Our computer are machines that are incpable of being used as a standalone system hence has become a creature comfort of being always connected to the internet at all times

If the connection to the internet not only allows us to do better and more things but also impacts our performance by makint th esytem at play vulnerable than the entire idea of the project is lost in the grand scheme of things

Hence our project aims to setup a simple DNS verification filtering and suspeciosus connection request handler that makes us safer on the internet

The objective of the paper is to fight dns tunnelling through suggestions.

To Bypass Firewalls with DNS Tunnelling which includes Defence Evasion, Exfiltration and Command & Control (Making , Analysing, Bypassing and Protecting a Firewall).
