- C. Active network connections are tracked so that invalid "response" traffic can be identified.
- D. A current baseline of application configurations is maintained and any mis-configuration is responded to promptly.
Answer: C
Explanation:
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.
NEW QUESTION # 26
The Intent of assigning a risk ranking to vulnerabilities Is to?
- A. Ensure all vulnerabilities are addressed within 30 days.
- B. Ensure that critical security patches are installed at least quarterly
- C. Replace the need for quarterly ASV scans.
- D. Prioritize the highest risk items so they can be addressed more quickly.
Answer: D
Explanation:
Intent of Risk Ranking
* PCI DSS Requirement 6.3.2 requires that entities assign a risk ranking to vulnerabilities to prioritize remediation efforts.
* This ensures that the most critical vulnerabilities are addressed in a timely manner, reducing the risk to the CDE.
Practical Implementation
* Vulnerabilities are assessed based on potential impact and likelihood of exploitation, typically using industry-standard frameworks like CVSS.
* High-risk vulnerabilities may require immediate attention, while lower-priority issues are remediated per schedule.
Incorrect Options
* Option A: PCI DSS does not mandate a 30-day remediation window for all vulnerabilities; remediation timelines depend on risk.
* Option B: Quarterly ASV scans are still required even with risk ranking.
* Option D: Installing patches quarterly does not align with the dynamic prioritization of risks.

NEW QUESTION # 28
Which systems must have anti-malware solutions?
- A. All CDE systems, connected systems.NSCs, and security-providing systems.
- B. Any in-scope system except for those identified as 'not at risk' from malware.
- C. All systems that store PAN.
- D. All portable electronic storage.
Answer: B
Explanation:
Scope of Anti-Malware Requirements
* PCI DSS Requirement 5 mandates the use of anti-malware solutions on all in-scope systems unless the system is specifically documented as not being at risk from malware.
* Examples of systems not at risk include those using operating systems that do not support anti-malware tools, provided proper justifications and alternative controls are implemented.
Assessment Considerations
* QSAs must verify and document why a system is considered "not at risk."
* Systems storing, processing, or transmitting cardholder data or that could impact the CDE are generally in-scope for anti-malware.
Incorrect Options
* Option A: While CDE systems and connected systems require protection, the requirement applies specifically to systems at risk from malware.
* Option B: Portable electronic storage is not explicitly called out for universal anti-malware but must be controlled in line with overall security policies.
* Option C: Systems storing PAN are only a subset of in-scope systems.
NEW QUESTION # 29
Which scenario describes segmentation of the cardholder data environment (CDE) for the purposes of reducing PCI DSS scope?
- A. A network configuration that prevents all network traffic between the CDE and out-of-scope networks.
- B. Routers that monitor network traffic flows between the CDE and out-of-scope networks.
- C. Firewalls that log all network traffic flows between the CDE and out-of-scope networks.
- D. Virtual LANs that route network traffic between the CDE and out-of-scope networks.
Answer: A
Explanation:
Segmentation Defined
* PCI DSS v4.0 specifies that effective segmentation separates the CDE from out-of-scope environments, minimizing the risk of unauthorized access to cardholder data.
Key Requirements for Segmentation
* Network traffic between the CDE and out-of-scope networks must be completely prevented. This ensures that out-of-scope systems cannot introduce risks to the CDE.
* Methods like firewalls, ACLs (Access Control Lists), and other technologies may be used to enforce segmentation.
Incorrect Options
* Monitoring or logging traffic (Options A and B) without preventing access does not achieve segmentation.
* Virtual LANs (Option C) alone are insufficient unless properly configured to enforce traffic isolation.
