Secaudit Tool - Comprehensive Security Audit

Systematic OWASP-based security assessment with compliance evaluation through workflow-driven investigation

The secaudit tool provides comprehensive security auditing capabilities with systematic OWASP Top 10 assessment, compliance framework evaluation, and threat modeling. This workflow tool guides Claude through methodical security investigation steps with forced pauses between each step to ensure thorough vulnerability assessment, security pattern analysis, and compliance verification before providing expert analysis.

Important: AI models may not identify all security vulnerabilities. Always perform additional manual security reviews, penetration testing, and verification.

Example Prompts 

Perform a secaudit on this e-commerce web application focusing on payment processing security and PCI DSS compliance

Use bab's secaudit to conduct a comprehensive security audit of the authentication system, threat level high,
focus on enterprise security patterns and HIPAA compliance

Pro Tip – Multi-Scope Security Assessment:

Start separate sub-tasks: in one run a secaudit for critical payment processing components focusing on PCI DSS,
and in the other for user management focusing on OWASP authentication vulnerabilities, then combine into a
unified security remediation plan using planner

How It Works

The secaudit tool implements a structured 6-step security workflow that ensures comprehensive security assessment:

Investigation Phase (Claude-Led):

  1. Step 1: Security Scope Analysis - Claude identifies application type, tech stack, attack surface, and compliance requirements
  2. Step 2: Authentication & Authorization Assessment - Analyzes auth mechanisms, session management, and access controls
  3. Step 3: Input Validation & Data Security - Reviews input handling, data protection, and injection vulnerabilities
  4. Step 4: OWASP Top 10 (2021) Review - Systematic assessment of all OWASP categories with specific findings
  5. Step 5: Dependencies & Infrastructure - Security analysis of third-party components and deployment configurations
  6. Step 6: Compliance & Risk Assessment - Evaluation against specified compliance frameworks and risk prioritization

Expert Analysis Phase: After Claude completes the investigation (unless confidence is certain):

  • Complete security assessment summary with all vulnerabilities and evidence
  • OWASP Top 10 systematic findings with severity classifications
  • Compliance framework gap analysis and remediation recommendations
  • Risk-prioritized remediation roadmap based on threat level and business impact

Best Practices

  • Define clear security scope: Specify application type, tech stack, and security boundaries via security_scope
  • Set appropriate threat levels: Match assessment depth to risk exposure and criticality
  • Include compliance requirements: Specify relevant frameworks for regulatory alignment
  • Use parallel audits: Run separate assessments for different components or compliance frameworks
  • Provide architectural context: Include system diagrams, data flow documentation, or deployment topology
  • Focus audit scope: Use audit_focus for targeted assessments of specific security domains
  • Filter by severity: Use severity_filter to focus on the most critical findings first
  • Follow up on findings: Use continuation_id to dive deeper into specific vulnerabilities
