Class Objectives
/Class Outline Information systems must be designed and operated with careful consideration of the balance among usability, security, and operational cost.
In this course, students will learn the fundamentals of information security and discuss basic cryptographic and authentication technologies that enable secure information exchange in the presence of security threats.
Case studies will be conducted on secure communication and user authentication systems that utilize these technologies.
The course also addresses system design and implementation models for information security that address contemporary security threats, as well as crisis management in information systems, with a particular focus on incident response.
In addition, humans themselves can be regarded as highly complex information systems that may encounter various types of trouble.
Even if technical countermeasures for information systems are well implemented, incidents involving users can still have a significant impact on those systems.
Based on this broad perspective of information systems—including human factors—students will discuss social systems, institutional frameworks, and human factors related to information security.
Through group discussions and presentations, students will examine societal challenges and explore possible responses and countermeasures.
