Problems solved by technology
[0005] For this reason, the first purpose of this application is to propose a host IP address conversion method to realize the conversion of the real IP address transparently transmitted in the network connection data and obtain the real IP address, so that the back-end business system can Accurately locating the real network attacker provides conditions for improving the security detection capability of the back-end business system, and solves the problem that the source IP proxy / source IP NAT scenario in the prior art cannot obtain the real attacker IP information, resulting in The problem of being unable to locate the real attack source

The invention provides a host IP address conversion method and device, computer equipment and a storage medium. The method comprises steps of obtaining a plurality of pieces of first IP information ina preset time period, dividing all first IP information containing the same source IP address into a first IP group so as to generate at least one first IP group corresponding to a plurality of pieces of first IP information, judging whether unvarnished transmission IP fields meeting a preset unvarnished transmission condition exist in other fields of all the first IP information in each first IPgroup or not, determining at least one second IP group with the unvarnished transmission IP fields in the at least one first IP group, and according to all destination IP addresses corresponding to the at least one second IP group and the unvarnished transmission IP addresses corresponding to the unvarnished transmission IP fields, performing unvarnished transmission; and performing host addressconversion on the source IP address corresponding to the at least one second IP group. According to the method, conversion of the unvarnished transmission real IP address in the network connection data can be realized, and conditions are provided for improving the security detection capability of a rear-end service system.
Description
technical field [0001] The present application relates to the technical field of network security, in particular to a host IP address conversion method, device, computer equipment and storage medium. Background technique [0002] Network-based security detection technology is one of the most common security detection technologies. When analyzing security events through the network, IP information such as source IP address and destination IP address is the core data for judging the attacker and the attacked assets. [0003] In the source IP proxy / source IP NAT (Network Address Translation, Network Address Translation) scenario, the source IP will be converted. If the converted IP is collected during security detection, the results of security analysis will not be obtained. The real attacker IP information cannot be accurately located. Contents of the invention [0004] This application aims to solve one of the technical problems in the related art at least to a certain ex...
