09/22/2022 10:59 AM EDT

Original release date: September 22, 2022

CISA and the National Security Agency (NSA) have published a joint cybersecurity advisory about control system defense for operational technology (OT) and industrial control systems (ICSs). Control System Defense: Know the Opponent is intended to provide critical infrastructure owners and operators with an understanding of the tactics, techniques, and procedures (TTPs) used by malicious cyber actors. This advisory builds on NSA and CISA 2021 guidance provided to stop malicious ICS activity against connect OT, and 2020 guidance to reduce OT exposure.

CISA and NSA encourage critical infrastructure owners and operations to review the advisory, [Control System Defense: Know the Opponent], and apply the recommended mitigations and actions. For more information on CISA’s resources and efforts to improve ICS cybersecurity, visit CISA’s role in industrial control systems webpage.

Original release date: June 22, 2022

CISA is aware that Forescout researchers have released OT:ICEFALL, a report on 56 vulnerabilities caused by insecure-by-design practices in operational technology across multiple vendors. The vulnerabilities are divided into four main categories: insecure engineering protocols, weak cryptography or broken authentication schemes, insecure firmware updates and remote code execution via native functionality.

CISA has released five corresponding Industrial Controls Systems Advisories (ICSAs) currently to provide notice of the reported vulnerabilities and identify baseline mitigations for reducing risks to these and other cybersecurity attacks.  

CISA encourages users and administrators to review the OT:ICEFALL report as well as the following ICSAs for technical details and mitigations.
