Azure Key Vault Modified

Azure Key Vault Modified

edit

Because this data is sensitive and business critical, access to key vaults should be secured to allow only authorized applications and users.

Potential false positives

edit

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.
