Abstract

The invention discloses a safety protection method and system, and relates to the field of the communication network technology, and can solve the problem of a high resource occupancy rate caused by an existing safety protection method. By use of the embodiment of the invention, an anti-malicious-software driver is used for receiving a file access request, a file event is generated according to the file access request, the file event is sent to an antivirus engine through a safe API (Application Program Interface) library interface, the antivirus engine calls the safe API library interface to read the contents of a file to be accessed from a shared memory, the contents of the file to be accessed are scanned, and a scanning result is sent to the anti-malicious-software driver; and when the anti-malicious-software driver determines that a scanning result is that malicious software is not contained, the file to be accessed permits to be accessed, and when the anti-malicious-software driver determines that the scanning result is that the malicious software is contained, the file to be accessed is subjected to antivirus processing. The scheme provided by the embodiment of the invention is suitable to be adopted when a KVM (Kernel-based Virtual Machine) system is subjected to safety protection.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a method and system for security protection. Background technique [0002] At present, KVM (Kernel-based Virtual Machine, system virtualization module) virtualization technology has been widely used. In order to improve the security of the KVM virtualization system, security devices such as firewalls, antivirus walls, and intrusion prevention systems can be deployed at the network layer. To isolate the internal and external networks, and install anti-virus software in each operating system to filter malicious programs from the external network, monitor illegal access to the server, and ensure the safe operation of the core server. [0003] However, anti-virus software will be installed in each operating system virtualized by a physical machine. If the preset scan function is enabled for the anti-virus software, when the specified time is reached, the anti-virus sof...
