Overview¶

IBM Security SOAR app for ‘fn_googlesafebrowsing’

screenshot: main

This app uses Google Safe Browsing to check artifacts with a URL type and adds a hit if the site is potentially unsafe. The hits contains a link to Google Transparency Report that gives information on the potentially unsafe url.

Key Features¶

The workflow checks the reputation of the url and creates a hit in the artifact if Google Safe Browsing thinks it is potentially unsafe.

Requirements¶

resilient-circuits>=43.0.0 This app supports the IBM Security QRadar SOAR Platform and the IBM Security QRadar SOAR for IBM Cloud Pak for Security.

SOAR platform¶

The SOAR platform supports two app deployment mechanisms, App Host and integration server.

If deploying to a SOAR platform with an App Host, the requirements are:

SOAR platform >= 43.1.49.
The app is in a container-based format (available from the AppExchange as a zip file).

If deploying to a SOAR platform with an integration server, the requirements are:

SOAR platform >= 43.1.49.
The app is in the older integration format (available from the AppExchange as a zip file which contains a tar.gz file).
Integration server is running resilient-circuits>=43.0.0.
If using an API key account, make sure the account provides the following minimum permissions:

Name

The following SOAR platform guides provide additional information:

App Host Deployment Guide: provides installation, configuration, and troubleshooting information, including proxy server settings.
Integration Server Guide: provides installation, configuration, and troubleshooting information, including proxy server settings.
System Administrator Guide: provides the procedure to install, configure and deploy apps.

The above guides are available on the IBM Documentation website at ibm.biz/soar-docs. On this web page, select your SOAR platform version. On the follow-on page, you can find the App Host Deployment Guide or Integration Server Guide by expanding Apps in the Table of Contents pane. The System Administrator Guide is available by expanding System Administrator.

Cloud Pak for Security¶

If you are deploying to IBM Cloud Pak for Security, the requirements are:

IBM Cloud Pak for Security >= 1.9
Cloud Pak is configured with an App Host.
The app is in a container-based format (available from the AppExchange as a zip file).

The following Cloud Pak guides provide additional information:

App Host Deployment Guide: provides installation, configuration, and troubleshooting information, including proxy server settings. From the Table of Contents, select Case Management and Orchestration & Automation > Orchestration and Automation Apps.
System Administrator Guide: provides information to install, configure, and deploy apps. From the IBM Cloud Pak for Security IBM Documentation table of contents, select Case Management and Orchestration & Automation > System administrator.

These guides are available on the IBM Documentation website at ibm.biz/cp4s-docs. From this web page, select your IBM Cloud Pak for Security version. From the version-specific IBM Documentation page, select Case Management and Orchestration & Automation.

Proxy Server¶

The app does support a proxy server.

Python Environment¶

Python 3.6 is supported. Additional package dependencies may exist for each of these packages:

resilient-circuits>=43.0.0

Endpoint Developed With¶

To install or uninstall an App on IBM Cloud Pak for Security, see the documentation at ibm.biz/cp4s-docs and follow the instructions above to navigate to Orchestration and Automation.

App Configuration¶

The following table provides the settings you need to configure the app. These settings are made in the app.config file. See the documentation discussed in the Requirements section for the procedure.

Config	Required	Example	Description
googlesafebrowsing_api_key	Yes	``	API key retrieved from Google Cloud Platform
googlesafebrowsing_url	Yes	`https://safebrowsing.googleapis.com/v4/threatMatches:find?key=`	—

Function - Google Safe Browsing¶

This app uses Google Safe Browsing to check artifacts with a URL type and adds a hit if the site is potentially unsafe. The hit contains a link to Google Transparency Report that gives information on the potentially unsafe url.
