Over at the new blog American Partisan, Kit Perez (co-author of Basics of Resistance) has been posting about critical information analysis.
This is a subject we touched on in the book: how to determine what resistance information you hold is critical, what the likely threats are, and how to protect the info.
As she explains in part I, your personal information can be highly critical — for instance, what supplies you have stored up or even (in some cases) the names and ages of your children.
In part II she gets into analyzing the threats.
These and the installments to come are musts for anyone who wants a deeper dive into personal or organizational OPSEC.
