DNS as Facilitator in Cyber Security

The first DNS persona in this 3-part series, DNS as Facilitator is the naive resolver in helping malware spread throughout your networks.

Key Takeaways

DNS in the facilitator role acts as a naive resolver that uncritically answers queries, enabling malicious domains to be resolved.
Malware leverages DNS facilitators to locate command-and-control servers and exfiltration endpoints across the network.
Lack of policy enforcement or threat intelligence integration at the DNS layer allows these facilitator resolvers to aid malware propagation.
DNS traffic handled by facilitator resolvers often appears legitimate, making early-stage malware activity difficult to detect.
Understanding DNS as a facilitator persona is foundational for designing more secure DNS architectures in subsequent models.
