Governance as Code - https://www.cio.com/article/3277611/governance-as-code-keeping-pace-with-the-rate-of-change-in-the-cloud.html

"In the future, governance as code will be the backbone driving our IT systems and services. It will enable us to deliver consistent, efficient and highly repeating business outcomes at the lowest possible cost, with the maximum availability and security, while also allowing our people to expand into new and higher value-add roles across business."

IR Playbooks -

process of creating them (probably the hardest)

Implementation

Tabletop exercise (length, stakeholders, crafting a scenario to compare against)

What if an org has nothing? "We just blow up the environment and start over."

RTO/RPO metrics: How long can you survive as a company with an outage? How long does it take to get back online and operational? What's your appetite for the risk of that?

Lots of dependencies to creating

Tabletop discussion -

sponsors involved

Initiating condition

Threat modeling

Process steps

Best practices and local policies

End state - what is the goal? (eradicate infection, back to operating status)

Relation to governance/regulatory reqs. (do we have to report? What do we report? Fallout from incident, etc)
