Domain Name System—translates human-readable domain names into IP addresses computers use.
The Domain Name System (DNS) is the internet's phone book, translating domain names (like example.com) into IP addresses computers use to communicate. DNS is essential infrastructure—if DNS fails, internet services become inaccessible. DNS is also a security control point—protective DNS services block access to known malicious domains, while DNS monitoring can detect threats. Secure DNS configuration and monitoring are important security considerations.
Why It Matters
The DSC Perspective:
DNS is critical infrastructure and a security opportunity. Protective DNS services block malicious domains. DNS monitoring can detect malware communication. Secure your DNS and consider it in your security strategy.
