Security threat analyzing method based on service data stream model

Abstract

The invention relates to a security threat analyzing method based on a service data stream model. The method includes the steps of establishing the service data stream model, decomposing an information system, analyzing key service flow, recognizing and grading sensitive data, and analyzing the security threat. According to the technical scheme, by establishing the key service data flow link of the information system on the basis of the service data stream model, introducing the security grades of the sensitive data, and recognizing the security threat of each key service flow and conducting formal representation according to the key service data flow model, a user can be helped to design the security threat analysis better conforming to the system service flow, and therefore the overall security of an application system is enhanced.

Benefits of technology

This patented technology helps improve the efficiency of analyzing complex systems for potential attacks or vulnerabilities related thereto. It involves starting off-line and creating an analytical framework through which different types of business processes may be identified and evaluated separately without affecting their main purpose. By doing this, it provides better understanding about how these important assets interact within them, making sure they meet certain standards before being released into public use.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the safety and reliability of electronic devices that store data securely during their lifespan (their ability to protect against potential damage caused by external factors). Current methods involve manual review and assessment after each new device starts up, which can be time-consuming and expensive due to its large size and complexity.
