Because iSCSI aims to consolidate storage for many servers into a single storage array, iSCSI deployments require strategies to prevent unrelated initiators from accessing storage resources. As a pathological example, a single enterprise storage array could hold data for servers variously regulated by the [[Sarbanes–Oxley Act]] for corporate accounting, [[Health Insurance Portability and Accountability Act|HIPAA]] for health benefits information, and [[PCI DSS]] for credit card processing. During an audit, storage systems must demonstrate controls to ensure that a server under one regime cannot access the storage assets of a server under another.

Typically, iSCSI storage arrays explicitly map initiators to specific target LUNs; an initiator authenticates not to the storage array, but to the specific storage asset it intends to use. However, because the target LUNs for SCSI commands are expressed both in the iSCSI negotiation protocol and in the underlying SCSI protocol, care must be taken to ensure that access control is provided consistently.
