How to audit certificate expiration on endpoints
The 'InCommon\UofI ADCS Cert Expiration Audit' configuration baseline queries the endpoint for any Active Directory Certificate Services (ADCS) or InCommon certificates.
In the MECM console, navigate to \Assets and Compliance\Overview\Compliance Settings\Configuration Baselines
Select the 'InCommon\UofI ADCS Cert Expiration Audit' configuration baseline
Select 'Deploy' from the top ribbon
In the 'Deploy Configuration Baseline' dialog box, select the collection to run this configuration baseline on
Select 'OK'
Navigate to \Monitoring\Overview\Deployments and search for 'InCommon\UofI ADCS Cert Expiration Audit' in the search bar
Select 'InCommon\UofI ADCS Cert Expiration Audit' from the results and select 'View Status' from the top ribbon
Allow enough time for clients to run the baseline and report the results to MECM. Select 'Run Summarization' from the top ribbon to gather the latest reported data.
Devices under the 'Compliant' tab have certificates with more than 31 days remaining
Devices under the 'Non-Compliant' tab either have certificates with 31 days or less remaining, an expired certificate, or no certificate
For non-compliant devices, direct the respective users to connect to the VPN
This allows the device to contact the Active Directory and obtain a renewed certificate from ADCS. Devices must be connected to the VPN long enough to allow these steps to take place.
A graphical compliance report can be generated on a recurring basis:
Navigate to \Monitoring\Overview\Reporting\Reports\Useful Reports in the console
Select the 'Baseline Status by Collection' report
Select 'Create Subscription' from the top ribbon
Customize the subscription schedule
Select the relevant collection and baseline under 'Subscription Parameters'
