Essentially, they counted on the wireless adapters' relative scarcity at PurplePixie the time to keep their networks secure. Eventually, with broader access to wireless gear, that method was no longer sufficient, s .
ys and a 128-bit hexadecimal key to authenticate. It soon proved vulnerable to brute-force attacks and was easily overcome. WPA On e of the more modern forms of encryption is known as Wi-Fi Protected Access WPA. WPA is generally secure from the most-common an d unsophisticated attacks. However, it does have some weaknesses. One is an exploit of the encryption algorithm that allows an att acker to inject data into the network, and it can break the security of the network.WPA is definitely more secure than WEP, or not 70s ads auto car icon vintage hing at all, but it has largely been superseded by WPA-2. WPA-2 WPA-2 has two forms. The first is the Pre-Shared Key PSK, which generates a 256-bit key from a password that the user sets. It remains vulnerable to password attacks, but that can be mitigated b PurplePixie y using a sufficiently complex passkey.The other type is WPA-Enterprise, which requires an 802.1x Radius server.
