Embodiment Construction

[0034] Since the VNC protocol itself does not support file transfer, file transfer and auditing between the local device and the remote server cannot be implemented when the network security audit is performed through the bastion host. In the embodiment of the present invention, while realizing the remote desktop link from the remote server to the local device through the VNC protocol, the file transfer between the local device and the remote server is realized through FTP, so the bastion host can audit the files uploaded by the local device, and according to The audit result controls the file, which improves the security of the remote server.

[0035] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0036] figure 2 The network security audit process provided for the embodiment of the present invention specifically includes the following steps:

Abstract

The invention discloses a method, a device and a system for network security auditing. The method, the device and the system are used for solving the problem of poor security of a remote server in the prior art. The method includes that a bastion host sets up a remote desktop link from a remote server to local equipment through the VNC (virtual network computing) protocol, receives a file uploaded by the local equipment through the FTP (file transfer protocol), audits the file according to stored auditing strategies, transmits the file to be stored in the remote server when audit is eligible and abandons the file when the audit is ineligible. In the method, file transmission between the local equipment and the remote server is realized by the aid of the FTP, so that the bastion host can audit the file when receiving the file uploaded by the local equipment through the FTP and can control the file according to the audit results, and security of the remote server is improved.

Description

technical field [0001] The invention relates to the field of network security, in particular to a network security audit method, device and system. Background technique [0002] The bastion machine is a user-oriented centralized control operation and maintenance security audit product. Its main function is to control the centralized access of users and audit the entire operation behavior of users from login to logout. The user can use the device account on the local device to access target devices such as remote servers through the bastion host. The device accesses the corresponding target device. Among them, the local device and the remote server are distributed in two physically isolated networks, and the bastion host acts as a "middleman", that is, the user's operation data through the local device is forwarded to the remote server by the bastion host, and the data returned by the remote server Forward it to the local device through the bastion host.
