Part of Wireless Network Hacks and Mods For Dummies Cheat Sheet

The convenience of wireless networks is also the greatest risk to security. Wireless networks can’t be contained inside your office or house like a wired network, so they’re more vulnerable to a network breach. Security measures, however, make it much harder to do anything with those signals, or compromise your network. Check out this list of security standards for Wi-Fi networks:

Security Type Infrastructure Requirements Security Level
WEP WEP-compatible AP and network adapters Low, easily cracked by active or passive attacks
WPA (PSK) WPA-compatible AP and network adapters High, vulnerable to password cracking (dictionary) attacks
WPA Enterprise WPA Enterprise-compatible AP and network adapters, RADIUS
server
Very high
WPA2 (PSK and Enterprise) WPA2-compatible AP, network adapter (RADIUS for
Enterprise)
Extremely high; adds AES (Advanced Encryption System), which
could take millions of years to crack with current technology
