Account Policies

There are a number of policies which apply to NERSC users. These policies originate from a number of sources, such as DOE regulations and DOE and NERSC management.

User Account Ownership and Password Policies

A user is given a username (also known as a login name) and associated password that permits her/him to access NERSC resources.  This username/password pair may be used by a single individual only.

Passwords may not be shared and must be created or changed using specified rules.  See NERSC Passwords

NERSC will disable a user who shares any one of her/his passwords with another person.  If a person using a username/password pair is not the one who is officially registered with NERSC as the owner of that username, then "sharing" has occurred and all usernames associated with the owner of the shared username will be disabled.

If a user is disabled due to account sharing, the PI or an authorized project manager must send a memo to consult@nersc.gov explaining why the sharing occurred and assuring that it will not occur again. NERSC will then determine if the user should be re-enabled.

The computer use policies and security rules that apply to all users of NERSC resources are listed in the Computer User Agreement form.

Security Incidents

If you think there has been a computer security incident you should contact NERSC Security as soon as possible at security@nersc.gov.  You may also call the NERSC consultants (or NERSC Operations during non-business hours) at 1-800-66-NERSC.

 Please save any evidence of the break-in and include as many details as possible in your communication with us.
