(https://www.icompaas.com) **NIST SP 800-53 Rev. 5**·Control `SI-4(5)`·high·Component: **System and Information Integrity** ## What this control requires > Alert designated personnel when system-generated indicators of compromise or potential compromise occur. These alerts may come from sources like audit records, malicious code protection mechanisms, intrusion detection or prevention systems, or boundary protection devices. Alerts can be automated and transmitted via various channels, such as email, phone, or text. This control supports the Intrusion Detection Systems (IDS), Firewalls, Email Servers capability within the System and Information Integrity family. > > — NIST SP 800-53 Rev. 5, Control SI-4(5) ### In plain English Alert designated personnel when system-generated indicators of compromise or potential compromise occur. In practice, this means you can prove you audit email-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(5)) and look for objective evidence on the latest two assessment cycles. ## How to implement #### Endpoint Protection **MDM.** Make MDM enrollment a hard gate for device access (Intune compliance + Conditional Access, or Jamf + Okta device trust). Unmanaged devices simply don't get a session token. **EDR.** Deploy CrowdStrike / SentinelOne / Defender for Endpoint to every server and laptop; alert on any host that stops sending telemetry for >24h. #### Logging Monitoring **AWS.** Org-trail CloudTrail to a central log archive account, GuardDuty in every region, and Security Hub for cross-source correlation. **Azure.** Pipe every diagnostic setting into a central Log Analytics workspace; onboard Microsoft Sentinel for SIEM/SOAR. **GCP.** Aggregate audit logs in a dedicated logging project with sink to BigQuery; enable Security Command Center Premium and route findings to Chronicle SIEM. ### Operational checklist - **Audit.** Document the trigger, the owner and the cadence. - **Information.** Document the trigger, the owner and the cadence. - **Security.** Document the trigger, the owner and the cadence. - **Detection.** Document the trigger, the owner and the cadence. - **Protection.** Document the trigger, the owner and the cadence. - **Scope:** email, information, system, personnel, records, audit records, alerts, protection. ## Evidence to collect - **User Device Scan.** MDM compliance state per user device (Intune / Jamf / Workspace ONE). Endpoint compliance telemetry (Intune, Jamf) proves managed coverage. Focus: System-Generated Alerts. ## Common pitfalls - Pilot MDM rollouts that quietly exclude executives or engineers; carving out the highest-risk users is the most common audit failure. - Per-account logging that nobody stitches together at the org level — incidents that cross accounts go undetected for days. ## Related controls in NIST SP 800-53 Rev. 5 - [**Control SI-4(13)** — Analyze Traffic And Event Patterns](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/si-4-13-analyze-traffic-and-event-patterns) - [**Control SI-4** — System Monitoring](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/si-4-system-monitoring) - [**Control SI-4(23)** — Host-Based Devices](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/si-4-23-host-based-devices) - [**Control SI-4(9)** — Testing Of Monitoring Tools And Mechanisms](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/si-4-9-testing-of-monitoring-tools-and-mechanisms) - [**Control SI-4(14)** — Wireless Intrusion Detection](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/si-4-14-wireless-intrusion-detection) - [**Control AC-17(1)** — Monitoring And Control](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/ac-17-1-monitoring-and-control) ## 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(5)` Topics: endpoint securitylogging monitoringendpoint protection ## 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.
