DNSSEC (Domain Name System Security Extensions) is the name given to security extensions to the DNS (Domain Name System) protocol conceived to protect and authenticate DNS traffic.
These extensions validate the data through digital signatures, making use of asymmetric cryptology technology to ensure the authenticity and integrity of information exchanged between DNS servers and between these and the user's applications.
- Suppressing the DNS protocol's fragilities;
- Preventing man-in-the middle and cache poisoning type attacks;
- Reducing the risk of information manipulation;
- Reinforcing the system's reliability.
Security threats and awareness of this have been a prime concern of the entities responsible for this matter and so specialists worldwide are concerned with searching for solutions that ensure a safer service and network environment.
