Recommendations
- Block source IP 208.95.112.1 at perimeter firewalls and intrusion prevention systems
- Review firewall logs for any successful connections from this IP address during the attack window
- Implement rate-limiting rules for TCP connection attempts from single source IPs
- Monitor for similar scanning patterns from related IP ranges or ASNs
- Validate that scanned services are properly hardened and non-essential ports are filtered
