Namp’s features and usage
Nmap is an open-source network scanning and security assessment tool that can be used to identify hosts, ports, and services on a network, as well as provide detailed information about them. Here are some key features and uses of Nmap:
- On the internet, it was found that Nmap can scan specified ranges of IP addresses to discover active hosts on a network. It can detect whether hosts are online and identify the type of operating system they are using.
- Port scanning: Nmap can scan the open ports on a host and determine the type of service they are running. It can utilize various scanning techniques such as TCP SYN scan, TCP connect scan, and UDP scan.
- Service and version detection: Nmap can determine the specific services running on a host and their version information by sending specific network requests. This is very useful for identifying potential security vulnerabilities and weaknesses on the host.
- Operating System Detection: Nmap can determine the type of operating system on a host by analyzing its network responses and characteristics, making it useful for identifying untrusted hosts on a network or conducting security assessments.
- Script scanning: Nmap allows the use of custom scripts to scan hosts and services. These scripts can perform various tasks such as vulnerability detection, weak password guessing, and service discovery.
- Output formats: Nmap can output scan results in various formats, such as text, XML, and HTML, making analysis and reporting of results more convenient and readable.
Users can operate Nmap either through the command line interface (CLI) or the graphical user interface (GUI). They can specify the target IP addresses, port ranges, and scanning techniques they want to use. Nmap also provides many options and parameters for users to customize their configurations according to their needs.
