While some wireless networks are meant for open access by anyone who wishes to use them, most wireless networks limit access to authorized users. There are three primary mechanisms to authenticate the users of a wireless network: preshared keys, enterprise authentication and captive portals. Learn how to secure wireless networks, including the use of preshared keys and enterprise authentication, EAP, PEAP and LEAP authentication and captive portals.
- [Narrator] While some wireless networks are meant…for open access by anyone who wishes to use them,…most wireless networks limit access to authorized users.…There are three primary mechanisms to authenticate…the users of a wireless network: preshared keys,…enterprise authentication, and captive portals.…Preshared keys are the simplest kind…of wireless authentication, and are commonly…used on home Wi-Fi networks.…In the preshared key approach, the network…uses a 256-bit encryption key to control access.…
Whenever a user wishes to connect a device to the network,…he or she must enter the preshared key on the device.…The preshared key may be entered directly, as a 64 character…hexadecimal string, but that's a pretty unwieldy approach.…Instead, most networks use preshared keys…that ask users to enter a password,…consisting of between 8 and 13 ASCII characters.…The network then uses the PBKDF2 key stretching function…to convert that ASCII password into…a 256-bit network encryption key.…
I discussed the PBKDF2 function…
