Embodiment Construction

[0028] figure 1 It is a schematic diagram of the system framework of the embodiment of the present invention. Embodiments of the present invention are deployed in figure 1 In the mail detection module of the mail filtering system shown, the mail filtering system is deployed on the power office terminal. The power office terminal is an ordinary office computer. When an employee uses a mail client (such as Hotmail, Firefox, etc.) or a Web browser to log in to the external network mail server to send mail, the mail filtering system will check the mail in real time before sending it. Capture and process, and only allow those emails that do not contain power-sensitive keywords to be sent normally.

[0029] The mail filtering system mainly includes three modules: mail interception module, mail detection module and early warning module. The mail interception module is mainly responsible for capturing the mail information sent by the user in real time, and sending the information t...

Abstract

The invention discloses a real-time detection method for an electric power sensitive mail based on multimode matching. The method mainly comprises the following steps of (1) analyzing an electronic mail sent by staff in real time, and extracting mail information; (2) initializing a multimode matching engine by using set electric power sensitive keywords; (3) matching sensitive keywords for a mail subject, a mail body, an attachment subject and an attachment body by utilizing the multimode matching engine; (4) judging whether the mail is the electric power sensitive mail according to a matching result, if so, intercepting the electric power sensitive mail in real time and sending alarm information, and otherwise, normally sending the mail. According to the method, the electronic mail sent by the staff can be analyzed on an electric power office PC (Personal Computer) terminal, the sensitive mail which probably contains electric power confidential information is detected, and a mail interception module is informed of real-time interception, so that a confidential document of an electric power department is effectively prevented from being leaked, and the data safety of an internal electric power system and a terminal is protected from the source.

Description

technical field [0001] The invention relates to the field of information security in the electric power industry, in particular to a real-time detection method for electric power sensitive mails based on multi-mode matching. Background technique [0002] With the continuous advancement of power system informatization and networking, the information security situation faced by State Grid Corporation is becoming increasingly severe. Sensitive data within the company not only faces attacks from external environments such as viruses and Trojan horses, but also internal threats caused by intentional destruction and leakage by internal personnel are gradually increasing. According to the survey reports of the Computer Security Institute (CSI) over the years, although in terms of quantity, the frequency of external cyber attacks far exceeds that of internal leaks, but in terms of losses caused, internal The threat is far greater than the external threat. From the "Prism Gate Inci...
