INFORMATION SECURITY - STRONG PASSWORDS


Select a password that you can remember easily, but which will be as difficult as possible for anyone to guess. Do not share your password, and do not write it down. Your password should be at least 8 characters in length for maximum safety against brute force attempts to guess your password.

Some computer systems treat uppercase and lowercase letters as unique characters, and will allow you to combine them together into your password. In addition to punctuation characters in your password. Combining all of these together further increases the security of your password, making it harder to guess, and harder to crack by people who are trying to steal your password.

Good Passwords Can Be Created By
using at least one symbol or number (preferably not just one at the end, nor one at the beginning)
using a varying combination of lower and upper case letters (i.e. IsDlMs)
using at least 8 letters or symbols; hackers try short words first
using two words that normally don't go together that are separated by a punctuation mark or number. For example, 'star6tan' would be difficult to guess
using the first letters of a phrase you can remember: "I sure do love my spouse!!" becomes the difficult to crack "Isdlms!!"

Passwords Should
not be an alphabetic series either forwards or backwards (i.e., ABCDEF or FEDCBA)
not be a numeric series, either forwards or backwards (i.e., 123456 or 654321)
not be a string of all identical letters or numbers (i.e., AAAAAA or 111111)
not be a common keyboard shortcut (i.e., ASDFG or QWERTY)
not be an easily guessed word such as your name, userid, PID, or any variation thereof (backwards, changing case, etc.)
not be a word(s) referring to anything noticeable about you, such as the name of your spouse, child, pet, favorite football team, or literary character
not be a word that appears in a dictionary

Password Security Can Be Maintained By
using different passwords on each account you have
changing your passwords at regular intervals
never writing your passwords down
never sharing your password with others

One Good Example: Using a Phrase
One way to choose a password is to make up a sentence and use the first letter of each word as a letter in your password. (this is sometimes referred to as a mnemonic phrase)
For example, you might find it easy to remember: Orange elephants invade Alaska; film at eleven. Taking the first letter of each word, your password would be OeiAfae.

Using both upper- and lower-case letters, as well as numeric digits and special characters makes the password more difficult to guess, so a variation such as OeiA;f@11 is better.
Note: Don’t use these examples as your password.

It is common for web sites to ask web surfers for an ID and a password. Please use a password different from your OLLU passwords to prevent outsiders from gaining access to OLLU systems. People can easily figure out where you work or study by looking at your e-mail address in any mail you send over the Internet. You may find it helpful to think in terms of two kinds of passwords: your “outside” password for use at remote web sites and your “inside” password on OLLU systems.
