Network administrators may choose to add encryption to wireless networks to protect communications against eavesdropping. In this video, learn 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.
- [Instructor] 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.…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,…preventing an attacker from discovering the key…after monitoring the network for a long period of time.…
