Data processing systems must fulfil various requirements and conditions to ensure that a minimum level of security is ascertained in information technology. Traditionally, these standard requirements include:
In addition to the standard basic values of IT security, further aspects have to be taken into consideration. The Berlin Data Protection Act (Berliner Datenschutzgesetz; "BlnDSG "), for instance, requires that the following be assured in addition to the aforementioned basic values:
Authenticity: Authenticity means that data are traceable to their origin at any time.
Auditability: Auditability refers to process control. It is deemed ensured if it can be verified how and when which data entered the IT system.
Transparency: Transparency is deemed ensured if the IT process is comprehensible to the respective specialists within a reasonable period of time and taking reasonable efforts. In general, this requires an up-to-date and adequate documentation.
