Usage

Smart Usage Notes

• Repurposing: EtchDNS can be adapted for use in threat intelligence gathering by analyzing DNS query patterns to identify potential malicious domains.
• Chaining: Combine EtchDNS with a SIEM tool to enhance threat detection by correlating DNS query logs with other network activity logs for comprehensive threat analysis.
• Evasion/Detection: Attackers might bypass EtchDNS by using encrypted DNS over HTTPS (DoH) to conceal malicious queries. Implementing deep packet inspection could help detect such attempts.
• Data Fusion: Integrate EtchDNS output with threat intelligence platforms to enrich DNS query data with contextual threat indicators, enhancing the detection of suspicious activities.
• Automation: Develop automated scripts to dynamically update DNS filtering rules in EtchDNS based on real-time threat intelligence feeds, improving SOC response times to emerging threats.
