Episode notes
DNS Is A High-Value Attack Surface
- DNS remains a core network service and a frequent target for attackers exploiting misconfigurations or compromises.
- Rich Campagna says about 40% of organizations lack dedicated DNS security, making them attractive low-effort targets.
Centralize DNS Resolution For Full Coverage
- Ensure all DNS requests and responses pass through a centralized security mechanism for inspection.
- Use a single point of DNS resolution so all assets, wherever they are, are covered consistently.
Inspect Responses, Not Just Requests
- Scanning only DNS requests is insufficient because attackers also compromise DNS servers to serve malicious responses.
- Campagna emphasizes inspecting responses as well as requests to catch poisoned or compromised infrastructure.
