WiFi technologies may introduce security concerns of their own. In this video, learn about various attacks against WiFi Protected Access, or WPA, and WiFi Protected Setup, or WPS.
- [Instructor] In the previous video,…you learned how attackers can easily defeat…WEP encryption on wireless networks.…In this video, let's take a look how new attack techniques…threaten to undermine the security…of newer encryption technologies.…Recall that there are four ways…to protect traffic on a wireless network.…We've already discussed how two…of those are woefully inadequate.…Running unencrypted wireless networks leaves…communications open for anyone to intercept.…And using Wired Equivalent Privacy, or WEP,…provides a false sense of security…because it is easily hacked.…
Let's talk a little more about WiFi…Protected Access, or WPA.…WPA, like WEP, relies upon the RC4 encryption standard.…If you recall, the problem with WEP…is that hackers monitoring the network…for a long period of time can gather enough…clear text information to determine…the encryption key, which never changes.…WPA adds a new twist to WEP,…the Temporal Key Integrity Protocol, or TKIP.…That's just a fancy way of saying…that the encryption key changes all of the time.…
