Mindset shift to a DevSecOps culture
By: Buck Hodges
Security is a key part of DevOps. Buck Hodges first walks through how we have done our security war games with red teams and blue teams. Buck goes on to cover our best practices for DevSecOps in running a SaaS business.
"Fundamentally, if somebody wants to get in, they're getting in..accept that. What we tell clients is: number one, you're in the fight, whether you thought you were or not. Number two, you almost certainly are penetrated." - Michael Hayden, Former Director of NSA and CIA
The Mindset Shift
The Mindset Shift to a DevSecOps culture included an important thinking about not only preventing breaches, but assuming breaches as well.
Security strategy components
|Preventing breaches||Assuming breaches|
|Threat models||War game exercises|
|Code reviews||Central security monitors|
|Security testing||Live site penetration tests|
|Security development lifecycle (SDL)|
Both strategies are important, and the items in the preventing breaches mindset are great but we have found that they just aren't enough.
Assuming breaches helps answer some important questions in security (so they don't have to be answered in an emergency):
- How will I detect an attack?
- What am I going to do if there is an attack or penetration?
- How am I going to recover from the attack? (e.g. data leaking or tampering)
