DDoSellenállás

DDoSellenállás refers to the ability of a system, network, or service to withstand and continue operating during a distributed denial-of-service (DDoS) attack. DDoS attacks aim to overwhelm a target with a flood of malicious traffic originating from multiple compromised sources, making it unavailable to legitimate users.

Achieving DDoSellenállás involves a multi-layered approach. Network infrastructure plays a crucial role, with firewalls, intrusion prevention systems, and traffic scrubbing centers designed to detect and filter out malicious traffic. Load balancing distributes incoming requests across multiple servers, preventing any single server from becoming a bottleneck. Content delivery networks (CDNs) can also help by caching content closer to users, reducing the load on the origin server and absorbing some of the attack traffic.

Application-level defenses are equally important. Secure coding practices, input validation, and rate limiting can prevent attackers from exploiting vulnerabilities or overwhelming application resources. Web application firewalls (WAFs) can identify and block malicious requests targeting specific web applications.

Monitoring and incident response are vital components of DDoSellenállás. Continuous monitoring of network traffic and system performance allows for early detection of an attack. A well-defined incident response plan ensures that security teams can quickly identify the source of the attack, implement mitigation strategies, and restore normal operations with minimal disruption. This proactive and reactive combination of measures strengthens a system's resilience against DDoS threats.
