Secure by Default: Lock down your development for better AppSec

This piece examines the Secure by Default approach—closely linked to Secure by Design—as a proactive, prescriptive method to embed security into software and platforms, guiding developers through guardrails and paved paths while minimizing configuration risks. Experts highlight key attributes (invisibility, extensibility, and thoughtful migration), practical examples (SAST in pipelines, deny-by-default controls, automatic patching), and the need for vendors to assume greater responsibility rather than offloading hardening to customers. While potential benefits extend to platform engineering and developer cognitive load reduction, the article underscores hurdles such as unclear standards, market incentives, regulatory pressures, varying threat models across use cases, and difficulties applying these principles to legacy systems.
