SYSTEMS DEVELOPMENT LIFE CYCLE DEFINITION

Systems development life cycle: a definition

The term “systems development life cycle” is used frequently in conversations about the development of software and other technology projects. But many who use the term have only a rough understanding of what it means – and of the importance of securing it.

So what is system development life cycle? Here’s a brief introduction that provides a systems development life cycle definition and some information on the best way to introduce security into all systems development life cycle phases.

A systems development life cycle definition

The systems development life cycle is a phrase used in systems engineering, information systems and software engineering that outlines a process for successfully bringing a project from start to finish.

What are the stages of the systems development life cycle, by definition?

The systems development life cycle definition commonly includes seven stages: planning, systems analysis & requirements, systems design, development, integration & testing, implementation, and operations & maintenance.

These stages outline a multistep, iterative process that can help to deliver a quality system which meets or exceeds a client’s requirements and expectations.

What are systems development life cycle models?

Some of the most common models for system development life cycle are the waterfall, spiral, V -shaped and agile models. For many developers, the agile systems development life cycle, by definition, is the model that allows the most rapid delivery of high-quality products

A secure systems development life cycle: a definition

When the goal of a systems development life cycle is to produce quality software, security is a top concern. Software applications are the most attacked part of the security perimeter today, and most successful breaches begin by exploiting a flaw or weakness within an application. To produce secure software, the systems development life cycle must include a variety of software testing techniques to find and fix flaws before they can be exploited by attackers.

Security testing for the systems development life cycle.

For development teams that want to improve application security without introducing delay into the systems development life cycle, CA Veracode provides a suite of cloud-based testing technologies that can integrate with any SDLC model. Available as a subscription service, CA Veracode’s testing techniques include static and dynamic analysis as well as tools for mitigating risk in open source and third-party applications. With CA Veracode, developers can test software from inception through production to find and fix flaws at the most cost-efficient point in the development process.
