Setting Up Keyword-Based Blocking on Search Engines

 

Netskope Cloud Version - 121

 

Objective

This document provides guidance around configuring keyword based blocking on search engines

 

Prerequisite

Netskope SWG Entitlement is required

 

Context

Many customers have specific requirements about blocking search of specific keywords on Search engines.

This use case is around such a requirement and will demonstrate how to configure keyword based blocking on search engines.

 

Lab Recreate

For this example, we will create a policy that will block the search of keywords - “Sport” and “Sports” on a search engine like google.

AD_4nXftWYW-BtzS1OO10T_mTXIUJ7unHtP3H90ZK5XO7SkqreF-8VaDXo0A03qFNKB3CcxfDavbGlye1BPy0cLhVHuQDqH_Gzdk2DGBEldc4v_pksOZqzkLRLiG5fo9lDi2xzrP21dV8Hmh7hojCXRXeUI?key=uCZEFOiSXf49scj2GsVMbz1l

This can be done by creating a regex that matches the keywords “sport” and “sports” in the search panel of Search engine.

However, the regex should also ensure that a keyword such as “Sportland” should not get blocked.

To create a Regex and understand the supported syntax, you can leverage this document from Netskope Knowledge base

 

Below steps can be followed to accomplish this use case :

To validate the regex you can use Regex Tester Tools

Step 1 : Create a custom URL list under Policies - Web - URL List - New URL List with the first regex that will match “sport” and “sports” : Regex : .*search.*\bsport(?:s)?\b.*|^.*\bsport(?:s)?\b.*search.*

Path: Netskope Tenant UI >>> Policies >>> Profile --- URL List >>> New URL List

Step 2: Now create a Custom category with the URL list created in Step 1: 

Path: Netskope Tenant UI >>> Policies >>> Profile --- Custom category >>> New Category

Step 3: Now go to the Real time protection policy page under Policies - Real Time protection policies - Web and create a Real time protection policy as shown below: 

Path: Netskope Tenant UI >>> Policies >>> Profile --- Custom category >>> New Category

Now, when a user tries to search with the keywords “Sport” and “Sports”, the action will be blocked
