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]
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. [34]
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 ...
Key to the concept is that the participating basic service sets appear as a single network to the logical link control layer by using the same SSID. [ 18 ] [ 19 ] Thus, from the perspective of the logical link control layer, stations within an ESS may communicate with one another, and mobile stations may move transparently from one ...
The primary enhancement over WPA is the inclusion of the AES-CCMP algorithm as a mandatory feature. 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 ...
Netgear DG834G v3. The DG834 series are popular ADSL modem router products from Netgear.The devices can be directly connected to a phone line and establish an ADSL broadband Internet connection to an internet service provider (ISP) and share it among several computers via 802.3 Ethernet and (on many models) 802.11b/g wireless data links.
The BT Home Hub 2.0 was a combined wireless router and phone. It supports the 802.11b/g/n wireless networking standards, and the WEP and WPA security protocols. [9] It supports many of BT's services such as BT Fusion, BT Vision and BT Broadband Anywhere. It can also be used as a VOIP phone through BT Broadband Talk.
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.
