Prevent MP3 files and other file types from being downloaded

Using the real-time alert rules within GAT Shield an admin can set up a rule to prevent certain file types from being downloaded to a user’s device.

To set up a download rule, go to the Configuration section of GAT Shield. And enter the Alert Rules section.

select "alert rules"

Click on the Add a rule button, and select File download.

Click on the Add a rule button, and select File download.

Once the menu appears, do the following:

  • Give the rule a meaningful name, in my case, I will prevent mp3 and mp4 files from being downloaded.  
  • Make sure to enable ‘Active’ so that the rule will be active once the rule set up is complete.
  • I entered mp3;mp4 I used a semicolon to separate the two file types. A semicolon is not necessary if only one file type is being covered.

Tick the boxes next to "active" and "cancel/delete download"

  • You have an option available to block files based on their file size as well. Anything equal to or above the value you have entered. For example, I can enter 20 MB. That means any mp3 or mp4 equal to or greater than 20 MB will be blocked from being downloaded others which are less won’t.  
  • The Cancel/delete download will be enabled because we want this rule to block and prevent downloads if left unchecked it would only notify you and not take any action.
  • Site exclusions are useful if you have some educational sites where downloading of mp3 or mp4 are allowed.

indicate which users will be covered by this rule.

  • Now we need to indicate which users will be covered by this rule. I have used the OU option, and I’ve selected the root user OU / and I have also included sub. Org units. This means my entire domain is covered by this rule (well actually users who have Shield deployed on their accounts). You can indicate a sub OU like /Students and enable the option to cover its sub-OUs if you wish.
  • You can also take actions like shutting the webpage down or showing a custom warning message to the students.
  • The last 3 options allow you to report the file name, capture the screen the user was on and take a picture of the user using the webcam of the device (if Shield Companion app is deployed as well).

All alerts will be sent to you via email and you can also find them in the Shield Alerts section.
