USB interface information security prevention and control method and system

Abstract

The invention discloses a USB interface information security prevention and control method and system, and the method comprises the steps: external USB equipment connects to a security management andcontrol module, and the security management and control module sends a connection instruction to a management machine; the management machine receives the access instruction, judges whether the security management and control module is started or not, and sends an authority instruction to the security management and control module; the security management and control module controls the on-off ofan internal switch according to the authority instruction, and sends the on-off information of the internal switch to the management machine, thereby achieving the physical management and control of the access and use authority of all USB interfaces of the monitoring system host, effectively preventing and controlling an information safety problem, and guaranteeing the safe and stable operation ofpower monitoring.

Description

technical field [0001] The present invention relates to the technical field of electronic information security, in particular to a USB interface information security prevention and control method and system. Background technique [0002] As computers and various electronic devices are more and more widely used in daily life, USB interfaces are used more and more frequently, such as mouse, keyboard, U disk, mobile hard disk, external sound card, power bank, electronic cigarette, etc. All use the USB interface, and plug and play. According to statistics, except for the network adapter interface among all physical interfaces, the USB interface has the highest efficiency in spreading malicious virus programs, and the USB protocol can also be used by attackers to attack, so the USB interface has become a target for the spread of many malicious programs and network security attacks. carrier. [0003] The types of attacks via USB are mainly divided into the following categories: ...

Problems solved by technology

As the "eyes" of the power system, the monitoring system plays an extremely important role and is crucial to the information security prevention and control of the USB interface of the monitoring system host. However, the above two protection measures cannot effectively avoid information security under the condition of meeting the work requirements. Therefore, it is of great significance to propose a new method to prevent and control the information security of the USB interface
