Assessment Objectives

In addition to relevant policies, standards and procedures, the assessor shall examine, interview, and/or test to determine if appropriately scoped evidence exists to support the claim that:

• MON-05_A01 the frequency at which system audit records are reviewed and analyzed is defined.
  Defined parameters: at least weekly
  Assessment rigor: 1
  Origin: 171A_R3_A.03.03.05.ODP[01]
• MON-05_A02 system audit records are reviewed and analyzed per an organization-defined frequency for indications and the potential impact of inappropriate or unusual activity.
  Defined parameters: at least weekly
  Assessment rigor: 1
  Origin: SCF Created
• MON-05_A03 audit records across different repositories are analyzed to gain organization-wide situational awareness.
  Assessment rigor: 1
  Origin: 171A_R3_A.03.03.05.c[01]
• MON-05_A04 automated mechanisms used for integrating audit record review, analysis and reporting processes are defined.
  Assessment rigor: 1
  Origin: 53A_R5_AU-06(01)_ODP
• MON-05_A05 audit record review, analysis and reporting processes are integrated using organization-defined automated mechanisms.
  Assessment rigor: 1
  Origin: 53A_R5_AU-06(01)
• MON-05_A06 the frequency or situation requiring logging for each specified event type is defined.
  Defined parameters: continually for each identified event type
  Assessment rigor: 3
  Origin: 53A_R5_AU-06_ODP[01] 53A_R5_AU-02_ODP[03]
• MON-05_A07 the event logging function is coordinated with other organizational entities requiring audit-related information to guide and inform the selection criteria for events to be logged.
  Assessment rigor: 3
  Origin: 53A_R5_AU-02b.
• MON-05_A08 the event types selected for logging are reviewed / updated organization-defined frequency.
  Defined parameters: annually and whenever there is a change in the threat environment
  Assessment rigor: 2
  Origin: 53A_R5_AU-02e.
• MON-05_A09 a rationale is provided for why the event types selected for logging are deemed to be adequate to support after-the-fact investigations of incidents.
  Assessment rigor: 3
  Origin: 53A_R5_AU-02d.
• MON-05_A10 system audit records are reviewed and analyzed per an organization-defined frequency for indications of organization-defined inappropriate or unusual activity and the potential impact of the inappropriate or unusual activity.
  Defined parameters: at least weekly
  Assessment rigor: 3
  Origin: 53A_R5_AU-06a.
• MON-05_A11 findings are reported to organization-defined personnel or roles.
  Assessment rigor: 3
  Origin: 53A_R5_AU-06b.
• MON-05_A12 the level of audit record review, analysis and reporting within the system is adjusted when there is a change in risk based on law enforcement information, intelligence information or other credible sources of information.
  Assessment rigor: 3
  Origin: 53A_R5_AU-06c.
• MON-05_A13 system audit records are reviewed and analyzed <A.03.03.05.ODP[01]: frequency> for indications and the potential impact of inappropriate or unusual activity.
  Defined parameters: at least weekly
  Assessment rigor: NIST 800-171
  Origin: 171A_R3_A.03.03.05.a
• MON-05_A14 a Security Incident Event Manager (SIEM), or similar automated tool, centrally collects event logs and security-relevant telemetry.
  Assessment rigor: 1
  Origin: SCF Created
