Each of the protocols covered in this chapter plays an important role in securing transmissions between remote locations. Its important to have the big picture in mind regarding how these protocols interact with each other in various parts of the system when troubleshooting connectivity and security issues.

In this project, you will synthesize the major characteristics of each protocol into a single reference table. You can create Table 7-1 below in a word-processing program or a spreadsheet program. Then refer to the information given in this chapter to fill in the missing pieces.
