MON-18: File Activity Monitoring (FAM)
Automated mechanisms exist to monitor sensitive/regulated data in Technology Assets, Applications and/or Services (TAAS) and data repositories.
Control Question: Does the organization use automated tools to monitor sensitive/regulated data in Technology Assets, Applications and/or Services (TAAS) and data repositories?

Capability Maturity Model
Level 0 — Not Performed
There is no evidence of a capability to monitor sensitive/regulated data in Technology Assets, Applications and/or Services (TAAS) and data repositories.
Level 1 — Performed Informally
C|P-CMM1 is N/A, since a structured process is required to monitor sensitive/regulated data in Technology Assets, Applications and/or Services (TAAS) and data repositories.
Level 2 — Planned & Tracked
Continuous Monitoring (MON) efforts are requirements-driven and governed at a local/regional level, but are not consistent across the organization. CMM Level 2 control maturity would reasonably expect all, or at least most, the following criteria to exist: o Identify cybersecurity and data protection controls that are appropriate to address applicable statutory, regulatory and contractual requirements for situational awareness management. o Configure alerts for critical or sensitive data that is stored, transmitted and processed on assets. o Use a structured process to review and analyze logs.
- Situational awareness management is decentralized (e.g., a localized/regionalized function) and uses non-standardized methods to implement secure, resilient and compliant practices.
- Secure baseline configurations generate logs that contain sufficient information to establish necessary details of activity and allow for forensics analysis.
- IT/cybersecurity personnel:
- A log aggregator, or similar automated tool, provides an event log report generation capability to aid in detecting and assessing anomalous activities on business-critical systems.
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
See C|P-CMM3. There are no defined C|P-CMM4 criteria, since it is reasonable to assume a quantitatively-controlled process is not necessary to monitor sensitive/regulated data in Technology Assets, Applications and/or Services (TAAS) and data repositories.
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 monitor sensitive/regulated data in Technology Assets, Applications and/or Services (TAAS) and data repositories.
Assessment Objectives
- MON-18_A01 automated tools are used to monitor sensitive/regulated data in Assets, Applications & Services (AAS).
- MON-18_A02 automated tools are used to monitor sensitive/regulated data in data repositories.
