Nmap is a command line network detection tool that supports ping scanning to identify network hosts, port scanning technology, and TCP/IP fingerprints. Nmap can determine which services are running on which terminals and infer which operating system the computer is running (also known as fingerprinting ). It is one of the necessary software for network administrators and is used to evaluate the security of network systems. Like most tools used for network security, nmap is also a popular tool for many hackers and hackers (also known as script boys. System
Nmap is a command line network detection tool that supports ping scanning to identify network hosts, port scanning technology, and TCP/IP fingerprints.
Nmap can determine which services are running on which terminals and infer which operating system the computer is running (also known as fingerprinting ). It is one of the necessary software for network administrators and is used to evaluate the security of network systems.
Like most tools used for network security, nmap is also a popular tool for many hackers and hackers (also known as script boys. System Administrators can use nmap to detect unapproved servers in the work environment, but hackers will use nmap to collect network settings of the target computer and plan the attack methods.
Nmap is often confused with the system vulnerability assessment software Nessus. Nmap uses a secret technique to avoid intrusion into the monitoring system, and does not affect the daily operations of the target system as much as possible.
In The Matrix, Nmap, together with The SSH1 32-bit Cyclic Redundancy Verification Vulnerability, was intruded into The energy management system of The power station by Cui NIDI.
