You created a new platform by duplicating the out-of-box Linux through the SSH platform.

 When a new platform is created by duplicating the out-of-the-box Linux through the SSH platform, it will support the SSH Text Recorder and the Universal Keystrokes Text Recorder by default. The SSH Text Recorder is designed to record all the keystrokes that are typed during privileged sessions on SSH connections1. The Universal Keystrokes Text Recorder can record all the keystrokes that are typed during privileged sessions on all supported connections1. These text recorders are automatically enabled at the Master Policy level and can be customized at the platform level1.
