Abstract
This paper demonstrates how a local attack against a city traffic controller located in a public area can be detected and mitigated in a cost-effective way. This is done by applying a general security methodology, an architecture and a set of new and existing tools integrated by the PRECYSE EU-project. The traffic controller does not contain built-in security and is connected to an information panel which is used for displaying traffic messages. The proposed solution is integrated with the incident management system of the city traffic control centre. This allows for increasing the situation awareness about attacks, as well as supporting a workflow for restoring the attacked device to its normal state and ensuring attack investigation.
