Port Scanner
(Please ensure you have explicit permission before scanning any network.)
Note: This tool is for educational purposes only. Scanning ports on systems without permission may violate laws and regulations. Always have explicit authorization before performing any scans.
What is Port Scanning?
Port scanning is a technique used to identify open ports and services available on a networked device. It is often used by network administrators for security assessments and by attackers to find vulnerabilities.
How it Works
- Port scanning sends requests to various ports on a target device to determine their status
- Open ports indicate services that are running and potentially vulnerable
- Scans can be performed using various methods, including TCP and UDP scans
- Common tools for port scanning include Nmap and Netcat
Security Principles
- Network Visibility: Port scanning helps identify exposed services that may be exploited
- Vulnerability Assessment: Regular scans can help in identifying and mitigating security risks
- Intrusion Detection: Unusual scanning activity can indicate potential attacks
- Ethical Considerations: Scanning should only be performed on networks you own or have permission to test
