How many persons are mandated to maintain Two-Person Integrity (TPI)?

Two-Person Integrity (TPI) is a security protocol designed to enhance the protection of sensitive or classified information by ensuring that no individual has sole access to critical processes or materials. The key principle of TPI is that at least two authorized individuals must be present during operations that involve sensitive data or actions. This requirement reduces the risk of unauthorized access or tampering, as both individuals must work together to complete the task, thereby providing a check and balance on each other's actions.

The necessity for two persons ensures that there is oversight and accountability, which is vital in maintaining the integrity of the security processes in place. By requiring the presence and participation of two individuals, TPI effectively mitigates the risks associated with human error or malicious intent, which could jeopardize sensitive information or operations.
