PACKAGING PRODUCT SHIPMENT GROUP 3511-003 SCSI Enclosure Quick Reference Power Cord SECURITY, AUDITABILITY AND CONTROL Security and auditability features of the system in which this product is attached are: o A mechanical lock to allow the user to lock the system cover o A user-invoked password function used to prevent the use of the system by unauthorized persons. LIMITATIONS: SCSI, as defined in the ANSI standard X3.131-1986, provides for multiple SCSI adapters (initiators) on the SCSI bus. The SCSI bus may be internal or external to the system unit. The PS/2 SCSI adapters are in conformance with this standard and have an external port. A data security exposure exists even with Power-On Password installed, since external SCSI adapters can attach through the external SCSI port and gain undetected read or write access to data stored on internal and external SCSI devices. Physical access to the system and external SCSI devices must be controlled to limit this exposure. User management is responsible for evaluation, selection and implementation of security features, administrative procedures and appropriate controls in application systems and communications facilities.
