RECOMMENDED ACTIONS

SOC Analyst Guidance:

1. ALLOW with Monitoring: Permissive rules acceptable given cloud infrastructure classification. Monitor for anomalous outbound connections.

2. DNSBL Review: Investigate the 2 DNSBL listings to determine if they relate to legitimate cloud service traffic or potential abuse.

3. Route Stability Alert: Flag routing instability for BGP monitoring. Investigate if prefix announcements correlate with observed activity.

4. Baseline Established: No immediate blocking recommended. Establish behavioral baselines for Azure traffic patterns.

5. Future Watch: Monitor for escalation in DNSBL listings or emergence of threat indicators.
