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.
As of May 2013, 44.3 percent of all wireless networks surveyed by WiGLE use WPA or WPA2. [14] MAC address authentication in combination with discretionary DHCP server settings allow a user to set up an "allowed MAC address" list. Under this type of security, the access point will only give an IP Address to computers whose MAC address is on the ...
WPS is a wireless method that is used to connect certain Wi-Fi devices such as printers and security cameras to the Wi-Fi network without using any password. In addition, there is another way to connect called WPS Pin that is used by some devices to connect to the wireless network. [ 1 ]
The performance of USB hard drives attached to an AirPort Extreme is slower than if the drive were connected directly to a computer. This is due to the processor speed on the AirPort Extreme. Depending on the setup and types of reads and writes, performance ranges from 0.5 to 17.5 MB/s for writing and 1.9 to 25.6 MB/s for reading. [ 8 ]
Aircrack-ng is a network software suite consisting of a detector, packet sniffer, WEP and WPA/WPA2-PSK cracker and analysis tool for 802.11 wireless LANs.It works with any wireless network interface controller whose driver supports raw monitoring mode and can sniff 802.11a, 802.11b and 802.11g traffic.
Connections between "clients" are made using MAC addresses. All base stations in a wireless distribution system must be configured to use the same radio channel, method of encryption (none, WEP, WPA or WPA2) and the same encryption keys. They may be configured to different service set identifiers (SSIDs). WDS also requires every base station to ...
In order to mount a brute-force or dictionary based WPA password cracking attack on a Wi‑Fi user with WPA or WPA2 enabled, a hacker must first sniff the WPA 4-way handshake. This sequence can be elicited by first forcing the user offline with the deauthentication attack.
Wireless security is another aspect of computer security. Organizations may be particularly vulnerable to security breaches [6] caused by rogue access points.. If an employee adds a wireless interface to an unsecured port of a system, they may create a breach in network security that would allow access to confidential materials.
