COMPUTER NETWORKING

Detailed explanation-1: -While Network Based Firewall filters traffic going from Internet to secured LAN and vice versa, a host based firewall is a software application or suite of applications installed on a single computer and provides protection to the host.

Detailed explanation-2: -Network-based firewalls are deployed in line with the traffic flow, protecting the entire network. Host-based firewalls are operated on single computers, via OS-run software.

Detailed explanation-3: -Software Firewalls A software firewall (or a host firewall) installs directly on the host device. This type of firewall protects only one machine (network endpoint, PC, laptop, server, etc.), so admins must install a version of the software on each device they want to protect.

Detailed explanation-4: -Software-based firewalls Host firewall software needs to be installed on each device requiring protection. As such, software-based firewalls consume some of the host device’s CPU and RAM resources. Software-based firewalls provide individual devices significant protection against viruses and other malicious content.

Detailed explanation-5: -Software firewalls can monitor traffic trying to leave your computer as well, preventing it from being used to attack other networks or devices. A software firewall has to be installed on each computer in the network. Therefore, a software firewall can only protect one computer at a time.
