Network security can be described as the effort to create a secure computing platform, designed so that agents (users or programs) cannot perform actions that they are not allowed to perform, but can perform the actions that they are allowed to. Network Security systems insure the integrity of the system by protecting from hackers trying to get into the system and by restricting access within the system to individuals specific needs. http://presentationslive.blogspot.com/
