Disable the ability to boot from a floppy or CD ROM on physically unsecured systems.
There are a number of 3rd party utilities that pose a security risk if used via a boot disk (including resetting the local administrator password.) If your security needs are more extreme, consider removing the floppy and CD drives entirely. As an alternative, store the CPU in a locked external case that still provides adequate ventilation. You can also restrict access to the floppy and CD-ROM drives in Windows XP Professional via the Local Computer Policy in the MMC (Click Start > Run > type GPEDIT.MSC > Go to Computer Configuration > Windows Settings > Security Settings > Local Policy > Security Options )
Disable AutoRun for the CD-ROM
One of the easiest ways for a hacker with physical access to a company's PC's to distribute malicious code is via the CD-ROM. By creating a custom CD with a payload set to launch from the autorun feature in any machine, a hacker can affect any number of unlocked systems without ever leaving a fingerprint or touching a keyboard. Or he/she can simply leave a few of these lying around the office marked "MP3's", or "Payroll Data" and wait for an unsuspecting user to simply pick it up and insert it into their machine. You can disable this function in Windows XP Professional by clicking Start > Run > and type GPEDIT.MSC Then go to Computer Configuration > Administrative Templates > System > Locate the entry for Turn autoplay off
