Running h ead : CASE STUDY 3: SECURITY 1 Case Study 3: Security Marilyn Washington CIS 524 - Computer Interaction and Design Professor Moses Cowan May 22, 2015 In this paper, various design issues related to a restaurant's touch screen register system are discussed, with recommendations for improvement in areas such as system security, usability, and overall functionality. Based on the analysis provided, critically assess the design issues, including security flaws, usability concerns, and system performanc e problems. Propose a comprehensive solution to address these issues, detailing the tasks associated with improving the system. In your response, discuss how the system's security and usability can be balanced to enhance user experience while maintaining d ata protection. Additionally, suggest any security enhancements that could be implemented to improve the system's overall safety without sacrificing ease of use. Word Count Requirement: 1,000 - 1,200 words.

The design process is presented based on six phases: the initial , design , Implementation, Monitor Control Phase , Test Phase, and close phase, and the detailed design phase. Each is design to perform a major task SECURITY 3 within the project at pre - defined time. The phases are the guide of the project from start to finish. It provides a way for the project team and management to track the progress of the project. It also provides a detailed list on what is scheduled during each phase. Security Analyze the new system and determine the design issues with this new system. With the initial phase of the system design there is not a process in place for allowing multiple logons at the same time without restarting the system. The systems design is configured
