DNSSEC stands for Domain Name System Security Extensions, and it is a technology used to protect information on the Domain Name System (DNS) which is used on IP networks. It provides authentication for the origin of the DNS data, helping to safeguard against attacks and protect data integrity.
The DNS turns domain names, or website names, into internet protocol (IP) addresses. These are unique identifiers that help computers around the world access the information quickly. DNS security adds a set of extensions for increased protection
These security extensions include:
A DNS helps point web traffic to the right destination. It is used by everyone, everywhere and all internet traffic flows through it. For this reason, it is a highly sensitive system which is exposed to many threats from cyber attackers that aim to take control of a DNS, to infect and extract all data from it.
Many modern enterprises are often vulnerable to DNS server security risks because they only use a couple of DNS servers. As a result, this may leave them incapable of protecting against volumetric attacks, whereby large amounts of traffic to a website may cause servers to crashpreventing users from finding the website.
Besides compromising the way a DNS works, a malicious attack can also aim to exploit security vulnerabilities on the server that runs the DNS services, extracting valuable data such as passwords, usernames and other personal information.
These represent serious issues for companies, and make DNS security a critical component to ensuring online security.
Without adequate DNSSEC, enterprises may be exposed to:
