How to integrate vulnerability management in Azure Sentinel

Copper Contributor



During recent Azure Sentinel workshops some customers have asked for the possibility to ingest Vulnerability data into Azure Sentinel. In this blog, I will explain how to ingest and analyze vulnerability data in Azure Sentinel. I'm using tenable as an example, but it can be any Threat - Vulnerability Management (TVM) platform.


Before explaining how the Tenable vulnerability management solution integrates with Azure Sentinel, it is very important to understand the use case of each one of those solutions.


First, what is a vulnerability management solution?


A vulnerability management solution enables companies to discover and mitigate potential vulnerabilities on their networks.


To do so, vulnerability management solutions provide continuous asset discovery, assessment (vulnerability and compliance), reporting and analysis prioritization capabilities. In other words, vulnerability management solutions scan for potential vulnerabilities, alerts your security team, and help them prioritize the remediations tasks. 

Now that we understand what a vulnerability management solution is, why should vulnerability management solutions become a critical part of your SIEM/SOAR platform?


Asset information such as operating system services and vulnerabilities are critical for enriching events. Your SIEM can use Tenable's data to get asset information. Let me give an example: a SIEM solution can help determine not only whether there is traffic from an identified malicious internet location, but also whether this traffic goes to a vulnerable asset. This can both increase the severity of an incident in the SIEM system and provide feed back to the vulnerability management solution to prioritize vulnerability remediation for the vulnerable machine.


So, let's move to our main topic: How to automate vulnerability management using Azure Sentinel.
