Firewall Policy Creation

This guide will provide background information on creating a new set of Windows Defender Firewall settings that will be enforced to the specified onboarded Intune device group.

Endpoint Firewall

While many security practitioners are familiar with managing a central firewall, a newer concept to some may be the management of an endpoint firewall. While endpoint firewalls represent a typographically different approach to managing network traffic, with the help of the Endpoint Management Console, management of all corporate device firewalls can work to imitate the functionality of a centrally located firewall arrangement. By publishing firewall rules, the devices will abide by those rules as a collective and allow for changes in rules to be made easily and quickly.
