Password Policy (revised 10/2011) Passwords are an important aspect of computer security. They are the front line of protection for user accounts. A poorly constructed password may result in the compromise of an e-mail or computer access account or even the entire TSU network. All TSU students, employees, contractors, and vendors with access to TSU computer and network systems are responsible for taking the appropriate steps, as outlined in this policy to select and secure their passwords. This password policy will apply to the following systems: the TSU network, TSU wireless network, myTSU, Exchange e-mail, TSU website accounts, screen saver protection, SciQuest purchasing system, eLearn (D2L) system, and INB Banner, and any other computing or network resource used on the TSU campus. The strong password policy may not be enforced on all systems simultaneously but as time and platform specific strong password policies can be applied. This policy establishes the requirements for creating strong passwords, the protection and management of passwords, the frequency passwords are to be changed, and password privacy. Creation of Strong Passwords The use of strong passwords is necessary to thwart would be computer hackers attempting to guess your password using what are known as password crack programs. Strong password construction criteria at TSU is: Must be at least eight (8) characters in length Must contain at least 1 uppercase letter (AZ) Must contain at least 1 lowercase letter (a-z) Must contain at least 1 or more numbers (0-9) Additionally, the construction of passwords should not: Include a word in any language, slang, dialect, jargon, etc. Be based on personal information, names of family, birthdates, etc. Password Management and Protection Passwords must not be inserted into email messages or other forms of electronic communication. Do not use the same password for TSU accounts as for other non-TSU access (e.g., personal ISP account, option trading, benefits, etc.). Do not share TSU passwords with anyone, including administrative assistants or secretaries. All passwords are to be treated as sensitive, Confidential TSU information Passwords should never be written down or stored on-line Do not reveal a password over the phone to ANYONE Do not reveal a password in an email message Do not reveal a password to your boss Do not talk about a password in front of others Do not hint at the format of a password (e.g., "my family name") Do not reveal a password on questionnaires or security forms Do not share a password with family members Do not reveal a password to co-workers while on vacation Do not use the "Remember Password" feature of applications (e.g. Outlook) that remembers your password when the username is entered. Do not write passwords down and store passwords anywhere in your office Do not store passwords in a file on ANY computer system including mobile devices without encryption Change passwords at least once every six months Password Reset Frequency Users will be forced on some systems to reset passwords every 90-180 six months. As a general rule, users should reset their passwords at least every 90 day. Password privacy If a password compromise is suspected, report the incident to CIT and change all passwords. No one should every demand your password including CIT staff. If your account has issues that require CIT to login, the password will be reset with your knowledge and once the work is completed, you will be requested to reset the password to one of your choosing. General Password Construction Guidelines Weak passwords have the following characteristics: Contains less than eight characters Forms a word found in a dictionary (English or foreign) or is a common usage word such as: Names of family, pets, friends, co-workers, fantasy characters, etc. Computer terms and names, commands, sites, companies, hardware, software.

Word or number patterns like aaabbb, qwerty, zyxwvuts, 123321 Uses any of the words referenced above spelled backwards Uses any of the above preceded or followed by a single numeric digit (e.g., secret1, 1secret) Strong passwords have the following characteristics: Contain both upper and lower case characters (e.g., a-z, A-Z) Have digits and punctuation characters as well as letters e.g., 0-9, !@#$%^&*()_+|~- =\`{}[]:";'<>?,./) Are at least eight alphanumeric characters long.
