(https://www.icompaas.com) **NIST SP 800-53 Rev. 5**·Control `SI-4(16)`·high·Component: **System and Information Integrity** ## What this control requires > Correlate information from various monitoring tools and mechanisms employed throughout the system to create a comprehensive view of system activity. By integrating tools like malicious code protection, host monitoring, and network monitoring, organizations can uncover previously hidden attack patterns. This helps in developing a more effective system-wide monitoring program, especially during transitions to newer technologies such as IPv6. This control supports the System-Wide Monitoring Correlation Engine capability within the System and Information Integrity family. > > — NIST SP 800-53 Rev. 5, Control SI-4(16) ### In plain English Correlate information from various monitoring tools and mechanisms employed throughout the system to create a comprehensive view of system activity. In practice, this means you can prove you information information-level controls on a defined cadence. ## Why it matters SP 800-53 is the catalogue every U.S. federal authorisation (FedRAMP, FISMA, CMMC) and most regulated industries point at. A missing control surfaces as a Plan of Action & Milestones (POA&M) item that an Authorizing Official must approve before the Authority To Operate is granted or renewed. This control is rated **high**. Auditors expect a named owner, a remediation SLA, and a tooling artefact that evidences continuous operation. ## What an auditor looks for A 3PAO (FedRAMP) or Independent Assessor (NIST RMF) tests against NIST SP 800-53A assessment procedures. For each control they expect a documented implementation that addresses every assessment objective (Examine, Interview, Test) and an implementation summary in the System Security Plan. Within **System and Information Integrity**, the assessor will trace your implementation back to the catalogue reference (Control SI-4(16)) and look for objective evidence on the latest two assessment cycles. ## How to implement #### Secure Development **Pipeline.** Require code review, SAST (Semgrep / Snyk Code), SCA (Dependabot / Renovate), secret-scanning and IaC scanning in the merge pipeline. **Branch protection.** Protected branches enforce reviews, signed commits and passing CI before merge; document the protection rules as the control evidence. #### Code Review Testing **Pipeline.** Require at least one human reviewer plus passing CI (lint, type, unit, security scan) before merge — protected branches enforce this. ### Operational checklist - **Information.** Document the trigger, the owner and the cadence. - **Security.** Document the trigger, the owner and the cadence. - **Network.** Document the trigger, the owner and the cadence. - **Review.** Document the trigger, the owner and the cadence. - **Protection.** Document the trigger, the owner and the cadence. - **Scope:** information, system, application, protection, review, capability, correlation, tools. ## Evidence to collect - **Code Repo Scan.** Source-control evidence — branch protection, required reviewers, CI status, SCA / SAST reports. Source control pipelines (GitHub, GitLab) enforce SDLC guardrails. Focus: Correlate Monitoring Information. ## Common pitfalls - CI security checks set to warn-only; the merge button is faster than the security feedback. ## How it maps to other frameworks Computed from shared tags, control component and key-operation subjects — handy when you are reconciling controls across an audit. - [**NIST SP 800-171 Rev. 3 3.13.13** — Mobile Code](https://support.icompaas.com/compliance/nist-sp-800-171-rev-3/3-13-13-mobile-code) - [**CIS Controls v8 16.12** — Implement Code-Level Security Checks](https://support.icompaas.com/compliance/cis-controls-v8/16-12-implement-code-level-security-checks) - [**BSI C5:2020 OPS-17** — Logging and Monitoring - Availability of the Monitoring Software](https://support.icompaas.com/compliance/bsi-c5-2020/ops-17-logging-and-monitoring-availability-of-the-monitoring-software) ## Related controls in NIST SP 800-53 Rev. 5 - [**Control SI-7(6)** — Cryptographic Protection](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/si-7-6-cryptographic-protection) - [**Control SI-3(6)** — Testing And Verification](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/si-3-6-testing-and-verification) - [**Control SI-8(3)** — Continuous Learning Capability](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/si-8-3-continuous-learning-capability) - [**Control SI-7(15)** — Code Authentication](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/si-7-15-code-authentication) - [**Control SI-3** — Malicious Code Protection](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/si-3-malicious-code-protection) - [**Control SI-4(4)** — Inbound And Outbound Communications Traffic](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/si-4-4-inbound-and-outbound-communications-traffic) ## References - [NIST Computer Security Resource Center — NIST SP 800-53 Rev. 5](https://csrc.nist.gov/Projects/risk-management/sp800-53-controls) - Catalogue identifier: `Control SI-4(16)` Topics: application securitylogging monitoringsecure developmentcode review testingdevsecopscontinuous monitoring ## Related compliance guidance - [NIST SP 800-53 Rev. 5: a practical implementation guide for cloud teams](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5): Start with the full NIST SP 800-53 implementation guide — scope, roadmap, evidence and how the assessment runs. - [NIST SP 800-171 and CMMC: a practical guide to protecting CUI in the cloud](https://support.icompaas.com/compliance/nist-sp-800-171-rev-3): If your obligation is protecting CUI in your own systems for a federal or defence contract, this derived subset — not the full catalogue — is the requirement. - [SOC 2 compliance: a practical implementation guide for cloud-native SaaS teams](https://support.icompaas.com/compliance/soc-2-trust-services-criteria): Most commercial SaaS already hold a SOC 2 Type 2, and FedRAMP 20x Class A is designed for providers that have one.
