Which of the following storage configurations is the MOST secure with regards to unauthorized access to the storage?

DAS connected to a single standalone server is the most secure as the storage is directly controlled by one server, with no network exposure or shared access paths that could be exploited by unauthorized users.

NAS, even on an isolated network, is still network-attached and can be accessed by multiple clients, presenting more potential entry points for unauthorized access than DAS.

A hybrid storage array running multi-protocols typically implies network connectivity and complexity in managing security across different access methods, increasing the attack surface.

A SAN involves a dedicated network and multiple servers, which inherently presents a broader attack surface than direct-attached storage, even with user access controls in place.
