## Executive Summary Identified 1 potentially suspicious AssumeRole event from an external IP address during business hours. Risk level: Medium - requires investigation of source IP and user context. ## Detailed Analysis **Event Timeline:** - 2024-01-15 14:30:00 UTC: AssumeRole operation by admin-user from IP 203.0.113.12 **Anomaly Detection:** - External IP address (203.0.113.12) not in typical corporate ranges - AWS CLI usage suggests programmatic access - Admin-level role assumption requires validation ## Security Assessment **Risk Factors:** - Privileged role access from unrecognized source - Potential for lateral movement if compromised - No MFA indication in log entry ## Recommendations **Immediate Actions:** 1. Verify IP 203.0.113.12 against approved access locations 2. Contact admin-user to confirm legitimate activity 3. Review subsequent API calls made after role assumption **Long-term Improvements:** 1. Implement IP allowlisting for admin roles 2. Enforce MFA for all AssumeRole operations 3. Set up CloudWatch alerts for external IP role assumptions
