Port scanning is the first step in most attacks, allowing adversaries to identify running services and potential vulnerabilities.
What is Port Scanning?
Port scanning probes a server's network ports to identify which services are running and potentially vulnerable.
Scanning Techniques
- TCP Connect Scan - Full TCP handshake to identify open ports.
- SYN Scan - Half-open scanning for faster, stealthier results.
- UDP Scan - Probing UDP services, slower but important.
Detection Methods
- Intrusion Detection - IDS systems can identify scanning patterns.
- Log Analysis - Monitor for unusual connection patterns.
- Honeypots - Decoy systems that attract and detect scanners.
Conclusion
Port scanning is often the first indicator of an impending attack. By detecting scans early and blocking known scanner IPs with Fraudcache feeds, you can stop reconnaissance before it leads to compromise.
