Abstract

The invention relates to the technical field of network protection, in particular to a threat discovery model construction technology based on a digital certificate, which comprises the following steps: (1) detecting a port of a specified IP end: (1.1) acquiring detailed information of a port certificate; (1.2) acquiring a connection response time difference; (1.3) acquiring port connection home page information; (1.4) acquiring information of other ports; (2) analyzing the acquired data: (2.1) analyzing the certificate; (2.2) calculating the hyper-connection amount of the home page; (2.3) analyzing the connection response time; (2.4) carrying out data size analysis on home page information; and (2.5) carrying out screening analysis on other correspondingly detected ports. According to theinvention, a suspicious secret-stealing fingerprint analysis model can be constructed, and targeted monitoring and discovery of a specific scene are realized.

Description

technical field [0001] The invention relates to the technical field of network protection, and the specific field is a digital certificate-based threat discovery model construction technology. Background technique [0002] In recent years, the network facilities and data of key units in our country have been frequently attacked and stolen by overseas spy agencies and anti-communist hacker organizations. Overseas spy organizations use a series of extremely advanced attack methods such as APT attacks and 0day vulnerabilities to easily break through traditional Network security protection facilities attack, control, steal secrets, and destroy our important and sensitive departments and key infrastructure, while network security responses are always in a situation of hindsight and passive attack, lack of high-level attacks originating from abroad The ability to conduct timely response and early warning. Contents of the invention [0003] The purpose of the present invention i...
