In the current environment, it is wise to incorporate security into your software development lifecycle as early as possible. Historically, security checks were a pre-release gateway for a software team: if you passed, your product/service could go to production. At the same time, security checks used to require a code and environment freeze, while audit preparations led to chaos and a non-systematic approach in collecting important security documentation. All these elements led to a bottleneck for the project team. However, a long wait for security testing results is no longer an option since the typical project pace has significantly increased. Various project models suggest their own approaches for introducing security into software development.
