Overview

Passwords are an important aspect of computer security. A poorly chosen password may result in unauthorized access and/or exploitation of Tuxis's resources. All users, including contractors and vendors with access to Tuxis systems, are responsible for taking the appropriate steps, as outlined below, to select and secure their passwords.

Purpose

The purpose of this policy is to establish a standard for creation of strong passwords and the protection of those passwords.

Scope

The scope of this policy includes all personnel who have or are responsible for an account (or any form of access that supports or requires a password) on any system that resides at any Tuxis facility, has access to the Tuxis network, or stores any non-public Tuxis information.
