Adopting a DevSecOps approach has implications for every stage of the product lifecycle:
From the design of a new product, the teams are aware of their responsibilities in terms of safety and reliability and trained to manage them. For large efforts, teams begin by quickly modeling threats and risks, then identify and prioritize the backlog items needed to make the product secure, reliable, and compliant. Whenever possible, teams leverage existing architectural designs that have been developed in conjunction with security and reliability experts, ensuring best practices are followed and accelerating planning and design.
To improve code quality, developers continually develop and update their knowledge of secure and resilient coding practices. They take full advantage of reusable coding patterns, components, and microservices to rapidly build the functionality and services needed to meet common security and resiliency requirements for encryption, authentication, availability, and observability.
Instead of having a group of specialists review a product for security vulnerabilities and resiliency issues once it emerges from months of development, teams review code as often as every two weeks in part of regular agile sprints, using both automated and manual checks. After automated code analysis tools like SonarQube and Fortify scan for vulnerabilities and known issues, senior developers conduct peer reviews to discuss the results and ensure the software meets appropriate standards.
Engineers create automated security tests to run alongside automated functional and performance tests. This not only ensures that testing is consistent and efficient, but also makes security requirements explicit, so developers don’t waste time figuring out how to satisfy ill-defined policies established by separate groups. Common security tests, such as penetration tests that look for security vulnerabilities in systems, are performed automatically as part of each sprint and release cycle.
Code is delivered to production hosting environments, not through manual processes detailed in checklists, but through well-designed automated processes that ensure the right software is built and deployed in a safe and secure manner. reliable. Additionally, best-practice companies have secure production hosting environments that can be quickly invoked through application programming interfaces (APIs), eliminating wait times and reducing risk.
Once the software is in production, automated processes including real-time monitoring, host and network intrusion detection, compliance validation, and evidence attestation are used to increase efficiency and detect vulnerabilities. If defects or vulnerabilities are discovered, resolutions are identified, prioritized, and tracked to ensure product reliability and security are continually improved.
