Embodiment Construction

[0066] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementations described here are only used to illustrate and explain the present disclosure, not to limit the present disclosure.

[0067] As mentioned in the background art, a firewall is usually implemented using a multi-core processing mechanism under a heterogeneous platform. specifically, figure 1 As shown, the firewall includes a plurality of CPUs, and part of the CPUs (forwarding CPU 10) runs in the user mode and can be used to receive log messages from the network card 20; part of the CPUs (processing CPU 30) runs in the kernel mode and communicates with the forwarding CPU 10. After receiving the log message, the log file message can be reviewed and analyzed, so as to perceive the access risk of the media file. However, with the increase of log files, the data of log messages that the firewa...

Abstract

The disclosure relates to a media file security situation awareness method and a firewall, which are applied to a firewall. The firewall includes a plurality of analysis cores, and each analysis core is used to receive log messages from at least one type of user, and different analysis The user types corresponding to the cores are different from each other, and the method includes: each of the analysis cores determines the type of the log message according to the port number corresponding to the currently received log message; if the type of the log message is a preset type, obtain the user type of the target user corresponding to the log message and the media file visits corresponding to the log message; update the visits information of the target user according to the media file visits; The access volume information of each user of the user type of the target user is used to determine whether there is any abnormality in the access of the target user to the media file.

Description

technical field [0001] The present disclosure relates to the field of computer technology, in particular to a media file security situation awareness method and a firewall. Background technique [0002] For security vendors, in addition to ensuring the safe transmission of media file information, the safe storage of media files after downloading to the local file system, and ensuring that the media files will not be leaked, it is also necessary to review and analyze the access logs of the media files, so that Perceive risks and notify users in time to further improve the security of the media file system. In the prior art, a firewall is usually set at the front end of the media file server, so as to realize the above-mentioned process through the firewall. [0003] With the development of computer technology and the increase of users, the firewall needs to process a large number of log files. A firewall usually uses a multi-core processing mechanism under a heterogeneous p...
