What is a ‘default policy’ in the context of Sophos XG Firewall?

In the context of Sophos XG Firewall, a default policy refers to a pre-configured policy that applies to all traffic unless overridden by more specific rules. This means that the default policy serves as a baseline for traffic management, ensuring that there is always a set of rules in place that govern how data is processed by the firewall, regardless of the type of traffic.

Default policies are essential as they simplify the management of traffic by providing a standard approach that can cater to various scenarios without needing to define specific rules for each possible case. Since this policy is applied universally, network administrators can focus on fine-tuning or creating more specific rules that override the default settings when needed.

The other options describe specific conditions or situations that do not align with the general applicability and foundational role of a default policy within the network security infrastructure of the Sophos XG Firewall.
