What is getting back to basics - IR 101

  • This will likely be multiple episodes

  • We will start with Windows

Why is this important?

  1. WHEN you have an incident, data we, and you need will be available

  2. This is probably the #1 finding and recommendation we have made to organizations we have been involved with over the years

  3. Security tools fail, so other data you collect can help discover what happened where, when, and how

What is the problem we are wanting our listeners to solve? 

  1. To be better prepared in the event of an incident to speed up investigations

  2. Give your SOC, IT, or Security people the data they need to investigate events

  3. Make log management data better if you are collecting all the things

  4. And of course… help your IR Consultancy do a better job FASTER
