Public security test «SwissCovid Proximity Tracing System»

As part of the Covid-19 proximity tracing project led by the Federal Office of Public Health (FOPH), the National Cyber Security Centre (NCSC) set up a security and privacy task force to assess cybersecurity and privacy issues. The task force is made up of representatives from the Federal Department of Foreign Affairs (FDFA), the Federal Office of Information Technology, Systems and Telecommunication (FOITT), the Federal IT Steering Unit (FITSU) and the National Cybersecurity Centre (NCSC). The task force is also in close contact with the Federal Data Protection and Information Commissioner (FDPIC) and the Federal Office of Justice (FOJ).

The mobile component of the Swiss proximity tracing system consists of an app based on the concept known as DP-3T. This decentralised proximity tracing model makes it impossible for anyone to reconstruct who met whom and when. The representatives of the task force agree that a decentralised approach best meets the Swiss need for maximum protection of privacy. 

The NCSC, led by the federal Cybersecurity Delegate, has been monitoring, advising on and reviewing the ongoing progress of the Swiss proximity tracing system in terms of its security since the task force was set up. As part of a public security test, the security of the entire system is now to be thoroughly tested by other specialists and interested individuals. The public security test will start on 28 May 2020. 

The public security test will be carried out by the National Cyber Security Centre (NCSC) and aims to provide full transparency. Test results are to be reported via the NCSC website, where there is a form for entering detailed information. The NCSC will receive these reports, evaluate their contents, prioritise them according to their criticality and, if necessary, arranges remedies. Existing feedback is publicly available on the NCSC website and is updated regularly.
