Segregation of Duties Violation Count

Goal of the analysis:

The goal is to quantify and understand instances where users possess conflicting access rights or perform incompatible activities that could enable fraud, error, or policy breaches. For executives, the Segregation of Duties (SoD) Violation Count is a leading indicator of control effectiveness across financial, operational, and compliance processes. It helps prioritize remediation, reduce audit findings, and lower risk of material misstatement or operational loss. The analysis translates complex access landscapes into actionable insights, highlights systemic issues (e.g., role design flaws), and informs governance and investment decisions across identity, ERP, and process controls.

Data required:

• Access and identity data:
  • User master data: user IDs, employee IDs, department, location, employment status.
  • User-role and role-entitlement mappings from ERP/IAM (e.g., SAP, Oracle, Workday, SailPoint, Azure AD).
  • Entitlement catalog: permissions, transactions, or T-codes mapped to business activities.
  • Joiner-mover-leaver (JML) events and effective dates.
• SoD ruleset and risk taxonomy:
  • Defined SoD conflict rules (e.g., “Create Vendor” AND “Process Payment”).
  • Risk ratings per rule (High/Medium/Low), control objectives, process ownership.
  • Mitigating controls inventory (e.g., post-payment review, dual authorization) and effectiveness status.
• Activity and transaction data (for detective SoD):
  • Transaction logs linking users to executed activities (e.g., created POs, approved invoices, posted journals).
  • Event timestamps to determine if the same user performed both sides of a conflict in a period.
  • Exception logs and case management tickets related to SoD or fraud reviews.
• Governance and reference data:
  • Policy thresholds (e.g., “no unmitigated High-risk violations allowed”).
  • Org hierarchy (business units, functions, geographies) for segmentation.
  • Historical snapshots of access and violations for trending.
• Remediation and audit data:
  • Open and closed remediation items, target dates, and owners.
  • External/internal audit findings related to SoD and access controls.

Detailed step-by-step instruction on how to conduct the analysis:

1. Define scope and period. Select in-scope systems (e.g., SAP S/4HANA FI/CO, Oracle EBS, Coupa) and time window (e.g., quarter). Confirm which processes are covered (P2P, O2C, R2R, ITGC).
2. Confirm the SoD ruleset. Validate the conflict library and risk ratings with control owners. Remove obsolete rules and add process-specific conflicts. Document mitigating controls and evidence requirements.
3. Extract access and activity data. From ERP/IAM tools (SAP GRC, Oracle AAC, SailPoint, ServiceNow), export user-role-privilege mappings. From transaction logs, export user activity records. Ensure consistent user identifiers across datasets.
4. Normalize and cleanse. Standardize role and entitlement naming, de-duplicate users, map contractors and service accounts, and align org units. Remove terminated users effective prior to the period, but tag lingering access as exceptions.
5. Run access-based SoD analysis. Using the SoD engine or SQL/BI logic, test each user’s entitlements against the ruleset to identify conflicts. For each violation, capture user, conflict rule, risk rating, system, role sources, and date detected.
6. Run activity-based (detective) SoD analysis. Identify cases where the same user executed both sides of a conflicting activity within the period (e.g., created and approved the same vendor/payment). Link to document IDs to avoid false positives.
7. Apply mitigating controls. For each violation, check if an approved, effective mitigating control exists and was operating during the period. Reclassify violations as mitigated or unmitigated, and adjust residual risk.
8. De-duplicate and rationalize counts.
   • Within-user duplicates: count one violation per unique rule per system per user.
   • Roll-up logic: show both gross (all hits) and net (unique unmitigated) counts.
   • Key metrics: Violations per 100 users; % users with ≥1 High-risk unmitigated violation.
9. Segment and attribute. Break down by business unit, geography, process, system, role, and manager. Identify concentration (e.g., 60% of High-risk violations within two roles).
10. Trend and benchmark. Compare current counts and rates to prior periods, targets, and peers/business units. Plot time to remediate and aging buckets (0–30, 31–60, 61–90, 90+ days).
11. Validate and investigate outliers. Sample test a subset of High-risk violations to confirm accuracy. Investigate spikes (e.g., role redesign, acquisition onboarding) and confirm false positives vs. genuine exposure.
12. Prioritize remediation. Rank by risk and business criticality. Assign owners, due dates, and remediation paths (revoke access, redesign role, add mitigation, or process change). Capture effort and impact.
13. Document and socialize. Prepare executive-ready outputs: a one-page summary, detailed appendices by segment, and a remediation tracker. Align with Audit, IT, and business control owners.

Format of the output of analysis:

• Executive summary slide with total violations, % unmitigated high-risk, and top three root causes.
• Dashboard with:
  • Trend lines of total vs. unmitigated violations and % users impacted.
  • Heat map by process and business unit (risk-weighted counts).
  • Top violating roles/entitlements and their contribution to total.
  • Aging of open violations and time-to-remediate distributions.
• Detailed tables:
  • User-level violation list with rule, risk rating, mitigation status, and remediation owner.
  • Role-level mapping showing entitlements causing conflicts and proposed changes.
• Benchmark view: internal targets vs. current, peer business unit comparison.
• Remediation tracker with counts closed/created this period and SLA adherence.

How to interpret results:

• High total count with high unmitigated proportion: Indicates structural control weaknesses (poor role design, weak provisioning). Immediate risk exposure—prioritize High-risk conflicts.
• High count but largely mitigated: Residual risk lower, but monitor mitigation effectiveness and burden; may signal over-reliance on detective controls.
• Low count: Positive, but validate ruleset coverage and false negatives. Ensure critical processes and systems are in scope.
• Concentration in few roles or units: Suggests targeted redesign or training can yield outsized impact. Persistent hotspots indicate governance gaps.
• Worsening trend or long aging: Deterioration in control discipline or resourcing. SLA misses increase audit and regulatory scrutiny.
• Differences across processes: P2P often carries more High-risk conflicts (vendor and payment); O2C conflicts may center on credit and collections; R2R on journal entry creation/approval.
• Benchmark comparisons: Use targets to contextualize performance. Falling short on % users with unmitigated High-risk violations or remediation SLAs indicates priority action.

Steps a company can take to improve on this measure:

• Process and policy enhancements:
  • Strengthen JML processes; enforce timely de-provisioning on terminations and role changes.
  • Mandate periodic access recertifications with clear accountability for approvers.
  • Define risk-based SLAs (e.g., High-risk remediated within 30 days) and track adherence.
  • Implement an emergency access (firefighter) process with time-bound approvals and post-use review.
• Data, systems, and tooling:
  • Deploy or tune GRC/IAM SoD engines; maintain an up-to-date ruleset aligned to current processes.
  • Integrate HRIS feeds to automate JML triggers; enable real-time revocation on status changes.
  • Refactor coarse roles into least-privilege role designs; apply attribute-based access where feasible.
  • Automate mitigating controls evidence collection and effectiveness testing.
• Capability, training, and governance:
  • Establish role owners and control owners with defined KPIs (violation rate, SLA adherence).
  • Train approvers on SoD risk and how to evaluate access requests.
  • Create a cross-functional SoD council (IT, Finance, Operations, Audit) to manage rule updates and exceptions.
• Targeted remediation and redesign:
  • If High-risk count is high but concentrated in few roles, prioritize role redesign and entitlement pruning.
  • If activity-based conflicts persist, introduce workflow segregation (dual approvals, dollar thresholds) and strengthen detective analytics.
  • If many violations are “mitigated,” reassess whether to replace detective controls with preventive design to reduce residual risk and cost.

Benchmark comparisons:

General benchmarks:

• % of users with unmitigated High-risk SoD violations: Target < 1–2%; top performers often sustain < 1% with quarterly certification.
• Time to remediate High-risk violations: 80–90% closed within 30 days; Medium within 60 days.
• Violations per 100 users (net, unmitigated): Varies with system complexity; target trending down quarter-over-quarter.

Segment- or industry-specific benchmarks:

• Highly regulated industries (financial services, healthcare): Stricter thresholds (often zero tolerance for unmitigated High-risk) and monthly certifications.
• Complex multi-ERP environments: Higher baseline counts initially; best-in-class programs achieve rapid reduction post role harmonization.
• Shared services/BPO models: Concentration risk; top quartile maintain near-zero unmitigated High-risk by using standardized roles and central governance.

Constructing internal benchmarks where externals are limited:

• Track rolling 12-month trends for each business unit and system; set targets based on top quartile internal performers.
• Normalize by user population and process complexity (e.g., violations per 1,000 entitlements) to compare across units.
• Use pre- and post-initiative baselines (e.g., after role redesign) to quantify improvement and reset targets.
