Information security
Sources of standards

The German Federal Office for Information Security (in German Bundesamt für Sicherheit in der Informationstechnik (BSI)) BSI-Standards 100–1 to 100-4 are a set of recommendations including "methods, processes, procedures, approaches and measures relating to information security". The BSI-Standard 100-2 IT-Grundschutz Methodology describes how information security management can be implemented and operated. The standard includes a very specific guide, the IT Baseline Protection Catalogs (also known as IT-Grundschutz Catalogs). Before 2005, the catalogs were formerly known as " IT Baseline Protection Manual". The Catalogs are a collection of documents useful for detecting and combating security-relevant weak points in the IT environment (IT cluster). The collection encompasses as of September 2013 over 4,400 pages with the introduction and catalogs. The IT-Grundschutz approach is aligned with to the ISO/IEC 2700x family.
