After completing this video, the learner will understand how to apply encryption technology to protect wireless network connections, including the differences between WEP, WPA and WPA2 encryption and the TKIP and CCMP protocols.
- [Voiceover] Network administrators may choose to add…encryption to wireless networks…to protect communications against eavesdropping.…Wireless encryption is a best practice for network security.…Encryption hides the true content of network traffic…from those without the decryption key.…It takes an insecure communication technology,…radio waves, and makes it secure.…You have four options when it comes to wireless encryption.…Two of them are bad.…First, using no encryption at all…and sending messages in the clear, open to anyone,…leaves everything on the network…vulnerable to eavesdropping.…
Second, using a technology…known as Wired Equivalent Privacy, or WEP,…uses a very weak encryption that is easy to hack.…I discuss attacks against WEP in the…Security Plus Threats and Vulnerabilities Course.…There are two options for wireless encryption…that are much better.…Wi-Fi Protected Access, or WPA,…uses the Temporal Key Integrity Protocol, or TKIP,…to add security that WEP didn't have.…TKIP changes the encryption key for each packet,…
