Explanation
Security Admins are the built-in group that can view and configure Automatic Remediation and Session Analysis and Response in the PVWA. These features are part of the Privileged Threat Analytics (PTA) module, which is designed to detect and respond to anomalous activities and risky behaviors in the privileged environment. Security Admins have the permissions to access the PTA settings and configure the policies and actions for Automatic Remediation and Session Analysis and Response. References:

Explanation
During the Windows discovery process in CyberArk Defender PAM, accounts that can be selected for use include an account that is already stored in the Vault and an account that is specified by the user. The discovery process scans predefined machines for new and modified accounts and their dependencies. After the scan, accounts that should be onboarded into the Vault for secure and automatic management are identified12.
