Primary Use Case: Account Security & Risk Alerts

Background Overview

Account security is critical for protecting customer data and preventing data breaches. Without monitoring and alerts, security incidents may go undetected causing significant damage. This primary use case describes account monitoring, risk detection, and incident response to maintain security posture.

Goals & Value

• Behavior Monitoring: Track account activities for anomalies.
• Risk Alerts: Early warning of potential security threats.
• Incident Response: Rapid response to security incidents.
• Prevention Measures: Proactive security controls and education.

Participating Roles

• Security Team: Monitor security alerts and handle incidents.
• IT Operations: Implement security controls and patches.
• Management: Review security metrics and approve responses.
• Customer Service: Assist customers with security issues.
• External Partners: Collaborate on security investigations.

Primary Scenario User Story

As a security analyst, I want to monitor account behaviors and receive automated alerts for anomalies, so that I can prevent security incidents and protect customer data.

Sub-scenario Details

Sub-scenario A: Account Activity Monitoring

• Roles & Triggers: Need to monitor account activities continuously.
• Main Process:
  1. Track login locations, devices, and times.
  2. Monitor data access and export activities.
  3. Track permission changes and configuration updates.
  4. Analyze behavior patterns for anomalies.
• Success Criteria: Complete visibility; accurate anomaly detection; real-time monitoring.
• Exceptions & Risk Control: Handle false positives; protect privacy; maintain monitoring logs.
• Metric Suggestions: Monitoring coverage, anomaly accuracy, alert volume.

Sub-scenario B: Risk Detection & Alerting

• Roles & Triggers: Detect potential security risks.
• Main Process:
  1. Identify suspicious login patterns (multiple locations, unusual times).
  2. Detect account sharing and credential abuse.
  3. Monitor data export volumes and frequencies.
  4. Send alerts to security team and account owners.
• Success Criteria: Early detection; accurate alerts; actionable intelligence.
• Exceptions & Risk Control: Reduce false positives; verify before action; document alerts.
• Metric Suggestions: Detection accuracy, false positive rate, response time.

Sub-scenario C: Incident Response & Remediation

• Roles & Triggers: Security incidents require immediate action.
• Main Process:
  1. Automatically lock compromised accounts.
  2. Notify account owners and security team.
  3. Investigate incident scope and impact.
  4. Remediate and restore normal operations.
• Success Criteria: Rapid response; contained incidents; complete remediation.
• Exceptions & Risk Control: Verify incidents before action; minimize disruption; document actions.
• Metric Suggestions: Response time, incident containment, remediation success.

Sub-scenario D: Security Education & Prevention

• Roles & Triggers: Prevent future security incidents.
• Main Process:
  1. Educate users on security best practices.
  2. Implement multi-factor authentication.
  3. Regular security assessments and updates.
  4. Share threat intelligence and prevention tips.
• Success Criteria: Increased security awareness; reduced incidents; proactive protection.
• Exceptions & Risk Control: Respect user privacy; communicate clearly; measure effectiveness.
• Metric Suggestions: Security training completion, incident reduction, user satisfaction.

Scenario-level Test Case Examples

Test Preparation: Prepare security monitoring tools, alert systems, incident response workflows, and user education materials.

Test Case A-1: Suspicious Login Detection (Positive)

• Prerequisites: User account has normal login patterns.
• Steps:
  1. Simulate login from unusual location.
  2. Monitor system response.
• Expected Results:
  • System flags unusual login activity.
  • Alert sent to user and security team.
  • Account may be temporarily locked for verification.

Test Case B-1: Data Export Monitoring (Negative)

• Prerequisites: User has access to customer data.
• Steps:
  1. Simulate large data export activity.
  2. Monitor alert response.
• Expected Results:
  • System detects unusual export volume.
  • Alert sent to security team.
  • Investigation initiated to verify legitimacy.
