On October 16, 2024, the U.S. Cybersecurity and Infrastructure Security Agency (“CISA”) and the Federal Bureau of Investigation (“FBI”) published guidance on Product Security Bad Practices (the “Guidance”) that identifies “exceptionally risky” product security practices for software manufacturers.  The Guidance states that the ten identified practices—categorized as (1) Product Properties, (2) Security Features, or (3) Organizational Processes and Policies—are “dangerous and significantly elevate[] risk to national security, national economic security, and national public health and safety.”

The Guidance offers recommendations to remediate each of the identified practices and states that adoption of the recommendations indicates software manufacturers “are taking ownership of customer security outcomes.”  Provided below are the ten practices and associated recommendations.Continue Reading CISA and FBI Publish Product Security Bad Practices

On October 16, 2024, the New York Department of Financial Services (“NYDFS”) issued an industry letter (the “Guidance”) highlighting the cybersecurity risks arising from the use of artificial intelligence (“AI”) and providing strategies to address these risks.  While the Guidance “does not impose any new requirements,” it clarifies how Covered Entities should address AI-related risks as part of NYDFS’s landmark cybersecurity regulation, codified at 23 NYCRR Part 500 (“Cybersecurity Regulation”).  The Cybersecurity Regulation, as revised in November 2023, requires Covered Entities to implement certain detailed cybersecurity controls, including governance and board oversight requirements.  Covered Entities subject to the Cybersecurity Regulation should pay close attention to the new Guidance not only if they are using or planning on using AI, but also if they could be subject to any of the AI-related risks or attacks described below. Continue Reading NYDFS Issues Industry Guidance on Risks Arising from Artificial Intelligence

On September 17, 2024, the U.S. Cybersecurity and Infrastructure Security Agency (“CISA”) and the Federal Bureau of Investigation (“FBI”) published a Secure by Design Alert, cautioning senior executives and business leaders to be aware of and work to eliminate cross-site scripting (“XSS”) vulnerabilities in their products (the “Alert”).  XSS vulnerabilities allow “threat actors to inject malicious scripts into web applications, exploiting them to manipulate, steal, or misuse data across different contexts.” Continue Reading CISA and FBI Publish a Secure by Design Alert to Eliminate Cross-Site Scripting Vulnerabilities

On February 26, 2024, the U.S. National Institute of Standards and Technology (“NIST”) published version 2.0 of its Cybersecurity Framework.  Originally released in 2014 and updated in 2018 and now 2024, the NIST Cybersecurity Framework (“CSF” or “Framework”) “offers a taxonomy of high-level cybersecurity outcomes that can be used by any organization — regardless of its size, sector, or maturity — to better understand, assess, prioritize, and communicate its cybersecurity efforts.”  Globally, organizations, industries, and government agencies have increasingly relied upon the Framework to establish cybersecurity programs and measure their maturity.  NIST had proposed some potentially significant updates to the Framework in a Concept Paper published on January 19, 2023, which this Version 2.0 follows. Continue Reading NIST Publishes the Cybersecurity Framework 2.0

Earlier this month, the New York Department of Financial Services (“NYDFS”) announced that it had finalized the Second Amendment to its “first-in-the-nation” cybersecurity regulation, 23 NYCRR Part 500.  This Amendment implements many of the changes that NYDFS originally proposed in prior versions of the Second Amendment released for public…

Last week, the U.S. Cybersecurity and Infrastructure Security Agency (“CISA”) released guidance on Security-by-Design and Security-by-Default principles for technology manufacturers that was jointly developed by the Federal Bureau of Investigation and the National Security Agency, as well as cybersecurity authorities in Australia, Canada, United Kingdom, Germany, Netherlands, and New Zealand.  While similar principles have been published in the past, such as those released by the U.S. Federal Trade Commission, this guidance builds on the White House’s recent roll-out of the U.S. National Cybersecurity Strategy and is in line with efforts to encourage a consistent, international approach to software security that emphasizes the responsibilities of software manufacturers across various jurisdictions.  While the guidance primarily focuses on recommendations for technology manufacturers, it also includes recommendations for enterprise customers to “hold their supplying technology manufacturers accountable for the security outcomes of their products.”  CISA and the authoring agencies are seeking feedback on the guidance, and indicated plans to hold future listening sessions to collect feedback. Continue Reading CISA Publishes International Guidance on Implementing Security-by-Design and Security-by-Default Principles for Software Manufacturers and Customers

On March 16, 2023, the Federal Energy Regulatory Commission (“FERC”) approved a new Reliability Standard “adding new requirements focused on supply chain risk management for low impact bulk electric system (“BES”) Cyber Systems.”  Continue Reading FERC Approves New Cybersecurity Requirements for Low Impact Bulk Electric Systems

On March 8, 2023, the United States Department of Health and Human Services (“HHS”), through the Administration for Strategic Preparedness and Response and the Health Sector Coordinating Counsel Joint Cybersecurity Working Group, released an updated version of its Cybersecurity Framework Implementation Guide (the “Guide”) “to help the public and private health care sectors prevent cybersecurity incidents.”  Specifically, the Guide aims to help healthcare organizations leverage the NIST Cybersecurity Framework to “determine their cybersecurity goals, assess their current cybersecurity practices, or lack thereof, and help identify gaps for remediation.”  Continue Reading HHS Releases Guidance to Help Healthcare Organizations Align with the NIST Cybersecurity Framework

On March 3, 2023, the United States Environmental Protection Agency (“EPA”) published a memorandum requiring states to evaluate the cybersecurity of operational technology used by public water systems (“PWSs”) “when conducting PWS sanitary surveys or through other state programs.”  EPA’s memorandum “interprets the regulatory requirements relating to the conduct of…

On March 7, 2023, the United States Transportation Security Administration (“TSA”) announced the issuance of new cybersecurity requirements for airport and aircraft operators on an emergency basis.  “The new emergency amendment requires that impacted TSA-regulated entities develop an approved implementation plan that describes measures they are taking to improve their cybersecurity resilience and prevent disruption and degradation to their infrastructure.”Continue Reading TSA Issues New Cybersecurity Requirements for Airport and Aircraft Operators
