DNS and its security (DNSSEC) are critical topics for online businesses.
What is DNSSEC?
Domain Name System Security Extensions, or DNSSEC, is a group of security measures created to provide cryptographic authentication to DNS data. It checks and proves the integrity of DNS data so you can be sure they haven’t been altered.
Network experts commonly describe it as a chain of trust because it verifies every point in the process a DNS query follows.
