Abstract
Enhanced configuration of security and access control for data in a storage device is disclosed. A request is received to access an addressable memory location in a storage media within the storage device. A set of addressable memory locations with contiguous addresses identified by an address range is associated with first and second characteristics. The first characteristic is applied if the addressable memory location is within the set of addressable memory locations, and an entity is currently authenticated to and authorized to access the set of addressable memory locations. The second characteristic is applied if the addressable memory location is within the set of addressable memory locations, and no entity is currently authenticated to and authorized to access the set of addressable memory locations. The set of addressable memory locations can also be a logical partition, where the first and second characteristics are stored in a logical partition table.
