phaidra.ustp.at o:7858 Information Security Management in Heterogeneous SystemsIdentifying the challenges This paper discusses security from the perspective of heterogeneity, which so far has not been in the focus of security research. After carrying out the state of the art analysis conforming this position, this phenomenon is further discussed. However, one of the major conclusions derived by the authors is that a secure heterogeneous environment is an achievable goal. Existing services suffer from the problem of not having a common definition on how to communicate with and trust each other, as well as how to choose the right service for a specific requirement or action. To address this gap, the paper will focus on specifying the requirements for common, standardised interfaces for specific layers. These requirements are intended to be used for supporting the development of a more secure, diverse system landscape. The paper then continues with discussing potential use cases for the requirements and then presents still open challenges that need a scientific solution. The major conclusions drawn from the state of the art analysis are again summarized in the final chapter of this paper. eng heterogeneity interfaces data exchange federation standardisation Computersicherheit Cybersecurity Cyber Security Datenverarbeitungssystem / Sicherheit Computer / Sicherheit Cybersicherheit 2026-09-15T06:52:25.080Z LOMv1.0 Author BEGIN:VCARD VERSION:3.0 N:Lackner;Paul; FN:Paul Lackner END:VCARD https://w3id.org/kim/hcrt/scheme https://w3id.org/kim/hcrt/text Textdokument Text LOMv1.0 yes https://creativecommons.org/licenses/by-sa/4.0 application/pdf 642036 https://phaidra.ustp.at/o:7858 https://phaidra.ustp.at/api/object/o:7858/thumbnail LOMv1.0 discipline https://w3id.org/oerbase/vocabs/oefos2012 https://w3id.org/oerbase/vocabs/oefos2012/1 NATURAL SCIENCES NATURWISSENSCHAFTEN https://w3id.org/oerbase/vocabs/oefos2012/102 Computer Sciences Informatik https://w3id.org/oerbase/vocabs/oefos2012/1020 Computer Sciences Informatik https://w3id.org/oerbase/vocabs/oefos2012/102015 Information systems Informationssysteme https://w3id.org/oerbase/vocabs/oefos2012 https://w3id.org/oerbase/vocabs/oefos2012/1 NATURAL SCIENCES NATURWISSENSCHAFTEN https://w3id.org/oerbase/vocabs/oefos2012/102 Computer Sciences Informatik https://w3id.org/oerbase/vocabs/oefos2012/1020 Computer Sciences Informatik https://w3id.org/oerbase/vocabs/oefos2012/102016 IT security IT-Sicherheit https://w3id.org/oerbase/vocabs/oefos2012 https://w3id.org/oerbase/vocabs/oefos2012/1 NATURAL SCIENCES NATURWISSENSCHAFTEN https://w3id.org/oerbase/vocabs/oefos2012/102 Computer Sciences Informatik https://w3id.org/oerbase/vocabs/oefos2012/1020 Computer Sciences Informatik https://w3id.org/oerbase/vocabs/oefos2012/102034 Cyber-physical systems Cyber-Physical Systems
