What does TPI stand for in the context of security protocols?

In the context of security protocols, TPI stands for Two-Person Integrity. This concept is a safeguard measure used to prevent unauthorized access to sensitive information or resources. The principle of Two-Person Integrity requires that two individuals must be involved in the handling or access of critical assets, thereby mitigating the risk of fraud, error, or malicious activities.

By ensuring that no single individual has complete control over sensitive tasks, organizations can promote accountability and reinforce security measures. This practice is particularly important in environments where the stakes are high, such as in military or classified information scenarios, where maintaining the confidentiality, integrity, and availability of information is critical.

While the other options refer to various concepts that may exist in different contexts, they do not align with the established security principle that TPI embodies in secure environments. Thus, Two-Person Integrity stands out as the correct and relevant definition in this situation.
