Mastering™ Network Security, Second Edition

4.4. Summary

We've covered a lot of ground in this chapter. We discussed the basics of communication properties and looked at transmission media and hardware from a security perspective. We also discussed what traffic control options are available with typical network hardware.

In the next few chapters, we'll look at systems that are specifically designed to implement security policies. We will start by discussing firewalls and then work our way into intrusion detection systems.
