3.11.0 Release notes

This section shows the most relevant improvements and fixes in version 3.11.0. More details about these changes are provided in each component changelog:

Wazuh core

Vulnerability detector

  • Windows support. Thanks to a combination of NVD feed and the Microsoft Security guide, the module is able to detect system vulnerabilities and software vulnerabilities.
  • Added support for Debian 10 and RHEL 8.
  • Vulnerability detector alerts include PCI-DSS mapping.

Inventory

  • Added extraction for Windows Security Updates (hotfixes).
  • Processes and ports are now supported in macOS.

Log collection

  • Allowed JSON escaping for logs in the output format.
  • Added the host’s primary IP in the output format.
  • Wildcards don’t detect directories as log files any more.

Analysis engine

  • Frequency based rules aggregate the counter for the same event source by default. Introduced a new setting to toggle this behavior: global_frequency.
  • Fields protocol, system_name, data and extra_data can now be used for event matching in rules creation.
