Like many other universities, Caltech has been targeted recently by scammers who send email to Caltech users demanding that the recipient respond with username/password information, with a threat of account deletion if the recipient does not comply.

You must not log in using another individual's login name, or allow any other person to access facilities using your login name. You should therefore not leave unattended logins on publicly accessible systems.
You must set a secure login password and keep it secret (see Setting a new logon password). The choice of a secure password is essential both to the security of your own account and potentially to those of others as many means of "hacking" systems require the hacker to have an account on the system to which they can login.
Accounts on the systems are issued primarily for academic work. A small amount of recreational use is permitted but this must not interfere with academic use of the system or annoy or upset other users, e.g. by causing noise or displaying pornographic images.
Information belonging to other users is confidential. You must not read, access or modify any file not owned by you without the explicit permission of the owner.
