Port Scan path:What is a scanner?A scanner automatically detects remote or local host security vulnerabilities.ProgramBy using a scanner, you can discover the distribution of various TCP ports on the remote server and the services provided and their software versions! This allows us to indirectly or intuitively understand the security problems of remote hosts.
Working PrincipleThe scanner collects a lot o
