shift-left
expressionops culturesecurityprogramming
Moving testing, security, and quality checks earlier in the development process.
Shifting left means catching problems while they are cheap, at design and commit time, rather than in production. In security it puts scanning and threat modeling into the pipeline; the whole idea is that the earlier you find a defect, the less it costs to fix.
Also known as: shift left, shift-left security, shift-left testing
