The Federal Ministry of Finance (BMF) and the Deutsche Bundesbank (BBk) have decided to implement the European System of Central Banks' (ESCB's) Threat-Intelligence Based Ethical Red Teaming (TIBER) framework for ethical penetration testing as “TIBER-DE" for Germany. The framework for TIBER-DE was developed jointly with the Federal Financial Supervisory Authority (Bundesanstalt für Finanzdienstleistungsaufsicht - BaFin) and the Federal Office for Information Security (BSI). With TIBER-DE, banks, insurance companies, financial market infrastructures and their most important service providers can put their own cyber defence to the test. Under the coordination of the BBk, ethical hackers are commissioned to overcome the client's security mechanisms and penetrate his information systems. The companies can then close the weak points and take preventive measures against actual hacker attacks. Participation in TIBER tests is not mandatory for German institutions; however, it is strongly recommended that they carry out a TIBER test to expand and improve their cyber defence systems.
