Identify, report, and correct system flaws and security threats — 7 requirements covering 21 total SPRS points.
The System and Information Integrity domain requires organizations to identify and correct system flaws in a timely manner, protect against malicious code, monitor systems for security alerts and anomalies, and maintain the integrity of CUI-handling systems. Malware, unpatched vulnerabilities, and unauthorized changes are the immediate operational threats to CUI integrity. Patch management failures and absent anti-malware protection are among the most consistently cited findings in DIB cybersecurity assessments.
Every NIST SP 800-171 Rev 2 requirement in the SI family, with SPRS point weight and POA&M eligibility.
| Requirement | Description | Points | POA&M |
|---|---|---|---|
| SI.L2-3.14.1 | Identify, report, and correct information and information system flaws in a timely manner. | 5 | Conditional |
| SI.L2-3.14.2 | Provide protection from malicious code at appropriate locations within organizational systems. | 5 | Conditional |
| SI.L2-3.14.3 | Monitor system security alerts and advisories and take action in response. | 5 | Conditional |
| SI.L2-3.14.4 | Update malicious code protection mechanisms when new releases are available. | 5 | Conditional |
| SI.L2-3.14.5 | Perform periodic scans of organizational systems and real-time scans of files from external sources as files are downloaded, opened, or executed. | 3 | Yes |
| SI.L2-3.14.6 | Monitor organizational systems, including inbound and outbound communications traffic, to detect attacks and indicators of potential attacks. | 5 | Conditional |
| SI.L2-3.14.7 | Identify unauthorized use of organizational systems. | 3 | Yes |
Identify, log, and track system flaws from discovery through remediation. Automated workflows assign owners, set deadlines, and capture evidence that 3.14.1 requires for timely correction.
Monitor antivirus and endpoint protection deployments across your environment. Track update status, scan schedules, and detection events to demonstrate compliance with 3.14.2, 3.14.4, and 3.14.5.
Aggregate security alerts and advisories from vendor sources, CISA, and NVD. Track response actions and document your organization's handling of each advisory to satisfy 3.14.3.
Document your monitoring architecture for inbound and outbound traffic, capture indicators of compromise, and maintain detection logs that demonstrate 3.14.6 compliance during assessment.
Define baseline system usage patterns and document how your organization identifies unauthorized activity. Link detection mechanisms to alerting workflows for complete 3.14.7 evidence.
Automate file integrity monitoring, configuration drift detection, and system health checks. Centralized reporting ties integrity events back to specific requirements for assessment readiness.
These tools are commonly used by defense contractors to satisfy SI requirements. During your C3PAO assessment, you'll document exactly which tools satisfy each control.
Assessors will check that anti-malware is deployed on all CUI-handling systems and verify that signature updates are current. They'll review patch management practices and ask for evidence that critical patches are applied within your documented timeframes. Expect questions about how you receive and act on security alerts.
System integrity is the difference between detecting a breach in hours and discovering it in months. By the time CUI has been exfiltrated, compliance is the least of your problems.
