Special attention should be paid to the use of strong passwords. Cisco LEAP is a password-based algorithm. To minimize the possibility of a successful dictionary attack, use strong passwords, which are difficult to guess. Some characteristics of strong passwords include:

A minimum of ten characters
A mixture of uppercase and lowercase letters
At least one numeric character or one non-alphanumeric character (example: !#@$%)
No form of the user's name or user ID
A word that is not found in the dictionary (domestic or foreign)
