SDLCSystems development life cycle (SDLC) is process of developing information systems through analysis, design, investigation, implementation and maintenance. SDLC is called as information systems development or application development. (SDLC) is methodology and design for implementation of information security within the organization.Methodology is formal approach to problem solving based on the structured sequence of procedures. By using a methodology ensures a rigorous process avoids omitting the steps. Goal is creating a comprehensive security program. Traditional SDLC consists of six general phases that is shown in the Figure given below.
