Ethical Hacking of an IoT-device: Threat Assessment and Penetration Testing : A Survey on Security of a Smart Refrigerator
Internet of things (IoT) devices are becoming more prevalent. Due to a rapidly growing market of these appliances, improper security measures lead to an expanding range of attacks. There is a devoir of testing and securing these devices to contribute to a more sustainable society. This thesis has evaluated the security of an IoT-refrigerator by using ethical hacking, where a threat model was produced to identify vulnerabilities. Penetration tests were performed based on the threat model. The results from the penetration tests did not find any exploitable vulnerabilities. The conclusion from evaluating the security of this Samsung refrigerator can say the product is secure and contributes to a connected, secure, and sustainable society.Internet of Things (IoT) enheter blir mer allmÀnt förekommande.

Sodium content in Swedish processed food items compared to other countries
Funding Acknowledgements
Type of funding sources: None.
Background
Dietary sodium has a dose-response relationship with cardiovascular disease, and sodium intake in Sweden exceeds national and international recommendations. Two thirds of dietary sodium intake comes from processed foods, and adults in Sweden eat more processed foods than any other European country. We hypothesised that sodium content in Swedish processed foods is higher than other countries due to the high sodium intake in the Swedish population.
Purpose
To investigate sodium content in Swedish processed food items, and how it differs from Australia, France, Hong Kong, South Africa, the United Kingdom and the United States.
Method
Data were collected from retailers by trained research staff using standardised methods. Ten food categories were compared using Kruskal-Wallis test of ranks.
Results
Compared to other countries, Sweden had among the highest sodium content in the âdairyâ and âconvenience foodsâ categories, but among the lowest in âcereal and grain productsâ, âseafood and seafood productsâ and âsnack foodsâ categories. The highest sodium contents in the Swedish data were found in the âmeat and meat productsâ category.
Conclusion
Contrary to our hypothesis, Swedish processed foods had overall lower sodium content than most other included countries. Sodium content differed substantially between countries in all food categories. Swedish foods had higher sodium content than other countries in increasingly consumed food categories
