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.
There are different types of firewalls that you can use for your managed servers' needs: the network layer or packet filter, the application layer, the proxy and the network address translation. The network layer operates as a very low transmission control protocol and does not allow packets to pass through unless they will match the set of packets defined by the layer's rules. The application layer takes care of the applications of your server. They intercept all of the packets that enter or leave your server's applications.
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.
A hardware firewall, when installed to your server has a predefined set of rules that will decide whether the information your server receives should be forwarded as request or dropped by your server. This predefined set of rules entail the use of packet filtering, which analyzes the header of a packet to find out the source of the information received by your server and its destination.
It is important to take note of your managed servers' need. Using a firewall that could work hand in hand with your server is necessary if you want to block out any form of attack that could render your servers useless.
