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

Risk Level	Criteria
Critical	Exploitable, high impact
High	Exploitable, medium impact
Medium	Requires conditions to exploit
Low	Minimal impact
