Chapter 26. Exploring Security in Depth
In the physical world, security is the freedom from danger. There are myriad dangers in the physical world, but in the world of Excel, dangers relate to protecting data (absent an army of spreadsheet-driven killer robots). Specifically, Excel security is designed to protect you from:
Unauthorized or accidental changes
Malicious changes or destruction of data
Theft or unauthorized distribution of restricted information
Attack from viruses
This chapter explains approaches to protecting your data from these threats and explains how to implement those approaches within Excel.
