What is DDoS?
An attack that overwhelms a target with traffic from multiple sources.
Detailed Explanation
DDoS attacks flood a server, service, or network with more traffic than it can handle, making it unavailable to legitimate users. Attackers typically use botnets (networks of compromised computers) to generate massive amounts of traffic. Common types include SYN floods, UDP floods, and application-layer attacks. Mitigation involves traffic filtering, rate limiting, and using CDN services.
Examples
- •SYN flood overwhelming web server with connection requests
- •DNS amplification attacks using open DNS resolvers
- •Application-layer attacks targeting specific URLs or APIs
