Tehtävien eriyttäminen

Organisation should have processes for ensuring that conflicting responsibilities are segregated to reduce opportunities for misuse of the organization’s assets.

Care should be taken e.g. in relation to a single person being able to process data without detection. Often also separating the initiation of an event from its authorization is a good practice.

When direct segregation of duties is hard to achieve, the following principles can be utilized:

• High-level segregation of information security responsibilities
• Supporting segregation with good monitoring, audit trails and management supervision
