Assessment Objective

Determine if:

• SI-04a.
  • SI-04a.01 the system is monitored to detect attacks and indicators of potential attacks in accordance with [Assignment: monitoring objectives];
  • SI-04a.02
    • SI-04a.02[01] the system is monitored to detect unauthorized local connections;
    • SI-04a.02[02] the system is monitored to detect unauthorized network connections;
    • SI-04a.02[03] the system is monitored to detect unauthorized remote connections;
• SI-04b. unauthorized use of the system is identified through [Assignment: techniques and methods];
• SI-04c.
  • SI-04c.01 internal monitoring capabilities are invoked or monitoring devices are deployed strategically within the system to collect organization-determined essential information;
  • SI-04c.02 internal monitoring capabilities are invoked or monitoring devices are deployed at ad hoc locations within the system to track specific types of transactions of interest to the organization;
• SI-04d.
  • SI-04d.[01] detected events are analyzed;
  • SI-04d.[02] detected anomalies are analyzed;
• SI-04e. the level of system monitoring activity is adjusted when there is a change in risk to organizational operations and assets, individuals, other organizations, or the Nation;
• SI-04f. a legal opinion regarding system monitoring activities is obtained;
• SI-04g. [Assignment: system monitoring information] is provided to [Assignment: personnel or roles] [Selection (one or more): as needed; [Assignment: frequency] ].

Assessment Methods

Examine

• System and information integrity policy
• system and information integrity procedures
• procedures addressing system monitoring tools and techniques
• continuous monitoring strategy
• facility diagram/layout
• system design documentation
• system monitoring tools and techniques documentation
• locations within the system where monitoring devices are deployed
• system configuration settings and associated documentation
• system security plan
• other relevant documents or records

Interview

• System/network administrators
• organizational personnel with information security responsibilities
• organizational personnel installing, configuring, and/or maintaining the system
• organizational personnel responsible for monitoring the system

Test

• Organizational processes for system monitoring
• mechanisms supporting and/or implementing system monitoring capabilities
