PCI SSC QSA_New_V4 Exam With Confidence Using Practice Dumps

Testing with Live PANs

PCI DSS Requirement 6.4.3 requires that live PANs (Primary Account Numbers) only be used in secure and controlled environments within the CDE.

Pre-production environments located within the CDE must adhere to all PCI DSS requirements for security and monitoring​​.

Prohibited Uses

Testing with live PANs in environments outside the CDE violates PCI DSS. Only simulated data should be used in less secure testing environments.

Incorrect Options

Option A: Production environments are for real transactions, not testing.

Option B: Test environments outside the CDE are insecure for live PANs.

Option D: The QSA environment is irrelevant to the organization’s CDE testing controls.

Key Management Requirements:

PCI DSS Requirement 3.6.5 specifies that when a cryptographic key is retired, it must no longer be used for encryption operations but may still be retained for decryption purposes as needed (e.g., to decrypt historical data until it is re-encrypted with the new key)​.

Secure Key Retirement:

Retired keys should be securely stored or destroyed based on the organization’s key management policy to prevent unauthorized access or misuse.

Reference in PCI DSS Documentation:

Section 3.6.5 emphasizes that retired keys must be rendered inactive for further encryption while allowing use for decryption, ensuring data continuity and compliance​.

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.
