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. 

Covered Entities

CIRCIA broadly defined “Covered Entity” to include entities that are in one of the 16 critical infrastructure sectors established under Presidential Policy Directive 21 (“PPD-21”) and directed CISA to develop a more comprehensive definition in subsequent rulemaking.  Accordingly, the Proposed Rule (1) addresses how to determine whether an entity is “in” one of the 16 sectors and (2) proposed two additional criteria for the Covered Entity definition, either of which must be met in order for an entity to be covered.  Notably, the Proposed Rule’s definition of Covered Entity would encompass the entire corporate entity, even if only a constituent part of its business or operations meets the criteria.  Thus, Covered Cyber Incidents experienced by a Covered Entity would be reportable regardless of which part of the organization suffered the impact.  In total, CISA estimates that over 300,000 entities would be covered by the Proposed Rule.

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…

The Federal Energy Regulatory Commission (“FERC”) issued a final rule (Order No. 887) directing the North American Electric Reliability Corporation (“NERC”) to develop new or modified Reliability Standards that require internal network security monitoring (“INSM”) within Critical Infrastructure Protection (“CIP”) networked environments.  This Order may be of interest to entities that develop, implement, or maintain hardware or software for operational technologies associated with bulk electric systems (“BES”).

The forthcoming standards will only apply to certain high- and medium-impact BES Cyber Systems.  The final rule also requires NERC to conduct a feasibility study for implementing similar standards across all other types of BES Cyber Systems.  NERC must propose the new or modified standards within 15 months of the effective date of the final rule, which is 60 days after the date of publication in the Federal Register.  

Background

According to the FERC news release, the 2020 global supply chain attack involving the SolarWinds Orion software demonstrated how attackers can “bypass all network perimeter-based security controls traditionally used to identify malicious activity and compromise the networks of public and private organizations.”  Thus, FERC determined that current CIP Reliability Standards focus on prevention of unauthorized access at the electronic security perimeter and that CIP-networked environments are thus vulnerable to attacks that bypass perimeter-based security controls.  The new or modified Reliability Standards (“INSM Standards”) are intended to address this gap by requiring responsible entities to employ INSM in certain BES Cyber Systems.  INSM is a subset of network security monitoring that enables continuing visibility over communications between networked devices that are in the so-called “trust zone,” a term which generally describes a discrete and secure computing environment.  For purposes of the rule, the trust zone is any CIP-networked environment.  In addition to continuous visibility, INSM facilitates the detection of malicious and anomalous network activity to identify and prevent attacks in progress.  Examples provided by FERC of tools that may support INSM include anti-malware, intrusion detection systems, intrusion prevention systems, and firewalls.   Continue Reading FERC Orders Development of New Internal Network Security Monitoring Standards

On April 20, 2022, the cybersecurity authorities of the United States, Australia, Canada, New Zealand, and the United Kingdom—the so-called “Five Eye” governments—announced the publication of Alert AA22-110A, a Joint Cybersecurity Advisory (the “Advisory”) warning critical infrastructure organizations throughout the world that the Russian invasion of Ukraine could expose them “to increased malicious cyber activity from Russian state-sponsored cyber actors or Russian-aligned cybercrime groups.”  The Advisory is intended to update a January 2022 Joint Cybersecurity Advisory, which provided an overview of Russian state-sponsored cyber operations and tactics, techniques, and procedures (“TTPs”).

In its announcement, the authorities urged critical infrastructure network defenders in particular “to prepare for and mitigate potential cyber threats by hardening their cyber defenses” as recommended in the Advisory.

Overview.  The Advisory notes that “evolving intelligence” indicates that the Russian government is exploring options for potential cyber attacks and that some cybercrime groups have recently publicly pledged support for the Russian government and threatened to conduct cyber operations on behalf of the Russian government.  The Advisory summarizes TTPs used by five state-sponsored advanced persistent threat (“APT”) groups, two Russian-aligned cyber threat groups, and eight Russian-aligned cybercrime groups.  Additionally, it provides a list of mitigations and suggests that critical infrastructure organizations should implement certain mitigations “immediately.”

Russian State-Sponsored Cyber Operations.  The Advisory notes that Russian state-sponsored cyber actors have “demonstrated capabilities” to compromise networks; maintain long-term, persistent access to networks; exfiltrate sensitive data from information technology (“IT”) and operational technology (“OT”) networks; and disrupt critical industrial control systems (“ICS”) and OT networks by deploying destructive malware.  The Advisory details five Russian APT groups:
