What is nmap tool?

Nmap is a tool in Kali Linux used to target systems using IP addresses.

It is an open-source and free to use tool, for scanning things connected to the internet or a network.  

Nmap was designed by Gordon Lyon (Fyodor) in 1997. 

It helps to find devices on a network, like computers, servers, or printers. It can also check what services are running on those devices, like websites or email servers.

Nmap is mostly used to understand networks and find security problems. It’s a very powerful tool for hackers, cybersecurity experts, and network admins.

What we do with Nmap tool?

• Scanning networks
• Host discovery
• Check active ports
• Check services running on devices
• Detect operating systems
• Find security vulnerabilities
• Map network devices and connections
• Run scripts on IP addresses
• Monitor network uptime and availability
• Aggressive Scanning

What are the Maximum Capabilities of Nmap?

Find Devices: Discovers all devices connected to a network.

Check Ports: Identifies which ports are open or closed on a device.

Guess OS: Detects the operating system of a target device.

Find Services: Lists running services (like web servers or databases) and their versions.

Spot Weaknesses: Scans for security vulnerabilities in systems.

Bypass Firewalls: Uses tricks to avoid detection by firewalls or security systems.

Stealth Mode: Scans quietly to avoid being noticed.

Map Networks: Creates a visual map of all connected devices.

Test Logins: Tries to crack weak passwords or logins.

Detect Malware: Finds infected systems or hidden backdoors.
