This article provides the steps to enable Micro Applications in UTM (Unified Threat Management) on Juniper SRX devices

Micro-applications are included in the application signature package and represent sub-functions within a larger application.

They allow for granular control at the feature level, making it possible to permit or block specific functionalities such as file transfers or chat instead of the entire application.

By default, detection of micro-applications is disabled.

To leverage this functionality, you must first enable micro-application detection within Application Identification, after which they can be used as match criteria in security policies.

To enable Micro Applications, follow these steps:
