Secure - System Development Life Cycle The first phase of the systems analysis and design is the preliminary investigation, where the systems analyst performs the systems analysis, design, and implementation. The steps involved in this process, consists of: 1) a preliminary analysis – includes stating the objectives, defining the nature and scope of the problem 2) propose alternative solution – for example leave system along, make it more efficient, or build a new system 3) describe costs and benefits, 4) security requirements 5) submit a preliminary plan with recommendations Assignment: select a problem at work and provide the requested information for each of the steps, in 550- 600 word, discuss the below requirements: 1) Preliminary Analysis a) State the Objectives: (3 to 5 objectives for each of the objectives, along with justification/rationale) b) Define the nature of the Project: (i.e. Project Management, IT Security, Contracting, Procurement) c) Define the Scope: Since system size is a measure of the magnitude of all components of a system that are within the current scope, the system scope should be documented in the project plan before the system size is estimated. The scope statement defines what the project will and will not include, in enough detail to clearly communicate to all participants. The model built in the step defines the scope of the system. The conceptual or scoping model defines the boundaries of the system (i.e., what is in scope and what is out of scope). It identifies: • the events outside the system that cause the system to react • the actors outside the system that interact with the system • the information that flows between the system and the actors outside the system • the major functions included in the system • the user population The conceptual process model includes a: • Statement of Purpose • Context Diagram • Event List • Function Chart • Workgroup Chart 2) Propose alternative solution (3 to 5 alternative solutions, also provide a justification/rationale for each alternative solution) 3) Describe the costs and benefits 4) Describe the security requirements (provide 3 (three) requirements and the justification) 5) Submit a preliminary plan 6) Recommendations (list of 4 – 6 recommendations, with the rationale/justification for each recommendation) Cite three APA sources. In responding to two of your fellow classmates, please provide 3 alternative solutions (along with the solutions, provide a 3 to 5 sentence justification/rationale for your solutions) References Define the System Scope and Boundaries, retrieved from: http://www.testablerequirements.com/testablerequiremen ts/def_sys_scope_bound.htm Defining System Scope.
