iSCSI Security

For an iSCSI interface, the iSCSI authentication function can be used when the initiator accesses the target. The
iSCSI authentication function is available for host connections and remote copying.
The Challenge Handshake Authentication Protocol (CHAP) is supported for iSCSI authentication. For CHAP Au-
thentication, unidirectional CHAP or bidirectional CHAP can be selected. When unidirectional CHAP is used, the
target authenticates the initiator to prevent fraudulent access. When bidirectional CHAP is used, the target au-
thenticates the initiator to prevent fraudulent access and the initiator authenticates the target to prevent imper-
sonation.
Note that the Internet Storage Name Service (iSNS) is also supported as an iSCSI name resolution.
