Appendix A. Security Handbook

This last chapter of the book is a reference guide, which can provide a single place for you to find highly critical information. Much of the information scattered throughout the previous chapters is compiled here. Each section is laid out with highly valuable information presented in a format for reference and use, and not written to be a tutorial. Each section can be consumed quickly and easily.

While this format differs slightly from the rest of the book, the information is very valuable. I encourage you to read this once to fix in your mind these contents.
