What is Control Systems

The importance of personal data and managing them is increasing worldwide. However first, one must be able to distinguish between data, information, and knowledge, before one turns to protecting them. Furthermore, it must be considered that, in open systems, security is a relative term and can be characterized only with the term risk. This suggests that security is not a state in open and dynamic systems but can only be maintained on a pre-defined level (conservation status) with a security management system. Data privacy therefore requires security management systems to ensure sustainable protection at a previously defined level. Pure guidelines and policies are just not sufficient for the protection of data in open systems, as is typical in companies.
