How can ACLs be combined with other DDoS mitigation techniques for a more robust defense?

ACLs are most effective when combined with other DDoS mitigation techniques. For example, combining ACLs with rate limiting can prevent attackers from overwhelming the network even if they manage to bypass the initial ACL filters. Integrating ACLs with traffic scrubbing services allows for the removal of malicious traffic that ACLs might miss. This layered approach creates a more robust defense against a wider range of DDoS attacks. It's about creating multiple layers of defense to increase resilience.
