1. Authentication & Authorization Audit

Prompt: Verify all authentication mechanisms are secure and properly implemented.

Process:

Auth Service Specific Checks

cd /home/administrator/projects/coppertone.tech/backend/functions/auth-service
grep -n "bcrypt\|jwt\|ethereum" main.go

Password Hashing:

# Find password hashing implementation
grep -A 10 "GenerateFromPassword\|CompareHashAndPassword" main.go

Check:

• Uses bcrypt (not MD5, SHA1, or plain)
• bcrypt cost is 10 or higher
• Passwords never logged or returned in responses
• Password comparison uses constant-time comparison (bcrypt.CompareHashAndPassword)

Example Secure Implementation:

// ✅ GOOD
passwordHash, err := bcrypt.GenerateFromPassword([]byte(password), bcrypt.DefaultCost)

// Check cost
const cost = 10 // Should be >= 10

JWT Token Security:

# Find JWT implementation
grep -A 20 "jwt.New\|jwt.Sign\|jwt.Parse" main.go

Check:

• JWT secret from environment variable (not hardcoded)
• JWT secret is at least 32 characters (preferably 64+)
• Token expiration time set (not indefinite)
• Signing algorithm is HS256, RS256, or ES256 (not "none")
• Claims include user ID, roles, and expiration
• Token validation on protected routes

Example Secure Implementation:

// ✅ GOOD - Secret from environment
jwtSecret := []byte(os.Getenv("JWT_SECRET"))
if len(jwtSecret) == 0 {
    log.Fatal("JWT_SECRET must be set")
}

// ✅ GOOD - Token with expiration
token := jwt.NewWithClaims(jwt.SigningMethodHS256, jwt.MapClaims{
    "user_id": user.ID,
    "exp":     time.Now().Add(24 * time.Hour).Unix(),
    "roles":   roles,
})

Blockchain Authentication:

# Find Ethereum signature verification
grep -A 15 "verifyEthereumSignature\|crypto.Ecrecover" main.go

Check:

• Uses official go-ethereum library
• Signature verification before authentication
• Address normalization (lowercase)
• Message signing prevents replay attacks
• Nonce or timestamp included in signed message

Acceptance Criteria:

• Passwords hashed with bcrypt cost >= 10
• JWT secret from environment, 64+ characters
• Token expiration implemented
• Ethereum signatures properly verified
• No authentication bypass vulnerabilities

Documentation Template:

RBAC (Role-Based Access Control) Audit

Prompt: Verify role-based access control is properly enforced.

Process:

# Find RBAC middleware
grep -A 20 "requireRole\|checkRole" backend/functions/*/main.go

What to Check:

Role Definition:

• Roles defined as ENUM in database or constants in code
• Valid roles: ADMIN, STAFF, CLIENT (or similar)
• No hardcoded role checks scattered throughout code
• Centralized role validation

Middleware Implementation:

// Example pattern to find:
func requireRole(handler http.HandlerFunc, allowedRoles ...string) http.HandlerFunc {
    return func(w http.ResponseWriter, r *http.Request) {
        // Extract user from context
        // Check if user has required role
        // Allow or deny access
    }
}

Check:

• Role verification happens in middleware (not in handlers)
• User roles extracted from JWT claims
• Default deny (if no role matches, deny access)
• All protected endpoints use requireRole middleware

Protected Endpoints:

# Find all protected routes
grep -n "http.HandleFunc\|http.Handle" backend/functions/*/main.go

For Each Endpoint, Verify:

• Public endpoints (register, login, healthz): No authentication needed
• Protected endpoints: Wrapped with authenticate() middleware
• Admin endpoints: Wrapped with requireRole("ADMIN")
• Client endpoints: Wrapped with requireRole("CLIENT", "STAFF", "ADMIN")

Example Secure Implementation:

// ✅ GOOD - Protected with RBAC
http.HandleFunc("/admin/users", authenticate(requireRole(handleAdminUsers, "ADMIN")))
http.HandleFunc("/projects", authenticate(requireRole(handleProjects, "CLIENT", "STAFF", "ADMIN")))

// ✅ GOOD - Public endpoint
http.HandleFunc("/register", handleRegister)
http.HandleFunc("/healthz", handleHealth)

Acceptance Criteria:

• All protected endpoints wrapped with authentication
• Admin endpoints require ADMIN role
• RBAC enforced via middleware (not scattered checks)
• Default deny policy

Documentation Template:

### RBAC Audit Results

**Services Audited:**
- auth-service: [NUMBER] endpoints
- work-management-service: [NUMBER] endpoints
- payment-service: [NUMBER] endpoints

**Endpoint Classification:**

Process:

# Find all HTTP handlers
grep -n "func handle" backend/functions/*/main.go

# For each handler, check for input validation

What to Validate:

Email Addresses:

• Format validation (regex or library)
• Length limits (max 255 characters)
• Normalization (lowercase)
• No SQL injection characters if used in queries

Passwords:

• Minimum length (recommend 8+ characters)
• Maximum length (prevent DOS, recommend 100)
• No whitespace-only passwords
• Complexity requirements (optional but recommended)

User Names:

• Length limits
• Allowed characters (alphanumeric, spaces, hyphens)
• XSS prevention (though Vue handles this)

Numeric IDs:

• Type validation (int, not string)
• Range validation (positive numbers)
• No negative IDs

Blockchain Addresses:

• Format validation (0x + 40 hex characters)
• Checksum validation
• Normalization (lowercase)

Amounts/Currency:

• Positive numbers only (or explicit negative handling)
• Maximum amount limits
• Decimal precision (2 digits for currency)

Example Validation Patterns:

// ✅ GOOD - Email validation
if req.Email == "" {
    http.Error(w, "Email is required", http.StatusBadRequest)
    return
}
if len(req.Email) > 255 {
    http.Error(w, "Email too long", http.StatusBadRequest)
    return
}

// ✅ GOOD - Password validation
if len(req.Password) < 8 {
    http.Error(w, "Password must be at least 8 characters", http.StatusBadRequest)
    return
}

// ✅ GOOD - Role validation
validRoles := map[string]bool{"ADMIN": true, "STAFF": true, "CLIENT": true}
if !validRoles[req.Role] {
    http.Error(w, "Invalid role", http.StatusBadRequest)
    return
}

// ✅ GOOD - Amount validation
if req.Amount <= 0 {
    http.Error(w, "Amount must be positive", http.StatusBadRequest)
    return
}

Acceptance Criteria:

• All user input validated before use
• Appropriate error messages (not exposing internal details)

3. Error Handling & Logging Audit

Prompt: Verify error handling doesn't leak sensitive information and logging is appropriate.

Process:

# Find error handling patterns
grep -n "http.Error\|log.Print\|fmt.Print" backend/functions/*/main.go

Error Handling Check:

Client-Facing Errors (http.Error):

• Generic messages (not exposing stack traces)
• No database error details exposed
• No file system paths exposed
• Appropriate status codes

Examples:

// ❌ BAD - Exposes internal details
http.Error(w, fmt.Sprintf("Database error: %v", err), 500)

// ✅ GOOD - Generic message
http.Error(w, "Internal server error", http.StatusInternalServerError)
log.Printf("Database error in handleUsers: %v", err) // Server-side logging

Server-Side Logging:

• Errors logged with context
• No passwords or secrets in logs
• No credit card numbers in logs
• User IDs included for tracking
• Timestamp included (automatic with log package)

Examples:

// ✅ GOOD - Detailed server-side logging
log.Printf("Failed to hash password for user %s: %v", email, err)
log.Printf("Database connection failed: %v", err)
log.Printf("JWT verification failed for token: %v", err)

// ❌ BAD - Logging sensitive data
log.Printf("User password: %s", password) // Never log passwords
log.Printf("JWT secret: %s", jwtSecret)   // Never log secrets

Authentication Logging:

• Successful logins logged (user ID, timestamp)
• Failed login attempts logged (email, IP, timestamp)
• Account creation logged
• Role changes logged

Acceptance Criteria:

• Client errors are generic and safe
• Server logs provide debugging details
• No sensitive data in logs
• Authentication events logged

Documentation Template:

### Error Handling & Logging Audit

4. CORS Configuration Audit

Prompt: Verify CORS is properly configured for security.

Process:

# Find CORS middleware
grep -A 15 "corsMiddleware\|CORS\|Access-Control" backend/functions/*/main.go

What to Check:

CORS Headers:

// Find this pattern:
w.Header().Set("Access-Control-Allow-Origin", "*")
w.Header().Set("Access-Control-Allow-Methods", "GET, POST, PUT, DELETE, OPTIONS")
w.Header().Set("Access-Control-Allow-Headers", "Content-Type, Authorization")

Development vs. Production:

• ⚠️ Access-Control-Allow-Origin: * - OK for development
• ✅ Access-Control-Allow-Origin: https://coppertone.tech - Required for production
• ✅ Environment-based configuration

Security Checks:

• Origin validation (not wildcard in production)
• Methods limited to necessary ones
• Headers limited to necessary ones (Content-Type, Authorization)
• Credentials handling if needed
• Preflight (OPTIONS) requests handled

Example Secure Implementation:

// ✅ GOOD - Environment-based CORS
func corsMiddleware(next http.Handler) http.Handler {
    return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
        allowedOrigin := os.Getenv("ALLOWED_ORIGIN")
        if allowedOrigin == "" {
            allowedOrigin = "*" // Development fallback
        }
        w.Header().Set("Access-Control-Allow-Origin", allowedOrigin)
        w.Header().Set("Access-Control-Allow-Methods", "GET, POST, PUT, DELETE, OPTIONS")
        w.Header().Set("Access-Control-Allow-Headers", "Content-Type, Authorization")

        if r.Method == "OPTIONS" {
            w.WriteHeader(http.StatusOK)
            return
        }

        next.ServeHTTP(w, r)
    })
}

Frontend Application Audit Process

Purpose

Audit Vue.js frontend for security, code quality, and best practices.

Files to Audit

• frontend/src/stores/*.ts (Pinia stores)
• frontend/src/views/*.vue (View components)
• frontend/src/components/*.vue (Reusable components)
• frontend/src/router/index.ts (Router configuration)
• frontend/src/App.vue (Root component)

---

1. XSS (Cross-Site Scripting) Prevention

Prompt: Verify the frontend properly escapes user input and doesn't inject raw HTML.

Process:

cd /home/administrator/projects/coppertone.tech/frontend

# Search for v-html (dangerous)
grep -rn "v-html" src/

# Search for innerHTML (dangerous)
grep -rn "innerHTML" src/

# Search for eval (dangerous)
grep -rn "eval(" src/

What to Check:

Vue Template Safety:

• No v-html usage (or justified and sanitized)
• All user input rendered with {{ }} (automatic escaping)
• No innerHTML manipulation
• No eval() or Function() usage

Safe Patterns:

<!-- ✅ GOOD - Automatic escaping -->
<div>{{ userInput }}</div>
<div :title="userInput"></div>

<!-- ❌ BAD - Raw HTML injection -->
<div v-html="userInput"></div>

<!-- ⚠️ CONDITIONAL - OK if sanitized -->
<div v-html="sanitizedHTML"></div>

Attribute Binding Safety:

<!-- ✅ GOOD - Vue handles escaping -->
<a :href="sanitizedUrl">Link</a>
<img :src="imageUrl" :alt="description">

<!-- ❌ BAD - Direct URL from user without validation -->
<a :href="userInput">Link</a>

JavaScript Context:

// ❌ BAD - Don't use eval
eval(userInput);
new Function(userInput)();

// ✅ GOOD - Use JSON.parse for data
const data = JSON.parse(userInput);

Acceptance Criteria:

• Zero usage of v-html (or all instances justified and sanitized)
• No eval() or Function() usage
• All user input properly escaped
• URL sanitization where applicable

Documentation Template:

### XSS Prevention Audit

**Files Scanned:** [NUMBER]
**Templates Checked:** [NUMBER]

**Dangerous Patterns Found:**
- v-html usage: [NUMBER] (should be 0 or justified)

2. Authentication State Management

Prompt: Audit authentication store for security best practices.

Process:

# Review auth store
cat frontend/src/stores/auth.ts

What to Check:

Token Storage:

• Where is token stored? (localStorage, sessionStorage, cookie)
• Token cleared on logout
• Token sent with API requests
• Token expiration handling

Security Considerations:

// Current implementation check:
// - localStorage: Vulnerable to XSS but OK for SPAs
// - sessionStorage: Cleared on tab close
// - httpOnly cookie: Most secure but requires CORS setup

Token Handling:

// ✅ GOOD - Token in Authorization header
headers: {
    'Authorization': `Bearer ${token}`
}

// ❌ BAD - Token in URL
fetch(`/api/data?token=${token}`)

Login/Logout Flow:

// ✅ GOOD - Clear token on logout
async logout() {
    this.user = null
    this.token = null
    this.isAuthenticated = false
    localStorage.removeItem('token')
    router.push('/login')
}

// Check for:
// - Token cleared from storage
// - User state reset
// - Redirect to login

Auto-Login/Session Restoration:

// Check for token validation on app load
// Should verify token is still valid, not just present
async checkAuth() {
    const token = localStorage.getItem('token')
    if (token) {
        // ✅ GOOD - Verify token with backend
        try {
            await this.fetchProfile()
        } catch {
            this.logout() // Clear invalid token
        }
    }
}

Acceptance Criteria:

• Token stored securely (localStorage acceptable)
• Token sent in Authorization header
• Token cleared on logout
• Invalid tokens handled gracefully
• No token in URLs

Documentation Template:

### Authentication State Audit

**Token Storage:**
- Location: [localStorage/sessionStorage/cookie]

Process:

cat frontend/src/router/index.ts

What to Check:

Route Definitions:

// Look for meta.requiresAuth
{
    path: '/dashboard',
    component: DashboardView,
    meta: { requiresAuth: true } // ✅ GOOD
}

{
    path: '/admin',
    component: AdminView,
    meta: { requiresAuth: true, role: 'ADMIN' } // ✅ BETTER
}

Navigation Guard:

// Should have global beforeEach guard
router.beforeEach((to, from, next) => {
    const authStore = useAuthStore()

    if (to.meta.requiresAuth && !authStore.isAuthenticated) {
        next('/login') // ✅ GOOD - Redirect to login
    } else {
        next()
    }
})

Check for Each Protected Route:

• /dashboard - Requires auth
• /projects - Requires auth
• /projects/:id - Requires auth
• /invoices - Requires auth
• /admin/* - Requires admin role

Public Routes:

• / (home) - Public
• /login - Public
• /register - Public
• /about - Public
• /contact - Public

Role-Based Routing:

// ✅ GOOD - Check roles
router.beforeEach((to, from, next) => {
    const authStore = useAuthStore()

    if (to.meta.requiresAuth) {
        if (!authStore.isAuthenticated) {
            next('/login')
            return
        }

        if (to.meta.role && !authStore.hasRole(to.meta.role)) {
            next('/unauthorized')
            return
        }
    }

    next()
})

Acceptance Criteria:

• All protected routes have requiresAuth: true

async fetchProjects() {
    try {
        const response = await fetch(`${API_URL}/projects`, {
            headers: { 'Authorization': `Bearer ${this.token}` }
        })

        if (!response.ok) {
            throw new Error('Failed to fetch projects')
        }

        this.projects = await response.json()
    } catch (err) {
        this.error = err.message // ✅ GOOD - User-friendly error
