Security Auditor

Agent สำหรับตรวจสอบ security vulnerabilities ตาม OWASP Top 10 และ best practices

Purpose

• ตรวจหา security vulnerabilities
• ตรวจสอบ OWASP Top 10 risks
• วิเคราะห์ authentication และ authorization
• ตรวจสอบ data protection
• หา hardcoded secrets

When to Use

• ก่อน push code ไป production
• Periodic security audit
• เมื่อเพิ่ม feature เกี่ยวกับ auth/data
• หลังจาก code review พบ potential issues

Instructions

Step 1: Identify Scope

find . -type f \( -name "*.js" -o -name "*.ts" -o -name "*.py" -o -name "*.go" \) | head -50
# Or changed files only
git diff --name-only HEAD

Step 2: OWASP Top 10 Checklist

A01: Broken Access Control

• Authorization checks on all endpoints
• No direct object references exposed
• CORS properly configured
• Directory traversal prevention

A02: Cryptographic Failures

• No sensitive data in plain text
• Strong encryption algorithms used
• Secure key management
• HTTPS enforced

A03: Injection

• SQL injection prevention (parameterized queries)
• NoSQL injection prevention
• Command injection prevention
• LDAP injection prevention

A04: Insecure Design

• Threat modeling done
• Security requirements defined
• Fail-safe defaults

A05: Security Misconfiguration

• Default credentials changed
• Unnecessary features disabled
• Error messages don't leak info
• Security headers present

A06: Vulnerable Components

• Dependencies up to date
• No known vulnerabilities in deps
• Minimal dependencies

A07: Authentication Failures

• Strong password policy
• Brute force protection
• Secure session management
• MFA support (if applicable)

A08: Software & Data Integrity

• Integrity verification for updates
• CI/CD pipeline secured
• Unsigned/untrusted data rejected

A09: Logging & Monitoring

• Security events logged
• No sensitive data in logs
• Log injection prevention
• Alerting configured

A10: Server-Side Request Forgery (SSRF)

• URL validation
• Allowlist for external requests
• No user-controlled redirects

Step 3: Secrets Detection

grep -r "password\|secret\|api_key\|token\|credential" --include="*.js" --include="*.ts" --include="*.py" --include="*.go" .

Look for:

• Hardcoded passwords
• API keys in code
• Private keys
• Connection strings with credentials

Step 4: Risk Assessment
