Problems solved by technology

In this application, traditional network interception methods cannot intercept network data
[0005] Secondly, installing different software with traditional network interception technology on the same computer may cause different degrees of access conflicts, causing software to interfere with each other

specific Embodiment

[0060] Such as Figure 6 , a bank customer data security management project, the anti-leakage system divides the network into an internal network and an external network. Email communication between the internal network needs to be encrypted and sent, and email communication between the internal and external network needs to be audited and then sent in clear text.

[0061] Outgoing email encryption policy: email client email attachments are encrypted, and attachments and email information are uploaded to the anti-leakage server for auditing.

[0062] Mail receiving decryption strategy: the mail client receives attachment encryption, and the attachment and mail information are uploaded to the anti-leakage server for auditing.

[0063] WEB Outgoing Encryption Policy: Configure the OA email address to the HTTP outbound control policy, and upload attachments and email information to the anti-leakage server for auditing when emails are sent and received.

[0064] The mail server ...

Abstract

The invention discloses a data leakage prevention method and system based on a TDI interface layer. The system comprises a strategy generation module which is used for generating at least one data externally sending strategy and a data receiving strategy; a strategy loading module which is used for loading the data externally sending strategy and the data receiving strategy; a TDI drive module which is used for intercepting an IRP data packet when an application needs to send or receive a network data packet, filtering the IRP data packet and sending the filtered IRP data packet to a redirection module; and a redirection module which is used for analyzing the intercepted IRP data packet and carrying out data processing according to the configured data externally sending strategy and data receiving strategy. Through application of the scheme, various installing environments are adapted and data leakage is prevented.

Description

technical field [0001] The invention relates to the field of information security, in particular to a data leakage prevention method and system based on a TDI interface layer. Background technique [0002] With the rapid development of information science and Internet technology, security issues have intensified, and network and information security have received unprecedented attention. Among them, the data leakage prevention system, as a means of terminal protection for data security, requires data security management and control. In this regard, Beijing Mingchao Wanda Technology Co., Ltd. proposes an application method for network interception of the data leakage prevention system at the TDI interface layer. [0003] At present, traditional network interception is generally realized through SPI (Service Provider Interface) packet interception technology or hook network communication function, and the internal implementation is to call winsock network interface by loading...
