SecurID: Protection for Administrative Computers

Some administrative computer systems at the University of Washington require verification beyond the usual login name and password. Staff who need access to these systems use a security mechanism called a SecurID card, made by Security Dynamics Technologies, Inc.

Preventing Unauthorized Access

Each SecurID card generates a new, random access code every 60 seconds that is displayed on its glass liquid crystal display (LCD) screen. This six-digit number is known only by the computer that is the SecurID server and the card itself. Once that number has been used to log in to a system, it cannot be used again. This prevents reuse by someone observing your login or sniffing the session.

Protecting Your Protection

Protect your SecurID card by not lending it to anyone and not leaving it on your desk or next to your computer where it can be taken or used by someone else. Keep it with you or lock it in a desk drawer or filing cabinet for safekeeping. Do not put any identifying information on or with your card.
