Recommendations
- Block IP 46.21.82.34 at network perimeter and monitor for similar scanning patterns from German IP ranges
- Review web application firewall rules to ensure coverage against common vulnerability scanning techniques
- Conduct vulnerability assessments on externally-facing web applications, particularly those on the targeted ports
- Implement rate limiting on web servers to mitigate automated scanning attempts
- Monitor logs for successful exploitation attempts following reconnaissance activity patterns
