Abstract
Companies without controlled doors cannot ensure the security and safety of their employees, nor can they prevent piracy and theft. Networks without controlled access cannot guarantee the security or privacy of stored data, nor can they keep network resources from being exploited by hackers. This study adopts several different firewall programs and uses Windows 2000 Server as the platform to test, and ultimately compare in detail, two different facets of each program, functionality and performance. Network security is always the most important issue of the company. From this study, recommendations will be provided through the testing of the firewall programs. When a company starts to use a firewall or other security measures, the performance of the network will be reduced. Trade-offs between security of the network and ease of access must be resolved. However, the solution to the negative aspects of firewalls is another issue to be dealt with in the future.
