1. Session Initiation: When a user requests access to a target system (via the CyberArk PVWA/Privilege Cloud portal), this service receives the request to "initiate session."
2. Credential Injection: It coordinates with the CyberArk Vault to retrieve the credentials for the target system. Crucially, the credentials are injected into the session memory and are (ideally) never exposed to the end-user.
3. Protocol Handling: It manages the underlying protocols (RDP, SSH, Telnet, VNC) to establish a connection between the PSM server (the jump server) and the target machine.
4. Session Monitoring: It facilitates the real-time monitoring capabilities of PSM, allowing security teams to view or record the session.
