DNS Sinkholing is a powerful feature in network security that offers several advantages:
* Forging DNS replies to known malicious domains: This technique redirects malicious domain queries to a designated IP address (sinkhole), effectively preventing the malware from communicating with its command and control servers, thereby neutralizing its threat.
* Working upstream from the internal DNS server: DNS Sinkholing can be implemented upstream, meaning it intercepts and manipulates DNS queries before they reach the internal DNS server. This preemptive action helps in blocking threats early in the DNS resolution process, providing an additional security layer (Palo Alto Networks) (Palo Alto Networks).
