Embodiment

[0118] After many years of digital reform in a national surveying and mapping unit, the surveying and mapping map has been fully digitized. Digital map data is the core asset of the unit, and maps with different precision have different confidentiality levels. The unit strictly prohibits the digital maps within the scope of confidentiality from flowing into the Internet from within the surveying and mapping unit. Digital map data is highly specialized, and ordinary security equipment cannot recognize it at all, and it is impossible to make fine-grained distinctions based on attributes such as accuracy. In this demand scenario, the unit first provides the relevant information of the electronic map data, such as map file samples, map file format description, etc., and then programs are programmed on the programmable firewall by professional security personnel or developers of the information department of the testing unit Development, to realize the identification of the electr...

Abstract

The present invention relates to a logic code detection method, device and electronic equipment of a programmable firewall, comprising: importing the network application flow sample corresponding to the logic code into an emulator as input data, and the emulator reads the For each IP data packet of the network application traffic sample, analyze and process the network application traffic sample; write the logic code for the network application according to the sample analysis and processing results, and load it; check the syntax of the loaded logic code, according to Check the results to determine whether to modify the logic code; execute the corresponding logic code that has passed the syntax check on the network application traffic sample, and obtain the result of the logic code simulation operation of the network application traffic sample; compare the operation result with the effect expected by the user For comparison, if the two running results are consistent, save the logic code to the code library of the emulator, if the two running results do not match, the logic code will be returned for modification.

Description

technical field [0001] The invention relates to the technical field of network security applications, in particular to a logic code detection method, device and electronic equipment of a programmable firewall. Background technique [0002] Programmable firewalls need to write different logic codes for each application, and different users focus on different applications, and the application implementation methods vary widely. Programmable firewalls provide users with private or customized applications in the form of security services, enabling users to expand application processing and analysis capabilities without upgrading the system or replacing hardware. [0003] In essence, a firewall is an embedded system that combines software and hardware to prevent threats to intranet resources and information security, such as viruses, unauthorized user access, and hackers. [0004] Ordinary application-layer firewalls are not well suited for in-depth analysis of all applications,...
