Considerations for Critical Infrastructure Operators Working With Third-Party ICS Integrators
Summary
CISA and the FBI have released guidance for critical infrastructure operators on managing risks associated with third-party industrial control system (ICS) integrators. The fact sheet emphasizes the importance of applying the principle of least privilege (PoLP) and establishing secure practices to prevent malicious actors from exploiting access granted to integrators.
IFF Assessment
The article highlights risks and vulnerabilities associated with third-party ICS integrators, which can be exploited by malicious actors to compromise critical infrastructure.
Defender Context
Critical infrastructure operators must be vigilant when engaging third-party ICS integrators, as these relationships can introduce significant supply chain and access risks. Implementing strict access controls, such as the principle of least privilege, and ensuring clear security requirements are enforced throughout the integration process are crucial for preventing unauthorized access and potential disruption.
