1) Discuss the SDLC (System Development Life Cycle)
-SDLC stands for The System Development Life Cycle (SDLC) process applies to information system development projects ensuring that all functional and user requirements and agency strategic goals and objectives are met. The SDLC provides a structured and standardized process for all phases of any system development effort. These phases track the development of a system through several development stages from feasibility analysis, system planning and concept development; to acquisition and requirements definition; design; development; integration and testing; deployment and acceptance; though deployment and production; and finally to system retirement. System Development Life Cycle referred to as the application development life-cycle, is a term used in systems engineering, information systems and software engineering to describe a process for planning, creating, testing, and deploying an information system. The systems development life-cycle concept applies to a range of hardware and software configurations, as a system can be composed of hardware only, software only, or a combination of both.
The SDLC Diagram cycle
The system development life cycle is the overall process of developing, implementing, and retiring information systems through a multistep process from initiation, analysis, design implementation, and maintenance to disposal. There are many different SDLC models and methodologies, but each generally consists of a series of defined steps or phases. For any SDLC model that is used, information security must be integrated into the SDLC to ensure appropriate protection for the information that the system will transmit, process, and store. Applying the risk management process to system development enables organizations to balance requirements for the protection of agency information and assets with the cost of security controls and mitigation strategies throughout the SDLC.
