MON-08.4: Dual Authorization for Event Log Movement
Automated mechanisms exist to enforce dual authorization for the movement or deletion of event logs.
Control Question: Does the organization use automated mechanisms to enforce dual authorization for the movement or deletion of event logs?
General (3)
| Framework | Mapping Values |
|---|---|
| NIST 800-53 R4 | AU-9(5) |
| NIST 800-53 R5 (source) | AU-9(5) |
| NIST 800-53 R5 (NOC) (source) | AU-9(5) |
Capability Maturity Model
Level 0 — Not Performed
There is no evidence of a capability to enforce dual authorization for the movement or deletion of event logs.
Level 1 — Performed Informally
C|P-CMM1 is N/A, since a structured process is required to enforce dual authorization for the movement or deletion of event logs.
Level 2 — Planned & Tracked
C|P-CMM2 is N/A, since a well-defined process is required to enforce dual authorization for the movement or deletion of event logs.
Level 3 — Well Defined
Continuous Monitoring (MON) efforts are standardized across the organization and centrally managed, where technically feasible, to ensure consistency. CMM Level 3 control maturity would reasonably expect all, or at least most, the following criteria to exist: o Governs asset management that ensures compliance with requirements for asset management. o Leverages a Configuration Management Database (CMDB), or similar tool, as the authoritative source of IT assets. o Centrally collects logs and is protected according to the manufacturer’s security guidelines to protect the integrity of the event logs with cryptographic mechanisms. o Monitors the organization for Indicators of Compromise (IoC) and provides 24x7x365 near real-time alerting capability. o Is configured to alert incident response personnel of detected suspicious events such that incident responders can look to terminate suspicious events.
- An IT Asset Management (ITAM) function, or similar function:
- A Security Incident Event Manager (SIEM), or similar automated tool:
- Both inbound and outbound network traffic is monitored for unauthorized activities to identify prohibited activities and assist incident handlers with identifying potentially compromised systems.
Level 4 — Quantitatively Controlled
Continuous Monitoring (MON) efforts are metrics driven and provide sufficient management insight (based on a quantitative understanding of process capabilities) to predict optimal performance, ensure continued operations and identify areas for improvement. In addition to CMM Level 3 criteria, CMM Level 4 control maturity would reasonably expect all, or at least most, the following criteria to exist:
- Metrics reporting includes quantitative analysis of Key Performance Indicators (KPIs).
- Metrics reporting includes quantitative analysis of Key Risk Indicators (KRIs).
- Scope of metrics, KPIs and KRIs covers organization-wide cybersecurity and data protection controls, including functions performed by third-parties.
- Organizational leadership maintains a formal process to objectively review and respond to metrics, KPIs and KRIs (e.g., monthly or quarterly review).
- Based on metrics analysis, process improvement recommendations are submitted for review and are handled in accordance with change control processes.
- Both business and technical stakeholders are involved in reviewing and approving proposed changes.
Level 5 — Continuously Improving
See C|P-CMM4. There are no defined C|P-CMM5 criteria, since it is reasonable to assume a continuously-improving process is not necessary to enforce dual authorization for the movement or deletion of event logs.
Assessment Objectives
- MON-08.4_A01 critical or sensitive system and organizational operations for which dual authorization is to be enforced are identified.
- MON-08.4_A02 dual authorization is employed to execute critical or sensitive system and organizational operations.
