The implementation addresses security issue #92 by adding stricter rate limits, IP-based blocking, and progressive delay mechanisms to prevent brute-force attacks and abuse. + +## Features Implemented + +### 1. Sensitive Endpoint Rate Limit Guard + +A new guard (`SensitiveEndpointRateLimitGuard`) has been created specifically for protecting sensitive endpoints with enhanced security features: + +- **Stricter rate limits** compared to standard API endpoints +- **Progressive delay mechanism** that increases delay time with repeated violations +- **IP-based blocking** after exceeding rate limits +- **Automatic IP blocking** with configurable duration +- **Whitelist support** to bypass rate limiting for trusted IPs +- **Comprehensive rate limit headers** in responses + +**Location:** `src/security/guards/sensitive-endpoint-rate-limit.guard.ts` + +### 2. Enhanced Rate Limiting on Authentication Endpoints + +#### Password Reset Endpoints + +**POST /auth/forgot-password** +- Rate limit: 3 requests per 15 minutes +- Progressive delay enabled +- IP blocking after exceeding limit (30 minutes block) +- Key prefix: `password_reset` + +**PUT /auth/reset-password** +- Rate limit: 5 requests per 15 minutes +- Progressive delay enabled +- IP blocking after exceeding limit (1 hour block) +- Key prefix: `password_reset_confirm` + +#### Token Refresh Endpoint + +**POST /auth/refresh-token** +- Rate limit: 10 requests per minute +- No progressive delay (to avoid impacting legitimate use) +- No automatic IP blocking +- Key prefix: `token_refresh` + +### 3.

Each request is tracked with a timestamp in a Redis sorted set +2. Expired entries are automatically removed before checking limits +3. Current count is compared against the configured maximum +4. Rate limit information is returned in response headers + +### Progressive Delay Mechanism + +When enabled, the progressive delay mechanism: + +1. Calculates excess attempts beyond the rate limit +2. Applies a delay of `attempts * 1000ms` (capped at 10 seconds) +3. Forces attackers to slow down their attempts +4. Does not impact legitimate users within limits + +### IP Blocking Integration + +The guard integrates with the existing `IpBlockingService`: + +1. Checks if IP is blocked before processing request +2. Checks if IP is whitelisted (bypasses all rate limiting) +3. Records failed attempts for tracking +4. Automatically blocks IPs when `blockOnExceed` is enabled +5. Configurable block duration per endpoint + +### Rate Limit Headers + +All rate-limited responses include the following headers: + +- `X-RateLimit-Limit`: Maximum requests allowed in the window +- `X-RateLimit-Remaining`: Remaining requests in current window +- `X-RateLimit-Reset`: Unix timestamp when the limit resets +- `Retry-After`: Seconds to wait before retrying (when blocked) + +## Configuration + +### Decorator Usage + +Apply rate limiting to any endpoint using the `@SensitiveRateLimit` decorator: + +```typescript +@Post('sensitive-operation') +@UseGuards(SensitiveEndpointRateLimitGuard) +@SensitiveRateLimit({ + windowMs: 300000, // 5 minutes + maxRequests: 5, // 5 requests max + keyPrefix: 'custom_prefix', // Redis key prefix + enableProgressiveDelay: true, + blockOnExceed: true, + blockDurationMs: 1800000, // 30 minutes block +}) +async sensitiveOperation() { + // Your implementation +} +``` + +### Configuration Options + +| Option | Type | Description | Default | +|--------|------|-------------|---------| +| `windowMs` | number | Time window in milliseconds | 60000 (1 min) | +| `maxRequests` | number | Maximum requests in window | 5 | +| `keyPrefix` | string | Redis key prefix | 'sensitive' | +| `enableProgressiveDelay` | boolean | Enable progressive delays | true | +| `blockOnExceed` | boolean | Block IP after exceeding | false | +| `blockDurationMs` | number | Block duration in ms | 3600000 (1 hour) | + +## Rate Limit Key Generation + +The guard generates rate limit keys in the following priority order: + +1. **User ID** (if authenticated): `user:{userId}` +2. **Email** (from request body): `email:{email}` +3. **IP Address** (fallback): `ip:{ipAddress}` + +This ensures: +- Authenticated users are tracked by user ID +- Password reset/registration tracked by email +- Anonymous requests tracked by IP + +## IP Address Extraction + +The guard extracts client IP addresses from: + +1. `x-forwarded-for` header (first IP in chain) +2. `x-real-ip` header +3. `connection.remoteAddress` +4. `socket.remoteAddress` + +This ensures correct IP detection behind proxies and load balancers. + +## Security Considerations + +### Fail-Open Design + +The guard is designed to fail open (allow requests) when: +- Redis connection fails +- Rate limiting service throws an error +- IP blocking service is unavailable + +This prevents security features from causing service outages while logging errors for investigation. + +### Protection Against Enumeration + +Password reset endpoints return generic messages regardless of whether the email exists, preventing user enumeration attacks. + +### Distributed Rate Limiting + +Using Redis ensures rate limits work correctly across multiple application instances in a distributed deployment. + +## Testing + +### Unit Tests + +Comprehensive unit tests cover: +- Rate limit enforcement +- IP blocking integration +- Whitelist functionality +- Progressive delay mechanism +- Header generation +- Key generation strategies +- Fail-open behavior + +**Location:** `test/security/guards/sensitive-endpoint-rate-limit.guard.spec.ts` + +### Integration Tests + +End-to-end tests verify: +- Password reset rate limiting +- MFA endpoint rate limiting +- Token refresh rate limiting +- Rate limit header accuracy +- IP-based tracking +- Rate limit reset behavior + +**Location:** `test/auth/sensitive-endpoints-rate-limit.e2e-spec.ts` + +## Monitoring and Logging + +All rate limit violations are logged with: +- Severity: WARN +- IP address +- Rate limit key +- Endpoint path +- Timestamp + +IP blocking events are logged with: +- Severity: WARN +- IP address +- Reason for blocking +- Block duration +- Timestamp + +## Migration Notes + +### Backward Compatibility + +The implementation is fully backward compatible: +- Existing endpoints continue to work +- No database migrations required +- No breaking API changes +- Existing rate limiting infrastructure is reused + +### Deployment Considerations + +1.
