Walking Through Applied Network Security Monitoring – Forward through Chapter 1

Back in December, it really doesn’t feel that long ago, I talked about how I was prepping for a project.

The end goal is to brush up on Network Security Monitoring (NSM) and use it to better monitor my home network. I occasionally check the logs but think I would be more active if I had a centralized tool to help.

If you want in-depth/exact definitions from my sources, for FAIR, lookup: Measuring and Managing Information’s Risk, The Open Group’s Open FAIR Risk Taxonomy and Risk Analysis whitepapers, the RiskLens FAIR study guide (provided as part of the course). For Threat Intelligence, lookup: Effective Threat Intelligence, and Intelligence Analysis 6th edition.
