PCI DSS Secure Coding for C/C++ Payment Software with CppDepend

PCI DSS (Payment Card Industry Data Security Standard) applies to every system that stores, processes or transmits cardholder data. Requirement 6 demands secure software development: coding standards based on industry best practices, protection against common vulnerabilities (injection, buffer overflows, improper error handling), and code review processes. For C/C++ payment terminals, gateways and trading infrastructure, that means provable, continuous control of memory safety and input handling.

PCI DSS Requirement 6 and C/C++

• 6.2/6.3 — Secure development: software developed under documented secure coding standards.
• Common vulnerability coverage: buffer overflows, injection flaws, insecure cryptographic storage, improper error handling.
• Code review: manual or automated review of code changes before release to production.
• Change control: every change tracked, verified and separated between dev/test and production.

How CppDepend Supports PCI DSS Programs

• Built-in CERT C/C++ and CWE rule sets covering the weakness classes PCI DSS names explicitly.
• Custom CQLinq rules: enforce your secure coding standard — banned functions, mandatory bounds checks, crypto API usage, PAN data-flow restrictions.
• Automated code review: every pull request analyzed with the same rules; violations block the merge.
• Data-flow awareness: dependency graphs show which components can reach cardholder-data paths — and keep them minimal.
• Audit evidence: timestamped compliance reports for QSA assessments.
