Training and Testing Plans

Incident response plans require regular training and testing to ensure procedures are accurate and personnel know their roles. Testing methods range from tabletop exercises to parallel environment simulations and live environment validation.

About this video

A well-documented incident response plan only delivers value if the people responsible for executing it understand their roles and the procedures themselves hold up under realistic conditions. Training and testing are the mechanisms that close the gap between a plan on paper and an effective response in practice. Through regular exercises, organizations can identify steps that are unclear, out of sequence, or simply ineffective, then make targeted improvements before an actual incident occurs. Several testing approaches exist, each suited to different organizational needs and risk tolerances. Tabletop and walkthrough exercises bring all relevant stakeholders together to review and discuss procedures in a structured setting, often using a simulated scenario such as a data exfiltration event to drive the conversation. For organizations with technical systems involved in their response procedures, parallel processing offers a lower-risk alternative—running tests against staging, development, or virtual environments rather than production infrastructure. When the highest degree of realism is required, live environment testing can be conducted, an approach particularly relevant in disaster recovery contexts. Selecting the right combination of these methods ensures both the plan and the people executing it are prepared when it matters most.

Transcript

Anytime we have a plan, we're going to want to carry out some training and testing on that plan — making sure that people that are going to carry out this plan know what it is that they need to be doing, and then also testing the plans to make sure that they're correct, and testing the people.

Why We Test

Training and testing is an important part of preparing for our incidents. That is, we're going to want to test out our plans and make sure that they're accurate and that people know what to do with them. What we may find in this process is that there are certain steps that just don't work very well. So we can start moving things around and putting them in different orders, or figuring out what is the best approach to this.

Ways to Test a Plan

There are several different ways we can approach testing out our plan. For instance, we could do just a tabletop or walkthrough exercise. That is, we get everyone involved that needs to go through this process. We sit them down at a table and then we walk through the procedures to make sure that they're accurate, to make sure that nothing needs to be adjusted. We may even set up some sort of simulation — let's say it's data exfiltration, somebody's stealing data. How are we going to approach our procedures here and walk through those procedures?

Or what we could do is we could do some sort of parallel processing. Maybe there's some systems that are involved, and so rather than using the production system, instead we're going to use the staging system or the developer system. Or maybe it's a virtual environment — we're going to set up some sort of virtual setup here and we're going to test it out, test our processes and procedures, and maybe use some sort of simulation in that.

Or what we could do is we could do it with our live environment. So some of these have a little more to do with maybe if you're doing disaster recovery.
