Password Standard

1.0 Overview

Password guessing, or “cracking”, is often automated given the ubiquity of inexpensive fast computing resources that can be combined with well-known attack methods or malicious software. Highly motivated criminals are constantly using automated processes to probe systems for accounts that have weak passwords or account lock-out mechanisms. In some situations, criminals may store compromised passwords for long periods. Poorly chosen passwords or management can lead to system and data compromise, which, in turn can have undesired consequences for UT Arlington.

2.0 Objective / Purpose

This document describes the minimum acceptable standards for password construction and management in order to greatly reduce the risks that may lead to password compromise. The standards established in this document are derived from best-practices and are intended to conform to, and be consistent with, requirements in UTS 165 and the U. T. System Identity Management Federation Member Operating Practices (MOP).  

3.0 Scope

The requirements in this standard apply to passwords assigned to any account created on any University owned or controlled information resource. This includes, but is not limited to:

  • UT Arlington NetID
  • All non-centrally managed local user.
  • All accounts that have system-wide privilege (e.g. administrator or root, or equivalent accounts).
  • All service accounts.
  • All database accounts.
