Thwarted, the hacker then tries another route. This time the ''super user'' account is the target. When IT managers log on as a super user they gain access to anything on the system, including passwords, credit card data, or Web pages. But PitBull puts a guard on that account and won't grant access unless the correct password is used and the request is coming from a computer within the company. The hacker is frustrated.
Most security systems function like a lock on the front door.
Once through the door, every room is accessible. But PitBull is like having a lock on every door of the house. It isolates the Web site's servers and applications, making it impossible for the attacker to get at areas that hold sensitive information. For example, the hacker can reach the Web server from the Internet and see Web pages but can't manipulate data. The McGraw-Hill Companies Inc. All rights reserved.
