Whitelist/blacklist // 2. Argument sanitization // 3. Path traversal prevention // 4. Injection attack prevention ``` #### Whitelisted Commands by Security Level **STRICT Mode:** ```json { "allowedCommands": ["node", "npm", "git", "echo", "cat", "ls", "pwd"] } ``` **DEVELOPMENT Mode:** ```json { "allowedCommands": [ "node", "npm", "yarn", "pnpm", "bun", "git", "cargo", "rustc", "python", "pip", "echo", "cat", "ls", "pwd", "find", "grep", "curl", "wget", "docker", "kubectl" ] } ``` #### Command Learning System MOIDVK can learn new commands with explicit user consent: ```bash # When a new command is encountered $ moidvk secure-bash "newcommand --flag" 🔍 Unknown command detected: newcommand 📋 Command: newcommand --flag 🛡️ Security Level: DEVELOPMENT Would you like to: 1. Allow once 2. Allow and remember (add to whitelist) 3. Deny 4. Deny and block (add to blacklist) Choice: 2 ✅ Command learned and executed safely ``` ### Sandboxing Commands are executed in a controlled environment: ```json { "sandbox": { "workingDirectory": "./", "allowedPaths": ["./src", "./tests", "./docs"], "deniedPaths": ["/etc", "/usr", "/var", "/root"], "environmentVariables": "filtered", "networkAccess": "restricted", "timeout": 60000 } } ``` ## 📁 File Access Security ### Path Validation All file operations are validated against security policies: ```javascript // Path validation example const validator = new SecurityValidator(); // Prevents path traversal attacks validator.validatePath('../../../etc/passwd'); // ❌ Blocked validator.validatePath('./src/app.js'); // ✅ Allowed validator.validatePath('/tmp/malicious'); // ❌ Blocked ``` ### File Access Policies ```json { "fileAccess": { "allowedPaths": [ "./src/**", "./tests/**", "./docs/**", "./package.json", "./tsconfig.json", "./.moidvk.json" ], "deniedPaths": ["/etc/**", "/usr/**", "/var/**", "/root/**", "~/.ssh/**", "~/.aws/**"], "maxFileSize": "10MB", "allowSymlinks": false, "allowHiddenFiles": false } } ``` ### File Content Sanitization Sensitive content is automatically detected and sanitized: ```javascript // Sensitive patterns automatically redacted const sensitivePatterns = [ /password\s*[:=]\s*["']?([^"'\s]+)/gi, /api[_-]?key\s*[:=]\s*["']?([^"'\s]+)/gi, /secret\s*[:=]\s*["']?([^"'\s]+)/gi, /token\s*[:=]\s*["']?([^"'\s]+)/gi, /private[_-]?key\s*[:=]\s*["']?([^"'\s]+)/gi, ]; // Example output sanitization // Before: const apiKey = "sk-1234567890abcdef"; // After: const apiKey = "[REDACTED]"; ``` ## 🔐 Data Privacy & Sanitization ### Privacy Modes #### Standard Privacy Mode ```json { "privacy": { "sanitizeSecrets": true, "sanitizePersonalInfo": true, "sanitizeFilePaths": false, "logLevel": "info" } } ``` #### Enhanced Privacy Mode ```json { "privacy": { "sanitizeSecrets": true, "sanitizePersonalInfo": true, "sanitizeFilePaths": true, "sanitizeContent": true, "anonymizeData": true, "logLevel": "error" } } ``` ### Data Sanitization Examples ```javascript // Input sanitization const input = ` const config = { apiKey: "sk-1234567890abcdef", password: "mySecretPassword123", email: "user@company.com", filePath: "/home/user/project/src/app.js" }; `; // Sanitized output (Enhanced Privacy Mode) const sanitized = ` const config = { apiKey: "[REDACTED]", password: "[REDACTED]", email: "[EMAIL_REDACTED]", filePath: "[PATH_REDACTED]/app.js" }; `; ``` ### Consent Management MOIDVK implements explicit consent for data sharing: ```bash # Snippet extraction with consent $ moidvk extract-snippet --file src/app.js --lines 10-20 🔒 Data Sharing Request 📄 File: src/app.js (lines 10-20) 🔍 Content: 150 characters 🛡️ Privacy: Enhanced mode enabled The following data will be processed: - Code snippet (10 lines) - File metadata - No personal information detected Do you consent to processing this data? [y/N]: y ✅ Consent granted, processing snippet... ``` ## 🔍 Vulnerability Scanning ### Dependency Scanning MOIDVK provides comprehensive dependency vulnerability scanning: ```bash # Scan for security vulnerabilities moidvk scan-security-vulnerabilities # Filter by severity moidvk scan-security-vulnerabilities --severity high # Production dependencies only moidvk scan-security-vulnerabilities --production # Detailed report moidvk scan-security-vulnerabilities --format detailed ``` ### Vulnerability Database MOIDVK uses multiple vulnerability databases: - **NPM Audit** - Node.js package vulnerabilities - **PyUp Safety** - Python package vulnerabilities - **RustSec** - Rust crate vulnerabilities - **GitHub Advisory** - Cross-platform vulnerabilities - **CVE Database** - Common Vulnerabilities and Exposures ### Vulnerability Reporting ```json { "vulnerability": { "id": "GHSA-xxxx-xxxx-xxxx", "package": "lodash", "version": "4.17.15", "severity": "high", "title": "Prototype Pollution", "description": "Lodash versions prior to 4.17.19 are vulnerable to...", "fixedIn": "4.17.19", "references": ["https://github.com/advisories/GHSA-xxxx-xxxx-xxxx"], "remediation": { "type": "update", "command": "npm update lodash" } } } ``` ## 🛡️ Code Safety Analysis ### NASA JPL Power of 10 Rules MOIDVK enforces NASA JPL's Power of 10 safety-critical programming rules: ```bash # Check safety rules moidvk check-safety-rules --file src/critical.js # Example violations detected: # ❌ Rule 1: Avoid complex flow constructs (goto, setjmp, recursion) # ❌ Rule 2: All loops must have fixed bounds # ❌ Rule 3: Avoid heap memory allocation after initialization # ❌ Rule 4: Restrict functions to a single printed page # ❌ Rule 5: Use a minimum of two runtime assertions per function ``` ### Safety Rule Examples #### Rule 1: Avoid Complex Flow Constructs ```javascript // ❌ Unsafe: Unbounded recursion function factorial(n) { return n <= 1 ? 1 : n * factorial(n - 1); } // ✅ Safe: Iterative approach with bounds function factorial(n) { if (n < 0 || n > 20) throw new Error('Invalid input'); let result = 1; for (let i = 2; i <= n; i++) { result *= i; } return result; } ``` #### Rule 2: Fixed Loop Bounds ```javascript // ❌ Unsafe: Unbounded loop while (condition) { // potentially infinite loop } // ✅ Safe: Bounded loop for (let i = 0; i < MAX_ITERATIONS && condition; i++) { // bounded iteration } ``` #### Rule 5: Runtime Assertions ```javascript // ✅ Safe: Function with assertions function divide(a, b) { assert(typeof a === 'number', 'First argument must be number'); assert(typeof b === 'number', 'Second argument must be number'); assert(b !== 0, 'Division by zero not allowed'); const result = a / b; assert(isFinite(result), 'Result must be finite'); return result; } ``` ### Language-Specific Safety #### Rust Safety Analysis ```bash # Rust memory safety check moidvk rust-safety-checker --file src/lib.rs # Checks for: # - Unsafe blocks # - Memory leaks # - Data races # - Buffer overflows # - Use after free ``` #### Python Security Analysis ```bash # Python security scan moidvk python-security-scanner --file src/app.py # Checks for: # - SQL injection vulnerabilities # - Command injection # - Hardcoded secrets # - Insecure random number generation # - Unsafe deserialization ``` ## 🔧 Secure Development Practices ### Secure Coding Guidelines #### Input Validation ```javascript // Always validate inputs function processUserInput(input) { // Validate type if (typeof input !== 'string') { throw new Error('Input must be string'); } // Validate length if (input.length > MAX_INPUT_LENGTH) { throw new Error('Input too long'); } // Sanitize content const sanitized = input.replace(/[<>'"&]/g, ''); return sanitized; } ``` #### Error Handling ```javascript // Secure error handling try { riskyOperation(); } catch (error) { // Log detailed error internally logger.error('Operation failed', { error, context }); // Return generic error to user throw new Error('Operation failed'); } ``` #### Secret Management ```javascript // ❌ Never hardcode secrets const apiKey = 'sk-1234567890abcdef'; // ✅ Use environment variables const apiKey = process.env.API_KEY; if (!apiKey) { throw new Error('API_KEY environment variable required'); } ``` ### Security Testing #### Automated Security Testing ```bash # Comprehensive security test suite moidvk security-test-suite # Individual security tests moidvk test-input-validation moidvk test-command-injection moidvk test-path-traversal moidvk test-xss-prevention ``` #### Security Test Examples ```javascript // Security test example describe('Input Validation Security', () => { test('prevents path traversal attacks', () => { const maliciousPath = '../../../etc/passwd'; expect(() => validatePath(maliciousPath)).toThrow(); }); test('sanitizes SQL injection attempts', () => { const maliciousInput = "'; DROP TABLE users; --"; const sanitized = sanitizeInput(maliciousInput); expect(sanitized).not.toContain('DROP TABLE'); }); }); ``` ##
