For any computer system which is logged in to the internet, installing a firewall is a necessity. But what is a firewall? And why exactly do we need a firewall to be installed in our system?
A firewall is basically a protective shield for your computer that tries to guard your system from threats on your local network as well as the internet. There are multiple ports in your computer and each one of them is responsible for the transmission of some specific information over a network. A firewall basically seals off the ports in your computer that you do not require presently and only allow ports responsible for e-mailing, browsing etc to function thereby protecting your system against attacks from other sources in the internet.
So what is a dedicated firewall?
A dedicated firewall provides protection to a single server unlike shared firewalls which do the same for multiple servers. Hence, it’s pretty obvious that a dedicated firewall provides a higher level of security as opposed to a shared firewall.
