Embodiment 1

[0050] figure 1 Embodiment 1 of a message processing method is shown, including:

[0051]Step 101, use any one of three preset methods to process the input message to obtain the first message. The three preset methods are respectively: extracting the IP packet header of the message or the fixed position of the load Packet whose signature matches the first preset feature, extracts packets whose signature anywhere in the payload matches the second preset signature, and extracts packets whose signature range in the packet payload matches the third preset signature ;

[0052] Step 102, processing the first message in any one of the other two ways among the three preset ways to obtain a second message;

[0053] Step 103, processing the second message according to the remaining preset methods among the three preset methods to obtain a third message;

[0054] Step 104, sending the first message, the second message and the third message to a preset location for storage.

[0055] I...

Abstract

The embodiment of the invention provides a message processing method and a message processing device. The method comprises the following steps: using any one of three preset modes to process input message to acquire first message; using any one of the other two modes in the three preset modes to process the first message to acquire second message; using the rest preset mode in the three preset modes to process the second message to acquire third message; and sending the first message, the second message and the third message to a preset position to be stored, wherein the three preset modes comprise: extracting the message of which feature code at a message IP packet head or a load fixing position accords with a first preset feature, extracting the message of which feature code at any position in message load accords with a second preset feature, and extracting the message of which feature code range in the message load accords with a third preset feature.

Description

technical field [0001] The present invention relates to the technical field of network communication, and more specifically, to a message processing method and device. Background technique [0002] With the continuous development of network technology, the sharing of network resources between each other has greatly improved people's work efficiency, and people's dependence on the network is also increasing. Malicious access or attacks on terminals through the network will damage the terminal's security. For normal use, it is necessary to screen and filter the accessed packets. For example, in the face of the increasingly serious situation of spam, it is necessary to filter spam. The filtering method is to filter and filter services based on the 5-tuple of IP packets. The 5-tuple of IP packets refers to the destination IP address, source IP address, protocol type, destination port and source port. [0003] Due to the increasing complexity of malicious attack technology, the...
