Method for preventing illegal access from bus line

Abstract

This invention relates to a method for preventing illegal infall from bus line, which sets an identifying module with a microprocessor and a storage unit between a bus line and several electronic components, in which, said storage unit stores a signal reference list including several stored signals and identification codes and each signal is matched to an identification code, when said microprocessor receives a transmission signal output from the bus line and the identification code and that matched to the stored signal are the same , then the transmission signal passes through the identification module so as to prevent illegal infall by various data packets through the bus line.

Description

technical field [0001] The invention relates to a method for preventing illegal intrusion from a bus, in particular to a method for identifying signals output from a bus to prevent various data packets from intruders passing through the bus. Background technique [0002] In recent years, due to the rapid growth of the Internet and the rise of e-commerce, people have infinitely good prospects for the possible business opportunities brought by the Internet. However, when enjoying the convenience brought by information technology, there are also Many potential security problems and the threat of network hacker attacks have made network security issues more and more important. Generally speaking, network hackers have different purposes and methods of attacking, and they may invade computer systems to steal or tamper with web page data. The purpose is not to invade the computer system to steal or tamper with web page data, but to adopt a so-called distributed denial of service at...

Problems solved by technology

[0005] Compared with general systems that are equipped with security mechanisms for network traffic monitoring and network access control, such as the protection measures of the aforementioned firewall, general systems do not have any protection measures for the system management bus, making various data Packets can be easily transmitted to these electronic components through the system management bus, which will cause the data in the electronic components to be changed, or the electronic components to be damaged, and even affect the system to cause instability or crash. Therefore, if A security mechanism that can prevent this security hole will more completely ensure the security of the system
