System and method for detecting computer security information based on U disc authentication

Abstract

The invention discloses a system and a method for detecting computer security information based on U disc authentication. The system comprises a data collecting terminal and a data analyzing processor, wherein the data collecting terminal comprises an embedded micro processor, an SDRAM memory module, a FLASH memory module, a serial communication circuit module, a USB interface circuit module, a network card, a touch screen driving circuit module, an authenticated U disc, a touch screen and a power supply managing module; the method comprises the steps of firstly, initializing system parameters; secondly, collecting data and performing encrypted signature; thirdly, securely storing and protecting a data file; fourthly, transporting the data; and fifthly, analyzing and processing the received data with the data analyzing processor to obtain an analytic processing result, and storing and displaying the result. The invention has novel and rational design, convenient implementation, convenient use and operation, high real-time capability and accuracy of data collection and transportation, high monitoring efficiency of the security of the computer, flexible and convenient use, strong practicability and high popularizing and applying values.

Description

technical field [0001] The invention relates to the technical field of computer information security, in particular to a computer security information detection system and method based on USB disk authentication. Background technique [0002] The current monitoring and inspection of computer security information mainly includes two categories: detection based on hardware devices and detection based on network protocols. [0003] The detection method based on hardware equipment is mainly to connect the monitoring interface (hardware) of each computer through a dedicated monitoring equipment to detect the power supply, fan, temperature, CPU status, etc. of the computer equipment. Once a predetermined condition occurs, the monitoring equipment Sound and light alarm. The main disadvantages of this detection method are: [0004] (1) The detection equipment and the computer to be tested must be provided by the same manufacturer, otherwise the hardware is not compatible, and diff...

AI Technical Summary

Problems solved by technology

[0004] (1) The detection equipment and the computer to be tested must be provided by the same manufacturer, otherwise the hardware is not compatible, and different computers can only use different monitoring equipment;

[0005] (2) The monitoring equipment and the monitored computer are connected through a dedicated line, so that the monitored computer can only be within a certain range;

[0006] (3) The monitoring equipment can only monitor the hardware, but cannot detect the running status of the software, especially for multi-tasking systems, the normal hardware cannot guarantee the normal software;

[0007] (4) The monitoring equipment must be manned

[0009] (1) The network protocol is too complicated and abstract, and the monitoring software is basically provided by foreign countries (such as: HP-OpenView), which is difficult for ordinary managers to grasp and play a big role;

[0010] (2) Generally, it is only used to detect the status of the network itself, such as traffic, congestion, bit errors, etc. However, the normality of the network cannot guarantee the normality of the application software;

[0011] (3) Many application software do not support the SNMP protocol, so the faults of these application software cannot be found;

[0012] (4) The monitoring software generates a large amount of monitoring data, and it is difficult to process the data;

[0013] (5) The monitoring equipment must be manned
