Wireless Networks: Background

"we're not using wires anymore" -- IEEE 802.11 security measures:

• First try: Wired Equivalent Privacy (WEP)

  weak link level encryption - broken; deters naive attackers

• Second try: WiFi Protected Access (WPA)

  Flexible and complex - better on paper; "constantly improving"; support varies (supported in OpenBSD 4.4 onwards)

MAC address filtering: not really useful, but if you want to, see brconfig

- > you need SSH & SSL
