Claim:
A SCSI Enclosure Services (SES) device server, the SES device server comprising: a frontend interface operable to receive SES commands generated by Small Computer System Interface (SCSI) devices; a backend interface operable to manage operations of at least one peripheral device communicatively coupled with the SES device server based on received SES commands; and a control unit operable to determine whether a SCSI initiator that generated a received SES command is an authorized device, operable to perform the SES command in response to determining that the SCSI initiator is an authorized device, and further operable to reject the SES command in response to determining that the SCSI initiator is not an authorized device, wherein there are multiple SCSI initiators, and the control unit is further operable to maintain a security table that correlates an address of each SCSI initiator with one of multiple permission levels, where each permission level enables access by a SCSI initiator to a different range of SES commands.
