5 Ways to Protect your DNS Server against Hacker Attacks

Posted by B. Hale

In the present era of strong surveillance and presence of large chunks of data, many cryptographic algorithms are being developed in order to maintain privacy and security. These algorithms, when cracked by the hackers, makes every data to being disclosed to the outer world. In order to ensure protection, researchers have been working continuously to improve and devise better versions of algorithms.

Have a look at the video below and get an idea on how to fight with threats involving your DNS:

Each and every kind of data is relevant in this context and they are stored on our servers. So, to protect the DNS server against innumerable hacker attacks, several ways can be formulated, such as:

1. The first initiative that should be taken in order to protect data is to understand clearly what are we trying to achieve here. So, we need to understand that DNS was not developed with security. But, it has a large database containing domain names, IP addresses, and computer names, etc. That is why we should make it a point not to let the hijacker compromise our security point, that is recommended by www.bluecatnetworks.com.

2. Then, you need to formulate a policy for security, stating the guidelines as to what is to be accessed by the clients, what is the confidential data and what resources are to be allocated to achieve the level of security desired.

3. Further, one can design a third DNS server to act as a master server. The IP address of the master server should not be made public and should be utilized only to communicate with the other two front-faced servers. The requisite updates are to be transferred via a secure network.

4. At this stage, one is required to be decisive regarding the level of firewalls being used for the security. The extent and the current hacking situation should be kept in mind in order to take a decision.

5. The entries on the DNS should be devised with different access controls for different users as per the required authority. There are two types of entries that are in consideration here, that is, registry entries and file system entries. DNSSEC, that is, the DNS security extensions are required to be incorporated in the system to block an attack on front-facing servers.
