ETSI publishes a white paper introducing Permissioned Distributed Ledger (PDL)

Sophia Antipolis, 24 January 2022

After the release of the first specification on smart contracts on 18 January, members from the ETSI PDL group published a White Paper entitled “An Introduction of Permissioned Distributed Ledger (PDL)”.

Distributed ledgers have consolidated as one of the most disruptive applications of information technology that have appeared in recent years. Their ability to store any kind of data as a consensus of replicated, shared, and synchronized digital records distributed across multiple sites, without depending on any central administrator, together with their properties regarding immutability (and therefore non-repudiation) and multi-party verifiability opens a wide range of applications.

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.

• 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”
• The full “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”

• “Guidelines for Software Development (Australian Cyber Security Centre)

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.

"Snap's town had a witch. At least, that's how the rumor goes. But in reality, Jacks is just a crocks-wearing, internet-savvy old lady who sells roadkill skeletons online— after doing a little ritual to put their spirits to rest. It's creepy, sure, but Snap thinks it's kind of cool, too. They make a deal: Jacks will teach Snap how to take care of the baby opossums that Snap rescued, and Snap will help Jacks with her work. But as Snap starts to get to know Jacks, she realizes that Jacks may in fact have real magic— and a connection with Snap's family's past." -- Provided by publisher.

This past weekend, Spider-Man: Across the Spider-Verse had the second largest domestic opening of 2023, netting (or should we say webbing?) over $120 million in its opening weekend in the U.S. and Canada. But the story leading up to this latest Spider-Man movie has been its own epic saga.

When Marvel licensed the Spider-Man film rights to Sony Pictures in the 1990s, the deal made sense — Marvel didn't make movies yet, and their business was mainly about making comic books and toys. Years later, though, the deal would come back to haunt Marvel, and it would start a long tug of war between Sony and Marvel over who should have creative cinematic control of Marvel's most popular superhero. Today, we break down all of the off-screen drama that has become just as entertaining as the movies themselves.

'Tis the season for Americans to head out in droves and bring home a freshly-cut Christmas tree. But decorative evergreens don't just magically show up on corner lots, waiting to find a home in your living room. There are a bunch of fascinating steps that determine exactly how many Christmas trees get sold, and how expensive they are.

Today on the show, we visit the world's largest auction of Christmas trees — and then see how much green New Yorkers are willing to throw down for some greenery. It's a story where snow-dusted Yuletide dreams meet the hard reality of supply and demand. We've got market theory, a thousand dollars in cash, and a "decent sized truck"... anything could happen.

Union membership in the U.S. has been declining for decades. But, in 2022, support for unions among Americans was the highest it's been in decades. This dissonance is due, in part, to the difficulties of one important phase in the life cycle of a union: setting up a union in the first place. One place where that has been particularly clear is at the Volkswagen plant in Chattanooga, Tennessee.

Back in 2008, Volkswagen announced that they would be setting up production in the United States after a 20-year absence. They planned to build a new auto manufacturing plant in Chattanooga.

Volkswagen has plants all over the world, all of which have some kind of worker representation, and the company said that it wanted that for Chattanooga too. So, the United Auto Workers, the union that traditionally represents auto workers, thought they would be able to successfully unionize this plant.

They were wrong.

In this episode, we tell the story of the UAW's 10-year fight to unionize the Chattanooga plant. And, what other unions can learn from how badly that fight went for labor.

In 1794, George Washington decided to raise money for the federal government by taxing the rich. He did it by putting a tax on horse-drawn carriages.

The carriage tax could be considered the first federal wealth tax of the United States. It led to a huge fight over the power to tax in the U.S. Constitution, a fight that continues today.

Back in 2016, things were pretty bad in Venezuela. Grocery stores didn't have enough food. Hospitals didn't have basic supplies, like gauze. Child mortality was spiking. Businesses were shuttering. It's one of the epic economic collapses of our time. And it was totally avoidable.

Venezuela used to be a relatively rich country. It has just about all the economic advantages a country could ask for: Beautiful beaches and mountains ready for tourism, fertile land good for farming, an educated population, and oil, lots and lots of oil.

But during the boom years, the Venezuelan government made some choices that add up to an economic time bomb.

Today on the show, we have an economic horror story about a country that made all the wrong decisions with its oil money. It's a window into the fundamental way that money works and how when you try to control it, you can lose everything.

Then, an update on Venezuela today. How it went from a downward spiral, to a tentative economic stabilization... amidst political upheaval.

Back in the 90s, the federal government ran a bold experiment, giving people vouchers to move out of high-poverty neighborhoods into low-poverty ones. They wanted to test if housing policy could be hope – whether an address change alone could improve jobs, earnings and education.

The answer to that seems obvious. But it did not at all turn out as they expected.

Years later, when new researchers went back to the data on this experiment, they stumbled on something big. Something that is changing housing policy across the country today.
