Hour 20. TCP/IP Security

What You'll Learn in This Hour:

• Encryption

• Certificates

• Securing TCP/IP

As you learned in the last hour, unauthorized users will go to great effort just to sneak onto other people's networks. The experts have been getting better at hiding TCP/IP communication so intruders can't learn secrets on the network. In this hour, you'll learn some of the important methods for securing TCP/IP.

At the completion of this hour, you'll be able to

• Define the terms encryption algorithm and encryption key

• Discuss symmetric and asymmetric encryption

• Describe digital signatures and digital certificates

• Describe the TCP/IP security protocol systems SSL and IPSec

• Explain what a virtual private network is and how it works

• Describe the Kerberos authentication process
