Blocking Images on Google

Article #: Product: Version:
KB- Guardian  

Summary:

This article shows you how to set the Smoothwall to block specific images on the Google Image search results.

Problem:

Even with ‘Force SafeSearch’ switched on, sometimes it might not filter out some inappropriate images.

Solution:

To make this work successfully, there are three steps involved:

  1. Set up a HTTPS Decrypt and Inspect policy:
    1. Go to Guardian > HTTPS inspection > Policy wizard.
    2. Create your new policy:
      • Who: Everyone*
      • What: Web Search, Content Delivery
      • Where: Everywhere*
      • When: Always*
      • Action: Decrypt and inspect
      • Make sure you place the policy at the top of the policy table.

  2. Set up the Force SafeSearch content modification:
    1. Go to Guardian > Content modification > Manage policies.
    2. Create your new policy as follows:
      • Who: Everyone*
      • What: Everything
      • Where: Everywhere*
      • Action: Apply Force SafeSearch
      • Make sure you place the policy at the top of the policy table.

  3. Set up a custom category of Images to block:
    1. Go to Guardian > Policy Object > Categories.
    2. Under the Manage Categories section, type your category Name, for example, Blocked Images.
    3. For the image that you want to block, right-click on it and select the option to copy the image's URL:
    4. In the Domain/URL filtering section paste the image's URL and click Save.
    5. Go to Guardian > Web Filter > Policy Wizard.
    6. Create your new policy as follows:
      • Who: Everyone*
      • What: Blocked Images
      • Where: Everywhere*
      • When: Always*
      • Action: Block
      • * Change as appropriate

Note: Customers on a release before Leeds-1 also need to set up this content modification: QUIC removal.

Users can no longer view the blocked image:
