ISC2 Governance, Risk and Compliance (CGRC) Practice Question

While applying NIST SP 800-53, you find a legacy industrial controller cannot meet FIPS 140-2 encryption for its internal disk required by SC-28. Pending replacement, which alternate control best provides equivalent protection and maintains compliance?

  • Require daily password changes for all operator accounts and enforce account lockout after three failed logons.

  • Run weekly credentialed vulnerability scans against the controller and review findings within 24 hours.

  • Place the controller in a locked, access-controlled cabinet with 24 × 7 surveillance and tamper-evident seals to prevent unauthorized physical access.

  • Configure mutual TLS on every network interface so all data in transit to and from the controller is encrypted.
