Endpoint Standard: Horizon TrueSSO Fails At Login

Products

• Carbon Black Cloud Endpoint Standard (formerly Cb Defense)

Issue/Introduction

• Horizon TrueSSO Fails At Login

Environment

• Endpoint Standard
• 3.8.0.627 Windows Sensor

Cause

• Additional Sensor Tamper Protection added for 3.8.0.627 causes Horizon TrueSSO to fail

Resolution

• Add the following Permissions Rule to the required policies...

[Application path] c:\program files\vmware\vmware view\agent\bin\wsnm.exe
[Application path] c:\windows\system32\csrss.exe
[Operation Attempt] Scrapes memory of another process
[Action] Allow

Additional Information

• It is imperative that the rule is set to an 'Action' of 'Allow' and NOT 'Allow & Log' in order to work
• Engineering is working to add this to the product by default, so there would not be any need to manually add this rule (This KB will be updated when this has been added to the product)
