Mitigation Strategy Decision Trees

Effective response requires choosing appropriate mitigation strategies based on attack characteristics. Volumetric attacks overwhelming bandwidth demand different responses than application-layer attacks exhausting server resources. Decision trees guide responders through strategy selection based on observed attack patterns.

For volumetric attacks, prioritize upstream mitigation to preserve bandwidth. Activate cloud-based scrubbing services to filter traffic before it reaches your network. Implement null routing for expendable services to protect critical infrastructure. Work with ISPs on remote triggered black holes for overwhelming attacks. Choose strategies that stop traffic as close to sources as possible.

Application-layer attacks require more nuanced responses. Enable web application firewalls with aggressive rule sets. Implement CAPTCHA challenges to verify human users. Deploy rate limiting focused on resource-intensive operations. Use behavioral analysis to identify and block automated attack tools. Balance security with user experience to maintain service usability.

Multi-vector attacks demand layered responses addressing each vector. Start with the most damaging vector while preparing defenses for others. Coordinate multiple mitigation techniques to avoid conflicts. Monitor effectiveness continuously as attackers shift tactics. Maintain flexibility to adjust strategies as attacks evolve.
