In order to make use of this trade-off, tunable security services providing several security configurations that can be selected at run-time are needed. LÄS MER
3. Visualising Security through Computer Games : Investigating Game-Based Instruction in ICT Security:an Experimental Approach
Sammanfattning : This thesis investigates whether learning materials in the form of computer games can increase knowledge and comprehension in the area of ICT security.Through a series of experiments carried out in Sweden between the years 2000 and 2003, investigating theoretical knowledge as well as practical knowledge gained through a single-user computer game, data were collected and subjected to quantitative and qualitative analyses. LÄS MER
Sammanfattning : This thesis presents research on computer security vulnerabilities in general-purpose operating systems. The objective is to investigate intrusions in such systems in order to find and model the underlying generic weaknesses, i.e., weaknesses that would be applicable to many different systems. LÄS MER
