Secure Development Lifecycle
Set rules for secure software and system development to avoid costly production issues.
Plain language
This control is about making sure that the software and systems you develop are secure from the start. If you don't establish clear rules for secure development, you risk creating products that are vulnerable to cyber attacks, which can cause financial loss and damage to your reputation.

Official control statement
Rules for the secure development of software and systems shall be established and applied.
Why it matters
Insecure development practices embed vulnerabilities, leading to costly breaches or system failures that damage trust and incur financial losses.
Operational notes
Maintain secure coding standards and bake security into the SDLC (threat modelling, SAST/DAST, code review, dependency scanning) to find flaws early.
Implementation tips
- The IT manager should establish clear rules for secure development. This involves setting guidelines for how software and systems are built to prevent vulnerabilities. Using standards from ISO 27002:2022, they can ensure that developers separate testing and production environments and follow secure coding practices.
- The software development lead should integrate security checkpoints into the development cycle. This means including specific points in the project timeline where security is assessed, such as during design and before release. This ensures that any security issues are identified and fixed early.
- Security trainers should provide training for developers on secure development practices. They can organise sessions to teach developers about secure coding, the importance of testing for vulnerabilities, and keeping abreast of the latest security threats.
- The procurement team should ensure that any outsourced development follows your organisation's secure development rules. They need to verify this by obtaining documented assurances or certifications from suppliers.
- The IT security team should regularly perform security tests, such as code scans and penetration tests, to identify and rectify vulnerabilities. These tests should be scheduled after key development milestones as part of the software lifecycle management process.
