Abstract

The embodiment of the invention provides a mail blocking method and device, and the method comprises the steps that a terminal obtains the latest configuration information from a server, updates a local keyword strategy according to the latest keyword strategy, obtains the updated keyword strategy, intercepts a mail when monitoring that a mail tool sends the mail, and transmits the intercepted mail to a server through the server; the mail content of the mail is detected according to the updated keyword strategy, whether keywords exist in the mail content of the mail is determined and if so, the mail tool is blocked from sending the mail. Therefore, the mail can be sent through the application layer intervention mail tool, a system blue screen cannot be caused, the mail is sent through theapplication layer intervention mail tool, and at the moment, the mail is not encrypted through a specified protocol, so that the mail sent under a non-encryption protocol and an encryption protocol can be dynamically intercepted; therefore, the problem that in the prior art, only non-encryption protocol mails can be analyzed, and consequently the types of intercepted mails are limited can be solved.

Description

technical field [0001] The embodiments of the present application relate to the field of computer technology, and in particular, to a method and device for blocking emails. Background technique [0002] With the rapid development of computers, more and more companies begin to communicate and interact through email tools. However, due to the uncontrollability of email content, employees can send important corporate information through email, which poses serious hidden dangers to the security of internal data. . For example, after an employee sends important information through an email tool, the email record can be deleted, which makes it impossible to trace who caused the leak, or the employee has already sent the important information, even if it is traced to the employee who sent it, but the loss of the enterprise has already been caused. . [0003] The existing mail blocking method is to block the mail by blocking the operation of the mail tool or by blocking the networ...
