3.2.4 Determine the Combined Impact Level for Each User Group

The impact assessment levels for each user group are combined to establish a single impact level to represent the risks to impacted entities from a compromise of identity proofing, authentication, and/or federation functions for that user group.

Organizations can apply a variety of methods for this combinatorial analysis, such as:

Using a high-water mark approach across the various impact categories and impacted entities to derive the effective impact level

Assigning different weights to different impact categories and/or impacted entities and taking an average to derive the effective impact level

Some other combinatorial logic that aligns with the organization’s mission and priorities

Organizations SHALL document the approach they use to combine their impact assessment into an overall impact level for each of their defined user groups and SHALL apply it consistently across all of its online services. At the conclusion of the combinatorial analysis, organizations SHALL document the impact for each user group.

The outcome of this step is an effective impact level for each user group due to a compromise of the identity management system functions (i.e., identity proofing, authentication, federation).
