Policy analysis

As explained in Authorization in Action

Policy analysis is the systematic examination of authorization policies to determine whether they satisfy specified logical or security properties.

Policy analysis systematically examines authorization rules to determine whether they express organizational intent and produce the expected security outcomes. It is especially valuable when small policy changes interact in ways that are difficult to predict. section 17.2 section 17.3

Effective analysis connects policy design with observed authorization behavior:

  • Draft, clarify, and refine candidate policies while keeping the policy engine as the enforcement authority. section 17.2
  • Ground questions in concrete requests, expected results, entities, actions, attributes, and the actual schema. section 17.2.3
  • Compare intended rules with production decisions to expose mismatches, surprising outcomes, edge cases, and governance concerns. section 17.3

Concrete request analysis

Ask, “What would change if this request were made outside business hours?” or “Which policy denies access when the requester is not a workspace member?” Checking the answer against the actual model makes unsupported entities, actions, or attributes visible. section 17.2.3

Figure 17.3 Design-time intent versus runtime reality. Authorization policies are created to express intent at design time, while their effects are revealed through observed decisions at runtime. Comparing these two perspectives (how policies were intended to work and how they actually behave in production) helps teams identify mismatches, unexpected outcomes, and areas that need governance review.

Compare policy intent at design time with authorization decisions observed at runtime to identify mismatches and guide governance review. section 17.3

How Authorization in Action covers it

How deep it goes
Explains concrete-request analysis, schema checking, and runtime comparison, but does not provide detailed enforcement algorithms.
Examples
Uses outside-business-hours requests, workspace-membership denials, schemas, and production decision logs as analysis artifacts.
What it assumes
Assumes an authorization model with defined policies, entities, actions, attributes, relationships, and contextual request data.
What you can do after
Evaluate policy behavior, explain authorization outcomes, identify edge cases, and detect gaps between intended and observed decisions.
How it connects
Connects authorization policies with policy engines, schemas, runtime decisions, decision logs, organizational intent, and governance.
