Top 5 Emerging Vendors providing DNS Security

Before talking about the top 5 vendors providing DNS Security (Domain Name System Security), let us first fully understand what DNS Security does and if security is not implemented how can it be harmful.

What is DNS (Domain Name System)?

DNS (Domain Name System) is the most important part of Internet. When entering any website’s address (e.g. www.firecompass.com- easy to remember), the address is converted into machine readable numbers i.e. IP Address (e.g. 64.383.372.190 – not easy to remember). Thus, DNS converts the human-readable address into machine-readable IP Address. ICANN manages the DNS Root Servers.

Hackers found some weakness in DNS which can allow attackers to create a fake DNS records. These fake records can trick users to visit fake websites, downloading malicious files and software’s. Attacker can gain the control and redirect the domain name to another or fake domain.
