DNS security

DNS Security refers to the measures and protocols put in place to protect the Domain Name System (DNS) from various cyber threats and attacks. The DNS is a crucial component of the internet infrastructure, translating domain names into IP addresses and facilitating the smooth functioning of internet communication.

An important component of DNS security is DNSSEC (Domain Name System Security Extensions), which adds cryptographic signatures to DNS records to ensure their authenticity and integrity. It also includes measures to prevent DNS cache poisoning, DDoS attacks, and other malicious activities that can disrupt the DNS resolution process.

DNS security is essential for maintaining the integrity and reliability of Internet communication. Without proper DNS security measures in place, cybercriminals can intercept DNS queries, redirect users to malicious websites, or launch attacks that disrupt internet services.
