What is the primary purpose of Master Policy Rule 1?

The primary purpose of Master Policy Rule 1 is to require dual control password access approval. This rule is integral in enhancing security by ensuring that no single individual has complete control over privileged passwords, thereby reducing the risk of unauthorized access or misuse. By mandating that two separate approvals are needed before access to certain sensitive credentials can be granted, the rule promotes accountability and oversight.

In environments where sensitive operations are conducted, enforcing dual control is critical to prevent accidental or malicious actions. This practice aligns with security best practices, emphasizing the importance of checks and balances in managing privileged access.

The other options do not accurately capture the focus of Master Policy Rule 1. While enforcing user monitoring, allowing transparent connections, and implementing session isolation are important security measures, they are not the primary objective of this specific rule. Instead, they serve different aspects of the overall security framework in CyberArk's approach to managing privileged access.
