Configuring Restricted File Extensions for Enhanced Content Security

Controlling the types of files that can be uploaded to your online portal is crucial for maintaining a secure environment. This article guides you through the process of setting up and managing restricted file extensions to enhance content security within your portal.

Prerequisite​

Before you begin, ensure that you are part of a group with the Restricted Formats Management feature permission enabled.

Accessing the Restricted Extensions Screen​

  1. Select the Menu icon at the top left of the screen to reveal the left navigation pane.
  2. Go to Admin > Control Panel.

Adding Restricted File Extensions​

  1. Go to Security > Restricted Extensions. The screen displays the list of currently restricted file extensions, if any.
  2. Enter the desired file extension in the designated field. For instance, if you want to restrict executable files, enter ".exe."
  3. Select Add Extension to include a new restricted extension.
  4. Select Update to save the changes.

Editing Restricted File Extensions​

To edit an existing restricted extension:

  1. Locate the extension in the list on the Restricted Extensions screen.
  2. Select the edit icon or select the extension directly to proceed with the changes.
  3. Edit the file extension as per your requirements.
  4. Select the update icon to preserve the changes.
  5. Select Update to apply and save the changes.

Deleting Restricted File Extensions​

To remove a restricted file extension:

  1. Locate the specific extension within the list displayed on the Restricted Extensions screen.
  2. Select the delete icon positioned next to the extension you intend to remove.
  3. Select Update to confirm the deletion.

Uploading Content and Error Handling​

When attempting to upload a file through the portal's user interface or via the API, the system performs an automatic check on the file's extension against the restricted extension list.

If the file's extension is found to be in the restricted list, an error message displays, indicating that the extension is restricted. The user is prompted to choose an alternative file that does not have a restricted extension.

Configuring restricted file extensions empowers you to selectively prohibit certain file types from being uploaded to your portal, enhancing content security, preventing the spread of malware, and maintaining compliance with content policies.
