- Audit and secure open DNS resolvers within your network perimeter Open resolvers are prime targets for reflection and amplification tactics.
- Deploy automated cloud-based DDoS mitigation with rate-limiting rules On-premise appliances often fail when subjected to terabit-scale volumetric floods.
- Disable or restrict CLDAP services on public-facing interfaces CLDAP is frequently exploited for high-factor amplification attacks.
- Establish an emergency response plan for state-sponsored threat campaigns Geopolitical friction points correlate heavily with targeted infrastructure disruption.
