SI-8(1): Central Management

Compliance teams usually understand “run anti-malware” as a generic expectation. SI-8(1): Central Management is narrower and more operational: it focuses on how you manage the anti-malware program, not whether a single machine has an agent installed. Auditors look for centralized control planes, standardized configurations, and a repeatable way to confirm that endpoints and servers stay protected over time.

This requirement becomes urgent in hybrid environments where some systems sit on corporate networks, some are remote, and some are hosted by cloud and managed service providers. Decentralized administration leads to inconsistent exclusions, delayed signature updates, and gaps in alerting. Those gaps create two problems at once: higher incident likelihood and weaker audit defensibility.

This page gives requirement-level implementation guidance for the si-8(1): central management requirement, written for a Compliance Officer, CCO, or GRC lead. The goal is simple: set clear ownership, implement central controls that actually enforce configuration, and build an evidence set that survives an assessment without a fire drill.

What SI-8(1): Central Management means (plain English)

SI-8(1) is an enhancement to SI-8 (Malicious Code Protection). The practical expectation is:

• You manage anti-malware centrally (configuration, updates, policy enforcement, reporting).
• You reduce local discretion that can weaken protection (for example, ad hoc exclusions).
• You can demonstrate coverage and health from a central view, across the in-scope system boundary.

In an audit, “central management” is usually interpreted as a single authoritative management plane (or tightly governed set of management planes) that can:

• Push policy to endpoints/servers/workloads,
• Confirm receipt and compliance,
• Alert on unhealthy agents, out-of-date signatures, and tamper events,
• Produce evidence without logging into individual machines.

Regulatory text

The provided excerpt is: “NIST SP 800-53 control SI-8.1.” ¹

Operator translation: you need a defined, implemented, and operating method to centrally administer and monitor malicious code protection for the system. The control is not satisfied by stating “IT installs antivirus.” You must show that administration and oversight are centralized, consistent, and sustained.

Who it applies to

Entities

• Federal information systems.
• Contractors and service providers handling federal data or operating federal systems, including cloud-hosted workloads and managed endpoints. ²

Operational contexts where auditors focus on SI-8(1)

• Mixed OS fleets (Windows, macOS, Linux).
• Remote workforce with intermittent connectivity.
• Cloud IaaS/PaaS workloads and containers.
• Subsidiaries or business units with historically separate IT.
• Third parties managing endpoints or hosting systems (MSPs, managed SOCs, desktop support vendors).

System scope Apply SI-8(1) to the defined authorization boundary or system boundary you use for NIST 800-53 alignment. If you don’t have a clean boundary definition, central management becomes hard to prove because “coverage” cannot be measured.

What you actually need to do (step-by-step)

Use this sequence to implement and document SI-8(1) quickly.

1) Assign ownership and define “central” for your environment

• Name a control owner (typically Endpoint Security, SecOps, or Security Engineering).
• Define the approved central management platforms (example: EDR/AV console(s), MDM for mobile endpoints, server management tooling).
• Document which platform governs which asset types and OS families. Deliverable: a one-page control implementation statement mapped to tooling and responsibilities.

2) Inventory and coverage mapping (the make-or-break step)

• Start from your asset inventory (CMDB, MDM inventory, EDR inventory).
• Create a coverage map by asset class:
  • End-user endpoints
  • Servers
  • VDI
  • Cloud instances
  • Build systems (CI runners)
• Identify “can’t run an agent” classes (some appliances, certain PaaS) and document compensating protections where applicable. Evidence goal: you can reconcile “in-scope assets” vs “protected assets” without manual spreadsheets.

3) Standardize your anti-malware configuration baseline

Define baselines that the central console enforces:

• Real-time protection settings
• Scan schedules (if used in your operating model)
• Tamper protection / uninstall protection
• Quarantine and remediation actions
• Logging and telemetry forwarding to your SIEM (or security logging platform)
• Exclusion governance (who can request, who approves, expiration and review) Treat baselines as configuration-controlled items under your change process.

4) Centralize updates and policy deployment

• Ensure signatures/engines/rules update via centrally managed channels.
• Confirm remote and off-network devices still update (cloud relay, VPN requirement, or direct internet update with policy enforcement).
• Prevent local users/admins from disabling protection outside approved break-glass paths.

5) Implement centralized monitoring and reporting

Set minimum health signals you review:

• Agents not reporting
• Signatures/engines outdated
• Protection disabled
• High-severity detections and remediation status
• Policy non-compliance / drift Make the reporting cadence explicit and owned (SecOps daily operational review is common; compliance can validate through evidence sampling).

6) Exception handling that does not rot

Central management fails in practice when exclusions become permanent.

• Require ticketed justification for exclusions.
• Set an expiration date and review workflow.
• Track exclusions centrally and report them periodically to the control owner and system owner.

7) Validate with tests, not assumptions

• Spot-check a sample of endpoints and servers to confirm local settings match the central baseline.
• Trigger a benign test event ¹ to confirm alerting and logging.
• Verify new assets enroll automatically or through a documented onboarding step.

8) Package it for assessment readiness

Auditors want a clear story:

• What tool centrally manages malware protection?
• What baseline is enforced?
• How do you know coverage is complete?
• What happens when systems drift or go unhealthy? This is where Daydream fits naturally: use it as the control system of record to map SI-8(1) to the control owner, the implementation procedure, and the recurring evidence artifacts you collect on a schedule.

Required evidence and artifacts to retain

Retain evidence that shows central administration, enforcement, and ongoing operation:

Governance artifacts

• Control narrative for SI-8(1) (scope, tools, roles)
• Anti-malware standard/baseline document (config requirements)
• Exception procedure for exclusions and temporary disables
• RACI or responsibility matrix (SecOps, IT, system owners, third parties)

Technical artifacts (high-value in audits)

• Screenshots or exports from the central console showing:
  • Policy assignments
  • Coverage counts and device inventory views
  • Update/compliance status views
  • Tamper protection settings
• Configuration baseline evidence (exported policy files, settings pages, or IaC equivalents where applicable)
• Sample of detection/incident records showing centralized alerting and response workflow
• Change records for baseline changes (with approvals)
• Exception tickets for exclusions, with approvals and expiration/review outcomes

Third-party artifacts (if managed by an MSP or tool vendor)

• Contract/SOW language that assigns responsibility for policy administration and reporting
• Monthly service reports showing coverage and health
• Access control evidence for who can change central policies

Common exam/audit questions and hangups

Expect these questions and prep answers plus evidence:

1. “Show me that management is centralized.”
   Provide the console access model, policy hierarchy, and proof of enforced baselines.

2. “How do you ensure new assets are enrolled?”
   Show onboarding workflow, automation, and reconciliation between asset inventory and EDR/AV inventory.

3. “Who can create exclusions?”
   Auditors dislike open-ended admin privileges. Show role-based access control, ticketing, and expiry.

4. “How do you know protections aren’t disabled?”
   Show tamper protection, alerts for disabled agents, and response SLAs (if you have them).

5. “What about systems that can’t run the agent?”
   Show documented exception scope and compensating controls. Avoid vague statements.

Frequent implementation mistakes (and how to avoid them)

• Mistake: treating the tool purchase as compliance.
  Fix: document enforced baselines and produce compliance reports that show drift detection.

• Mistake: multiple consoles with no governance.
  Fix: designate authoritative consoles, standardize baselines, and reconcile reporting centrally.

• Mistake: unmanaged exclusions.
  Fix: ticket-based approvals, expirations, periodic review, and reporting of active exclusions.

• Mistake: coverage measured from the wrong source.
  Fix: reconcile against the system asset inventory, not only the security tool’s inventory.

• Mistake: third party manages endpoints but you can’t evidence control.
  Fix: contract for reporting, retain read-only console access if feasible, and store recurring evidence snapshots.

Enforcement context and risk implications

No public enforcement cases were provided in the supplied source catalog for SI-8(1). Treat this as a control that often appears in assessments and authorization decisions rather than a standalone enforcement trigger.

Risk-wise, central management is a control “multiplier.” Weak central governance creates predictable failure modes: inconsistent policies, stale updates, and delayed detection visibility. Those failures increase the chance that malware spreads laterally before containment, and they make incident scoping harder because you can’t rely on uniform telemetry.

Practical 30/60/90-day execution plan

Use this as an operator’s rollout plan. Adjust sequencing to match your change windows and endpoint tooling.

First 30 days (stabilize and define)

• Assign SI-8(1) control owner and approvers.
• Confirm the in-scope system boundary and asset inventory source of truth.
• Select approved central management consoles and document them.
• Draft the anti-malware baseline and exclusion procedure.
• Pull a first coverage report and identify obvious gaps (unmanaged servers, remote endpoints).

Days 31–60 (enforce and evidence)

• Implement baseline policies in the central console(s).
• Turn on tamper protection and central alerting where feasible.
• Implement inventory reconciliation (asset list vs console list) with a defined owner.
• Stand up recurring evidence capture (scheduled exports, dashboard snapshots, or API pulls) and store them in your GRC evidence repository (Daydream can track the evidence cadence and map it back to SI-8(1)).

Days 61–90 (prove operations and close edge cases)

• Run a targeted configuration compliance spot-check and document results.
• Mature exclusion management (expiry, review, reporting).
• Document compensating controls for non-agent assets and get system owner sign-off.
• Prepare an assessor-ready evidence packet: control narrative, baseline, coverage/compliance reports, exception samples, and monitoring workflow proof.

Frequently Asked Questions

Does SI-8(1) require a single anti-malware product across the whole enterprise?

No. It requires central management. You can have more than one tool if you can govern them consistently, document the split, and produce centralized evidence that policies and reporting are controlled.

What counts as “central management” if business units have separate consoles?

Separate consoles can work if you have a single governing standard, controlled admin roles, consistent baselines, and consolidated reporting that lets you attest to coverage and health for the full in-scope boundary.

How do we handle assets that cannot run an endpoint agent?

Document the asset class, why the agent is not feasible, who approved the exception, and what compensating protections apply. Keep the exception list current and review it periodically.

Are anti-malware exclusions automatically noncompliant?

No. Auditors expect some exclusions. The issue is unmanaged exclusions. Require ticketed justification, approval, and an expiration or review trigger, then retain those records as evidence.

What evidence is strongest for SI-8(1) in an audit?

Central console exports showing policy assignments and compliance status, plus proof of monitoring and exception governance. Pair that with a written baseline and a reconciliation method against your asset inventory.

Where does a GRC tool help with SI-8(1)?

It helps you assign ownership, document the procedure, schedule recurring evidence capture, and keep an audit-ready trail of coverage reports and exception approvals. Daydream is a practical fit for that control-to-evidence mapping.
