Reverse NS Lookup: Security Against DNS-Based Attacks

Given today’s threat landscape, known threats or those that get publicized are quite hard to protect against. However, risks that come from unknown sources are even harder to detect and block. Domain Name System (DNS)-based attacks fall into the second category for a variety of reasons, the topmost of which is that once domains are up and running, their owners put their security in the background.

There are ways to avoid becoming the next victim of a DNS-based attack, though. One of them is using a reliable reverse name server (NS) solution such as Reverse NS Lookup.

Efforts to fix DNS security issues take up time and resources, too, which could also lead to even greater financial losses.
