Security considerations for the spiral development model

Security measures have been well established within the waterfall development life cycle model. However, more software projects are using the spiral development life cycle model. Software developers and project managers can easily forget about adapting security measures within this new approach (Daud, 2010). The spiral model uses iterative steps that can create changes in each phase of software development process. This will challenge security to ensure the application has few flaws or vulnerabilities that could be exploited. Failure to impose the right security measures at each of these phases can open up vulnerabilities for hackers to exploit and prove costly in patching. This paper will explore areas where security can be engaged within each iteration step of the spiral development model. This way security can continue protection of the software product as it becomes ready for deployment. The paper is broken down into sections describing the spiral development model and what security methods are needed at each step. The first section describes an overview of spiral development model to set the framework of where security will be suggested. The next section describes security methods recommended at different parts of spiral development model. The paper will help organizations realize where to deploy security measures to reduce vulnerabilities in the software application.
