Problems solved by technology

Although the proxy or bastion machine method can filter out some attack content by detecting the data sent to the target IP, it is poor in identifying and protecting against seemingly "normal" attacks such as penetration attacks
Therefore, when a malicious user attacks the target IP by infiltrating the link connected to the target IP, the relevant technologies cannot provide effective protection.

Abstract

The invention relates to a session maintaining method and device, and the method comprises the steps: receiving a synchronization message sent by former selected service equipment after safety equipment is switched to service equipment, wherein the synchronization message is session information of interaction between the former selected service equipment and an upstream server and a downstream client; and maintaining the session with the upstream server and the downstream client based on the session information in the synchronization message. According to the invention, the method dynamically switches a link on the basis that the upper services are not affected, thereby enable the penetration attack and other attacks against the link not to be carried out, and effectively solving a problem that the related technologies are weak in protection capability during the prevention of attacks against the link.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method and device for maintaining a session. Background technique [0002] With the development of IP technology, IP-based attacks are becoming more and more rampant. In order to protect against IP-based attacks, related technologies propose a proxy or a bastion machine solution from two aspects of packet detection depth and detection frequency. Although the method of proxy or adding a bastion machine can filter out some attack content by detecting the data sent to the target IP, it has poor ability to identify and protect seemingly "normal" attacks such as penetration attacks. Therefore, when a malicious user attacks the target IP by infiltrating the link connected to the target IP, the relevant technologies cannot provide effective protection. Contents of the invention [0003] In order to overcome the problems existing in the related art, the present invent...
