Hardening Application Security

Application security measures prevent exploitation of software vulnerabilities during DDoS attacks. Implement input validation to prevent injection attacks that might amplify DDoS impact. Validate all user inputs, sanitize data, and use parameterized queries. These measures prevent attackers from using your application against itself.

Session management hardening prevents resource exhaustion attacks. Implement session timeouts, limit concurrent sessions per user, and use efficient session storage. Configure session cookies with appropriate security flags. These measures prevent attackers from exhausting session resources.

API security prevents abuse of programmatic interfaces. Implement authentication for all API endpoints and use rate limiting to prevent abuse. Configure different limits for authenticated and anonymous users. Monitor API usage patterns to identify potential attacks early.

Caching strategies reduce backend load during attacks. Implement aggressive caching for static content and carefully designed caching for dynamic content. Use cache headers effectively to offload repeat requests. Configure cache invalidation carefully to maintain content freshness while maximizing protection.
