Understanding Secure Application Development, Deployment, and Automation

There are two main models of the Software Development Life Cycle (SDLC), the first being an older version that is called Waterfall, where each stage is completed before the next stage commences. This is known as a cascade model. The newer, faster, and more flexible model is called Agile, which is similar to Scrum, where several stages of development can occur simultaneously. Agile is customer-focused, and each part of the project is called a sprint that has many tasks assigned to it. If you have three stages, then there are three sprints. Say each sprint has three tasks. The project concludes when all tasks within each sprint are complete, making that sprint complete. The whole project is complete when all of the sprints are complete.

Before applications can be used in a production environment, we must ensure that they are as secure as possible so that we mitigate the risk of being attacked by an outside agency...
