Which of the following is not considered a logical or technical access control?

RAID Arrays are primarily a data storage solution, and while they may offer some level of redundancy and fault tolerance, they do not function as access controls. Logical or technical access controls are mechanisms designed to protect the integrity, confidentiality, and availability of information systems by regulating who can access data and how.

Firewalls, encryption protocols, and access control lists all fall under the category of technical access controls. Firewalls prevent unauthorized access by filtering incoming and outgoing network traffic. Encryption protocols protect data in transit or at rest by making it unreadable without the proper decryption keys, ensuring that only authorized users can access the information. Access control lists specify which users or systems have permission to access certain resources, effectively managing authorization within an information system.

In contrast, RAID arrays focus on data management and reliability rather than controlling who can access that data, thereby distinguishing them from the other options.
