Description
DNS port - 53 is used to query Domain Names to IP address. Allowing inbound traffic from all external IP addresses to DNS port can be vulnerable to DNS Hijacking, Cache Poisoning, and DNS Tunnelling attack. It is a best practice to restrict access from known public DNS server to destination port 53.
