## RECOMMENDED ACTIONS

For SOC Analysts:

1. Allow Traffic: No blocking required. IP is legitimate Microsoft Azure infrastructure

2. Monitor Context: Review traffic patterns to understand purpose (likely cloud service communication)

3. No Firewall Rules: Standard allow rules appropriate for Microsoft cloud IPs

4. Threat Hunting: No immediate investigation needed unless correlated with other suspicious activity

Firewall Recommendations:

• No specific iptables/nftables rules recommended
• Standard Microsoft Azure IP allowlist may include this range
• Monitor for unusual connection patterns if this IP appears unexpectedly in traffic
