The Threat Hunter’s New Weapon: DNS Data

Chief Cybersecurity Officer for Cyxtera, Chris Day talks about the evolution of cybersecurity and rise of the threat hunter role.

Key Takeaways

DNS data provides a rich, often underused telemetry source that can reveal indicators of compromise and attacker infrastructure earlier than traditional logs.
The evolution of cybersecurity from perimeter defense to proactive detection has elevated the importance of specialized threat hunter roles within security teams.
Threat hunters increasingly rely on DNS query and response patterns to identify anomalous behaviors such as domain generation algorithms, fast-flux networks, and command-and-control channels.
Integrating DNS data with other security tooling enables more accurate correlation, faster incident triage, and improved attribution of advanced threats.
Effective use of DNS analytics requires high-quality, comprehensive DNS logging and the ability to query and visualize this data at scale.
