The Cybersecurity Information Sharing Act of 2015 (“CISA 2015”), which provides liability protections and other safeguards for sharing certain cybersecurity information with the U.S. federal government and private entities, was reauthorized as part of the funding bill enacted on February 3, 2026. CISA 2015’s information‑sharing provisions, which had been scheduled to sunset on January 30, 2026, will now remain in effect through September 30, 2026.Continue Reading Cybersecurity Information Sharing Act of 2015 Reauthorized Through September 2026

On December 16, 2025, the U.S. National Institute of Standards and Technology (“NIST”) published a preliminary draft of the Cybersecurity Framework Profile for Artificial Intelligence (“Cyber AI Profile” or “Profile”).  According to the draft, the Cyber AI Profile is intended to “provide guidelines for managing cybersecurity risk related to AI…

The Cybersecurity Information Sharing Act of 2015 (“CISA 2015”), which provides protections for sharing cybersecurity threat information with the federal government and others, was reauthorized under the funding bill to reopen the federal government, which was enacted on November 12, 2025.  The information sharing mechanisms and protections under CISA 2015, which had previously sunset on September 30, 2025, will now extend through January 30, 2026.Continue Reading Cybersecurity Information Sharing Act of 2015 Reauthorized Through January 2026

The U.S. Federal Energy Regulatory Commission (“FERC”) recently issued Order No. 907 (the “Order”), approving a new Critical Infrastructure Protection (“CIP”) Reliability Standard, CIP-015-1.  The new standard will require covered entities that maintain certain bulk electric systems (“BES”) to implement Internal Network Security Monitoring (“INSM”) for network traffic within their “electronic security perimeter,” i.e., the logical border surrounding the network of interconnected devices that comprise a BES Cyber System.  However, as discussed below, these requirements will not go into effect for approximately three years, and many covered entities will have an additional two years before they are required to comply.Continue Reading FERC Finalizes New Internal Network Security Monitoring Requirements for Bulk Electric Systems

Earlier in April, the U.S. National Institute of Standards and Technology (“NIST”) published Special Publication (“SP”) 800-61, Incident Response Recommendations and Considerations for Cybersecurity Risk Management, Revision 3 (“NIST SP 800-61”).  NIST SP 800-61 Revision 3 (“Revision 3”) is a significant change, as it not only represents the first update of the document since 2012, but also now maps the document’s recommendations and considerations for incident response to the six functions outlined in the recently-updated NIST Cybersecurity Framework 2.0—Govern, Identify, Protect, Detect, Respond, and Recover.  As a result, Revision 3 includes significant new recommendations and guidance for incident response, and entities should consider reviewing and updating their incident response plans and procedures to incorporate these recommendations, particularly if an entity has aligned its cybersecurity program with the NIST Cybersecurity Framework or used the prior versions of NIST SP 800-61 as a basis for existing incident response plans or procedures.Continue Reading NIST Publishes Updated Incident Response Recommendations and Considerations

On December 24, 2024, New York Governor Kathy Hochul signed into law an amendment to New York General Business Law § 899-aa modifying the state’s data breach notification requirements.  The amended law, which is effective immediately, imposes new requirements businesses must follow when providing notifications following a data breach affecting New York residents.  Specifically, businesses now must disclose data breaches affecting New York residents within thirty days from the discovery of a breach.  Additionally, the amendment adds the New York Department of Financial Services (“NYDFS”) to the list of state regulators that must be notified whenever a breach requiring notification to New York residents occurs. Continue Reading New York Adopts Amendment to the State Data Breach Notification Law

On March 27, 2024, the U.S. Cybersecurity and Infrastructure Security Agency’s (“CISA”) Notice of Proposed Rulemaking (“Proposed Rule”) related to the Cyber Incident Reporting for Critical Infrastructure Act of 2022 (“CIRCIA”) was released on the Federal Register website.  The Proposed Rule, which will be formally published in the Federal Register on April 4, 2024, proposes draft regulations to implement the incident reporting requirements for critical infrastructure entities from CIRCIA, which President Biden signed into law in March 2022.  CIRCIA established two cyber incident reporting requirements for covered critical infrastructure entities: a 24-hour requirement to report ransomware payments and a 72-hour requirement to report covered cyber incidents to CISA.  While the overarching requirements and structure of the reporting process were established under the law, CIRCIA also directed CISA to issue the Proposed Rule within 24 months of the law’s enactment to provide further detail on the scope and implementation of these requirements.  Under CIRCIA, the final rule must be published by September 2025.

The Proposed Rule addresses various elements of CIRCIA, which will be covered in a forthcoming Client Alert.  This blog post focuses primarily on the proposed definitions of two pivotal terms that were left to further rulemaking under CIRCIA (Covered Entity and Covered Cyber Incident), which illustrate the broad scope of CIRCIA’s reporting requirements, as well as certain proposed exceptions to the reporting requirements.  The Proposed Rule will be subject to a review and comment period for 60 days after publication in the Federal Register. Continue Reading CISA Issues Notice of Proposed Rulemaking for Critical Infrastructure Cybersecurity Incident Reporting

On January 29, 2024, the Department of Commerce (“Department”) published a proposed rule (“Proposed Rule”) to require providers and foreign resellers of U.S. Infrastructure-as-a-Service (“IaaS”) products to (i) verify the identity of their foreign customers and (ii) notify the Department when a foreign person transacts with that provider or reseller to train a large artificial intelligence (“AI”) model with potential capabilities that could be used in malicious cyber-enabled activity. The proposed rule also contemplates that the Department may impose special measures to be undertaken by U.S. IaaS providers to deter foreign malicious cyber actors’ use of U.S. IaaS products.  The accompanying request for comments has a deadline of April 29, 2024.Continue Reading Department of Commerce Issues Proposed Rule to Regulate Infrastructure-as-a-Service Providers and Resellers

In late December 2023, the Federal Communications Commission (“FCC”) published a Report and Order (“Order”) expanding the scope of the data breach notification rules (“Rules”) applicable to telecommunications carriers and interconnected VoIP (“iVoIP”) providers.  The Order makes several notable changes to the prior rules, including broadening the definitions of a reportable “breach” and “covered data,” requiring covered entities to notify the FCC in addition to federal law enforcement of breaches, and modifying certain customer notification requirements.  The Rules are expected to become effective sometime in 2024, after they are reviewed by the Office of Management and Budget and the FCC’s Wireline Competition Bureau (“Bureau”) announces the effective dates by subsequent public notice.Continue Reading The FCC Expands Scope of Data Breach Notification Rules

On July 13, 2023 the White House issued the National Cybersecurity Strategy Implementation Plan (“NCSIP”).  The NCSIP identifies 65 initiatives – to be led by 18 different departments and agencies – that are designed as a roadmap for implementing the U.S. National Cybersecurity Strategy released earlier this year.  This is the first iteration of the plan, which is intended to be an evolving document that the Administration plans to update annually.  Consistent with the Strategy, the NCSIP contemplates five broad lines of effort (“pillars”):

  • Defending critical infrastructure;
  • Disrupting and dismantling threat actors;
  • Shaping market forces to drive security and resilience;
  • Investing in a resilient future; and
  • Forging international partnerships to pursue shared goals.

Among the many initiatives, the Administration has outlined several specific efforts over the next three years that will be of interest to technology companies, federal contractors, and critical infrastructure owners and operators.Continue Reading White House Releases Implementation Plan for the National Cybersecurity Strategy
