Abstract:State-of-the-art literature suggests that traditional perimeter security is not applicable to the current network infrastructure. Reasons include the migration of data to cloud service providers and employees increasingly working from home, making it difficult to place a perimeter. The goal of this thesis is to get a practical understanding of lesser-known attack surfaces and to measure the compliancy level of employees on the current perimeter security guidelines at the Port of Rotterdam, scoped down to the IT department. This was done in the form of a questionnaire and interviews. Results from the questionnaire show that a significant number of employees avoid using the company laptop or using a VPN when at work, both of which are common policies. The main reasons for doing so are to improve their ability to work, not knowing these policies, and forgetting such policies. The interviews show that there is a need for improved communication and a wish for active involvement of security officers within their teams. Additionally, not all data from every team interviewed goes through the broker network. In conclusion, this study took a critical look at the current security policies and proposes among other best practices the adaptation of a zero-trust network.
