Computer USB interface information security prevention and control method and system

Abstract

The invention discloses a computer USB interface information security prevention and control method, which comprises the steps that external USB equipment is connected into a security management and control module, and the security management and control module sends a connection instruction to a management machine; the management machine receives the access instruction, controls a computer camerashooting unit to be started and judges whether the user is an authorized person or not, and if so, detection is passed, and if not, permission detection is conducted again through a detection module;the detection information is sent to the management machine; and the management machine controls the on-off of a switch in the security management and control module according to the detection information. According to the computer USB interface information security prevention and control method, the computer host receives the on-off information and sends the on-off information to the managementmachine, and access permission of all USB interfaces of the computer host is physically managed and controlled, and meanwhile, an intelligent judgment means is applied to determine the access checkingpermission, and the information security problem is effectively prevented and controlled, and the security of computer storage data is guaranteed.

Description

technical field [0001] The invention relates to the technical field of electronic information security, in particular to a computer USB interface information security prevention and control method and system. Background technique [0002] Along with the application of computer more and more widely in daily life work, the use of USB interface is also more and more frequent, 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: USB phishing, HID cloaking, USB 0-day exploits, and USB-based power attacks. USB phishing generally attacks or infects target computers and ele...
