PennNet UNIX Systems: User Password Responsibilities

You may not authorize anyone to use your account(s) for any reason. You are responsible for all use of your accounts. You must take all reasonable precautions, including password maintenance and file protection measures, to prevent use of your accounts by unauthorized persons.

You may not use password guessing or password sniffing programs, nor may you use any other techniques to gain unauthorized access to other user accounts or systems accounts.

You should make reasonable efforts to select and use a secure password as well as to protect your password. Having a vulnerable password is not only a danger to you and your files; it is a danger to our entire network of systems, and to some extent, a danger to the entire worldwide Internet. The staff routinely runs a series of security programs which, among other things, attempt to guess user passwords. If your password is discovered in this way, your password will be expired. The next time that you attempt to login, you will be able to use your old, insecure password but you will be prompted to change your password immediately.

If your password has been expired, you will see the following as your login.

          Your password has expired.
