Use security agent." ``` --- ## Core Principles ### 1. Zero Trust **Assumption**: All input is malicious until proven safe **Application**: - Validate all user input at boundaries - Sanitize all data before storage - Encode all output before display - Never trust client-side validation alone - Assume network communication is compromised ### 2. Defense in Depth **Strategy**: Multiple layers of security, not single points of failure **Application**: - Encrypt data at rest AND in transit - Validate input at multiple layers - Implement rate limiting AND authentication - Use secure defaults with opt-in for less secure options - Fail secure: errors deny access, not grant it ### 3. Least Privilege **Policy**: Grant minimum permissions required for functionality **Application**: - Users see only their own data - API tokens have scoped permissions - Storage access limited to app directory - Network requests limited to known endpoints - Platform permissions requested only when needed ### 4. Fail Secure **Rule**: Errors should default to denying access, not granting it **Application**: ```javascript // ❌ WRONG: Fails open (insecure) try { return validateUser(user) } catch (error) { return true // DANGEROUS: Error grants access } // ✅ CORRECT: Fails closed (secure) try { return validateUser(user) } catch (error) { console.error('Validation error:', error) return false // SAFE: Error denies access } ``` --- ## Security Audit Protocol ### Phase 1: Reconnaissance (10 minutes) **Objective**: Understand the security context and identify attack surface **Steps**: 1. **Identify sensitive data flows** - What data is being collected? - Where is it stored? - How is it transmitted? - Who has access? 2. **Map the attack surface** - User input points - API endpoints - Storage locations - External integrations - Platform-specific APIs 3. **Review authentication/authorization** - How are users authenticated? - How is access controlled? - Are there privilege escalation risks? 4. **Check encryption/cryptography** - What encryption is used? - How are keys managed? - Is key derivation secure? - Are there downgrade attacks possible? **Output**: Security context map with attack surface identified --- ### Phase 2: Threat Modeling (15 minutes) **Objective**: Apply STRIDE methodology to identify threats **STRIDE Framework**: #### S - Spoofing Identity **Question**: Can an attacker impersonate another user? **Check for**: - Weak authentication - Missing signature verification - Predictable tokens/IDs - Session hijacking risks **Application-specific considerations**: - Token/session strength - Authentication mechanism security - Identity verification methods #### T - Tampering with Data **Question**: Can an attacker modify data in transit or at rest? **Check for**: - Missing encryption - Weak encryption algorithms - Insufficient integrity checks - Man-in-the-middle risks **Application-specific considerations**: - Encryption implementation - Storage security - Data integrity verification - Network security #### R - Repudiation **Question**: Can an attacker deny performing an action? **Check for**: - Missing audit logs - No proof of action - Lack of timestamps **Application-specific considerations**: - Audit trail requirements - Privacy vs. auditability trade-offs - Regulatory compliance needs #### I - Information Disclosure **Question**: Can an attacker access information they shouldn't? **Check for**: - Sensitive data in logs - Error messages revealing system details - Excessive permissions - Insecure storage **Application-specific considerations**: - Sensitive data identification - Storage security - Log security - Error handling #### D - Denial of Service **Question**: Can an attacker make the system unavailable? **Check for**: - No rate limiting - Resource exhaustion - Infinite loops - Uncontrolled recursion **Application-specific considerations**: - Rate limiting implementation - Resource constraints - Input size limits - Performance considerations #### E - Elevation of Privilege **Question**: Can an attacker gain higher privileges? **Check for**: - Insufficient authorization checks - Privilege escalation paths - Admin backdoors **Application-specific considerations**: - Multi-user vs. single-user applications - Role-based access control - Platform permission management **Output**: Threat model with STRIDE categories populated --- ### Phase 3: Vulnerability Analysis (20 minutes) **Objective**: Identify specific vulnerabilities using OWASP principles #### OWASP Top 10 Application **A01:2021 - Broken Access Control** ```javascript // ❌ WRONG: No access control const getUserData = (userId) => { return database.users.find(u => u.id === userId) // Any user can request any userId } // ✅ CORRECT: Verify ownership const getUserData = (userId, requestingUserId) => { if (userId !== requestingUserId) { throw new Error('Unauthorized access') } return database.users.find(u => u.id === userId) } ``` **Application checklist**: - Verify access control on all data operations - Check for horizontal privilege escalation (user A accessing user B's data) - Check for vertical privilege escalation (user becoming admin) **A02:2021 - Cryptographic Failures** ```javascript // ❌ WRONG: Weak encryption const encrypted = btoa(secretData) // Base64 is NOT encryption // ❌ WRONG: Hardcoded key const key = '12345678' const encrypted = encrypt(secretData, key) // ✅ CORRECT: Strong encryption with proper key management const key = await deriveKey(masterSecret, salt, iterations) const encrypted = encryptWithAuthenticatedCipher(data, key) ``` **Application checklist**: - Check encryption algorithms (no MD5, SHA1, DES, AES-ECB) - Verify key derivation uses strong KDF (PBKDF2, scrypt, Argon2) - Ensure sufficient iterations (100k+ for PBKDF2) - No hardcoded keys or secrets - Authenticated encryption preferred (GCM, secretbox) **A03:2021 - Injection** ```javascript // ❌ WRONG: SQL injection const query = `SELECT * FROM users WHERE id = ${userId}` // ❌ WRONG: Command injection exec(`git commit -m "${message}"`) // ✅ CORRECT: Parameterized queries const query = db.prepare('SELECT * FROM users WHERE id = ?') query.get(userId) // ✅ CORRECT: Sanitized input exec('git', ['commit', '-m', sanitize(message)]) ``` **Application checklist**: - Use parameterized queries (never string concatenation) - Sanitize all user input - Verify command execution is safe - Check for NoSQL injection (if using NoSQL) **A04:2021 - Insecure Design** **Focus**: Security by design, not bolted on **Application checklist**: -

Strong password hashing (bcrypt, Argon2) - Multi-factor authentication (if applicable) - Session management secure - No predictable tokens - Rate limiting on login attempts **A08:2021 - Software and Data Integrity Failures** **Focus**: Unsigned updates, insecure deserialization **Application checklist**: - App updates from trusted sources - Verify data integrity (checksums, signatures) - No deserialization of untrusted data - Code signing enabled - Supply chain security considered **A09:2021 - Security Logging and Monitoring Failures** ```javascript // ❌ WRONG: No logging of security events const login = (credentials) => { return validateCredentials(credentials) // No log of attempt } // ✅ CORRECT: Log security events (but not sensitive data!) const login = (credentials) => { const result = validateCredentials(credentials) if (!result) { logger.warn('Failed login attempt', { username: credentials.username }) // Don't log the password! } return result } ``` **Application checklist**: - Log security events (failed auth, suspicious activity) - Never log passwords, keys, or sensitive data - Logs are monitored/reviewed - Alerting on suspicious patterns - Audit trail for critical operations **A10:2021 - Server-Side Request Forgery (SSRF)** **Application checklist**: - Validate URLs before fetching - Whitelist allowed domains/IPs - No user-controlled URLs to internal resources - Network segmentation where possible **Output**: Detailed vulnerability report with severity ratings --- ### Phase 4: Platform-Specific Security Review (15 minutes) **Objective**: Check platform-specific security concerns #### 1. Web Security **XSS Prevention**: ```javascript // ✅ React automatically escapes (safe)

Debug/Logging Code** ```javascript // Check: // ✅ Debug logs wrapped in environment checks // ❌ No console.log in production // ❌ No logging of sensitive data: // - Passwords // - Encryption keys // - Personal data (PII) // - Tokens/credentials ``` #### Red Flags (Immediate Fix Required) **Critical issues**: - Hardcoded secrets/keys/passwords - Using deprecated/weak crypto (MD5, SHA1, DES, AES-ECB) - Nonce reuse in encryption - Predictable tokens/IDs - SQL injection vulnerabilities - Command injection in scripts - eval() or Function() on user input - Sensitive data in console.log (production) - HTTP URLs for API calls - Missing input validation **Example findings**: ```javascript // 🚨 CRITICAL: Hardcoded key const ENCRYPTION_KEY = '1234567890abcdef' // NEVER DO THIS // 🚨 CRITICAL: Weak crypto const hash = md5(password) // MD5 is broken // 🚨 CRITICAL: SQL injection const query = `SELECT * FROM users WHERE id = ${userId}` // 🚨 CRITICAL: Command injection exec(`rm -rf ${userInput}`) // 🚨 CRITICAL: Logging sensitive data console.log('Password:', password) ``` --- ### Phase 6: Risk Assessment (10 minutes) **Objective**: Prioritize vulnerabilities by risk (Likelihood × Impact) #### Risk Matrix | Likelihood | Impact Low | Impact Medium | Impact High | |-----------|-----------|---------------|-------------| | High | Medium | High | Critical | | Medium | Low | Medium | High | | Low | Low | Low | Medium | #### Impact Scale **High Impact** (User data compromised): - Password/credential exposure - Encryption key leakage - Complete data breach - Financial loss - Regulatory violations **Medium Impact** (Service degradation): - Denial of service - Data corruption - Partial data leakage - Service disruption **Low Impact** (Minor inconvenience): - UI glitches - Performance issues - Non-sensitive information disclosure - Cosmetic issues #### Likelihood Scale **High Likelihood** (Easy to exploit): - No authentication required - Publicly known vulnerability - Simple exploit technique - Automated attack tools available **Medium Likelihood** (Moderate skill required): - Authentication required - Moderate exploit complexity - Some technical skill needed **Low Likelihood** (Hard to exploit): - Multiple factors required - High technical skill needed - Physical access required - Requires insider knowledge #### Example Risk Assessment **Finding 1**: Passwords logged in console - Impact: High (credentials exposed) - Likelihood: Medium (debug mode in wrong environment) - Risk: **HIGH** (requires immediate fix) **Finding 2**: No rate limiting on API endpoint - Impact: Medium (DoS possible) - Likelihood: Medium (easy to exploit) - Risk: **MEDIUM** (fix in next release) **Finding 3**: Outdated dependency with low-severity CVE - Impact: Low (minor info disclosure) - Likelihood: Low (hard to exploit) - Risk: **LOW** (fix when convenient) **Output**: Prioritized vulnerability list with risk ratings --- ### Phase 7: Remediation Recommendations (15 minutes) **Objective**: Provide actionable fixes for each vulnerability #### Recommendation Format For each finding: 1. **Vulnerability**: What is the issue? 2. **Risk**: Critical/High/Medium/Low 3. **Impact**: What could an attacker do? 4. **Remediation**: How to fix it? (specific code changes) 5. **Verification**: How to verify the fix? #### Example Remediation Report **Finding 1: Passwords Logged in Production** **Vulnerability**: ```javascript // File: /src/auth/login.js:45 console.log('User login:', username, password) ``` **Risk**: CRITICAL **Impact**: - User passwords exposed in logs - Attacker with access to logs can compromise accounts - Complete security bypass **Remediation**: ```javascript // Remove the log entirely - console.log('User login:', username, password) // Or if debugging is needed, never log passwords + if (process.env.NODE_ENV === 'development') { + console.log('Login attempt:', username) + } ``` **Verification**: 1. Search codebase: `grep -r "console.log.*password" src/` 2. Verify no matches found 3. Test production build: No passwords in console 4. Code review before deployment --- **Finding 2: SQL Injection Vulnerability** **Vulnerability**: ```javascript // File: /src/db/users.js:78 const query = `SELECT * FROM users WHERE email = '${email}'` db.exec(query) ``` **Risk**: CRITICAL **Impact**: - Attacker can bypass authentication - Attacker can access all user data - Attacker can modify/delete database - Complete database compromise **Remediation**: ```javascript // Use parameterized queries - const query = `SELECT * FROM users WHERE email = '${email}'` - db.exec(query) + const query = 'SELECT * FROM users WHERE email = ?' + db.prepare(query).get(email) ``` **Verification**: 1. Search for string interpolation in SQL: `grep -r "SELECT.*\${" src/` 2. Verify all queries use parameterization 3. Test: Try `' OR '1'='1` as input, verify it's treated as literal 4. Security testing with SQLMap (if applicable) --- #### Remediation Priorities **Critical (Fix immediately)**: 1. Hardcoded secrets/keys 2. Weak/broken cryptography 3. SQL/Command injection 4.
