Security Intelligence

💡 DDoS Mitigation Approaches

Distributed denial of service attacks overwhelm infrastructure with traffic volume. Effective mitigation combines always-on traffic scrubbing, anycast network distribution, rate limiting, and the ability to quickly scale absorption capacity during attacks.

💡 Tor Exit Node Detection

Tor exit nodes are publicly listed but constantly rotating. While Tor serves essential privacy functions for journalists and activists, it is also used to anonymize attacks. Effective security policies differentiate between blocking and monitoring Tor traffic.
