DNSSEC: Everything you need to know

The concept of DNSSEC

The collection of security extensions known as DNSSEC gives DNS authentication and data integrity.

The Internet Engineering Task Force (IETF) developed it in the 1990s. Its principal objective is to offer an authentication mechanism that uses digital signatures based on open cryptography to demonstrate the data’s origin. With a private key, the data owner can certify the security of DNS data (DNS records). Each recursive server can authenticate the source of the data by comparing it to the public key.

The root server is at the top of the trust chain, which extends down to the specific hostname. Except for the root zone, which has nothing above it, each zone is signed by the one above it.

The recursive server will drop data and try again if, for any reason, it cannot authenticate it. Be safe rather than sorry.

Definition of DNS attacks

What is the definition of DNS attacks? The term refers to a type of cyber attack in which malicious hackers target an organization’s DNS servers, which hold domain names that the hackers seek. They can then carry out the assaults listed below once they obtain those domain names. In addition, bad actors can potentially check for vulnerabilities in a system to exploit.

Any attack against the availability or stability of a network’s DNS service is referred to as a DNS attack. DNS assaults include cache poisoning and other attacks that use DNS as a method as part of a larger attack strategy.
