Software Security Framework Overview

PCI SSC's Software Security Framework (SSF) encompasses Secure Software Standard and Secure Software Lifecycle (Secure SLC) Standard.

Software developed under the Secure SLC Standard adheres to security-by-design principles and can leverage the SSF during PCI DSS assessments.

Applicability

The framework is primarily for software developed by entities or third parties adhering to PCI SSC standards.

It does not apply to legacy payment software listed under PA-DSS unless migrated to SSF.

Incorrect Options

Option A: Not all payment software qualifies; it must align with SSF requirements.

Option B: PCI PTS devices are subject to different security requirements.

Option C: PA-DSS-listed software does not automatically meet SSF standards without reassessment.

Key Management Requirements:

PCI DSS Requirement 3.5 specifies the protection of cryptographic keys, including encryption, storage in secure cryptographic devices (SCDs), or as key components to ensure security and prevent unauthorized access.

Clarifications on Cryptographic Key Protection:

A/B: Public keys and key strength requirements are not specified in this context.

D: Separation of duties mandates that key-encrypting and data-encrypting keys must not be assigned to the same custodian.

Testing and Validation:

QSAs verify compliance by examining key management practices, storage mechanisms, and access controls for cryptographic keys during the assessment.

PCI DSS Requirement:

Requirement 11.4 mandates the implementation of intrusion detection and/or intrusion prevention techniques to alert personnel of suspected compromises within the cardholder data environment (CDE).

Purpose of IDS/IPS:

These systems are deployed to identify potential threats and alert relevant personnel, enabling them to take corrective actions to prevent data breaches.

Rationale Behind Correct Answer:

A: Intrusion detection is required only for in-scope components, not all system components.

C/D: Intrusion detection systems do not perform isolation or identification of all cardholder data; they monitor for and alert on potential intrusions.

Audit Log Retention Requirements

PCI DSS Requirement 10.7 specifies audit logs must be retained for a minimum of one year. The most recent three months must be immediately accessible for incident analysis and reporting.

Purpose of Log Retention

Retaining logs aids in forensic investigations, regulatory compliance, and operational oversight.

Incorrect Options

Options B, C, and D specify durations that are not consistent with PCI DSS requirements.

Role of the Assessor in Verifying Segmentation

PCI DSS v4.0 requires assessors to confirm that segmentation controls (firewalls, ACLs, etc.) effectively isolate the CDE from out-of-scope networks.

Proper configuration and functionality testing ensure that only authorized traffic can access the CDE.

Testing Requirements

Methods include network scans, configuration reviews, and traffic analysis to verify the segmentation is functioning as intended.

Incorrect Options

Option A: Verifying traffic flow is part of the task but not the primary goal.

Option B: Payment brands do not approve segmentation controls.

Option C: Use of specific devices is not mandated for segmentation.
