CISA and the National Security Agency (NSA) have published Open Radio Access Network Security Considerations. This product—generated by the Enduring Security Framework (ESF) Open Radio Access Network (RAN) Working Panel, a subgroup within the cross-sector working group— assessed the benefits and security considerations associated with implementing an Open RAN architecture. Focusing on current designs and specification standards, the ESF Open RAN Working Panel examined how security compares with, and is distinct from, traditional, proprietary RANs.
CISA encourages users, network operators, vendors, and stakeholders to review the considerations. For more information, see the ESF’s Open Radio Access Network Security Considerations, peruse CISA’s 5G Library, and visit Securing 5G Open RAN Architecture from Cybersecurity Risks.

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.
