Intranet information protection device based on hardware waterproof wall

Abstract

The invention discloses an intranet information protection device based on a hardware waterproof wall. The device comprises a hardware control platform and a grading protection unit. The hardware control platform comprises an installation protection box. A wire connection port is embedded in the front surface of the installation protection box. A core processor is installed in the hardware control platform. The core processor is connected with a peripheral circuit. The network port of the core processor is connected with an Ethernet control module. The input end of the Ethernet control module is connected with a network transformer which is connected to the wire connection port. The grading protection unit is arranged in the core processor and comprises a user port layer, a safe service layer and a function module layer from top to bottom. The user port layer is connected with a physical port. The core processor is also connected with an intelligent alarm unit. According to the invention, through the combination of the software and the hardware, and the grading protection, the alarm function is added, the overall protection performance is effectively improved and user information safety is protected.

Description

technical field [0001] The invention relates to the field of waterproof wall technology, in particular to an internal network information protection device based on a hardware waterproof wall. Background technique [0002] The firewall is a concept relative to the firewall. It is an important tool to strengthen the internal security of the computer system, mainly to prevent the internal information from spreading outward. The firewall is an intranet monitoring system that is located in the internal network and monitors the security of the internal host at any time. situation; if fire protection refers to preventing external threats from spreading to the inside, waterproofing refers to preventing the leakage of internal information; specifically, the firewall technology is based on the internal network security theory, with data security as the core, using cryptography technology , PKI technology, operating system core technology, access control technology, audit trail techno...

[0002] The firewall is a concept relative to the firewall. It is an important tool to strengthen the internal security of the computer system, mainly to prevent the internal information from spreading outward. The firewall is an intranet monitoring system that is located in the internal network and monitors the security of the internal host at any time. situation; if fire protection refers to preventing external threats from spreading to the inside, waterproofing refers to preventing the leakage of internal information; specifically, the firewall technology is based on the internal network security theory, with data security as the core, using cryptography technology , PKI technology, operating system core technology, access control technology, audit trail technology and other technical means, implement security restriction protection on the storage, dissemination and processing of sensitive information such as confidential information, important business data and technical patents, and prevent Intranet data protection technology for sensitive information leakage; however, the existing firewall technology is not mature enough, and software firewalls alone cannot effectively respond to complex environmental requirements
