Requirements NIST SOURCE

Employ trend analyses to determine if control implementations, the frequency of continuous monitoring activities, and the types of activities used in the continuous monitoring process need to be modified based on empirical data.

Discussion (NIST Supplemental Guidance)

Trend analyses include examining recent threat information that addresses the types of threat events that have occurred in the organization or the Federal Government, success rates of certain types of attacks, emerging vulnerabilities in technologies, evolving social engineering techniques, the effectiveness of configuration settings, results from multiple control assessments, and findings from Inspectors General or auditors.

Assessment

NIST SP 800-53A REV 5.2.0

Assessment Objectives

  1. trend analysis is employed to determine if control implementations used in the continuous monitoring process need to be modified based on empirical data;
  2. trend analysis is employed to determine if the frequency of continuous monitoring activities used in the continuous monitoring process needs to be modified based on empirical data;
  3. trend analysis is employed to determine if the types of activities used in the continuous monitoring process need to be modified based on empirical data.

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for CA-7(3). This section is architected to display, per product: STIG ID, Finding ID, Severity, Title, Description, Check, Fix, CCI, and NIST control mapping — but nothing is populated here until a real DISA STIG/CCI dataset is ingested.
