The requirement, verbatim

NIST SP 800-171 Rev. 2 · 3.3.6

Provide audit record reduction and report generation to support on-demand analysis and reporting.

Requirement 3.3.6, practice name in the CMMC assessment guide: Reduction & Reporting.

NIST's discussion

Audit record reduction is a process that manipulates collected audit information and organizes such information in a summary format that is more meaningful to analysts. Audit record reduction and report generation capabilities do not always emanate from the same system or organizational entities conducting auditing activities. Audit record reduction capability can include, for example, modern data mining techniques with advanced data filters to identify anomalous behavior in audit records. The report generation capability provided by the system can help generate customizable reports. Time ordering of audit records can be a significant issue if the granularity of the time stamp in the record is insufficient.

Assessment objectives

An assessor decides each of these separately. The requirement is met only when every objective is.

  1. [a] an audit record reduction capability that supports on-demand analysis is provided
  2. [b] a report generation capability that supports on-demand analysis is provided
  3. [c] an audit record reduction capability that supports on-demand reporting is provided
  4. [d] a report generation capability that supports on-demand reporting is provided

For assessors: examine, interview, test

NIST SP 800-171A names what an assessor may examine, whom they may interview, and what they may test for this requirement. Assessors select from these lists; they are not a checklist of everything you must produce.

Examine
  • Audit and accountability policy
  • procedures addressing audit record generation
  • procedures for audit review, analysis, and reporting
  • system design documentation
  • system security plan
  • system configuration settings and associated documentation
  • system audit logs and records
  • audit reduction reports
  • audit review and analysis reports
  • other relevant documents or records
Interview
  • Personnel with audit review, analysis, and reporting responsibilities
  • personnel with information security responsibilities
  • system or network administrators
Test
  • Mechanisms implementing audit reduction and report generation capability

Evidence

No evidence examples are published for this requirement yet. The objectives above are what an assessor checks; evidence is whatever shows each one is true in your environment, dated and kept with your system security plan.

Scoring weight

Worth 1 point. Not meeting this requirement subtracts 1 from your 110-point SPRS score.

DoD NIST SP 800-171 Assessment Methodology v1.2.1 weighting, as carried in the Bedrock scoring table. The score starts at 110 and subtracts the weight of every requirement not met.

In Rev. 3

Rev. 2 is what your contract requires today. A standing DoD class deviation keeps Rev. 2 in force; NIST has published Rev. 3, but it is not adopted for contracts. In Rev. 3 this requirement is reworded: 03.03.06 Audit Record Reduction and Report Generation.
