DNS Security

In today’s world, DNS security has become a crucial element in maintaining a secure and consistent online experience. DNS security is the process of protecting DNS (domain name system) infrastructure from cyber attacks to ensure its quick and efficient functioning. As DNS was not initially designed with security in mind, it has several design limitations that make it vulnerable to various attacks. Since DNS plays a crucial role in most internet requests, it can be a prime target for cyber attacks.

DNS attacks often work in conjunction with other cyberattacks to distract security teams from the primary target. Organizations must be equipped to mitigate DNS attacks quickly to prevent them from becoming overwhelmed and unable to handle simultaneous attacks through other vectors. To achieve effective DNS security, several overlapping defenses must be employed, including setting up redundant DNS servers, applying security protocols like DNSSEC, and implementing strict DNS logging.

There are numerous ways that attackers can exploit DNS servers, some of which are more common than others. DNS spoofing, tunneling, and hijacking, along with phantom domain attack, random subdomain attack, and botnet-based CPE attack are some of the most commonly used methods, which sometimes result in the theft of personal information. Therefore, it is essential to employ DNS security measures to protect against these attacks and maintain a safe and reliable online environment.
