Why each option
LUN masking is the primary method storage administrators use on a storage array to restrict access to specific LUNs, ensuring only authorized servers can see and utilize them.
LUN masking is a security feature implemented on storage arrays that controls which host initiators (identified by their WWN for Fibre Channel or iSCSI initiator name for iSCSI) can access specific Logical Unit Numbers (LUNs). This prevents unauthorized servers from discovering or writing to storage allocated to other servers.
LUN provisioning is the process of allocating and configuring storage on the array to make it available for use by servers, but it is not a security mechanism itself.
LUN controlling is not a standard or recognized term for a specific storage security feature or administrative action.
LUN establishing is not a standard or recognized term for a specific storage security feature or administrative action.
