The need for wireless security
- [Instructor] Let's consider the need for wireless security. As a metaphor, ask yourself, would you consider putting an Ethernet jack from your network in the parking lot of your building? Of course not, that's not secure. However, if we don't properly secure our wireless networks, then their signals extend outside of our building. That's essentially what we're doing. So we clearly need to secure our wireless networks. But what does that mean exactly? Well, there are two primary things that we want to achieve with wireless security. The first is authentication. We want to make sure that someone connecting to our network has appropriate credentials to do so. And if anyone were to intercept that wireless communication, we don't want them to be able to interpret the data. The way we accomplish that is through encryption, which scrambles up the data, making it unreadable to anyone other than the intended recipient. And over the next few videos, we're going to be taking a look at the history of wireless network security, and see what the best options are today for securing our wireless networks.
