Data transmission control method and data transmission control device

Abstract

The embodiment of the invention discloses a data transmission control method and a data transmission control device, which is used for improving reliability of a blacklist filtration technology and lowering misjudgment rate. The method of the embodiment of the invention comprises the following steps that: a data message carrying an address of a host sent by the host is received; whether the host meets a filtering condition or not is judged according to the data message; if so, whether the address of the host is in a credible address list or not is judged; if so, the data message is responded and corresponding operation is carried out. The embodiment of the invention also provides the data transmission control device. The embodiment of the invention can effectively improve the reliability of the blacklist filtration technology and lower the misjudgment rate.

Description

technical field [0001] The invention relates to the communication field, in particular to a data transmission control method and a data transmission control device. Background technique [0002] With the wide application of the Internet and the continuous expansion of Internet interactive data, the security of customer data has become a concern of users. Therefore, more and more enterprises and individual users begin to use security products such as firewalls to protect their normal rights and interests through the anti-virus and anti-attack capabilities of these products. [0003] Different levels of security devices and their corresponding anti-attack capabilities determine their different application scenarios, which also provides users with a very large choice. Although there are a lot of high-end and low-end security equipment products, many similar or even the same attack defense strategies and methods are used in the large family of security equipment products. One ...

[0006] However, because the security device may need to be maintained during operation, and due to geographical restrictions, the network administrator may not be able to log in locally, but will use remote login to maintain the security device. If human error causes several consecutive login errors (such as wrong password input, etc.), the IP address of the remote host used by the network administrator will be blacklisted by the security device, and subsequent network administrators will not be able to pass through the host again. Maintenance of safety equipment, resulting in unknown and uncontrollable operating status of safety equipment within a certain period of time
