These mechanisms should be used at an organization-defined frequency to track and determine the status of known flaws for system components. This control supports the System Integrity Controls capability within the System and Information Integrity family. > > — NIST SP 800-53 Rev. 5, Control SI-2(2) ### In plain English Determine if system components have applicable security-relevant software and firmware updates installed using automated mechanisms. In practice, this means you can prove you security-relevant management-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-2(2)) and look for objective evidence on the latest two assessment cycles. ## How to implement #### Cloud Posture **CSPM.** Run Wiz / Prisma / Defender for Cloud / Security Command Center over every account; auto-ticket findings above your accepted-risk threshold. #### Configuration Management **Policy-as-code.** Codify the control as Service Control Policies (AWS), Azure Policy initiatives, or Organisation Policy (GCP) so the platform enforces what the document promises. **IaC.** Gate Terraform / Pulumi / CloudFormation changes with Checkov / tfsec / OPA so misconfigurations never reach production. **Drift.** Run a CSPM (Wiz / Prisma / Defender for Cloud / Security Command Center) over every account and route findings to a single risk register. #### Network Security **AWS.** VPC Flow Logs to S3, default-deny security groups, AWS Network Firewall for north-south, and Transit Gateway for hub-and-spoke segmentation. **Azure.** NSGs with deny-by-default, Azure Firewall Premium with TLS inspection, Private Endpoints for PaaS, and Microsoft Defender for Cloud's secure score for drift. **GCP.** VPC Service Controls perimeters around sensitive APIs, Cloud NGFW Enterprise for L7 inspection, Private Service Connect for managed services. ### Operational checklist - **Security-Relevant.** Document the trigger, the owner and the cadence. - **Information.** Document the trigger, the owner and the cadence. - **Configuration.** Document the trigger, the owner and the cadence. - **Network.** Document the trigger, the owner and the cadence. - **System.** Document the trigger, the owner and the cadence. - **Scope:** management, information, organization, system, controls, configuration, software, firmware. ## Evidence to collect - **Infra Scan.** Continuous infrastructure-posture telemetry — AWS Config, Azure Policy compliance, GCP Organisation Policy, Wiz / Prisma findings. Infrastructure posture tooling (AWS Config, Azure Policy, Nessus) verifies platform hardening. Focus: Automated Flaw Remediation Status. ## Common pitfalls - Treating CSPM findings as a backlog instead of a hot queue: findings older than the policy SLA accumulate until the auditor asks why. - Manual cloud-console changes that never make it back to Terraform — drift accumulates until the next outage forces a reconciliation. - Default-allow egress rules; East-West traffic with no segmentation; jump hosts on the public internet with password auth. ## 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. - [**ISO/IEC 27001:2022 A.5.34** — Privacy and protection of personal identifiable information (PII)](https://support.icompaas.com/compliance/iso-27001-2022/a-5-34-privacy-and-protection-of-personal-identifiable-information-pii) - [**NIST SP 800-171 Rev. 3 3.4.12** — System and Component Configuration for High-Risk Areas](https://support.icompaas.com/compliance/nist-sp-800-171-rev-3/3-4-12-system-and-component-configuration-for-high-risk-areas) - [**BSI C5:2020 PSS-04** — Error handling and Logging Mechanisms](https://support.icompaas.com/compliance/bsi-c5-2020/pss-04-error-handling-and-logging-mechanisms) ## Related controls in NIST SP 800-53 Rev. 5 - [**Control SI-2(5)** — Automatic Software And Firmware Updates](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/si-2-5-automatic-software-and-firmware-updates) - [**Control SI-2** — Flaw Remediation](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/si-2-flaw-remediation) - [**Control SI-8** — Spam Protection](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/si-8-spam-protection) - [**Control SC-30(4)** — Misleading Information](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/sc-30-4-misleading-information) - [**Control SC-8(3)** — Cryptographic Protection For Message Externals](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/sc-8-3-cryptographic-protection-for-message-externals) - [**Control CP-9(3)** — Separate Storage For Critical Information](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/cp-9-3-separate-storage-for-critical-information) ## 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-2(2)` Topics: cloud infrastructurecloud postureconfiguration managementnetwork security ## 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.
