How to Update your Incident Response Playbook During a Crisis

Speak With A Security Expert Now

As we (perhaps uncomfortably?) settle into the “new work from home normal” (or as I like to call it a Modified Disaster Recovery situation), it’s likely a good time to update your Incident Response Playbook as new cybersecurity threats come to light almost daily in the current environment. But first, we must ensure that we understand what incident response is.

What is Incident Response?

The term incident response refers to the operating procedure an organization uses to deal with cyberattack or other breaches in data. The Incident Response process has become a necessity with what seems to be an unavoidable issue as companies move more and more to the digital world. How the incident is managed, who will be involved in the recovery process, and ensuring that any collateral damage is kept to a minimum are all important to include when considering an Incident Response plan.

What is an Incident Response Plan?

Here are a few things a standard Incident Response Plan template would include:

Now that you understand what incident response is, it’s imperative you have an incident response plan in place.

Don’t have an Incident Response Playbook? Start by reviewing this resource NOW:

How Often Should An Incident Response Plan Be Reviewed?

I typically recommend a complete review of your Incident Response Playbook on an annual basis (with a likely scenario tabletop test every quarter). An annual refresh helps account for significant changes such as new staff, upgraded skills, new partners/vendors or technology.

What’s Most Important in the Incident Response Playbook?

The preparation column is among the most important facets of the Incident Response Playbook. Just as an ounce of prevention is worth a pound of cure, you’ll find that the better-prepared you are for the eventual incident, the better you’ll emerge from it.

Incident Response Plan Considerations

Let’s get started with specifics to consider in these unusual times:

Ensure You Have an Incident Response Playbook

The first priority within any incident response plan is to ensure the safety of your staff. The best way to do this is to be prepared for the security challenges moving ahead. I hope that you’ll take this time to review your Incident Response plans and update with the key points I’ve listed above. If you work with an incident response vendor, proactively reach out now to assist you with this before an incident occurs.
