USB interface anti-violation external connection locking device

Abstract

The invention discloses a USB interface anti-violation external connection locking device, and the device comprises a USB expander and a fuse box; the two ends of the USB expander are provided with a first external connection end and a second external connection end respectively, the first external connection end is connected with a USB interface of computer equipment, the fuse box seals the second external connection end, the fuse box is provided with a locking door corresponding to an external interface of the second external end, and the fuse box is provided with a lock capable of locking the locking door. According to the invention, unused USB interfaces of computer equipment are blocked by glass cement and the like, the rest of interfaces are led out to a desktop through the USB expander and then are controlled, and specifically, the second external connection end of the USB expander is arranged in the fuse box with a locking function, so the possibility that an intranet USB is connected with any external electronic equipment is cut off, and the device is prevented from being used by people except equipment owners.

Description

technical field [0001] The invention belongs to the technical field of electric power information security, and in particular relates to a USB interface locking device. Background technique [0002] With the development of electric power informatization, information security has become an important factor to ensure the stable and safe operation of the power grid. With the continuous development of the Internet, the wide application of new technologies, and the continuous improvement of the deepening and application of State Grid information, power companies are increasingly dependent on informatization, and the importance of information security has gradually become prominent. However, with the incidents of "illegal outreach" on the internal information network of the State Grid, the originally closed system environment is exposed to the Internet, and the internal network will face many threats such as viruses, Trojan horses, unauthorized access, data leaks, and data tamperi...

Problems solved by technology

However, with the incidents of "illegal outreach" on the internal information network of the State Grid, the originally closed system environment is exposed to the Internet, and the internal network will face many threats such as viruses, Trojan horses, unauthorized access, data leaks, and data tampering. a variety of network security threats; work documents, important information and other sensitive data are illegally obtained, resulting in leaks; bringing viruses and Trojan horse programs into the intranet also provides opportunities for hackers to attack, which may cause the internal network and application systems of the power grid to crash. crash

This not only causes information security incidents, but also brings security risks to enterprise information security.
