Server Port Security Scanner & Open Service Auditing
Audit open server ports to secure web infrastructure against unauthorized network access.
Technical Overview & Core Purpose
Port scanning tests specific network ports (e.g. SSH 22, HTTP 80, HTTPS 443, MySQL 3306) on a host to identify active network services. Closing unnecessary open ports reduces server attack surfaces and prevents malicious intrusions.
Key Benefits & Use Cases
- Detect unintended open ports (e.g. database or FTP ports exposed to public IP).
- Verify firewall rules after web server hardening.
- Ensure HTTPS (Port 443) and HTTP (Port 80) respond correctly.
Frequently Asked Questions (FAQ)
Q: Which ports should be publicly open on a web server?A: Only Port 80 (HTTP) and Port 443 (HTTPS) should be open publicly; SSH (22) should be restricted via firewall.
