Firewall, being the cornerstone of network security, helps protect corporate networks by blocking unwanted traffic. This can happen at two levels—network and host levels.
A network level firewall regulates and manages the traffic entering the perimeter of your network. Whereas, the host level firewall is deployed on individual hosts and blocks attackers from gaining access to particular ports or applications even if they have trespassed the network firewall.
An IP, once identified as malicious, can be blocked at either the host or network level. The steps to block an IP on a network level firewall will depend on the version, type, and vendor of the firewall. Whereas, steps for configuring the host level firewall depends on the operating system of the host in which it's deployed.
This article, elaborates the steps to block an IP in Windows Firewall.
