Understand and Support Secured Protocols
So once again I'm going to try to send you some data and I want this data to be confidential. Well we now understand asymmetrical and symmetrical encryption and the different things that we can use, but I'm going to send this in a message across TCP/IP, that's the main protocol of communication that we're using. I need a protocol on top of that, that can use those security features of asymmetrical and symmetrical. So we have protocols that you've probably actually heard quite a bit about these from using them, that allow us to do secured kinds of communication. And so we're going to take a, just a brief look at IPSec, what it is, what it's used for. And really this is something that you probably are already using today. Also we want to look at SSL, I know if you're purchased anything off the Internet, you've gone to a secured website, you've signed into a secured website, you've already been using SSL. But we're going to add something else to it that not a lot of people are aware of, something called TLS or transport layer security. It's a little bit different. Now I know I mentioned this earlier, but I want to give you some more notes on digital signatures and the protocol of secured mime. And so what do you say we go ahead and dive right in with IPSec and how we're going to use it.
