- Enhanced Secure Command Executor - Validates and sandboxes command execution
- Input Validator - Sanitizes and validates all inputs
- Trusted Tool Verifier - Ensures tool integrity and authenticity
- Rate Limiter - Prevents abuse and DoS attacks
- Error Handler - Secure error handling without information leakage
- JPL Assertions - NASA JPL Power of 10 safety rule enforcement
MOIDVK provides four security levels to balance security with development productivity:
- Use Case: Production environments, critical systems
- Features: Maximum security, minimal permissions
- Command Execution: Highly restricted whitelist
- File Access: Minimal required paths only
- Learning: Disabled
- Privacy: Maximum data sanitization

}MOIDVK's Enhanced Secure Command Executor provides multiple layers of protection:
// Example of command validation process
const secureExecutor = new EnhancedSecureCommandExecutor({
securityLevel: 'DEVELOPMENT',
enableLearning: true,
keepPrivate: true,
});
// Commands are validated against:
// 1. Whitelist/blacklist
// 2. Argument sanitization
// 3. Path traversal prevention
// 4. Injection attack preventionSTRICT Mode:
{
"allowedCommands": ["node", "npm", "git", "echo", "cat", "ls", "pwd"]
}DEVELOPMENT Mode:
{
"allowedCommands": [
"node",
"npm",
"yarn",
"pnpm",
"bun",
"git",
"cargo",
"rustc",
"python",
"pip",
"echo",
"cat",
"ls",
"pwd",
"find",
"grep",
"curl",
"wget",
"docker",
"kubectl"
]
}MOIDVK can learn new commands with explicit user consent:
# 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 safelyCommands are executed in a controlled environment:

"deniedPaths": ["/etc", "/usr", "/var", "/root"],
"environmentVariables": "filtered",
"networkAccess": "restricted",
"timeout": 60000
}
}All file operations are validated against security policies:
// 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{

"maxFileSize": "10MB",
"allowSymlinks": false,
"allowHiddenFiles": false
}
}Sensitive content is automatically detected and sanitized:
// Sensitive patterns automatically redacted
const sensitivePatterns = [
/password\s*[:=]\s*["']?([^"'\s]+)/gi,
/api[_-]?key\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]";{

}MOIDVK enforces NASA JPL's Power of 10 safety-critical programming rules:
# 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// ❌ Unsafe: Unbounded recursion

let result = 1;
for (let i = 2; i <= n; i++) {

}

}// ❌ Unsafe: Unbounded loop
while (condition) {
// potentially infinite loop
}
// ✅ Safe: Bounded loop
for (let i = 0; i < MAX_ITERATIONS && condition; i++) {
// bounded iteration
}// ✅ 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');
