Port Scanning
Port scanning is the process of scanning a computer network looking for open ports. A port is a communication endpoint on a computer or network device. Computers and network devices have many ports, some of which are intended for specific types of traffic, such as HTTP (port 80) or SMTP (port 25). Port scanning is usually done by hackers or security professionals to identify potential vulnerabilities that can be exploited, or to identify services and applications that are running on the network.
Hackers use port scanning as a tool to identify computers that are vulnerable to attack. If a computer has an open port that is associated with a known vulnerability, the hacker may be able to gain unauthorized access to the computer. Security professionals also use port scanning as a tool to identify open ports and to test the security of a network.
Port scanning can be done using a variety of tools, including Nmap, Angry IP Scanner, or Fing. These tools allow users to scan for open ports on a single computer, or on an entire network. Port scanning can be a time-consuming process, especially if a large number of computers or devices are being scanned.
In conclusion, port scanning is the process of scanning a computer network looking for open ports. It can be used by hackers to find vulnerabilities, or by security professionals to test the security of a network.
