Port scanning topic

Port scanning refers to someone with ulterior motives sending a set of port scanning messages in an attempt to invade a computer and learn the type of computer network services it provides (these network services are all related to port numbers). Port scanning is a method favored by computer decryption experts. It allows attackers to learn where to exploit weaknesses. Essentially, port scanning involves sending messages to each port, one message at a time. The type of response received indicates whether the port is in use and can be used to detect vulnerabilities. A scanner is a program that automatically detects security vulnerabilities of remote or local hosts. By using the scanner, you can discover the allocation of various TCP ports of the remote server and the services provided and their software versions without leaving any trace! This allows us to indirectly or intuitively understand the security problems of the remote host.
