Advanced Security Rules

🔐 Authentication & Authorization

// ❌ Vulnerable - Hardcoded bypass
func bypassAuth() {
    if userID == "admin" {
        grantAccess() // Authentication bypass
    }
}

// ✅ Secure - Proper validation
func validateAuth(token string) bool {
    return validateJWT(token) && checkPermissions(token)
}

🍪 Session Management

// ❌ Vulnerable - Insecure session
func createSession(userID string) {
    session := &Session{
        UserID: userID,
        Expires: time.Now().Add(24 * time.Hour), // Too long
    }
}

// ✅ Secure - Proper session management
func createSecureSession(userID string) *Session {
    return &Session{
        UserID: userID,
        Expires: time.Now().Add(30 * time.Minute),
        Secure: true,
        HttpOnly: true,
    }
}

🌐 API Security

// ❌ Vulnerable - No rate limiting
func handleAPIRequest(req *http.Request) {
    processRequest(req) // No rate limiting
}

// ✅ Secure - Rate limited API
func handleSecureAPIRequest(req *http.Request) {
    if !checkRateLimit(req) {
        http.Error(w, "Rate limit exceeded", 429)
        return
    }
    processRequest(req)
}

🔗 GraphQL Security

// ❌ Vulnerable - Introspection enabled
func setupGraphQL() {
    schema := graphql.MustParseSchema(`
        type Query {
            users: [User!]!
        }
    `, &resolvers{})
}

// ✅ Secure - Introspection disabled
func setupSecureGraphQL() {
    schema := graphql.MustParseSchema(`
        type Query {
            users: [User!]!
        }
    `, &resolvers{})
    schema.DisableIntrospection()
}

🎫 JWT Security

// ❌ Vulnerable - Weak algorithm
func createJWT(claims map[string]interface{}) string {
    token := jwt.NewWithClaims(jwt.SigningMethodHS256, claims)
    return token.SignedString([]byte("weak-secret"))
}

// ✅ Secure - Strong algorithm and key
func createSecureJWT(claims map[string]interface{}) string {
    token := jwt.NewWithClaims(jwt.SigningMethodRS256, claims)
    return token.SignedString(privateKey)
}

🔌 WebSocket Security

// ❌ Vulnerable - No authentication
func handleWebSocket(w http.ResponseWriter, r *http.Request) {
    upgrader := websocket.Upgrader{
        CheckOrigin: func(r *http.Request) bool {
            return true // Accepts all origins
        },
    }
    conn, _ := upgrader.Upgrade(w, r, nil)
}

// ✅ Secure - Proper authentication
func handleSecureWebSocket(w http.ResponseWriter, r *http.Request) {
    if !validateToken(r) {
        http.Error(w, "Unauthorized", 401)
        return
    }
    upgrader := websocket.Upgrader{
        CheckOrigin: func(r *http.Request) bool {
            return validateOrigin(r.Header.Get("Origin"))
        },
    }
    conn, _ := upgrader.Upgrade(w, r, nil)
}

---

🏗️ Architecture Analysis

Layered Architecture Compliance

CodexSentinel analyzes your Go application's architecture to ensure proper layer separation:

// ❌ Violation - Direct layer call
package handler

func (h *Handler) GetUser(id string) {
    user := h.repo.GetUser(id) // Direct call to repository
}

// ✅ Compliant - Proper layer separation
package handler

func (h *Handler) GetUser(id string) {
    user := h.service.GetUser(id) // Service layer mediates
}

God Struct Detection

Identifies overly complex structs that violate single responsibility principle:

// ❌ God Struct - Too many responsibilities
type UserManager struct {
    // Authentication
    authService    *AuthService
    sessionManager *SessionManager

    // Business Logic
    userService    *UserService
    orderService   *OrderService

    // Data Access
    userRepo       *UserRepository
    orderRepo      *OrderRepository

    // Configuration
    config         *Config
    logger         *Logger
}

// ✅ Focused Structs - Single responsibility
type UserService struct {
    userRepo *UserRepository
    logger   *Logger
}

type AuthService struct {
    authRepo *AuthRepository
    config   *AuthConfig
}

📦 Dependency Analysis

Vulnerability Scanning

CodexSentinel integrates with multiple vulnerability databases:

# Scan dependencies for vulnerabilities
codex-cli scan . --deps

# Output example:
[HIGH] Vulnerable Dependency at go.mod:0
    Description: Module github.com/go-yaml/[email protected]+incompatible has vulnerability: GHSA-r88r-gmrh-7j83
    Remediation: Update to a fixed version or apply security patches

License Compliance

# Check license compliance
codex-cli scan . --deps

# Output example:
[INFO] License Analysis
    Module: github.com/gorilla/websocket
    License: BSD-2-Clause
    Status: ✅ Compliant

---

🔍 Advanced Analysis

Taint Analysis

CodexSentinel performs sophisticated taint analysis to track untrusted data:

// ❌ Taint flow detected
func handleUserInput(input string) {
    query := "SELECT * FROM users WHERE name = " + input // Tainted data
    db.Query(query) // Sink function
}

// ✅ Safe - No taint flow
func handleSecureInput(input string) {
    query := "SELECT * FROM users WHERE name = ?"
    db.Query(query, input) // Parameterized query
}

SSA (Static Single Assignment) Analysis

Advanced data flow analysis using SSA form:

// CodexSentinel analyzes SSA form to detect:
// - Variable reassignments
// - Data flow paths
// - Dead code elimination
// - Constant propagation

⚙️ Configuration

Custom Rules (YAML)

Create custom security rules in assets/rules/:

id: "custom.insecure.xss"
title: "Custom XSS Detection"
category: "security"
severity: "high"
pattern: "w.Write([]byte({{input}}))"
filters:
  - type: "param"
    sources: ["r.FormValue", "r.URL.Query"]
description: "Custom XSS vulnerability detection"
suggestion: "Use html.EscapeString() to sanitize input"
references:
  - "https://owasp.org/www-project-top-ten/"

Ignore File

Create .codexsentinel.ignore to suppress specific issues:

# Ignore specific files
testdata/vulnerable_example.go

# Ignore specific rules
SEC001
CUSTOM001

# Ignore by pattern
**/vendor/**
**/test/**

📚 Examples

Security Vulnerabilities

SQL Injection

// ❌ Vulnerable
query := "SELECT * FROM users WHERE id = " + userInput
db.Query(query)

// ✅ Secure
query := "SELECT * FROM users WHERE id = ?"
db.Query(query, userInput)

Command Injection

// ❌ Vulnerable
cmd := exec.Command("sh", "-c", userInput)
cmd.Run()

// ✅ Secure
cmd := exec.Command("echo", userInput)
cmd.Run()

XSS (Cross-Site Scripting)

// ❌ Vulnerable
w.Write([]byte(userInput))

// ✅ Secure
w.Write([]byte(html.EscapeString(userInput)))

Architecture Examples

Proper Layer Separation

// ✅ Good Architecture
package handler

type Handler struct {
    userService *service.UserService
}

func (h *Handler) GetUser(id string) {
    user := h.userService.GetUser(id)
    // Handler only handles HTTP concerns
}

package service

type UserService struct {
    userRepo *repository.UserRepository
}

func (s *UserService) GetUser(id string) *User {
    return s.userRepo.GetUser(id)
    // Service handles business logic
}
