Block Users

You can block users from accessing either all applications or only selected applications. The block operation requires the listed policy rules to be edited to block the users from accessing one or more applications. You can view policy changes by clicking the policy name or view affected devices by clicking the device count. You see only policies permitting this traffic in the past 30 days.

Note:

Starting in Junos Space Security Director Release 21.1, when unified policy rules permit the traffic, selecting block action creates block rules in the appropriate unified policy.

To block a user:

  1. Select Monitor > Applications.

    The Application Visibility page is displayed.

  2. Click the USERS tab.

    The top 50 users are displayed.

    Click the View All Applications link to display the applications accessed by the user.

  4. Click Block User to block the selected IP address or username from accessing all the applications.

    The Block User page is displayed with policies that contain the rules required to block the user. The listed policies will be edited to block the selected user from accessing all applications.
