Using Splunk to Detect DNS Tunneling
- Steve Jaworski
- Tuesday, December 13th, 7:15pm - 7:55pm
DNS tunneling is a method to bypass security controls and exfiltrate data from a targeted organization. Choose any endpoint on your organization's network and perform a lookup to a public site, if it resolves with the siteās IP address, that endpoint is susceptible to DNS Tunneling. It is not possible to block all DNS tunnels. Logging all DNS transactions is necessary to detect the occurrence of DNS Tunnels. Using Splunk can help ingest the large volume of log data and mine the information to determine what malicious actors may be using DNS tunneling techniques on target organizations networks.
