What is the purpose of a firewall rule in Sophos XG Firewall?

The purpose of a firewall rule in Sophos XG Firewall is primarily to determine which traffic is allowed or denied based on set conditions. These rules form the core of the firewall's operation by defining criteria that govern the flow of data through the network. This includes specifying the source and destination of the traffic, the services or applications involved, and the action to be taken (allow or deny) based on these parameters.

Having these rules in place is essential for controlling network security, as they help in enforcing policies, preventing unauthorized access, and ensuring that only legitimate traffic can traverse the firewall. By configuring these rules accurately, you can effectively manage the network's security posture and protect it from potential threats.

While logging traffic, performing deep packet inspection, and providing URL filtering capabilities are important functionalities of the Sophos XG Firewall, they are supplementary features that support the overall security strategy but do not encapsulate the primary purpose of a firewall rule itself.
