DNS Threat Detection & Analysis

Astral provides dedicated detection capabilities focused on identifying threats and suspicious behavior related to DNS activity. DNS is a critical component of network communication and is frequently abused by attackers for reconnaissance, command-and-control, and data exfiltration. By analyzing DNS activity, Astral enables early detection of threats that may otherwise bypass traditional security controls.

DNS threat detection in Astral evaluates DNS request patterns, queried domains, resolution behavior, and relationships between clients and DNS servers. Abnormal request volumes, unusual query frequencies, and atypical domain resolution behavior are analyzed as potential indicators of malicious activity. This includes detection of patterns commonly associated with malware communication, automated tooling, or unauthorized external interactions.

Astral also identifies DNS activity linked to known or suspected malicious infrastructure. By correlating DNS queries with threat intelligence sources and internal telemetry, Astral can detect communication with suspicious or high-risk domains. This correlation enhances confidence in detections and supports rapid identification of compromised hosts.

In addition to detection, Astral provides analytical capabilities for DNS activity over time. Security teams can analyze DNS request trends, client behavior, and geographic distribution of resolved domains to uncover hidden threats and support investigation. These insights help identify command-and-control channels, tunneling behavior, and abnormal external dependencies.

All DNS-related detections and analyses are integrated into Astral’s unified security workflow. Identified threats are forwarded to Inopli’s Response and RPA capabilities, enabling investigation, containment, and automated mitigation actions. This ensures that DNS-based threats are addressed as part of a coordinated and end-to-end security operation.
