More About Security

This chapter just barely scratched the surface of what there is to know and do about network security. There are lots of great books on the topic, and I've mentioned several of them in this chapter.

You also can get lots of information on the Web. First, www.sans.org and www.cert.org are great places to start looking into the security community. Steve Gibson has plenty to say about security at www.grc.comit's educational and entertaining.

Finally, you might look into additional measures you can take to protect your computer and your network. There are many ways to configure networks. It's common, for example, to keep any public Web or email servers you have separate from the rest of your LAN. For additional security, you even can buy or build special-purpose firewall routers to place between your LAN and the Internet. One nifty way to do this is shown at www.linux-firewall-tools.com/linux/.

In any case, I'm glad you're interested enough in security to have read this far down in the chapter!
