2. Wi-Fi Protected Access - Wikipedia

   en.wikipedia.org/wiki/Wi-Fi_Protected_Access

   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.

   A major security flaw was revealed in December 2011 that affects wireless routers with the WPS PIN feature, which most recent models have enabled by default. The flaw allows a remote attacker to recover the WPS PIN in a few hours with a brute-force attack and, with the WPS PIN, the network's WPA/WPA2 pre-shared key (PSK). [3]

   Both WPA and WPA2 support EAP authentication methods using RADIUS servers and preshared key (PSK). The number of WPA and WPA2 networks are increasing, while the number of WEP networks are decreasing, [34] because of the security vulnerabilities in WEP. WPA2 has been found to have at least one security vulnerability, nicknamed Hole196.

5. Pre-shared key - Wikipedia

   en.wikipedia.org/wiki/Pre-shared_key

   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, pre-shared keys are held by both parties to the communication, and so can be compromised at one ...

6. Wireless access point - Wikipedia

   en.wikipedia.org/wiki/Wireless_access_point

   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. Some APs support hotspot style authentication using RADIUS and other authentication servers. Opinions about wireless network security vary widely.

7. Wi-Fi - Wikipedia

   Wi-Fi Protected Access 2 (WPA2) ratified in 2004 is considered secure, provided a strong passphrase is used. The 2003 version of WPA has not been considered secure since it was superseded by WPA2 in 2004. In 2018, WPA3 was announced as a replacement for WPA2, increasing security; [147] it rolled out on 26 June. [148]
