Incorporating security by design is crucial in today's fast-moving software development process, where threat actors exploit complexity. By embedding security at every stage of application lifecycle, teams can proactively mitigate risks and ensure more secure, resilient software applications. Adopting a secure-by-design approach can reduce risk, prevent bottlenecks, and save up to 100 times more on fixing defects early on compared to later stages. Organizations should adopt tools that automatically scan code and open source dependencies for vulnerabilities while providing fast and actionable feedback to shift left and make security the default choice. Integrating security into requirements and design phases is key, with clear responsibilities, threat models, relevant standards, suitable security tools, and implementation of automated security controls being essential best practices. A secure-by-design approach can be achieved through developer-first security platforms like Snyk, which provides automated scanning, scoring, and remediation capabilities to address security threats early on without slowing development. Bridging the gap between security and development is critical for DevSecOps success.
