What is the purpose of session isolation as specified in the Master Policy Rules?

Session isolation is a critical feature in the CyberArk Privileged Access Security framework that ensures the security and integrity of privileged sessions. The main purpose of session isolation is to prevent unauthorized access during sessions. This means that during sessions involving sensitive information or critical systems, session isolation ensures that only authenticated users can access the session and that their operations are monitored and controlled. This is especially vital in environments where sensitive tasks are being performed, as it mitigates the risks of data breaches or unauthorized manipulation of critical systems.

By isolating sessions, CyberArk also prevents potential threats or malicious activities from affecting a session, thus enhancing the overall security posture of the privileged access management strategy. This ensures that even if a session is compromised, the scope of the attack is limited, and the integrity of other sessions is maintained.

While access control, resource sharing, and network efficiency are important aspects of session management and cybersecurity, they do not encapsulate the core purpose of session isolation as it pertains to preventing unauthorized access during active privileged sessions.
