Domain Name System Security Extensions (DNSSEC) is a security feature that makes sure you are connecting to a legitimate website and not a fake one while attempting to access a page through its domain name. 

Here’s how it works. Every domain name has a digital signature which can tell if it is clean or is being used by hackers to victimize Web users. DNSSEC’s role is to prevent people from falling into the trap by first verifying the trustworthiness of the digital signature of the domain name that you enter in a browser. If it checks out, then you are assured of being on the right and safe location.
