A firewall can either be software based or hardware based and is used to help keep a network secure. They are either a software appliance running on general-purpose hardware, a hardware appliance running on special-purpose hardware, or a virtual appliance running on a virtual host controlled by a hypervisor. It is customizable, allowing the user to control its functionality and protection features. In this regard, how do firewalls manage incoming and outgoing traffic?
Unlike a software firewall, a hardware firewall has its resources and doesnt consume any CPU or RAM from the host devices. Firewall & antivirus software. It is less vulnerable to viruses or malware attacks and capable of dealing with a more significant traffic load than a software product. They represent a first line of defense because they can stop a malicious program or attacker from gaining access to your network and information before any potential damage is done. b) Host - based firewalls provide a layer of software on one host that controls network traffic in and out of that single machine There are two basic types of firewalls: Application Proxy and Gateway. A software firewall is internal a program on your computer that works through port numbers and applications. The number of layers envelops by a firewall is dependent upon the type of firewall used.
