Tasks undertaken by the federal government should be handled efficiently, in a citizen-friendly manner and to high quality standards. Digitised, state-of-the-art administration can be a crucial factor in achieving this. For digitisation to be successful over time and find the necessary acceptance among citizens, it must be designed securely from the very beginning. The BSI plays a vital role in this respect. As the federal government's cyber security authority, the BSI creates the basis for ensuring that sensitive data is adequately protected and that practical digital applications can be provided securely. In this way, the BSI contributes to the design of a modern, trustworthy administration.
