Apply Secure Design Principles in Application Architectures

The general rules for secure development work have been drawn up and approved by the development managers. The implementation of the rules is monitored in software development in the organization and the rules are reviewed at least yearly.

The safe development policy may include e.g. the following things:

• safety requirements of the development environment
• instructions for secure coding of the programming languages used
• safety requirements at the design stage of properties or projects
• secure software repositories
• version control security requirements
• the skills required from developers to avoid, discover and fix vulnerabilities
• compliance with secure coding standards

Compliance with the rules of secure development may also be required of key partners.

The organization must create procedures that by default cyber security and security requirements are considered from the start when developing and designing new systems, digital services or business processes.

This is called the principle of built-in and default security (security by design). As a result of this approach, the design documentation should clearly indicate what measures are taken to ensure cyber security.
