Course description

You understand TCP/IP and you’re making it work, and now it’s time to make sure it’s secure while it’s working. In this course, you’ll explore the fundamentals of TCP/IP security: symmetric and asymmetric encryption, cryptographic hashes, access control, single sign-on and more. You’ll look at certificates and trust (including certificate error scenarios) and familiarize yourself with the guard dog program for wired networks, Kerberos.
