Practical courses in information security provide students with first-hand knowledge of technical security mechanisms and their weaknesses. However, teaching students only the technical side of information security leads to a generation of students that emphasize digital solutions, but ignore the physical and the social aspects of security. In the last two years we devised a course where students were given a practical assignment which includes a combination of physical security, social engineering and digital penetration testing. As part of the course, the students stole laptops using social engineering from unaware employees throughout the university campus. The assignment provided the students with a practical overview of security and increased their awareness of the strengths and weaknesses of security mechanisms. In this paper we present the design of the practical assignment and the observations from the execution.

The security goals of an organization are realized through security policies, which concern physical security, digital security and security awareness. An insider is aware of these security policies, and might be able to thwart the security goals by combining physical, digital and social means. A systematic analysis of such attacks requires the whole environment where the insider operates to be formally represented. This paper presents Portunes, a framework which integrates all three security domains in a single environment. Portunes consists of a high-level abstraction model focusing on the relations between the three security domains and a lower abstraction level language able to represent the model and describe attacks which span the three security domains. Using the Portunes framework, we are able to represent a whole new family of attacks where the insider is not assumed to use purely digital actions to achieve a malicious goal.@en

Penetration tests on IT systems are sometimes coupled with physical penetration tests and social engineering. In physical penetration tests where social engineering is allowed, the penetration tester directly interacts with the employees. These interactions are usually based on deception and if not done properly can upset the employees, violate their privacy or damage their trust toward the organization and might lead to law suits and loss of productivity. We propose two methodologies for performing a physical penetration test where the goal is to gain an asset using social engineering. These methodologies aim to reduce the impact of the penetration test on the employees. The methodologies have been validated by a set of penetration tests performed over a period of two years.@en

Organizations rely on physical, digital and social mechanisms to protect their IT systems. Of all IT systems, laptops are probably the most troublesome to protect, since they are easy to remove and conceal. When the thief has physical possession of the laptop, it is also difficult to protect the data inside. In this study, we look at the effectiveness of the security mechanisms against laptop theft in two universities. The study considers the physical and social protection of the laptops. We analyze the logs from laptop thefts in both universities and complement the results with penetration tests. The results from the study show that the effectiveness of security mechanisms from the physical domain is limited, and it depends mostly from the social domain. The study serves as a motivation to further investigate the analysis of the alignment of the mechanisms across all three security domains to protect the IT assets in an organization.@en

Organizations rely on physical, technical and procedural mechanisms to protect their IT systems. Of all IT systems, laptops are the probably the most troublesome to protect, since they are easy to remove and conceal. When the thief has physical possession of the laptop, it is difficult to protect the data inside. Organizations open to the public, such as hospitals and universities, are easy targets for laptop thieves, since every day many people wander in the premises. In this study, we look at the effectiveness of the security mechanisms against laptop theft in two universities. We analyze the logs from laptop thefts in both universities and complement the results with penetration tests. The results from the study show that surveillance cameras and access control have a limited role in the security of the organization and that the level of security awareness of the employees plays the greatest role in stopping a theft.@en
