IT security management system (ISMS)

Deutsche Leasing operates an IT security management system in accordance with the ‘secure IT operations’ framework (SITB) from the SIZ GmbH in Bonn. This framework is based on the internationally acknowledged standard ISO 27001 from the International Organization for Standardization (ISO) in Geneva and the German ‘IT baseline protection’ standard set by the Federal Office for Information Security (BSI) in Bonn. Other regulatory requirements and industry standards have been incorporated into the SITB framework, such as the german “Supervisory Requirements for IT in Financial Institutions” (Bankaufsichtliche Anforderungen an die IT – BAIT). This ensures, that technical and organizational security measures to specific aspects of information security are in line with the latest state of technology.
