About Multi-Metrics
The Multi-Metrics Approach has the goal to to measure the Security, Privacy and Dependability (SPD) level of a system. The objective is to achieve an overall system SPD level, SPDSystem. The main advantage of this methodology is that it provides a simple mechanism to measure and evaluate the system security, privacy and dependability levels.
SPDSystem is a triplet, composed of individual Security, Privacy and Dependability levels (s,p,d). Each of the levels is represented by a range between 0 and 100, i.e. the higher the number, the higher the Security, Privacy and Dependability level. However, in order to end up with SPDSystem, during the whole process, the criticality is evaluated. Criticality is again a triplet (Cs,Cp,Cd), defined as the complement of SPD, and expressed as (Cs, Cp, Cd) = (100, 100, 100) − (s, p, d).
The Figure shows a system being composed of multiple sub-systems, which at the same time consist of various components.
Challenges
Identified challenges are related to
- industrial harmonisation of methodology
- semantic description of security, privacy and dependability
- identification of s,p,d values for use cases, e.g. monitoring, alarm, control
Expected outcome
Year 1:
- System analysis for main sub-systems on current infrastructure (M12)
- identification of 3-5 use cases, to be further elaborated in T3.1 (M12)
- Feedback from industry on applicability of system analysis (M12)
Year 2:
- Extension of the Smart Grid system to include at least 2 new functionalities (M24)
- Identification of challenges for industrial applicability (M24)
Y3:
- to be defined in year 2
