Study Notes
- DevSecOps is a methodology that integrates security into software development, IT operations, and Agile methodologies.
- DevSecOps aims to automate the integration of security throughout the software development lifecycle.
- Agile software development focuses on developing solutions quickly and efficiently with a customer-oriented approach.
- The DevOps movement began as a response to the need for collaboration between development and operations teams to rapidly deliver software.
- DevSecOps addresses security concerns as they arise in the development process, making it more cost-effective and efficient than traditional security methods.
- DevSecOps involves collaboration between development, security, and IT operations teams to create a shared responsibility for software and infrastructure security.
- Agile software development principles include iterative development and a focus on customer satisfaction.
- The software development lifecycle (SDLC) is a sequence of actions followed by various development methodologies, from planning and requirements engineering to design, implementation, and testing.
- In Agile methodologies, requirements are gathered through collaboration with business stakeholders and documented in a backlog of activities.
- Software architecture and design follow well-established patterns, with the use of architecture frameworks and design patterns.
- Development teams should provide working software as rapidly as possible, with regular engagement with business stakeholders to ensure expectations are met.
- Testing is a crucial part of the SDLC, with a range of tests performed to ensure code integrity, functional correctness, performance, and security.
- The V-model methodology is a testing approach that includes verification and validation phases.
