MTCS (Singapore) 24.6: Storage area networks (SAN)

Storage area networks. Level 1 (a and b): authorised access to storage networks and network security management. Level 2 (a to e): access control and network protection; port controls restricting each port's function; protected storage communications with certificate and key management; storage devices answering only authorised devices; and automatic replication. Level 3 (a to d): hard zoning in the Fibre Channel switch; LUN masking; encryption of stored data and of data moving between storage devices; and customer options to control the encryption keys. The SAC criteria let an IaaS provider replace the SAN with other backup solutions.
