Hide DNS server (BIND) version from others

DNS server is one of the most targeted application for attack, It’s always a good idea to hide your DNS server version information so that BAD guys cannot view the version and start the attack to this specific version of your DNS server (Bind).

To hide your version of bind, add the following value to named.conf in the options section section as follows:

options {
directory “/var/named”;
version “[SECURED]”;
};
