Explanation
PSM captures a record of each command that was executed in Unix by using the SSH text recorder. This is a feature that enables PSM to record all the keystrokes that are typed during privileged sessions on SSH connections, including Unix systems. The SSH text recorder can be configured in the Platform Management settings for each platform that uses the SSH protocol. The text recordings are stored and protected in the Vault server and are accessible to authorized auditors. The text recordings can also be used for auditing and compliance purposes, as they provide a detailed trace of the actions performed by the users on the target systems1. References:
