What defines application segments in the Zscaler framework?

In the Zscaler framework, application segments are defined using a wildcard within an Application Segment. This allows for flexibility in applying policies and controls to a broader category of applications without specifying each one individually. By using wildcards, administrators can group together applications that fit certain criteria, ensuring that policy management is simplified and efficient.

This approach is particularly useful when managing applications that may have dynamic names or varied endpoints, as it allows for a more streamlined handling of security rules. Wildcards enable the inclusion of multiple applications under a single segment, making it easier for organizations to enforce consistent security policies across similar types of applications.

In contrast, defining applications by their size does not hold relevance in the context of application segmentation, as size does not determine how policies are applied. Specific ports are more related to network configuration than application segmentation. While applications that share the same functionality could potentially fall under the same segment, this is not the mechanism by which segments are fundamentally defined in the Zscaler framework.
