Threat Model & Mitigations
Comprehensive analysis of security threats and our mitigation strategies
| Threat | Description | Mitigation | Severity |
|---|---|---|---|
| Cross-Site Request Forgery (CSRF) | Malicious websites performing unauthorized actions | CSRF tokens and SameSite cookie attributes | High |
| Cross-Site Scripting (XSS) | Injection of malicious scripts into web pages | Input sanitization and Content Security Policy | High |
| Man-in-the-Middle (MITM) | Interception of communications between client and server | TLS encryption and certificate pinning | High |
| API Key Compromise | Unauthorized access through compromised API keys | Key rotation, scoping, and monitoring | Medium |
| Data Breach | Unauthorized access to sensitive user data | Encryption, access controls, and audit logging | High |
| Denial of Service (DoS) | Overwhelming system resources to cause unavailability | Rate limiting, load balancing, and DDoS protection | Medium |
Security Best Practices
Guidelines for implementing secure webMCP applications
API Security
Use HTTPS Everywhere
Always use HTTPS for all API communications
Implement Rate Limiting
Prevent abuse with configurable rate limits
Validate All Inputs
Sanitize and validate all user inputs
Authentication
Strong JWT Secrets
Use cryptographically secure secrets for JWT signing
Token Expiration
Set appropriate token expiration times
Secure Token Storage
Store tokens securely on client side
Data Protection
Encrypt Sensitive Data
Encrypt PII and sensitive form data
Secure Key Management
Implement proper key rotation and storage
Data Minimization
Only collect and process necessary data
Security Configuration Examples
Practical examples for implementing security features
Basic Security Configuration
Enable core security features
import { WebMCPProcessor } from '@webmcp/core';
const processor = new WebMCPProcessor({
security: {
// Enable CSRF protection
enableCSRF: true,
csrfTokenExpiry: 3600, // 1 hour
// JWT configuration
jwt: {
secret: process.env.JWT_SECRET,
expiresIn: '1h',
scopes: ['webmcp:read', 'webmcp:write']
},
// Data encryption
encryption: {
method: 'jwe',
algorithm: 'A256GCM',
keyRotationInterval: 86400 // 24 hours
},
// Rate limiting
rateLimit: {
windowMs: 60000, // 1 minute
maxRequests: 100,
skipSuccessfulRequests: false
}
}
});Advanced Security Setup
Production-ready security configuration
const securityConfig = {
// HTTPS enforcement
httpsOnly: true,
hsts: {
maxAge: 31536000, // 1 year
includeSubDomains: true,
preload: true
},
// Content Security Policy
csp: {
directives: {
defaultSrc: ["'self'"],
scriptSrc: ["'self'", "'unsafe-inline'"],
styleSrc: ["'self'", "'unsafe-inline'"],
imgSrc: ["'self'", "data:", "https:"]
}
},
// Security headers
headers: {
'X-Frame-Options': 'DENY',
'X-Content-Type-Options': 'nosniff',
'X-XSS-Protection': '1; mode=block',
'Referrer-Policy': 'strict-origin-when-cross-origin'
},
// Audit logging
audit: {
enabled: true,
logLevel: 'info',
sensitiveFields: ['password', 'ssn', 'creditCard'],
retention: 90 // days
}
};
const processor = new WebMCPProcessor({ security: securityConfig });Secure Your Implementation
