Nmap Scanning

A network scanning tool used to discover hosts, services, and vulnerabilities.

Understanding:

Nmap (Network Mapper) is an open-source tool used for network discovery and security auditing. It helps identify live hosts, open ports, running services, and potential vulnerabilities in a network.

Common Applications and Use Cases:

Used by penetration testers to map network infrastructure and detect misconfigurations.
Employed by system administrators to monitor network health and troubleshoot connectivity issues.
Helps security teams identify unauthorized services and potential attack vectors.

Best Practices and Security Considerations:

Use Nmap with proper authorization to avoid legal and compliance issues.
Limit scan aggressiveness to prevent network disruptions.
Regularly update Nmap scripts (NSE) to detect the latest threats.
