KQL Search

This query is designed to identify devices that are vulnerable to some of the most exploited security vulnerabilities in 2022. Here's a simple breakdown of what the query does:

1. Define a List of Vulnerabilities: It starts by creating a list of Common Vulnerabilities and Exposures (CVEs) that were most exploited in 2022. These include vulnerabilities in products from companies like Microsoft, Fortinet, Zoho, Atlassian, Apache, VMware, and F5 Networks.

2. Filter Devices: The query then checks which devices in the network have these vulnerabilities. It looks for devices that have any of the listed CVEs.

3. Add Contextual Information: For each vulnerable device, the query retrieves additional information about the vulnerability, such as a description, by joining with another dataset that contains detailed information about each CVE.

4. Output Results: Finally, it outputs a list of devices, their operating systems, the specific CVE they are vulnerable to, and a description of the vulnerability. This information can be used to prioritize patching efforts to secure the network.

The query is part of a cybersecurity effort to prevent breaches by identifying and addressing known vulnerabilities that attackers have frequently exploited.
