ISC2 Governance, Risk and Compliance (CGRC) Practice Question
While tailoring the moderate-impact baseline for an isolated SCADA control system that has no external network interfaces, the ISSO wants to mark AC-17 Remote Access as Not Applicable. Which rationale most appropriately supports this decision in the System Security Plan?
Remote access capabilities are expected to be funded and added during the next project phase, so the control will be addressed later.
Implementing the control would be too costly compared with the perceived risk and is therefore deferred.
A separate corporate security team is responsible for remote access, so the system owner will not address the control.
The system's architecture completely eliminates remote connectivity-no modems, VPN tunnels, wireless, or other external interfaces exist, and all maintenance is performed locally under physical escort.
A control can be marked Not Applicable only when the system's design or operational context makes the requirement irrelevant. Because the SCADA system is physically and logically isolated-no modems, VPNs, wireless radios, or other external interfaces exist-there is simply no technical means to establish remote sessions. In that circumstance, the protections required by AC-17 cannot be implemented because remote access cannot occur; the control is therefore legitimately outside the scope of the system and may be documented as Not Applicable. The other statements reflect cost, scheduling, or organizational considerations; those concerns do not negate a control's applicability and would instead require acceptance of residual risk or creation of a POA&M, not an N/A designation.
