An introduction to DNSSEC

In the previous blog, we discussed various DNS vulnerabilities such as Cache Poisoning, Client Flooding, Information Disclosure attacks, Vulnerability in sharing a nameserver and DDos in DNS. DNSSEC provides answers to all except DDoS attacks. DNSSEC is not the abbreviation for DNS security but a set of resource records (such as A record, MX record) which can seamlessly integrate with our existing DNS infrastructure.
