Certificate Audit Solution

Purpose

The purpose of this solution is to pull meaningful certificate information into Automate to be monitored, reported on, or stored for periodic checkups in a dataview.

Update Notice 19-Sept-2024

New Content:

• Internal Monitor: ProVal - Production - Local Machine Certificate Audit
• Alert Template: △ Custom - Local Machine Certificate Audit

Modified Content:

• Script: Windows - Certificates (My) - Local Machine - Audit
• Dataview: SSL Certificate Audit [Script]
• Internal Monitor: ProVal - Production - Certificate Expiration < 30 Days

Modifications:

• The Windows - Certificates (My) - Local Machine - Audit script has been modified to use the Shell function instead of the Execute PowerShell function, as Threatlocker was flagging it.
• With the introduction of the ProVal - Production - Local Machine Certificate Audit internal monitor, the Windows - Certificates (My) - Local Machine - Audit script no longer needs to be scheduled against the group.

Note:

• It is suggested to use the Local Machine Certificate Audit internal monitor to execute the script instead of scheduling it against groups.
