Secondary Major in Information Systems or Data Management: Optional Courses

Student Placement

Students can choose it only once during undergraduate studies (either the 7th or the 8th semester).

The purpose of the course is to highlight the necessity of a high-level framework, for the protection of personally identifiable information (PII) within information and communication technology (ICT) systems, general in nature, placing organizational, technical, and procedural aspects in an overall privacy framework. The privacy framework, according to ISO/IEC 29100:2011 and ISO/IEC 29101:2018, is intended to support organizations define their privacy safeguarding requirements related to PII within an ICT environment by defining the actors and their roles in processing PII, describing privacy safeguarding requirements, and referencing known privacy principles. According to ISO/IEC 2913:2017, guidelines are providing for conducting a Privacy Impact Assessment (PIA) as an instrument for assessing the potential impacts on privacy of a process, information system, program, software module, device, which processes PII. Privacy-by-Design critical issues are introduced. Moreover, privacy protection issues in cloud environments are described in detail, according to ISO/IEC 27018:2014.

In this context, the learning outcomes of the course, after its successful completion, are that the students will be able:

to understand the basic concepts of privacy framework as well as how to recognize and analyze privacy requirements
to realize the Privacy-By-Design principle
to conduct a study for Privacy Impact Assessment
to understand and deal with privacy protection issues in cloud environments.
