What problem does it solve?
This Skill detects subtle, gradual expansions of access or behavior in Entra ID service principals that can evade traditional alerts, helping to identify potential misuse or credential compromise before it escalates.
Core Features & Use Cases
- Behavioral Baseline: Establishes a 90-day baseline of SPN activity (sign-ins, resources accessed, locations, etc.).
- Drift Scoring: Compares recent activity to the baseline across multiple dimensions, calculating a weighted Drift Score.
- Corroboration: Correlates drift signals with Audit Logs (permission changes) and Security Alerts for comprehensive investigation.
- Use Case: An automation account used for backups suddenly starts accessing financial reporting APIs. This skill would flag the SPN due to a significant increase in accessed resources and potentially new IP addresses, prompting an investigation.
Quick Start
Use the scope-drift-detection-spn skill to investigate potential scope drift for the service principal named 'backup-automation-spn'.
