03.14 — System and Information Integrity · NIST SP 800-172 Revision 3

Active
Official NIST requirement content

Security requirement

Alert [Organization-defined: personnel or roles] using [Organization-defined: automated mechanisms] when the following indications of inappropriate or unusual activities with security implications occur: [Organization-defined: activities].

Official NIST discussion

Discussion

Organization-generated alerts are focused on information sources that are external to the system, such as suspicious activity reports and reports on potential insider threats. Organizational personnel on the system alert notification list include system administrators, mission or business owners, system owners, chief information security officers, and system security officers. This requirement enhances SP 800-171 requirement 03.14.06.

Official organization-defined parameters

Tailoring decisions required

Resolve these values through the governing organization’s approved tailoring and risk-management process before declaring the requirement implemented.

Official protection strategy classifications

Protection strategies supported

These classifications are carried from the official SP 800-172 OSCAL record and help explain the enhanced requirement’s defensive purpose.

Bare Metal Cyber interpretation

Implementation perspective

Treat Automated Organization-Generated Alerts as an enhanced CUI protection outcome for elevated threat conditions that must be reflected in the system boundary, documented implementation, operational behavior, and assessment evidence. Pay particular attention to flaw remediation, malicious-code protection, monitoring, integrity, and trustworthy handling of CUI.

  1. Confirm the federal agency selected this enhanced requirement for the critical program or high-value asset and identify the CUI system components, services, users, and external connections in scope.
  2. Resolve every organization-defined parameter through an approved governance and tailoring process.
  3. Map each clause of the requirement to an accountable owner, implementation mechanism, and evidence source.
  4. Verify that inherited and shared implementations are supported by current provider evidence and responsibility boundaries.
  5. Collect evidence during normal operation and review changes, exceptions, and deficiencies on a risk-based cadence.

Questions to ask

  • Which critical-program or high-value-asset CUI, data flows, users, and services are protected by this enhanced requirement?
  • Which portions are implemented locally, inherited, shared, or not applicable, and what evidence supports that determination?
  • Do the system security plan, deployed configuration, operating process, and assessment evidence tell the same story?
  • What change, incident, or threshold should trigger reassessment?

Evidence and validation

  • patch and remediation records
  • malware protection configuration
  • monitoring alerts and response records
  • integrity validation and exception reports

Common failure patterns

  • patch compliance hiding unsupported assets
  • alerts generated without response ownership
  • exceptions that never expire
  • integrity monitoring excluding critical configurations

Assessment objectives and methods

Assessment objectives (1)
  1. [Organization-defined: personnel or roles] are alerted using [Organization-defined: automated mechanisms] when [Organization-defined: activities] indicate inappropriate or unusual activities with security implications.

Examine

  • System and information integrity policy
  • system and information integrity procedures
  • system security plan
  • list of inappropriate or unusual activities with security implications that trigger alerts
  • suspicious activity reports
  • system monitoring tools and techniques documentation
  • system design documentation
  • procedures addressing system monitoring tools and techniques
  • alerts provided to security personnel
  • system configuration settings and associated documentation
  • system monitoring logs or records
  • system audit records
  • other relevant documents or records

Interview

  • Personnel with information security responsibilities
  • system developers
  • personnel installing, configuring, and/or maintaining the system
  • personnel responsible for monitoring the system
  • personnel responsible for the intrusion detection system
  • system/network administrators

Test

  • Processes for intrusion detection and system monitoring
  • automated mechanisms supporting and/or implementing intrusion detection and system monitoring capabilities
  • automated mechanisms supporting and/or implementing automated alerts to security personnel
