Joint defence method and apparatus for network security, and server and storage medium

A method for network security joint defense, the method comprising:

• detecting network/system state information and user behavior information in a network/system environment according to an own defense policy to generate security log information;
• uploading the generated security log information to a security log sharing platform, wherein the security log sharing platform is configured to classify and summarize the uploaded security log information, to generate a plurality of event types of intrusion event information, and to push the plurality of event types of intrusion event information according to a preset rule;
• receiving at least one of the event types of intrusion event information which is pushed by the security log sharing platform;
• and
• generating a joint defense policy by taking the received intrusion event information as clue information.

A server, comprising:

• a memory;
• and
• a processor,
• wherein the memory stores computer executable instructions, which, when executed by the processor, cause the processor to perform following steps, comprising:
• obtaining security log information of a plurality of security devices, wherein the security log information includes intrusion event information violating an own defense policy of the security device obtained by the security device in a network/system environment;
• classifying and summarizing the intrusion event information included in the security log information according to preset intrusion event types;
• obtaining a corresponding relationship between each of the preset intrusion event types and a security device identification;
• and
• pushing the intrusion event information which is summarized according to the intrusion event types to the security device directed to by the security device identification having a corresponding relationship, so that the security device adjusts the own defense policy thereof according to the pushed intrusion event information.
