Choosing a strong password is essential to keeping your system safe. There are a couple general principles to help
you avoid your password being compromised. The longer the password, the harder it will be to crack it with brute
force. For example, if you have a three-digit password that is only made up of numbers, then it can be cracked in
under 1,000 tries. If the number of digits is longer, obviously, it will take more tries to crack. The same principle
applies to the characters you use. To make your password strong, use different types of characters. Use numbers,
letters of both upper- and lowercase, and punctuation. This greatly increases the number of tries it takes to crack a
password by brute force.
Hackers are aware of these strategies, however, and try to skew the odds in their favor by using dictionaries of
common passwords and variations on them to reduce the number of tries needed. To thwart this type of attack,
avoid proper nouns and words that can be found in the dictionary. A common technique is to use the first letter of
each word of a phrase to allow for a combination of letters not common in any language.
