POLICY:

All computer accounts must be password protected to help maintain the confidentiality and integrity of electronic data as well as to help protect the University's computing resources and infrastructure. This policy establishes a minimum standard for creation of strong passwords, the protection of those passwords, and the frequency of change.

 


STANDARDS:

Administrative Standards:

General

  • Passwords to university accounts and devices must be kept confidential. 
  • To preserve account integrity, the owner of the account should be the only person with knowledge of the password. 
  • No user is required to share a university account password with another individual; including but not limited to managers, co-workers, or technical staff.
  • Passwords that have been or suspected to have been compromised must be changed immediately.

UofL Network and/or Enterprise Software Accounts
(In addition to the general standard above, these standards apply to UofL network and enterprise software accounts)

  • Account holders should set up their challenge questions to facilitate self-service password resets (go to ULink).
  • Notification of password expiration will be provided to account holders 30 days in advance of the password expiration and three additional times: 15, five, and one day before expiration.
  • Passwords used for shared accounts should be changed immediately if compromised or when a holder transfers or leaves the university.
  • Passwords allowing for temporary access to production environments for problem resolution should be changed immediately following use.
  • Initial access passwords should be changed immediately upon login.
  • Passwords or pass phrases should be encrypted and not stored in clear text.

Technical Standards:

General

  • Passwords should expire every 90 days.
  • Passwords to systems containing sensitive information, including electronic Protected Health Information (ePHI) must expire no less often than every 90 days.
  • Passwords should be at least 8 positions in length.
  • Passwords to systems containing sensitive information, including ePHI must be at least 8 positions in length.
  • Strong passwords should be used. A strong password will include a combination of:
    • Alphabetic
    • Combination of both upper and lower case: A to Z and a to z
    • Numeric: 0 to 9
    • Special Characters such as: ~!@#$%^*( )+=[ ] { } ?, etc.  Please Note: The special characters not allowed are  > < ; and &
  • Passwords to systems containing sensitive information, including ePHI, must require at least three or the four criteria specified immediately above.
  • Passwords should not consist solely of personal information or words found in a dictionary (any language). Ideally, this information should not be used. If used, the use of at least two of the three types of strong password characters noted above as part of the password is required.
  • Password use and security can be facilitated using the password hint web site. For more information go to ULink and see the "Password Self Service" section.
  • Password history must be securely maintained and passwords not repeated for a period of 24 months or equivalent iterations.
  • Access accounts will be locked after 6 consecutive unsuccessful login attempts.

UofL Network and/or Enterprise Software Accounts
(In addition to the general standards above, these standards apply to UofL network and enterprise software accounts)

  • Expiring passwords should be used for privileged accounts wherever feasible.
  • Passwords (individual and shared accounts) should expire every 90 days and meet the sensitive information complexity requirements.
  • Software that is unable to comply with the minimal password standards must establish compensating controls to maintain equivalent protection.

In the event that significant regulatory changes occur, this policy will be reviewed and updated as needed per the policy management process.
