When you’re ready to bring compliance into one place
How to Audit ISO 27001 Annex A 8.28 Secure Coding
- Inspect Secure Coding Guidelines: Review secure coding standards stored in SharePoint to confirm rules governing input validation, output encoding, memory management, and error handling are documented and enforced across development teams.
- Audit Static Application Security Testing (SAST): Inspect automated code scanning configurations and pipeline logs to verify static code analysis runs automatically on code commits, with identified vulnerabilities tracked in Jira.
- Verify Secret Management in Repositories: Audit automated secret scanner results to confirm hardcoded passwords, private keys, and API tokens are detected, blocked from git branches, and remediated via version control logs.
- Sample Peer Code Review Records: Sample pull requests and review logs in Confluence across active software projects to verify peer code reviews are mandatory, documented, and check for security flaws before merging into protected branches.
- Check Software Composition Analysis (SCA): Review SCA logs and Software Bill of Materials (SBOM) records in SharePoint to verify third-party libraries, frameworks, and open-source dependencies are scanned for known vulnerabilities (CVEs).
- Audit Developer Training & Competency: Sample training records in SharePoint to confirm software developers and engineers receive regular, role-specific training on secure coding practices and common vulnerability prevention.
- Verify Secure Refactoring & Legacy Code Remediation: Inspect Jira vulnerability tracking logs to confirm legacy code debt and secure coding flaws identified during code reviews or penetration tests are remediated according to defined SLAs.
- Inspect Source Code Repository Protections: Review access controls and branch protection rules in version control systems to ensure main branches restrict direct force-pushing and require passing security gate checks.
- Verify Security Acceptance Verification: Inspect Jira release tickets to verify that lead developers have explicitly signed off on secure coding compliance before production merges.
- Audit Exception Management: Review centralized SharePoint exception registers to ensure any temporary secure coding waivers or legacy code risks have documented management approval and compensating controls.
Audit Evidence Checklist
- Secure Coding Policy & Guidelines: Present version-controlled Secure Coding Standards stored in SharePoint, showing documented approval metadata and revision history.
- Jira Sprint Security Tickets: Supply Jira user stories and developer task histories demonstrating embedded security acceptance criteria and pre-release security verification.
- Confluence Peer Code Review Records: Provide documented peer code review logs, pull request review summaries, and lead developer approval records published in Confluence.
- Developer Security Training Minutes: Produce formal meeting notes and attendance logs from developer security briefings and annual secure coding training sessions.
- Library & Framework Version Histories: Share version control histories and Software Composition Analysis (SCA) logs detailing approved internal coding libraries and third-party dependency updates.
- Automated SAST & Secret Scanning Logs: Present automated static analysis and git secret detection reports, accompanied by corresponding Jira tickets for remediated flaws.
- Approved Coding Exception Logs: Provide formal exception register records in SharePoint detailing approved temporary secure coding waivers, legacy code risks, and compensating controls.
What to Teach Employees
- Master OWASP Top 10 Prevention Tactics: Train developers on language-specific secure coding practices to eliminate injection flaws, cross-site scripting (XSS), broken access controls, and insecure deserialization.
- Enforce Strict Input Validation and Output Encoding: Teach software engineers to sanitize, validate, and type-check all incoming data streams while encoding output to prevent malicious code execution.
- Never Commit Hardcoded Secrets: Remind developers to store API tokens, private keys, database credentials, and service passwords in secure key vaults rather than placing them in source code or configuration files.
- Conduct Thorough Security-Focused Code Reviews: Train peer reviewers to actively inspect pull requests for security vulnerabilities and logic flaws in Confluence rather than reviewing solely for functional feature completeness.
- Manage and Update Third-Party Dependencies: Teach development teams to run Software Composition Analysis (SCA) scans routinely and keep open-source packages and frameworks updated to prevent known CVE exposures.
- Utilize Automated SAST and Linter Tools: Show software teams how to interpret and resolve security findings generated by Static Application Security Testing (SAST) tools, tracking open issues as Jira tickets during active development.
- Practice Defensive Exception and Error Handling: Train developers to handle application exceptions gracefully without revealing system internal details, stack traces, or sensitive database structures in error messages.
- Report Discovered Code Flaws Promptly: Encourage developers to report zero-day bugs, unmanaged dependency vulnerabilities, or security flaws discovered in existing codebases via designated Jira tickets immediately.
- Reference Documented Coding Standards: Instruct developers and engineering leads where to find master secure coding standards and guidance in SharePoint prior to starting new code tasks.
Common Implementation Challenges
- Developer Resistance to Security Gates: Engineering teams focused on rapid sprint velocity often view static code analysis (SAST) and mandatory security checks as bottlenecks, leading to attempts to bypass rules or defer remediation.
- High Volume of SAST False Positives: Automated static analysis tools frequently flag benign code patterns, causing alert fatigue and leading developers to dismiss critical security findings alongside false alarms.
- Accidental Secret Commits in Git History: Developers inadvertently committing hardcoded API keys, tokens, or private certificates into source control, requiring complex git repository history rewrites and immediate credential revocations.
- Unmanaged Open-Source Dependency Vulnerabilities: Complex, multi-layered dependency chains make tracking, evaluating, and patching transitive CVE vulnerabilities in open-source libraries difficult without breaking application functionality.
- Superficial Peer Code Reviews: Code reviews often focus exclusively on feature logic and code style rather than actively checking for subtle security flaws like improper input sanitization, broken authorization, or unescaped output.
- Legacy Codebases Lacking Standardized Controls: Technical debt in older applications where secure coding practices were not historically enforced, making retroactive refactoring and security patching labor-intensive and risky.
- Lack of Language-Specific Security Skills: Generic annual compliance training failing to equip developers with practical, language-specific secure coding expertise required for their daily development stack.
- Inconsistent Coding Standards Across Teams: Disjointed coding practices across distributed or contracted development teams leading to inconsistent implementation of input validation, error logging, and session handling.
- Disconnect Between Policy and Backlogs: High-level secure coding standards documented in SharePoint often fail to be translated into specific, actionable acceptance criteria in Jira user stories for sprint execution.
