Inbound & Outbound Communications Traffic
Description
Mechanisms exist to continuously monitor inbound and outbound communications traffic for unusual or unauthorized activities or conditions.
Possible Solutions & Considerations
Micro-Small Business (<10 staff) / BLS Firm Size Classes 1-2
∙ Intrusion Detection / Prevention Systems (IDS / IPS)
Small Business (10-49 staff) / BLS Firm Size Classes 3-4
∙ Intrusion Detection / Prevention Systems (IDS / IPS)
Medium Business (50-249 staff) / BLS Firm Size Classes 5-6
∙ Intrusion Detection / Prevention Systems (IDS / IPS)
∙ Extended Detection and Response (XDR)
Large Business (250-999 staff) / BLS Firm Size Classes 7-8
∙ Intrusion Detection / Prevention Systems (IDS / IPS)
∙ Extended Detection and Response (XDR)
Enterprise (> 1,000 staff) / BLS Firm Size Class 9
∙ Intrusion Detection / Prevention Systems (IDS / IPS)
∙ Extended Detection and Response (XDR)
SCR-CMM
Level 0 Not Performed
Practices are non-existent, based on the inability to demonstrate an implemented and operational capability. A reasonable person would conclude the control is not being performed.
Level 1 Performed Informally
Continuous Monitoring (MON) domain capabilities are ad hoc and inconsistent. Capability criteria associated with this control may include:
▪ Policies, standards & procedures associated with MON domain capabilities provide limited coverage due to the depth and breadth of the existing documentation.
▪ Event monitoring-related activities are decentralized (e.g., a localized/regionalized function) and uses non-standardized methods to implement secure, resilient and compliant practices.
▪ Monitoring is primarily reactive in nature, focused on identifying incidents that occurred.
▪ Event log reviews primarily rely on manual processes to identify anomalous behaviors.
▪ Generating event logs and the review of those event logs is narrowly-focused to business-critical Technology Assets, Applications, Services and/or Data (TAASD).
Level 2 Planned Tracked
Continuous Monitoring (MON) capabilities are requirements-driven, but are not standardized across the entity (e.g., local/regional level consistency). Capability criteria associated with this control reasonably expect the following criteria to exist:
▪ Policies and standards associated with MON domain capabilities are formally documented and centrally-managed by the entity.
▪ Standardized Operating Procedures (SOP) associated with MON domain capabilities are documented and maintained by process owners.
▪ IT and/or cybersecurity personnel work with business stakeholders and process owners to appropriately scope and reasonably implement cybersecurity and data protection controls associated with MON domain capabilities to address applicable statutory, regulatory and/or contractual requirements for Technology Assets, Applications, Services and/or Data (TAASD).
▪ Continuous monitoring-related controls are primarily administrative and preventative in nature (e.g., policies, standards and procedures & guidelines).
▪ Continuous monitoring may be a defined function (e.g., team or department) or assigned as an additional duty to existing IT and/or cybersecurity personnel.
Level 3 Well Defined
Continuous Monitoring (MON) capabilities are standardized across the entity for applicability to People, Processes, Technologies, Data and/or Facilities (PPTDF) to ensure consistency for Technology Assets, Applications, Services and/or Data (TAASD). Capability criteria associated with this control reasonably expect the following criteria to exist:
▪ Policies and standards associated with MON domain capabilities are formally documented and centrally-managed by the entity's Governance, Risk & Compliance (GRC) team, or similar function.
▪ Cybersecurity personnel use a structured process via Standardized Operating Procedures (SOP) to review and analyze logs.
▪ A Security Operations Center (SOC) team, or similar function, is appropriately staffed and supported to implement and maintain MON domain capabilities.
▪ Technology is leveraged to enhance the efficiency and accuracy of continuous monitoring operations (e.g., Security Incident Event Manager (SIEM)).
▪ The entity's Governance, Risk & Compliance (GRC) team, or similar function, works with business stakeholders and process owners to appropriately scope and reasonably implement cybersecurity and data protection controls associated with MON domain capabilities to address Minimum Compliance Requirements (MCR) (e.g., applicable statutory, regulatory and/or contractual requirements) and Discretionary Security Requirements (DSR) (e.g., entity-required controls).
▪ Secure Baseline Configurations (SBC) enforce security event logging to contain sufficient information to establish necessary details of activity and allow for forensics analysis.
▪ An implemented and operational capability exists to continuously monitor inbound and outbound communications traffic for unusual or unauthorized activities or conditions.
Level 4 Quantitatively Controlled
Utilize SCR-CMM Level 3 criteria definitions:
▪ There are no defined Level 4 criteria, since it is reasonable to assume a quantitatively-controlled process is not necessary to operationalize this control.
▪ While it may be possible to develop “metrics-driven” capabilities for this control, the criteria would be organization-specific to define.
Level 5 Continuously Improving
Utilize SCR-CMM Level 3 or Level 4 (if available) criteria definitions:
▪ There are no defined Level 5 criteria, since it is reasonable to assume a continuously-improving process is not necessary to operationalize this control.
▪ Level 5 capabilities should be considered “world-class” where the control builds on Level 4 capabilities, but are continuously improving through Artificial Intelligence (AI) and/or Machine Learning (ML) technologies.
▪ While it may be possible to develop responsive capabilities for this control through the use of AI and/or ML technologies, the criteria would be organization-specific to define.

Proxy Logging
|
Description
Mechanisms exist to log all Internet-bound requests, in order to identify prohibited activities and assist incident handlers with identifying potentially compromised systems.
Possible Solutions & Considerations
Micro-Small Business (<10 staff) / BLS Firm Size Classes 1-2
∙ Review system logs periodically
Small Business (10-49 staff) / BLS Firm Size Classes 3-4
∙ Log monitoring policy
∙ Regular review of key system logs
Medium Business (50-249 staff) / BLS Firm Size Classes 5-6
∙ SIEM (e.g., Wazuh)
∙ Automated log collection and alerting
Large Business (250-999 staff) / BLS Firm Size Classes 7-8
∙ Enterprise SIEM (e.g., Splunk, IBM QRadar)
∙ Continuous monitoring program
∙ SOC monitoring
Enterprise (> 1,000 staff) / BLS Firm Size Class 9
∙ Enterprise SIEM/SOAR platform
∙ 24/7 SOC monitoring
∙ Threat hunting
∙ Automated incident response
