Network and Firewall Administrators have been facing a battle to uphold the integrity and productivity of their networks. Some of the major issues they have found with these potentially dangerous applications (P2P, IM’s) are the potential to disclose corporate information (source code etc) in a non mediated forum, the misuse of company resources, legal issues, possible virus incursion and simply the fact that it is another (flavor of the month) type point of attack, potentially jeopardizing the entire network. This article will describe how in simple terms we can leverage a new feature of ISA Server 2004 to prevent these types of applications clogging our internet pipe and exposing our company/network to the above issues.
