Secure engineering involves applying security measures throughout the development of IT projects to mitigate various threats.
What are Secure System Engineering Principles? 🤔
Secure System Engineering Principles involve integrating security measures throughout the system development lifecycle to ensure that information systems are protected against both current and potential threats. These principles emphasize the importance of designing, developing, and maintaining systems in a way that embeds security from the start, rather than as an afterthought.
Relation to ISO 27001:2022
ISO 27001:2022, specifically Annex A 8.27, emphasizes the necessity of adopting secure system architecture and engineering principles. This annex helps organizations protect their information systems through the entire lifecycle — from design and development to deployment and operation. It advocates for secure design practices, which ensure that the systems are inherently robust against security threats.
Key Areas of Focus
System Architecture and Design: Ensuring that the architecture and design of systems integrate security considerations from the outset.
Authentication and Access Control: Developing robust methods for user authentication and secure session control.
Data Protection: Implementing procedures for sanitizing and validating data to prevent unauthorized access and ensure data integrity.
Secure Coding Practices: Adopting secure coding guidelines to minimize vulnerabilities and prevent security breaches.
Change Management: Managing changes to systems and applications securely to prevent security lapses.
Security Testing and Audits: Conducting thorough testing and audits to identify and mitigate potential security vulnerabilities.
How to Implement Them
Risk Assessment and Management: Start by assessing potential risks and vulnerabilities early in the system development process. This involves identifying and documenting the security requirements based on the assessed risks.
Integration into Development Lifecycle: Integrate security practices into each phase of the system development lifecycle, ensuring that security checks and balances are considered at each stage.
Training and Awareness: Educate and train developers and engineers on secure coding practices and the importance of security in the development process. Snyk’s Secure SDLC provides insights into integrating security into the development process and can serve as a resource for ongoing learning.
Secure Development Environments: Set up and maintain secure development environments that limit access to unauthorized users and ensure that security tools are integrated into the development tools.
Continuous Monitoring and Improvement: Implement a process for continuous monitoring of the systems and regular updates to the security measures to adapt to new threats and changes in the technology landscape.
Documentation and Accessibility
Clear documentation of these principles is critical. To facilitate easy access and understanding, these are often stored in company wikis or internal knowledge bases. This ensures that everyone from developers to managers can access and apply these guidelines consistently.
