Example Data Table

Sample rows show how different teams can score differently based on exposure, control coverage, and review freshness.

Team Users Privileged Stale % MFA % Roles Reviewed % Days Since Review Indicative Risk
Finance 220 18 4.0 98.0 85.0 60 Medium
Engineering 480 30 2.5 90.0 70.0 80 Medium
Support 160 4 7.0 75.0 55.0 120 High
IT Operations 95 22 3.0 88.0 60.0 45 High
HR 70 3 1.0 99.0 92.0 30 Low

Formula Used

This calculator computes a weighted risk score from 0 to 100 using normalized control gaps and exposure indicators.

Score = 100 × Σ ( wᵢ × rᵢ )
where 0 ≤ rᵢ ≤ 1 and Σwᵢ = 1
rᵢ values are normalized so higher means worse. Examples: MFA gap uses (100 − MFA%) scaled to a risk band; privileged concentration uses privileged ratio vs. common thresholds.
  • Privileged concentration: privileged_users / total_users mapped to 0–1.
  • Control coverage gaps: MFA, PAM, and roles reviewed reduce risk when higher.
  • Hygiene signals: stale, orphaned accounts, SoD conflicts, exceptions, and review age add risk.

How to Use This Calculator

  1. Collect counts and coverage metrics for the system in scope.
  2. Enter totals, privileged counts, and hygiene indicators.
  3. Fill control coverage percentages for MFA, PAM, and role reviews.
  4. Click Calculate to view results above the form.
  5. Use the suggested review cadence and “accounts to review now” as planning inputs.
  6. Export the latest report to CSV or PDF for evidence packages.

Why periodic user access review matters

User access review reduces dormant privileges and limits insider risk. Many audits expect quarterly evidence for critical systems. Track total users, privileged users, and stale accounts. Use review age to spot overdue certifications. Frequent reviews also catch role drift after reorganizations.

Inputs that drive real exposure

Privileged concentration increases attack impact. Stale accounts raise takeover probability. Orphaned accounts signal ownership gaps. Segregation of duties conflicts increase fraud risk. Exceptions volume shows policy pressure. Critical app count expands the review surface. Compare privileged ratios across departments and vendors.

Control coverage metrics to monitor

MFA coverage lowers credential misuse. PAM coverage reduces admin session abuse. Roles reviewed percentage shows governance completeness. Low coverage should trigger targeted remediation. Raise MFA above 95% for high risk systems. Raise PAM above 80% for administrators. Review break-glass accounts every month.

How the score supports compliance planning

The calculator converts gaps into a 0 to 100 score. Higher scores suggest shorter review cycles. Low risk may fit semiannual reviews. Medium risk often fits quarterly reviews. High risk benefits from monthly sampling. Use the driver list to explain decisions. Keep signoff evidence with dates and approvers.

Operational actions based on results

Review all privileged accounts first. Disable stale accounts beyond policy thresholds. Assign owners for orphaned accounts. Remove SoD conflicts by redesigning roles. Time box exceptions and require compensating controls. Document approvals with tickets for traceability. Add monitoring for sensitive permissions and shared mailboxes.

Reporting and evidence for stakeholders

Export CSV for spreadsheets and dashboards. Export PDF for audit packets and signoff. Share results with system owners and control teams. Trend scores monthly to show improvement. Lower stale percentage by 50% within two cycles. Reduce exceptions by enforcing standard roles. Report completion rates for each critical application. Audit teams prefer trends.

FAQs

What does the risk score represent?

It summarizes access exposure and control gaps into a 0–100 value. Higher scores indicate weaker governance, larger privileged footprints, and older reviews. Use it to prioritize remediation and determine review frequency.

How often should we run an access review?

Run it at least quarterly for critical systems. Use the recommended cadence from the score as a planning baseline. Increase frequency when privileged ratios rise, MFA drops, or exceptions grow.

Which accounts should be reviewed first?

Start with privileged users, break-glass accounts, and service identities. Then review stale accounts, orphaned accounts, and high-impact roles. Confirm owners, business need, and least privilege.

How do MFA and PAM affect the score?

Higher MFA coverage reduces credential abuse risk. Higher PAM coverage reduces privileged session misuse. Low coverage increases normalized risk components and raises the overall score.

Can we use this for multiple systems?

Yes. Run separate calculations per system or application. Keep inputs scoped to that system’s identities and controls. Store exports as evidence for each owner and audit period.

What should we attach as evidence?

Attach exports plus access lists, approvals, and change tickets. Include review date, reviewer, and decisions. Note exceptions with expiry and compensating controls. Keep artifacts in a controlled repository.
