What are Host-Based Firewalls?
A host-based firewall is a type of software firewall that runs on an individual computer or server and controls the incoming and outgoing network traffic.
Why is it Necessary?
A host-based firewall is necessary to provide an additional layer of security for a computer or server. While network-based firewalls can protect an entire network, they do not provide sufficient protection for individual systems. A host-based firewall can monitor and control the incoming and outgoing network traffic for a specific computer or server, helping to prevent unauthorized access, malware, viruses, and other types of attacks. It can also be customized to meet the specific security needs of the system, and can be configured to allow only approved traffic to enter or leave the host. By providing this additional layer of protection, a host-based firewall helps to keep sensitive data and systems secure, and reduces the risk of data breaches and cyber attacks.
