Nowadays, DNS has become vital for the operation of the Internet and of any private network of a certain size. This protocol might be one of the oldest, but it is also one of the more sensitive. Security problems have been ignored for too long. It is now important to master the principles of this protocol as well as all its implications on security.


Goals

After this course, attendants will be able to master the installation and configuration of a DNS server as well as its strengthening from a security standpoint.
