Problems solved by technology

[0002] At present, during port detection, the port scanning methods are generally TCP (Transmission Control Protocol, Transmission Control Protocol) full connection scanning and SYN (Synchronize Sequence Numbers, synchronization sequence number) semi-connection scanning such as figure 1 and figure 2 As shown, but the defect is that both TCP and SYN have handshake responses. When a user initiates a large number of TCP full connection or SYN half connection requests, the detected target machine is likely to record these connections. The firewall or IDS (intrusion detection system, intrusion detection system) will also capture two scanning methods; in this way, scanning the same machine or a large number of adjacent IP machines at the same time is easy to be filtered by the firewall on the target machine or block the IP, making it impossible to carry out the port normally. detection

Abstract

The embodiment of the invention provides a port detection method and device based on Raw Socket. The method comprises the following steps: constructing a port detection packet through Raw Socket; sending the port detection packet to a test target machine; if the RST message returned by the test target machine is received, confirming that the port of the test target machine is closed; and otherwise, confirming that the port of the test target machine is opened. In this way, the Raw Socket message can be utilized to bypass port detection of the stateless firewall / IDS system so as to prevent the scanning machine from being blocked as much as possible.

technical field [0001] The present disclosure relates to the field of testing, in particular to the technical field of port detection. Background technique [0002] At present, during port detection, the port scanning methods are generally TCP (Transmission Control Protocol, Transmission Control Protocol) full connection scanning and SYN (Synchronize Sequence Numbers, synchronization sequence number) semi-connection scanning such as figure 1 and figure 2 As shown, but the defect is that both TCP and SYN have handshake responses.

The firewall or IDS (intrusion detection system, intrusion detection system) will also capture two scanning methods; in this way, scanning the same machine or a large number of adjacent IP machines at the same time is easy to be filtered by the firewall on the target machine or block the IP,...
