On the network and scans them for open ports. NMAP scans more than just computers too. It scans any device connected to the network including desktops, mobile devices, routers, and IoT devices.NMAP is an open-source tool available for free at the developer website. It runs on Linux, Mac, and Windows operating systems. The utility has been a part of most network administrator and ethical hacking tools for years, and it’s useful for finding devices on a network and determining if they have vulnerable services running on them.How to Do an NMAP UDP ScanBefore performing an NMAP scan, open the NMAP GUI or open your command-line utility. Most administrators use NMAP in the command line, because it’s quick and easy to use with basic output for review. After typing the command, the NMAP tool searches for devices on a subnet. Every subnet has a definitive number of hosts, so NMAP scans every possibility for a host response. With a host response, the NMAP tool then identifies open UDP and TCP ports.You can scan specific ports on NMAP too instead of scanning all IP addresses for all open ports. Ports are given a numerical value between 1 and 65,535, so you should perform a lookup of services running on a specific port before running a scan. Once you choose a port, you can execute the following command:nmap -p 22 192.168.1.100The above NMAP scan searches for the open port 22 (the SSH service) running on a device with the IP address 192.168.1.100. If the service is running on the target host, the NMAP output displays the state as open. If not, the NMAP output displays the state as closed.UDP scans are slower than TCP scans, so you might experience extreme lag in responses or long delays before the tool displays output. Some hosts might take up to an hour to scan if you don’t optimize the NMAP process. You can speed up UDP scans depending on the use case. For example, use the following NMAP command to eliminate slow-responding hosts and gives up on scans when a host does not respond within 1 minute:nmap 192.168.1.100 --host-timeout 1mWithout specifying TCP or UDP, NMAP will try all open ports. Another way to optimize scans is to limit them to UDP ports and set the version intensity. Setting the version intensity to 0 will only show common services running on the target host. Version intensity ranges

Ethical hacking covers a diverse range of techniques used to discover vulnerabilities in an organization's cyberdefenses in order to help protect them against cyber attacks. As attacks come in many shapes and sizes, ethical hackers should make sure they mirror techniques used by criminals. Thankfully, various tools are available to emulate and automate some of the hacking process. The following are five ethical hacking tools every hacker should know how to use. 1. Nmap To hack a company, an ethical hacker needs to discover its weak spots and possible points of entry. Nmap is a free tool that scans an organization's infrastructure for open ports. If open ports are found, ethical hackers can then run scripts against them to determine vulnerabilities and whether the vulnerabilities provide an entry point into the organization's network. Be aware that Nmap is just a starting point; ethical hackers need to have skills and knowledge to use the information Nmap scans return. 2. Gobuster Gobuster is like Nmap for websites. Many websites have hidden links, for example, to extra login pages or administrative areas of the site. Gobuster scans for hidden areas not indexed by Google or discoverable through normal website interaction. These can provide alternative avenues to explore and lead to administrative interfaces that can be brute-forced or logged in to with credentials stolen from data breaches. 3. Burp Suite Professional An essential component of any ethical hacker tool set, Burp Suite Professional is hands down the best tool for assessing a website's security.
