Problems solved by technology

[0005] Embodiments of the present invention provide a network virus protection method, system, and device to solve the problem in the prior art that the business cannot be carried out normally due to the closure of the port anti-virus in the RPC-based communication process, and the problem caused by the blacklist-based anti-virus There is a problem that the signature library cannot be updated in time when there are new attack signatures

Embodiment Construction

[0023] At present, virus attacks at the Windows system level mainly come from RPC port overflow initiated by the network layer. Embodiments of the present invention propose a method based on whitelist filtering of RPC services to protect the system from overflow and virus damage. The client sends a request message based on the remote procedure call protocol to the server, and the request message includes the client identifier; if it is determined that the saved legal identifier set contains the client identifier, the server allows the request message to pass. In the embodiment of the present invention, because only requests containing information in the white list are allowed to pass, when the system business can be carried out normally, protection against unknown viruses can also be realized.

[0024] As shown in Fig. 1(a) and Fig. 1(b), it is a schematic diagram of the system structure of the embodiment of the present invention, the system includes a client and a server, wher...

Abstract

Embodiments of the present invention disclose a method for network virus protection, which includes: receiving a petition message which is based on remote process transferring protocol, in which the petition message contains marks for user terminals; allowing the petition message to pass through upon the confirmation of marks for user terminals being contained in legal mark concourse. The methodsin the embodiments of the present invention can improve system security, especially to a system with inconvenience of patches updating and vulnerabilities database updating. Embodiments of the present invention also provide a system and device for network virus protection.

Description

technical field [0001] The invention relates to data transmission technology in the communication field, in particular to a network virus protection method, system and device. Background technique [0002] Remote Procedure Call (RPC) is a protocol that requests services from remote computer programs through the network without knowing the underlying network technology. It can provide an internal process communication mechanism that allows programs running on a terminal to wirelessly seamlessly execute code in remote systems. The RPC protocol itself originated from the Open Software Foundation (OSF) RPC protocol, and RPC communication is a communication mechanism carried on the Service Message Block (SMB) protocol layer. [0003] At present, network viruses have had a very serious impact on RPC-based attacks, but there is no effective mechanism that can well prevent such network viruses from attacking RPC-based attacks. Especially at present, many business servers are not d...
