Because of the many threats lurking in the Internet, it is vital for a wise businessman such as yourself to invest in products that could safeguard your managed servers from any unsuspecting attack. To ensure that your servers will always have maximum security, even without your supervision, it is necessary to enlist the help of a good firewall that could block malicious requests before they even reach your server.
A firewall is a software program or a hardware contraption that filter out all the Information that tries to gain access to your server. It utilizes a method called packet filtering, which checks the incoming packet and analyzes it to make sure it is not flagged before it forwards the request to your server.
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.
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. To ensure that your managed servers are not easily vulnerable against these methods, you need a firewall that will protect your network.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.
What’s good about this firewall is that it can be used by any person with a general knowledge about computers. He can simply plug the firewall in to his server and adjust a few or no settings to make it run on his managed servers. It is very easy to maintain because you only have to tinker with a single component as opposed to a software firewall that you must individually install and maintain in all of the machines in your network.
