## SOC ACTIONABLE INTELLIGENCE

Risk Assessment

This IP does not meet criteria for immediate blocking but warrants contextual monitoring due to subnet abuse density. The moderate risk score (55) with no active threat indicators suggests benign but potentially misconfigured infrastructure.

Monitoring Recommendations

1. Passive Monitoring: Monitor for outbound connections to known malicious destinations

2. Subnet Context: Be aware of 2 other IPs in the /24 subnet with elevated risk

3. DNSBL Watch: 3 DNSBL listings may indicate prior reputation issues

4. SSH Exposure: Port 22/SSH is open – verify if this is expected for CariNet infrastructure

Firewall/Rule Considerations

• No immediate blocking required
• Consider geo-blocking if traffic originates from non-US destinations
• Monitor for port scanning activity against port 22
• Review DNSBL listings if receiving complaints

Threat Indicators

Current: None

Historical: 1 threat observation recorded

Campaign Correlation: No matches in known campaigns

## CONCLUSION

IP 71.6.199.23 is a CariNet infrastructure endpoint with moderate risk characteristics. The primary concern is the high abuse density within its /24 subnet (66.67%), suggesting this IP may share infrastructure with other entities. While the IP itself shows no active malicious behavior, the subnet context warrants continued monitoring for correlated activity.

Recommended Action: Monitor with contextual awareness; no immediate remediation required.
