Nmap performs several phases in order to achieve its purpose: Nmap is a very effective port scanner, known as the de-facto tool for finding open ports and services. Service detection (-sV) is also enabled in this port scanningĬonfiguration and you will get the version of the running services. The Light Scan checks only for the most common Top 100 TCP ports. Enable/disable operating system detectionįurthermore, you can schedule periodic port scans to continuously monitor the attack surface of your network perimeter.Specify custom TCP ports to scan (1-65535).The Full Scan allows you to perform portscans with custom parameters, easily configured from the web interface: Gives you a useful report that you can share with management or stakeholdersĪccording to the Nmap classification, these are the most common TCP ports:.Has an easy-to-use interface over the complex command line parameters of Nmap.If you do the same scan from your internal network you may obtain different resultsīecause of various firewalls and network restrictions. Your systems as any malicious hacker from the Internet has.

Scan techniques are different for TCP and UDP ports, which is Port scanning is part of the first phase of a penetration test and allows you to find all network entry points available on a target system.

scripts, bots, malware) often exploit code found in server software that lets them get unauthorized access on When a service listens on a port it can receive dataįrom a client application, process it and communicate a response.
