Join Mike Chapple for an in-depth discussion in this video WEP, WPA, and WPA2, part of CompTIA Security+ (SY0-501) Cert Prep: 2 Technologies and Tools.
- [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,…radiowaves, 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 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.…
