Which of the following is true regarding compensating controls?
- A. A compensating control must address the risk associated with not adhering to the PCI DSS requirement.
- B. A compensating control worksheet is not required if the acquirer approves the compensating control.
- C. An existing PCI DSS requirement can be used as compensating control if it is already implemented.
- D. A compensating control is not necessary if all other PCI DSS requirements are in place.
正解：A
解説：
Compensating Controls Definition and Purpose
* A compensating control is an alternate measure that satisfies the intent of a specific PCI DSS requirement and provides an equivalent level of security.
* The rationale and risk mitigation must be explicitly documented using the Compensating Control Worksheet (CCW).
Mandatory Documentation
* PCI DSS v4.0 mandates the use of a CCW when implementing compensating controls. This applies regardless of acquirer approvals.
* The CCW requires detailed documentation including:
* Constraints preventing the original requirement from being implemented.
* Justification for the compensating control.
* Description of the control and evidence of its effectiveness.
Using Existing Requirements
* If an existing PCI DSS requirement (e.g., Requirement 5 for antivirus) is already implemented and can mitigate the risks of not meeting another requirement, it may qualify as a compensating control.
Approval and Review Process
* QSAs must validate the implementation, effectiveness, and appropriateness of compensating controls during the assessment process

Which of the following describes "stateful responses" to communication Initiated by a trusted network?
- A. Administrative access to respond to requests to change the firewall Is limited to one individual at a time.
- B. A current baseline of application configurations is maintained and any mis-configuration is responded to promptly.
- C. Logs of user activity on the firewall are correlated to identify and respond to suspicious behavior.
- D. Active network connections are tracked so that invalid "response" traffic can be identified.
正解：D
解説：
Stateful Inspection
* PCI DSS Requirement 1.2 specifies the need for stateful inspection to track the state of active connections. This ensures that only valid responses to communication initiated by trusted networks are allowed.
* Invalid or unsolicited response traffic is blocked to prevent exploitation of vulnerabilities.
Key Functionality of Stateful Firewalls
* Stateful firewalls maintain session information and only allow traffic that matches an existing session or expected response.
Incorrect Options
* Option A: Administrative access restrictions are important but unrelated to stateful responses.
* Option C: Baseline configurations are a different security control.
* Option D: Logging and correlation are for threat detection, not stateful response.
