Explore the concept of the DNSSEC. This allows the ability to help secure DNS communcations by using cryptography to allow clients to validate a DNS server.
- [Instructor] Another feature you can use…to help secure DNS has been around for quite a while…at this point, but it's something called DNSSEC.…So DNSSEC, which actually stands for…The Domain Name System Security Extensions,…is pretty much just what it sounds like.…Security extensions on DNS.…This enables DNS zones and all records in the zone…to be signed cryptographically so that…client computers can validate the DNS response.…
DNS is often subject to various attacks,…such as spoofing, cash tampering, and things like that,…and DNSSEC can help protect against these types of threats…and provide a more secure DNS infrastructure.…
