In the network scanning method of system information collection, there is always a trade-off between the scanning rate and the amount of information collected, that is, under the same hardware resources and network environment, the faster the scanning rate, the less system information collected , the more abundant system information you want to collect, the faster the scan rate will be greatly reduced

Embodiment Construction
[0024] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings.
[0025] The invention proposes a stateless TCP network scanning method, which constructs a complete TCP session through IP data packet load TCP data, establishes a normal TCP connection, sends normal TCP protocol request data, and ignores the TCP connection state. Within the limited time, check the response data in the receiving buffer, and obtain the target network system information through the response data in the buffer.
[0026] In the present invention, by constructing the IP data packet whose payload is data in the TCP protocol format, the local TCP / IP protocol stack resources will not be occupied during the entire scanning process, and the data received by the remote target network will be considered as normal TCP protocol ...

The invention discloses a stateless TCP network scanning method, comprises the following steps: firstly separating a scanning module of an IP data packet from a receiving module; through the scanningmodule, constructing and sending an IP data packet carrying the TCP data to the target network according to the target network asset information, and recording the packet information sent out for comparison by the receiving module; waiting for the return of the response data by the receiving module; within a limited time, if the target network does not respond or the receiving module does not receive the response data, determining the situation to be non-responsive; and if the receiving module receives the response data of the target network, performing analysis according to the response dataand combining with a local information library to obtain target network system information. The stateless TCP network scanning method proposed by the invention not only can greatly improve the networkscanning speed, but also has the scanning precision, so that the problem of wane and wax scanning speed and scanning precision can be well solved.
Description
technical field [0001] The invention relates to a network scanning method, in particular to a stateless TCP network scanning method. Background technique [0002] With the continuous extension and popularization of various information networks, the security threats from the network are also increasing exponentially. Driven by various political, military, and economic interests, various types of network attacks emerge in an endless stream, and the network attack methods are also becoming more and more complicated. , diversification, and more targeted, the network security situation is becoming more and more severe. In order to be able to discover the enemy first and prevent problems before they happen, it becomes an important first step to maintain network security to conduct network searches on network targets and hosts of concern and collect relevant network information. [0003] Network scanning is used as a means of information system security protection. It is a securit...
