What Does Host-Based Firewall Mean?
A host-based firewall is a piece of firewall software that runs on an individual computer or device connected to a network. These types of firewalls are a granular way to protect the individual hosts from viruses and malware, and to control the spread of these harmful infections throughout the network.
Techopedia Explains Host-Based Firewall
Some companies use host-based firewalls in addition to perimeter-based firewalls in order to enhance internal security. For example, some of the malware attacks that may get past a perimeter firewall can be stopped at the individual device or workstation, using a host-based firewall.
A host-based firewall setup can also be simpler for some users. The host-based firewall can also be configured to the particular computer, where customization can make the firewall more effective.
