Port Scan 234 Layer discovery is only to accurately discover all live host IP, identify attack surface, port scan to discover attack point, Discover open port. The port corresponds to the Network service and application program, a

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

Nmap is not limited to collecting information and enumerations, but can also be used as a vulnerability detector or security scanner. It can be applied to operating systems such as Winodws,linux,macNmap is a very powerful utility that can be used to: Detect hosts on the network (host discovery) detect open

First, TCP Commonly used port scanning methods are the following three: 1.connect scanning We know that the common TCP socket implementation process is The more essential connection and end process is the following: From the above two figures we can see that the target host of a port if the monitoring state (listening or linsten), then when I connect the target host can be successful, otherwise the

I have been working for half a year on part-time security. I would like to share with you how I am doing security here. of course, as a part-time employee, I am not very thorough and I am not a reference for attacking. The following describes port security, which is mainly used to enable ports for all ip segments in the IDC of the company. for example, for a server, only the ssh port is required by default.
