Building Security Into the SDLC From Day One
Security bolted on at the end is expensive and brittle. Here's how to weave it through the development lifecycle instead.
The most expensive security bugs are the ones found in an audit, months after they shipped. Building security into the development lifecycle catches them when they're cheap to fix — at design and commit time.
Threat model at design time
Before writing code, ask how the feature could be abused. A lightweight threat model surfaces the risks worth designing against.
Shift security left in CI
Run dependency scanning, secret detection and static analysis on every pull request. Make security feedback as fast as test feedback.
Least privilege everywhere
Default to the minimum access required. Scope tokens narrowly, rotate secrets and keep humans out of production credentials.
Make compliance a byproduct
If your controls are real and continuous, SOC 2 and ISO 27001 evidence largely produces itself. Compliance should reflect good practice, not replace it.
Security done early is cheaper, calmer and far more effective than a frantic pre-launch scramble.
