Purpose of Classifying Media

PCI DSS v4.0 emphasizes the need to classify media based on the sensitivity of the data it contains. Media classification ensures appropriate handling, storage, and destruction processes.

Media Protection Requirements

Media containing cardholder data must be securely stored, transferred, and destroyed when no longer needed.

Classification informs the level of protection required, such as encryption, physical security, or controlled access.

Incorrect Options

Option B: Moving media quarterly is not a requirement.

Option C: Labeling as 'Confidential' is insufficient without a comprehensive protection strategy.

Option D: Destruction schedules should depend on retention requirements and data sensitivity, not a universal timeline.

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.

PAN Transmission Protection

PCI DSS Requirement 4.1 mandates strong cryptography for PAN during transmission over both public and private wireless networks to prevent unauthorized interception.

Incorrect Options

Options B and D: PAN protection is not required for private wired networks.

Option C: PAN must be protected during transmission over public wireless networks.

Requirement for Secure Transmission:

PCI DSS Requirement 4.1 mandates that cardholder data sent over open public networks must be protected with strong cryptographic protocols. Accepting only trusted keys ensures data integrity and prevents unauthorized access.

Key Validation Practices:

Trusted keys and certificates are verified to ensure authenticity. Using untrusted keys compromises the security of the encrypted communication.

Prohibited Practices:

A/D: Configuring protocols to accept all certificates or lower encryption strength violates PCI DSS encryption guidelines.

B: Proprietary protocols are not inherently compliant unless they meet strong cryptographic standards.

Testing and Verification:

Assessors verify the implementation of trusted keys by examining encryption settings, reviewing certificate chains, and conducting tests to confirm only trusted connections are accepted.

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.
