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.   

New or Modified Reliability Standards

The INSM Standards will apply to all high-impact BES Cyber Systems and medium-impact BES Cyber Systems with external routable connectivity, defined as the ability to access a BES Cyber System from outside of its associated electronic security perimeter.  FERC declined to set an implementation timeframe for the forthcoming standards and instead directed NERC to recommend an implementation period when it submits its proposal.  Accordingly, the deadline for responsible entities to implement INSM could be years in the future.

Under the rule, the INSM Standards must:

  • (1) Address the need for responsible entities to develop baselines of their network traffic inside their CIP-networked environment; 
  • (2) Address the need for responsible entities to monitor for and detect unauthorized activity, connections, devices, and software inside the CIP-networked environment; and
  • (3) Require responsible entities to identify anomalous activity to a high level of confidence by:
    • (a) Logging network traffic;
    • (b) Maintaining logs and other data collected regarding network traffic; and
    • (c) Implementing measures to minimize the likelihood of an attacker removing evidence of their tactics, techniques, and procedures from compromised devices.

Feasibility Study

Within 12 months of the final rule, NERC must also submit a report that studies the feasibility of implementing INSM within medium-impact BES Cyber Systems without external routable connectivity and all low-impact BES Cyber Systems, which are not subject to the INSM Standards.

FERC has emphasized that the commissioned feasibility study should include a determination of:

(1) The ongoing risk to the reliability and security of the Bulk-Power System posed by low and medium-impact BES Cyber Systems that will not be subject to the INSM Standards; and (2) The potential technological or other challenges involved in extending INSM to additional BES Cyber Systems, as well as possible alternative mitigating actions to address the risks posed.

Ashden Fein is a vice chair of the firm’s global Cybersecurity practice. He advises clients on cybersecurity and national security matters, including crisis management and incident response, risk management and governance, government and internal investigations, and regulatory compliance.

For cybersecurity matters, Ashden counsels clients on preparing for and responding to cyber-based attacks, assessing security controls and practices for the protection of data and systems, developing and implementing cybersecurity risk management and governance programs, and complying with federal and state regulatory requirements. Ashden frequently supports clients as the lead investigator and crisis manager for global cyber and data security incidents, including data breaches involving personal data, advanced persistent threats targeting intellectual property across industries, state-sponsored theft of sensitive U.S. government information, extortion and ransomware, and destructive attacks.

Additionally, Ashden assists clients from across industries with leading internal investigations and responding to government inquiries related to the U.S. national security and insider risks. He also advises aerospace, defense, and intelligence contractors on security compliance under U.S. national security laws and regulations including, among others, the National Industrial Security Program (NISPOM), U.S. government cybersecurity regulations, FedRAMP, and requirements related to supply chain security.

Before joining Covington, Ashden served on active duty in the U.S. Army as a Military Intelligence officer and prosecutor specializing in cybercrime and national security investigations and prosecutions — to include serving as the lead trial lawyer in the prosecution of Private Chelsea (Bradley) Manning for the unlawful disclosure of classified information to Wikileaks.

Ashden currently serves as a Judge Advocate in the
U.S. Army Reserve.

Caleb Skeath advises clients on a broad range of cybersecurity and privacy issues, including cybersecurity incident response, cybersecurity and privacy compliance obligations, internal investigations, regulatory inquiries, and defending against class-action litigation. Caleb holds a Certified Information Systems Security Professional (CISSP) certification.

Caleb specializes in assisting clients in responding to a wide variety of cybersecurity incidents, ranging from advanced persistent threats to theft or misuse of personal information or attacks utilizing destructive malware. Such assistance may include protecting the response to, and investigation of an incident under the attorney-client privilege, supervising response or investigation activities and interfacing with IT or information security personnel, and advising on engagement with internal stakeholders, vendors, and other third parties to maximize privilege protections, including the negotiation of appropriate contractual terms. Caleb has also advised numerous clients on assessing post-incident notification obligations under applicable state and federal law, developing communications strategies for internal and external stakeholders, and assessing and protecting against potential litigation or regulatory risk following an incident. In addition, he has advised several clients on responding to post-incident regulatory inquiries, including inquiries from the Federal Trade Commission and state Attorneys General.

In addition to advising clients following cybersecurity incidents, Caleb also assists clients with pre-incident cybersecurity compliance and preparation activities. He reviews and drafts cybersecurity policies and procedures on behalf of clients, including drafting incident response plans and advising on training and tabletop exercises for such plans. Caleb also routinely advises clients on compliance with cybersecurity guidance and best practices, including “reasonable” security practices.

Caleb also maintains an active privacy practice, focusing on advising technology, education, financial, and other clients on compliance with generally applicable and sector-specific federal and state privacy laws, including FERPA, FCRA, GLBA, TCPA, and COPPA. He has assisted clients in drafting and reviewing privacy policies and terms of service, designing products and services to comply with applicable privacy laws while maximizing utility and user experience, and drafting and reviewing contracts or other agreements for potential privacy issues.
