The WPS push button (center, blue) on a wireless router showing the symbol defined by the Wi-Fi Alliance for this function. Wi-Fi Protected Setup (WPS), originally Wi-Fi Simple Config, is a network security standard to create a secure wireless home network.
WPA-Personal and WPA2-Personal remain vulnerable to password cracking attacks if users rely on a weak password or passphrase. WPA passphrase hashes are seeded from the SSID name and its length; rainbow tables exist for the top 1,000 network SSIDs and a multitude of common passwords, requiring only a quick lookup to speed up cracking WPA-PSK.

Your communications are not protected. Yellow means PRIVATE WiFi is starting up. Green means that PRIVATE WiFi is activated. Your internet connection is encrypted and secure. Blue means PRIVATE WiFi is not activated because you are accessing a secure (WPA, WPA2 or wired) connection. Your internet connection is secure.
The most common solution is wireless traffic encryption. Modern access points come with built-in encryption. The first generation encryption scheme, WEP, proved easy to crack; the second and third generation schemes, WPA and WPA2, are considered secure [7] if a strong enough password or passphrase is used.
Temporal Key Integrity Protocol (TKIP / t iː ˈ k ɪ p /) is a security protocol used in the IEEE 802.11 wireless networking standard. TKIP was designed by the IEEE 802.11i task group and the Wi-Fi Alliance as an interim solution to replace WEP without requiring the replacement of legacy hardware.
FreeBSD 7.0 introduced full support for WPA and WPA2, although in some cases this is driver dependent. FreeBSD comes with drivers for many wireless cards and chipsets, including those made by Atheros , Intel Centrino , Ralink , Cisco , D-link , and Netgear , and provides support for others through the ports collection .
One particular attack is always possible against keys, the brute force key space search attack. A sufficiently long, randomly chosen, key can resist any practical brute force attack, though not in principle if an attacker has sufficient computational power (see password strength and password cracking for more discussion). Unavoidably, however ...
Experts say vehicle-based attacks are simple for a 'lone wolf' terrorist to plan and execute, and challenging for authorities to prevent.
