Smart cooperative firewalls : An aid to a safer and secure cyber world

A Firewall is a necessity in the cyber world today. Cyber-attacks have become a guarantee for any large business or any network containing useful information. Firewalls can be very effective when intelligently designed and run for a single machine; however, they have an issue when they are part of an interconnected firewall network. Administrators are responsible for updating or changing each firewall individually, which has been shown to lead to many errors. In this paper we propose a solution: smart cooperative firewalls. Firewalls that can talk to each other, don't need to be manually updated, and therefore have faster and more accurate attack response procedures. Our proposal, named DSN (Distributed Secured Network), turns multiple, but separate, firewalls into a dynamic network of firewalls all working together to combat cyber-attacks.
