Do I Need a Firewall for My Server?

By Kevin Abrahams


Are you aware that there are several ways to hack into your server? People have already devised many creative techniques to hack though a network such as remote login, macros, viruses, spams, application backdoors, OS bugs, session hijacking, source routing and redirect bombs. This means your server is vulnerable from thousands of Trojans and viruses that just float around the web and are just waiting for the right moment to strike at your servers. To ensure that your managed servers are not easily vulnerable against these methods, you need a firewall that will protect your network.

A hardware firewall is often acquired as a stand-alone product. Unlike the software firewall, the hardware firewall is a component that you can see or touch. It is a very important component of your network set-up and system because it is very effective even if there is no configuration and it provides protection on ever machine of your managed servers.

Hardware firewall is one of your best defenses against malicious people who wish to steal information from your servers. They stop these people from entering your network and gaining access to the important files in your server.

They block out all of the unwanted traffic from reaching your server which in turn, could prevent the spread of worms and Trojans in your server. The proxy on the other hand, responds to these packets. They make the tampering of information in an internal system very difficult. This could ensure that any misuse of your machines will not result to a security breach that other people can exploit. The network address translation hides the true address of your server. It could be a useful defense against the increasing network reconnaissance.
