DNSSEC is an important security standard designed to protect the integrity of DNS (Domain Name System) data. The DNS is responsible for translating human-readable domain names (e.g. www.example.com) into IP addresses that computers can understand. However, the traditional DNS is vulnerable to several types of attacks, such as cache poisoning or man-in-the-middle attacks. This is where DNSSEC comes in.

What is DNSSEC?

DNSSEC adds an extra layer of security to the DNS by validating DNS responses using cryptographic signatures. It ensures that the information received from a DNS server has not been tampered with, guaranteeing the authenticity and integrity of the data.

Challenges and Limitations

While DNSSEC significantly improves DNS security, it does have some challenges and limitations:

Despite these challenges, DNSSEC is a critical security measure to protect against DNS-based attacks, and its adoption is highly recommended.
