Description

Identifies modifications to a Key Vault in Azure. The Key Vault is a service that safeguards encryption keys and secrets like certificates, connection strings, and passwords. Because this data is sensitive and business critical, access to key vaults should be secured to allow only authorized applications and users. This is a New Terms rule that detects when this activity hasn't been seen by the user in a specified time frame.

Detection logic

Its licence does not clear it for publishing here

Sunturai publishes a detection's own text where the licence it arrived under has been reviewed and permits it, and Elastic License 2.0 has not. The query as its source wrote it, its canonical form and the hash that pins this revision are in the workspace record.

Detection requirements

Platform
IaaS

The rule states no platform. This is derived from the ATT&CK technique it maps to.

Log source category

Known benign triggers

  • Key vault modifications may be done by a system or network administrator. Verify whether the username, hostname, and/or resource name should be making changes in your environment. Key vault modifications from unfamiliar users or hosts should be investigated. If known behavior is causing false positives, it can be exempted from the rule.
