    Study Notes

    Monitoring Points

    • Data from all security events must be sent to a collection server in the Red Management Network and may be fed into the Red SIEM solution.
    • For deployments where the MP5 is implemented, network monitoring data must be collected from the chosen monitoring solution.
    • The monitoring capability must log all traffic outside of expected traffic for the Outer Encryption Component.
    • Network flow data from the Red Network must be collected from the Inner Firewall and sent to a collection server in the Red Management Network.
    • Deep packet inspection is feasible for MPs deployed in the Red Network.
    • Monitoring capabilities at MP6 include vulnerability scanning tools, network scanning capabilities, and similar tools to monitor security posture and configuration compliance.
    • Reports generated from monitoring tools should be sent to SIEM solutions and reviewed on an as AO defined interval.

    Monitoring Point 6 (MP6)

    • Located within the Gray Management Network to monitor the management network deployed in the Gray Network.
    • MP6 is required in all CSfC CM Solutions.
    • The collected data for MP6 must provide security administrators visibility of all network and system behavior on the Gray Management Network.
    • Data collected at MP6 may include system log data, network flow data from the Outer Encryption Component and Gray Firewall, Network Tap traffic, IDS/IPS notifications, inline IDS/IPS traffic/notifications, and span port or port mirroring.

    Monitoring Point Requirements

    • Monitoring point requirements are identified by a label consisting of the prefix "CM" a two-letter category, and a sequence number (e.g., CM-MP1-3).
    • Each CSfC CP requires a set of required MPs along with at least two other remaining monitoring points from different networks.

    MP1 Requirements

    • Only apply these requirements to the solution if MP1 is implemented.
    • The monitoring capability must log any unauthorized attempts to scan the Outer Encryption Component or Outer Firewall.

    MP2 Requirements

    • The monitoring capability must log any attempt to scan the EUD/Encryption Components, Outer Encryption Component, Gray Firewall/Encryption Component, Inner Encryption Component, or Gray Data services.

    MP3 Requirements

    • Only apply these requirements to the solution if MP3 is implemented.
    • The monitoring capability must log when a system generates an excessive number of short packets.

    MP5 Requirements

    • The monitoring capability must log any attempt to scan the EUD/Encryption Components, Inner Encryption Component, Inner Firewall or Red Data Network.

    MP6 Requirements

    • Applies to all CSfC solutions.
    • The Gray Authentication services, Gray Network components and Gray Management services must log any failed login attempt.
