according to the “2024 Deloitte-NASCIO Cybersecurity Study,” which surveyed CISOs from all 50 states and the District of Columbia.

Specifically, 88% of state CISOs reported being involved in the development of a generative AI strategy, while 96% are involved with creating a generative AI security policy.

However, their involvement in AI cybersecurity matters isn’t necessarily making them optimistic about their states’ ability to fend off AI-boosted attacks.

None said they feel “extremely confident” that their state can prevent AI-boosted attacks, while only 10% reported feeling “very confident.” The majority (43%) said they feel “somewhat confident” while the rest said they are either “not very confident” or “not confident at all.”

Naturally, most state CISOs see AI-enabled cyberthreats as significant, with 71% categorizing them as either “very high threat” (18%) or “somewhat high threat” (53%).

At the same time, state CISOs see the potential for AI to help their cybersecurity efforts, as 41% are already using generative AI for cybersecurity, and another 43% have plans to do so by mid-2025.

Other findings from the "2024 Deloitte-NASCIO Cybersecurity Study" include:

• 4 in 10 state CISOs feel their budget is insufficient.
• Almost half of respondents rank cybersecurity staffing as one of the top challenges.
• In the past two years, 23 states have hired new CISOs, as the median tenure of a state CISO has dropped to 23 months, down from 30 months in 2022.
• More state CISOs are taking on privacy protection duties — 86% are responsible for privacy protection, up from 60% two years ago.

Preventing data loss, complying with regulations, automating workflows and managing access are four key challenges facing financial institutions. Learn how Tenable can help.

Imagine a bustling bank, made not of bricks and mortar, but of a swirling mass of data in the cloud. Account numbers, transaction histories and personally identifiable information (PII) zip across servers, powering the financial world. Holding all this sensitive data requires tremendous care. Therefore, securing this sensitive information is paramount.

This is where Tenable Cloud Security steps in, offering a data security shield specifically designed for the unique needs of financial institutions.

The challenge: A data deluge demands vigilance

Financial institutions generate massive volumes of data daily. While the public cloud offers unparalleled capacity to store such data, along with agility and scalability, the cloud also expands the attack surface. Legacy cybersecurity solutions are often unable to manage — let alone secure — the sheer volume of data and the variety of ways it is accessed, leaving organizations exposed to malicious actors. At the same time, financial institutions must keep up with new and evolving compliance standards and regulations set forth by governing bodies. Financial institutions need a security platform that helps them protect their data and maintain compliance.

Tenable Cloud Security’s advantage: Seeing beyond the walls

Tenable Cloud Security actively scrutinizes every corner of the cloud data vault, continuously and automatically.

"Without [Tenable Cloud Security], we would've been virtually blind to risks and threats impacting our sensitive data. [Tenable Cloud Security] allows us to preempt any issues and meet the requirements we're receiving from our business partners, with minimal effort.

— VP Security at a leading Fintech platform

Here's how Tenable empowers financial institutions:

• Protecting sensitive data: Tenable doesn't just guard the door; it knows what's inside and how to best protect it. It identifies and labels all data, like financial records and social security numbers, understanding its sensitivity and prioritizing its protection.
• Continuous monitoring: Imagine guards constantly scanning every inch of the vault. Tenable does the same digitally, using advanced technology to constantly search for suspicious activity and potential breaches. Any unusual movement of the data, either exfiltration or copying to a different and inaccessible location, triggers an alarm, allowing for immediate intervention.
• Policy enforcement: Just like a vault needs clear access protocols, so does your data. Tenable automates setting and enforcing cybersecurity policies across the entire cloud, ensuring everyone plays by the book and no unauthorized hands touch the valuables.
• Following mandated regulations: Financial institutions juggle a complex set of regulations and industry standards like the Payment Card Industry Data Security Standard (PCI-DSS). Tenable simplifies compliance with a host of international regulations by providing timely reports and audit trails.

Beyond traditional security: More than just a lock

Modern technology stacks for data storage require a modern cybersecurity stack. Traditional security solutions are unable to address the unique risks associated with storing data in cloud technologies. Financial organizations that leverage Tenable’s data security platform are able to meet existing and future challenges, including:

• Preventing data loss: Early detection and prevention of unauthorized data access can help organizations minimize financial losses and reputational damage, keeping valuable assets safe from even the most cunning thieves.
• Complying with regulations: Automated reports and adherence to the most stringent regulations and industry standards ensure compliance, saving time and resources.
• Automating workflows: Tenable automates tasks and provides deeper insights into how data behaves, enabling organizations to free up their valuable resources for other endeavors and make their security teams more efficient.
• Managing access: Just like knowing who has access to the vault is crucial. Tenable tracks who and what has access to data, ensuring only authorized parties can handle the data.

The future of financial security is data-centric

Tenable Cloud Security's data-centric approach positions it as a valuable partner, not just for guarding the perimeter but for understanding the inner workings of the vault and the most sensitive data within it. By leveraging Tenable’s capabilities, financial institutions can confidently embrace the cloud while ensuring the highest level of security for their most valuable assets — their data.

Vulnerability management remains a cornerstone of preventive cybersecurity, but organizations still struggle with vulnerability overload and sophisticated threats. Tenable’s new Exposure Signals gives security teams comprehensive context, so they can shift from vulnerability management to exposure management and effectively prioritize high-risk exposures across their complex attack surface.

A critical vulnerability has been disclosed and attackers worldwide are actively exploiting it in the wild. Your vulnerability management team jumps into action and determines that the vulnerability is present in hundreds of your organization’s assets. Which ones do you patch first? How do you prioritize your remediation efforts? What criteria do you use? The clock is ticking. Hackers are on the prowl.

Historically, your vulnerability management team would rely on severity scores like Vulnerability Priority Rating (VPR). This is a great start, but only gives you one indicator of risk. To prioritize remediation precisely and effectively, you need to consider a variety of other criteria, such as a vulnerable asset’s type, owner, and function; the access-level and privileges on the asset; and critical attack paths into your environment.

This type of comprehensive, holistic context will let you prioritize correctly, but it can only be achieved with a different approach that goes beyond traditional vulnerability management. That approach is exposure management. 

With exposure management, your vulnerability management team would be able to pinpoint the subset of assets affected by our hypothetical vulnerability that, for example, are externally accessible, possess domain-level privileges and are part of a critical attack path. That way they would know where the greatest risk is and what they need to remediate first. Having this deep insight, context and visibility transforms the risk assessment equation, and allows your vulnerability management team to move decisively, quickly and strategically.

In this blog, we’ll outline why it’s imperative for your vulnerability management teams to shift to an exposure management mindset, and we’ll explain how Tenable can help them do it.

To pinpoint riskiest vulns, vulnerability management needs broader exposure context 

In today's evolving cybersecurity landscape, vulnerability management remains one of the foundational pieces of an organization's proactive defense strategy. However, these teams still have difficulty in addressing the increased level of risks posed by the continuous surge of Common Vulnerabilities and Exposures (CVEs) and other flaws.

Many security teams are frequently overwhelmed by the sheer volume of vulnerabilities with limited resources to manage them effectively. The sophistication and speed of threat actors has escalated, with attackers having more entry points and using new tactics, techniques and procedures to access other critical areas of the business - demonstrating that attacks are no longer linear but multifaceted.

It’s common for security teams to struggle with:

• Vulnerability overload - This long-standing problem keeps getting worse. Security teams are finding it more difficult than ever to sift through the avalanche of CVEs and identify the areas of the business that have the most risk.
   
•  Lack of exposure context for prioritization - Your teams are making decisions while missing layers of context. Threat intelligence and vulnerability severity are a great start, but limiting yourself to them doesn’t give you the full context you need to prioritize properly. 
   
• Slow remediation response - Both proactive and reactive security teams devote massive amounts of time to responding to critical vulnerabilities. Resources are spread thin, making it more important than ever for teams to confidently identify the most high risk exposures when recommending remediation efforts.

Need to shift from a vulnerability to an exposure mindset

Knowing the struggles that you are dealing with today can help illuminate the benefits of exposure management. The missing links between a vulnerability and an exposure are the additional layers of context. Having multidimensional context enables you to understand not just the vulnerabilities themselves but their potential impact within the broader attack surface. This approach provides a more comprehensive view of an organization's security posture by considering factors such as threat intelligence, asset criticality, identities and access, as well as other pieces of context. With this additional information, you spend significantly less time sorting through stacks of similar vulnerabilities and you can be more focused on identifying key issues that pose risk - exposures.

For those who have never heard of exposure management or are just getting started, there are many benefits to this discipline. When it comes to Tenable’s approach, we adopt that same mentality with our exposure management platform. The goal is simple: exposure management empowers organizations to prioritize remediation efforts more effectively. It surfaces information that helps develop strategies to address not only the vulnerabilities themselves but the emergence of exposures that could lead to significant breaches.

The jump from vulnerability to exposure

Bridging the gap from vulnerability management to exposure management requires connecting context across the entire attack surface. Vulnerability management provides context that predicts the likelihood of an attack and displays key drivers, age of vulnerability and threat sources. These attributes are helpful, but we can go much further to improve our prioritization effectiveness. This requires having broader visibility and deeper insights across the attack surface to understand the bigger picture of exposures.

Specifically, security teams need additional context around:

• Asset context - There are many levels to an asset that can help drive prioritization decisions. It’s key to understand the criticality of an asset related to its type, function, owner name and its relationships to other assets. Even knowing if the asset is accessible from the internet or not will shape how its remediation is prioritized.
   
• Identities - Identities serve as the cornerstone for successful attacks, so it’s key to contextualize them for exposure management. Understanding user-privilege levels, entitlements and user information can help prevent attackers from gaining privilege escalation and moving laterally. Focusing prioritization efforts on vulnerable assets with domain and admin-level privileges is a critical best practice in order to reduce the likelihood of a breach.
   
• Threat context - Having various levels of threat context is also important to prioritize exposures. We know that threats change over time, so leveraging dynamic scoring like VPR or Asset Exposure Score (AES) can show indicators of risk. We can also bring in context from attack path modeling to influence remediation decisions based on the attacker’s perspective by understanding the number of critical attack paths or choke points in your environment.

When security analysts have this additional information, they can now truly understand the breadth and depth of the exposure. This is how prioritization is done in this new world of exposure management.

Introducing Exposure Signals

To help make it easier for you to shift to this exposure management mindset, we have developed a new prioritization capability called Exposure Signals. Available in Tenable One, Tenable’s exposure management platform, Exposure Signals allows security teams to have more comprehensive context in a centralized place for a focused view of risk. 

There are two ways to use these new Exposure Signals. The first is to access a comprehensive library of high-risk, prebuilt signals. Easy to refer to, they signal potential risk in your environment and create a great starting point for you to get your exposure management juices flowing. For example, you can easily see and refer to: 

• Domain admin group on internet-exposed hosts with critical vulnerabilities
• Devices exposed to the internet via RDP with an associated identity account with a compromised password
• Cloud assets with critical severity findings and asset exposure score above 700

Exposure Signals allow you to track the number of violations that signal high-risk scenarios in your environment. View this list on a regular basis to see how it changes over time with its unique trendline. Take exploration into your own hands by viewing the impacted asset and its contextual intelligence in our Inventory Module. 

The second way to use Exposure Signals is by creating your own signals using a query builder or natural language processing (NLP) search powered by ExposureAI. That way, you can go as broad or as precise as needed. For example, let’s say there is a new zero day vulnerability that sweeps the industry, similar to Log4Shell. You can easily create a signal to target which assets have the vulnerability, are internet facing and have domain admin-level privileges. We are stringing these components together so that you can understand your true risk and better direct your prioritization efforts.

CISA is warning about a spear-phishing campaign that spreads malicious RDP files. Plus, OWASP is offering guidance about deepfakes and AI security. Meanwhile, cybercriminals have amplified their use of malware for fake software-update attacks. And get the latest on CISA’s international plan, Interpol’s cyber crackdown and ransomware trends.

Dive into six things that are top of mind for the week ending Nov. 8.

1 - CISA: Beware of nasty spear-phishing campaign

Proactively restrict outbound remote-desktop protocol (RDP) connections. Block transmission of RDP files via email. Prevent RDP file execution.

Those are three security measures cyber teams should proactively take in response to an ongoing and “large scale” email spear-phishing campaign targeting victims with malicious RDP files, according to the U.S. Cybersecurity and Infrastructure Security Agency (CISA).

A foreign threat actor is carrying out the campaign. Several vertical sectors, including government and IT, are being targeted.

“Once access has been gained, the threat actor may pursue additional activity, such as deploying malicious code to achieve persistent access to the target’s network,” CISA’s alert reads.
 

Other CISA recommendations include:

• Adopt phishing-resistant multi-factor authentication (MFA), such as FIDO tokens, and try to avoid SMS-based MFA
• Educate users on how to spot suspicious emails
• Hunt for malicious activity in your network looking for indicators of compromise (IoCs) and tactics, techniques and procedures

Although CISA didn’t name the hacker group responsible for this campaign, its alert includes links to related articles from Microsoft and AWS that identify it as Midnight Blizzard. Also known as APT29, this group is affiliated with Russia’s government.

To get more details, check out the CISA alert “Foreign Threat Actor Conducting Large-Scale Spear-Phishing Campaign with RDP Attachments.”

2 - OWASP issues AI security resources

How should your organization respond to deepfakes? What’s the right way of establishing a center of excellence for AI security in your organization? Where can you find a comprehensive guide of tools to secure generative AI applications?

These questions are addressed in a new set of resources for AI security from the Open Worldwide Application Security Project’s OWASP Top 10 for LLM Application Security Project. 

The new resources are meant to help organizations securely adopt, develop and deploy LLM and generative AI systems and applications “with a comprehensive strategy encompassing governance, collaboration and practical tools,” OWASP said in a statement.

These are the new resources:

• “The Guide for Preparing and Responding to Deepfake Events,” which unpacks four types of deepfake schemes – financial fraud, job interview fraud, social engineering and misinformation – and offers guidance about each one in these areas:
  • preparation
  • detection and analysis
  • containment eradication and recovery
  • post-incident activity
• “The LLM and GenAI Center of Excellence Guide,” which aims to help CISOs and fellow organization leaders create a center of excellence for generative AI security that facilitates collaboration among various teams, including security, legal, data science and operations, so they can develop:
  • Generative AI security policies
  • Risk assessment and management processes
  • Training and awareness
  • Research and development
• “The AI Security Solution Landscape Guide,” which offers security teams a comprehensive catalog of open source and commercial tools for securing LLMs and generative AI applications.

3 - Fake update variants dominate list of top malware in Q3

Hackers are doubling down on fake software-update attacks.

That’s the main takeaway from the Center for Internet Security’s list of the 10 most prevalent malware used during the third quarter.

Malware variants used to carry out fake browser-update attacks took the top four spots on the list: SocGholish, LandUpdate808, ClearFake and ZPHP. Collectively, they accounted for 77% of the quarter’s malware infections. It's the first time LandUpdate808 and ClearFake appear on this quarterly list.

^{(Source: “Top 10 Malware Q3 2024”, Center for Internet Security, October 2024)}

In a fake software-update attack, a victim gets duped into installing a legitimate-looking update for, say, their preferred browser, that instead infects their computers with malware.

Here’s the full list, in descending order:

• SocGholish, a downloader distributed through malicious websites that tricks users into downloading it by offering fake software updates 
• LandUpdate808, a JavaScript downloader distributed through malicious websites via fake browser updates
• ClearFake, another JavaScript downloader used for fake browser-update attacks
• ZPHP, another JavaScript downloader used for fake software-update attacks
• Agent Tesla, a remote access trojan (RAT) that captures credentials, keystrokes and screenshots
• CoinMiner, a cryptocurrency miner that spreads using Windows Management Instrumentation (WMI)
• Arechclient2, also known as SectopRAT, is a .NET RAT whose capabilities include multiple stealth functions
• Mirai, a malware botnet that compromises IoT devices to launch DDoS attacks
• NanoCore, a RAT that spreads via malspam as a malicious Excel spreadsheet
• Lumma Stealer, an infostealer used to swipe personally identifiable information (PII), credentials, cookies and banking information

4 - CISA’s first international plan unveiled

CISA has released its first-ever international plan, which outlines a strategy for boosting the agency’s collaboration with cybersecurity agencies from other countries.

Aligning cybersecurity efforts and goals with international partners is critical for tackling cyberthreats in the U.S. and abroad, according to the agency.

The three core pillars of CISA’s “2025 - 2026 International Strategic Plan” are:

• Help make more resilient other countries’ assets, systems and networks that impact U.S. critical infrastructure

5 - Interpol hits phishers, ransomware gangs, info stealers

Interpol and its partners took down 22,000 malicious IP addresses and seized thousands of servers, laptops, and mobile phones used by cybercriminals to conduct phishing scams, deploy ransomware and steal information.

The four-month global operation, titled Synergia II and announced this week, involved law enforcement agencies and private-sector partners from 95 countries and netted 41 arrests.

“Together, we’ve not only dismantled malicious infrastructure but also prevented hundreds of thousands of potential victims from falling prey to cybercrime,” Neal Jetton, Director of Interpol’s Cybercrime Directorate, said in a statement.

In Hong Kong, more than 1,000 servers were taken offline, while authorities in Macau, China took another 291 servers offline. Meanwhile, in Estonia, authorities seized 80GB of server data, which is now being analyzed for links to phishing and banking malware.

6 - IST: Ransomware attacks surged in 2023

Ransomware gangs went into hyperdrive last year, increasing their attacks by 73% compared with 2022, according to the non-profit think tank Institute for Security and Technology (IST).

The IST attributes the sharp increase in attacks to a shift by ransomware groups to “big game hunting” – going after prominent, large organizations with deep pockets. 

“Available evidence suggests that government and industry actions taken in 2023 were not enough to significantly reduce the profitability of the ransomware model,” reads an IST blog.

Global Ransomware Incidents in 2023

Another takeaway: The ransomware-as-a-service (RaaS) model continued to prove extremely profitable in 2023, and it injected dynamism into the ransomware ecosystem. 

The RaaS model prompted ransomware groups “to shift allegiances, form new groups, or iterate existing variants,” the IST blog reads.

The industry sector that ransomware groups hit the hardest was construction, followed by hospitals and healthcare, and by IT services and consulting. Financial services and law offices rounded out the top five.
