Prevent the use of unauthorized hardware components by carefully recording all serial numbers as components are received and taken into inventory. Before any component is installed or used, confirm its authenticity by comparing its serial number against what was recorded when the component was received. Follow these practices to secure hardware:
Keep a record of the serial numbers of all your hardware.
Security-mark all significant items of computer hardware, such as replacement parts. Use special ultraviolet pens or embossed labels.
Keep hardware activation keys and licenses in a secure location that is easily accessible to the system manager in system emergencies. The printed documents might be your only proof of ownership.
Wireless radio frequency identification (RFID) readers can further simplify asset tracking. Refer to the Oracle white paper, How to Track Your Oracle Sun System Assets by Using RFID, at http://www.oracle.com/technetwork/articles/systems-hardware-architecture/o11-001-rfid-oracle-214567.pdf.
