LLMResponse AC.L2-3.1.2.a

Based on your document, I'll help you prioritize evidence types for assessing objective [a] under the AC.L2-3.1.2 practice "Transaction & Function Control." This objective aims to determine if "the types of transactions and functions that authorized users are permitted to execute are defined."

For this specific assessment objective, I recommend prioritizing the evidence types in the following order:

1. **Artifacts** - Highest priority

  - Documentation defining user roles and permitted functions (access control matrices)
  - Role descriptions specifying allowed transaction types
  - System configuration settings showing access restrictions
  - Technical implementation of access control lists

2. **Documents** - Second priority

  - Access control policies
  - System security plan sections addressing function control
  - Procedure documentation for transaction authorization
  - User guides explaining permitted actions by role

3. **Screen Share** - Third priority

  - Demonstration of how system access controls are configured
  - View of actual permissions implementations in systems
  - Verification of how permissions are assigned to roles

4. **Physical Review** - Lowest priority

  - Observation of transaction controls in actual operation
  - Review of physical access controls related to function restrictions

Regarding assessment approaches, I recommend the following prioritization:

1. **Examine** - Most important

  - Review access control policy documentation
  - Check system design documents showing how transactions are controlled
  - Look at configuration settings implementing these controls

2. **Interview** - Second priority

  - Speak with system administrators who implement the controls
  - Talk to security personnel who design access restrictions
  - Interview staff who understand how transactions are limited

3. **Test** - Third priority

  - Verify mechanisms are actually working as documented
  - Confirm access control policy implementation

This prioritization puts documentation-based evidence first because defining transaction types is primarily a documentation activity. The examine approach is most important since this objective specifically focuses on whether these transaction types are defined, rather than how well they're implemented.
