The Security - Protection and Reliability division (Fachbereich Sicherheit - Schutz und Zuverlässigkeit) of the German Computer Society (Gesellschaft für Informatik GI) acts as a forum for all specialists active on topics of security, safety, dependability (reliability, availability). Special interest groups (SIGs) support scientific work as well as the exchange of ideas between science and industry. The cross-over characteristic of security topics is reflected in the divisional organization providing the basis for cross-functional work-groups, conferences and other joint activities between the SIGs, but also with other divisions, industrial partners and society in general.

Manfred was founding member of the division, which started in 2001, and was its elected speaker 2001 - 2006.
