list of things that we need to do in the bathroom. Or you might not go room by room, but instead break it into different aspect. Here's all the electrical stuff that we need to do, here's the plumbing work that we need, the cosmetic list versus these structural alterations, here's the ongoing maintenance tasks, and so on, and so on. And however you choose to categorize tasks, there's always some crossover in dependencies, but still, breaking them into different areas of focus make it easier to think about, plan for, and achieve, and it's the same here. So while there are many different ways that you can organize the elements of security, we're going to break it into six areas, and we'll go over each one to explore what value it brings to the business, or, in many cases, what value it protects. We'll begin by looking at the security of various products we build and use, and this includes software applications and infrastructure. We'll then shift our focus to access management, controlling who can get to our systems and what they're allowed to do. After that, we'll cover specific issues for securing our data and ever increasing focus for almost all organizations. That will lead us to governance, where we'll also touch on risk management and compliance. Understanding those first four will help us in exploring security operations, which includes secure administration. Finally is cyber intelligence and testin, a key component of a mature cyber defense and a distinct important element for your overall security plan. So let's get started.
