Summary

In this chapter, we looked into the two main wireless networking protocols that are used by embedded systems and how to attack them. Probing network activity is always very interesting and can point you toward some relevant security elements, such as keys and certificates that were identified during the S.T.R.I.D.E. exercise (Chapter 4, Approaching and Planning the Test). This is also a good starting point when your interactions with the system are limited because you cannot damage the system, or you only have a very limited number of test systems. In the next chapter, we will look into attacking other radio interfaces that can't easily be reached with common tools.
