In Splunk®, SOC groups can use alerts to watch for and reply to particular Chrome Browser Cloud Administration occasions. Alerts use a saved search to search for occasions in actual time or on a schedule and may set off an Alert Motion when search outcomes meet particular situations as outlined within the diagram beneath.

Use Case

If a person downloads a malicious file after bypassing a Chrome “Harmful File” message their managed browser/managed CrOS system must be quarantined.

Conditions

Setup

1. Set up the Google Chrome Add-on for Splunk App

5. Organising a Quarantine OU in Chrome Browser Cloud Administration

   Create a “Quarantine” OU to maneuver managed browsers into. Apply restrictive insurance policies to this OU which can then be utilized to managed browsers and managed CrOS gadgets which can be moved to this OU. In our case we set the beneath insurance policies for our “Quarantine” OU known as Examine.These insurance policies be sure that the quarantined CrOS system/browser can solely open a restricted set of permitted URLS.

Configuration

1. Begin with a seek for the Chrome Browser Cloud Administration occasions within the Google Chrome Add-on for Splunk App. For our occasion we used the beneath search question to seek for recognized malicious file obtain occasions.

2. Save the search as an alert. The alert makes use of the saved search to examine for occasions. Regulate the alert kind to configure how typically the search runs. Use a scheduled alert to examine for occasions frequently. Use a real-time alert to watch for occasions repeatedly. An alert doesn’t must set off each time it generates search outcomes.
