Compliance — NIST SP 800-53
NIST SP 800-53 Rev 5 — AU and SI families covered continuously
NIST SP 800-53 Rev 5 underpins FedRAMP, FISMA, and DoD RMF authorisations. ManySignal addresses the Audit and Accountability (AU) and System and Information Integrity (SI) control families in full — with OSCAL-compatible evidence for eMASS submission and monthly CA-7 ConMon reporting.
Control mapping — NIST SP 800-53 to ManySignal
| Control ID | Control Name | ManySignal Capability |
|---|---|---|
| AU-2 | Event Logging | Configurable event types per system — OS, application, network, and identity events with coverage reporting |
| AU-6 | Audit Record Review, Analysis, and Reporting | Automated daily audit record analysis with anomaly alerting and weekly summary reports |
| AU-9 | Protection of Audit Information | Tamper-evident log storage — audit record modification triggers immediate alert |
| AU-12 | Audit Record Generation | Centralised audit record generation from all system boundary components |
| SI-4 | System Monitoring | Continuous real-time monitoring across all system boundary assets — network, endpoint, identity, and cloud |
| SI-4(2) | Automated Tools and Mechanisms | ML-based behavioural analytics and signature-based detection operating continuously |
| SI-4(4) | Inbound and Outbound Communications Traffic | Network flow analysis — East-West and North-South traffic anomaly detection |
| SI-4(5) | System-Generated Alerts | Real-time alert generation with confidence scores and triage agent verdicts |
| IR-4 | Incident Handling | Automated incident lifecycle — detection, containment, evidence collection, and documentation |
| IR-5 | Incident Monitoring | Case lifecycle tracking with full timeline, entity list, and analyst action log |
| IR-6 | Incident Reporting | FISMA/US-CERT incident reporting support — case records formatted for reporting requirements |
| CA-7 | Continuous Monitoring | Monthly ConMon reporting evidence — coverage, anomalies detected, incidents opened, and POA&M updates |

NIST SP 800-53 — common questions
How does ManySignal support NIST SP 800-53 Rev 5 versus Rev 4?
ManySignal maps to NIST SP 800-53 Rev 5 (September 2020), which is the current version required by FedRAMP Moderate and High baselines. Rev 5 added privacy controls (PT family) and supply chain risk management (SR family). ManySignal addresses the monitoring-relevant control families in full for Rev 5, including the updated SI-4 system monitoring controls and the revised AU audit controls.
Can ManySignal generate OSCAL-compatible output for eMASS submissions?
ManySignal's evidence export includes OSCAL (Open Security Controls Assessment Language) compatible output for AU and SI control families. This enables direct upload to eMASS (Enterprise Mission Assurance Support Service) for federal system authorizations and supports automated ConMon reporting workflows used by many federal agencies.
How does ManySignal address CA-7 Continuous Monitoring specifically?
CA-7 requires an organisation-wide continuous monitoring programme with defined monitoring frequencies. ManySignal provides: (1) real-time monitoring of all system boundary components; (2) monthly ConMon summary reports listing anomalies detected, alerts fired, incidents opened, and POA&M items updated; (3) annual security control assessment evidence showing the monitoring controls operated correctly throughout the year.
Does ManySignal support the High baseline or just Moderate baseline controls?
ManySignal supports both FedRAMP Moderate and High baseline controls. The High baseline adds additional AU and SI control enhancements — including AU-9(5) (dual authorization for audit record modification), SI-4(10) (visibility into encrypted communications), and SI-4(18) (correlation of monitoring information). ManySignal's High baseline deployment configuration addresses these enhancement requirements.
Can ManySignal integrate with an existing SIEM for agencies that have a SIEM investment?
Yes. ManySignal operates as a SIEM augmentation layer — it ingests data from your existing SIEM (Splunk, IBM QRadar, Microsoft Sentinel) and applies AI-powered analytics on top of it. For agencies with an existing SIEM investment, ManySignal adds the AI triage, behavioural analytics, and automated response capabilities that conventional SIEMs lack, without requiring replacement of the existing architecture.
