RADIUS servers that support LEAP include the following:
Cisco Secure ACS version 2.6 and later
Cisco Access Registrar version 1.7 and later
Funk Software's Steel-Belted RADIUS version 3.0 and later
Before implementing a LEAP solution, network administrators are advised to review the 802.11 Wireless LAN Security White Paper. 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 the following:
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).
