RECOMMENDED ACTIONS

For Inbound Traffic:

• Default: Allow or monitor based on organizational policy for search bots
• Firewall Rule: No blocking required; this is Microsoft infrastructure
• Rate Limiting: Apply standard search bot rate limiting if applicable

For Outbound Traffic:

• No Action Required: This is an outbound search bot IP from Microsoft

Contextual Intelligence:

• Monitor subnet 52.167.144.0/24 for related malicious activity
• Be aware that 45 sibling IPs in this subnet have threat indicators
• Correlate any suspicious activity from this /24 subnet with Microsoft infrastructure attribution

SOC Analyst Note: This IP should not be blocked as malicious activity. The elevated risk profile is environment-driven (high-abuse subnet) rather than IP-specific. Maintain allow rules with standard logging for compliance purposes.
