Application containers and a microservices architecture are being used to design, develop, and deploy applications leveraging agile software development approaches such as Development Operations. Security needs to be embedded into these software development approaches. This presentation based on CSA research artifact 'Best Practices in Implementing Secure Microservices Architecture' will help to identify best practices in securing microservices in the engineering of trustworthy secure systems through the lens of the Developer, Operator, and Architect.
