Chapter 15. Wireless Attacks

In this chapter we’ll take a brief look at wireless security. So far we’ve looked at several ways to breach the security perimeter. But web application security, firewalls, security-awareness training, and so on can do nothing to protect an internal network if there’s an attacker sitting on a bench in front of the target organization’s building and the organization provides wireless access with weak encryption to the internal network.

Setting Up

For the examples in this chapter, I’ll be using a Linksys WRT54G2 wireless router, but any router that supports WEP and WPA2 encryption will work. By default, my Linksys router has a web administration interface at http://192.168.20.1, as shown in Figure 15-1. The default username ...

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
