Unable to deploy SSL keys after deleting the server certificate from the Trellix IPS Manager

Technical Articles ID: KB93480
Last Modified: 2023-04-20 09:53:09 Etc/GMT

Environment

Trellix Intrusion Prevention System

Problem

You delete the only certificate present on the Sensor that's used for SSL inbound decryption. But, when you deploy the changes to the Sensor, you see the following error:

Deployment error: Reason: No valid SSL key file on Manager for sensor: <Sensor Name>.
Please select the individual sensor to update SSL configuration.

Solution

For SSL Decryption to work, the Sensor expects at least a single certificate.

If you want to delete the only available certificate and no other certificate is to be imported, you must disable the SSL Decryption function.
