# Executive Brief: Security Operations Assessment

**Engagement type:** Independent portfolio simulation  
**Organization:** Fictional 250-person professional-services company  
**Data period:** Synthetic 30-day authentication dataset  
**Status:** Demonstration only; not a real client assessment

## Executive summary

A review of 600 fabricated authentication events identified several patterns worth investigating in a real environment: repeated authentication failures across multiple accounts, successful sign-ins tagged as unusual-location scenarios, legacy-style authentication without an MFA challenge, and privileged sign-ins without an MFA challenge. These are simulated patterns built into the dataset, not evidence of a real compromise. The exercise demonstrates a repeatable triage method and a practical sequence for improving identity controls and alert handling.

## Scope and method

The dataset contains 600 events and 63 distinct user identifiers. The analysis uses transparent rules: repeated failures from one source across at least five accounts; successful sign-ins in the synthetic unusual-location scenario; legacy-style events without an MFA challenge; and successful privileged-account events without an MFA challenge. Rules are intentionally simple and should be tuned against an organization's baseline before production use.

## Priority findings

1. **Privileged access without an MFA challenge — Critical.** Ten scenario events were created to test this control gap. In a real engagement, validate identity-provider records, account privilege, conditional-access policy, and session context before concluding that access was unauthorized.
2. **Repeated failures across multiple accounts — High.** A synthetic burst of 60 failed attempts across eight accounts is intended to test password-spray triage. Validate source reputation and account activity; then review lockout, MFA, and alerting controls.
3. **Legacy-style authentication without an MFA challenge — High.** Fifteen synthetic events test whether older authentication paths remain enabled. Confirm application dependencies before disabling protocols.
4. **Unusual-location sign-ins — Medium pending validation.** Fifteen synthetic successful events test contextual triage. Location alone is not proof of malicious activity; compare VPN, device, travel, and sign-in history.

## Recommended 30/60/90-day plan

- **Days 0–30:** Require MFA for privileged accounts; review privileged sessions and identity-policy exceptions; validate lockout controls; assign owners to high-priority findings.
- **Days 31–60:** Inventory and restrict legacy authentication; create a repeatable sign-in triage playbook; correlate alerts with device and VPN context.
- **Days 61–90:** Expand managed-device requirements for sensitive applications; test incident escalation and account-containment procedures; report control coverage and unresolved exceptions to leadership.

## Success measures

- All privileged accounts covered by MFA, with exceptions documented and time-bound.
- Repeated-failure alerts tested against representative benign and suspicious activity.
- Legacy authentication disabled or formally exception-approved.
- Triage playbook includes evidence capture, escalation, containment authority, and false-positive handling.
- Monthly reporting tracks alert volume, validation rate, time to triage, and overdue remediation.

## Limitations and assumptions

This is a synthetic dataset with scenario tags used to make the exercise reproducible. The results do not estimate real-world attack prevalence, prove compromise, or validate a production detection system. Cost estimates are intentionally omitted because no organization-specific environment, licensing, staffing, or vendor quotes were available. A real consulting engagement would confirm the asset inventory, identity architecture, business requirements, control ownership, and baseline behavior before finalizing recommendations.
