Course Description

Built on the foundation of the Information Security and Trust course (IS302), this course draws on hard-won experience to explain the latest developments in security protocols, network security, web security, application security and industrial standards. Classroom instruction and discussion will closely integrate technical principles with real world applications such as secure e-banking, secure corporate networking, secure messaging in healthcare environment and multimedia system security. In addition, case studies will be used to demonstrate that security and trust are not only for protection of information assets, but also means of improving business operation or even starting new businesses. Besides the textbook knowledge, this course also brings to the classroom security practices in industries, e.g. Microsoft, and government agencies (e.g IRAS and CSIT).
