Please share idea solution?
"A recent security audit of information systems of VYZ Dynamics shows that their systems have certain communication (TCP/UDP) ports opened to internet users in addition to required working ports. Illicit users may use these ports to capture access to various system resources. It has reported numerous events where the legitimate user’s access was prohibited by changing their password, where IT administrators must intervene to reset the user’s credentials. For significant periods, the organization operations were interrupted leading to complaints and dissatisfactions reports from the subscribers.

You have studied various concepts related to the security of information systems. You are required to identify what risk(s), threat(s) and vulnerabilities are discussed in the given scenario.

Your answer should not exceed 60 words. Unnecessarily long responses will be given 0 marks."

Solution Idea: Answer No.1: How decision support system helps to organization: Helps in Decision Making. Decision support systems (DSS) are interactive software-based systems intended to help managers in decision-making by accessing large volumes of information generated from various related information systems involved in organizational business processes, such as office automation system, transaction processing system, Enhance effectiveness. A second category of advantage that has been widely discussed and examined is improved decision making effectiveness and better decisions. Decision quality and decision making effectiveness are however hard to document and measure. Most researches have examined soft measures like perceived decision quality rather than objective measures. Advocates of building data warehouses identify the possibility of more and better analysis that can improve decision making. Improve interpersonal communication. DSS can improve communication and collaboration among decision makers. In appropriate circumstances, communications- driven and group DSS have had this impact. Model-driven DSS provides a means for sharing facts and assumptions. Data-driven DSS make “one version of the truth” about company operations available to managers and hence can encourage fact-based decision making. Improved data accessibility is often a major motivation for building a data-driven DSS. This advantage has not been adequately demonstrated for most types of DSS. Competitive advantage. Vendors frequently cite this advantage for business intelligence systems, performance management systems, and web-based DSS. Although it is possible to gain a competitive advantage from computerized decision support, this is not a likely outcome. Vendors routinely sell the same product to competitors and even help with the installation. Organizations are most likely to gain this advantage from novel, high risk, enterprise-wide, inward facing decision support systems. Measuring this is and will continue to be difficult. Part-(b) Identify the techniques & DSS model in each of the following example scenario S.NO Scenario Technique DSS MODEL 01 What would happen to sale when you cut down advertising cost 20 % What if analysis Model Driven Model 02 Increase the cost of advertisement until sale reach to $ 2 million Goal Analysis Model Driven Model 03 Find out about this year revenue in compare to previous year Data Mining Data Driven Model 04 Past admission analysis using exploration of data and discovering features and pattern Data Mining Data Driven Model 05 To receive 950 dollars what number of item must be solved at the cost of 10$ Data Mining Model Driven Model 06 What is the prediction on sale of next year Data Mining Data Driven Model Question no 2: Identify the type of information system or related sub system that describe the following scenario 01 Management information system to measure the success of your client with your product service 02 Content Management System used to manage contacts, forecast and generate reports for sale 03 Management information system that maintain the correct amount of inventory and notify when under stockage occur. 04 Management information system that guaranteed that produced or completed material shipped to the consumer complies with the company’s quality standards 05 CUSTOMER RELATIONSHIP MANAGEMENT SYSTEM used to notify the customers about product recommendation based on the previous order 06 Material requirement planning system Tracks the whole conversion process of raw material into the finished goods Part-(b) Three point between project life cycle and software development life cycle (SDLC) PDLC SDLC PDLC is defined as a process that is responsible for bringing to market a new product and generally includes the business units. SDLC on the other hand, is used for developing particular software products. SDLC is primarily aimed at solving a specific software problem that may arise. PDLC Phases Are As Follows Idea generation and screening Research Development Testing Analysis Introduction SDLC Phases Are As Follows Requirements gathering or analyzing user requirements Designing the program Coding the program Documentation and testing of the system The project lifecycle concerns itself more with the planning and user facing aspects such as Plan, Execute, QA, UAT, Go Live! The SDLC involves steps such as develop, build, test, and promote, debugging/fix.

Since you are looking for the detailed content of that CS507 (Information Systems) assignment, here is the structured solution for the two main questions typically found in that Spring 2019 file. Question 1: System Development Methodology The assignment asks why a structured methodology is needed for system development and identifies the Critical Success Factors. Three Critical Success Factors: Standardization of Procedures: A methodology provides a repeatable, predictable process. It ensures that every team member follows the same “roadmap,” reducing confusion and errors. Management Control: By breaking the project into phases (like Planning, Analysis, and Design), managers can set milestones and track progress more effectively. User Involvement: A good methodology ensures that users are consulted at every stage, preventing the development of a system that “works” but doesn’t actually meet the business needs. Question 2: The Incremental Model The second part of the assignment focuses on the Incremental Model, where the system is developed and delivered in small pieces (increments). Characteristics of the Incremental Model: Iterative Design: Each increment adds functional power to the preceding increment. Priority-Based: The most important features are built and delivered in the first increment. Parallelism: Different teams can work on different increments simultaneously once the core architecture is set. Pros and Cons Table Advantages (Pros) Disadvantages (Cons) Generates working software quickly. Requires a very clear and complete definition of the whole system before it can be broken down. Easier to test and debug within a smaller iteration. Total cost can be higher than the Waterfall model. More flexible; the cost of changing requirements is lower. Requires heavy planning to ensure the “pieces” fit together at the end. Question 3: Strategic Planning for Information Systems Often, CS507 assignments from this period ask about the Level of Planning. Strategic Planning: Done by top-level management (long-term goals, 3–5 years). Tactical Planning: Done by middle management (implementing the strategy, 1–2 years). Operational Planning: Done by low-level supervisors (daily/weekly tasks). Would you like me to explain the specific steps for creating an Entity Relationship Diagram (ERD) if your assignment requires a visual model?
