What is the term for the strategy that limits access to a high value asset by requiring multiple processes or individuals?

1. Overlapping redundancy

2. Segregation

3. Vertical defense in depth

4. Multi-factor authentication

The correct answer is: Segregation

The term that describes the strategy of limiting access to a high-value asset by requiring multiple processes or individuals is known as segregation. This approach involves dividing responsibilities and access rights among different individuals or teams to ensure that no single entity has the ability to access or control sensitive assets independently. By doing so, it mitigates the risk of unauthorized access and potential misuse, as it becomes necessary for multiple parties to collaborate to gain access to the asset. Segregation is a critical component of security best practices, particularly in environments where sensitive information or critical systems are involved. It reinforces accountability and helps to create a more robust security posture by requiring that various checks and balances are in place before access to key assets is granted. The other options do not adequately describe this concept. For instance, overlapping redundancy refers to the inclusion of multiple systems or processes to increase reliability but does not specifically address access control. Vertical defense in depth pertains to layered security measures within a single access point rather than involving multiple parties for asset access. Multi-factor authentication provides a method for verifying identity but does not address the need for collective access control inherent in segregation.
