Embodiment Construction

[0055] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0056] The objects processed by the present invention are cloud service logs, see figure 1 As shown in the cloud service log records, each cloud service log comes from the MR job module, SQL job module, etc. in the storage / computing layer of the big data computing service (MaxCompute). Big Data Computing Service (MaxCompute) is the enterprise version of Alibaba Cloud Apex Cloud, on page 11 of the "Big Data Computing Service Product Introduction" published on November 18, 2020. Product version: V3.12.0.

[0057] The cloud service log is recorded as Log, and multiple cloud service logs are expressed in the form of a collection and recorded as a cloud service log set in:

[0058] log 1 Indicates the first cloud service log.

[0059] log 2 Indicates the second cloud service log.

[0060] log i Indicates the i-th cloud service log.

Abstract

The invention discloses a construction method of a time-varying state space vector for cloud service event connection, which is used for revealing connection between cloud service events so as to facilitate safety judgment of tracing cloud service events. The method comprises the following steps: syntactizing a cloud service log; constructing a cloud service event ontology; setting a mapping rule according to the field meaning, the BNF and the standard score (Z score); and constructing and generating a state space vector of the cloud service event. Compared with the existing vector construction technology, the method provided by the invention has the advantages of fewer used resources, lower complexity and high operability. The method has the advantages that the method does not depend on a word bank or word frequency, character strings can be processed, unstructured logs can be processed, and especially uncertain cloud service logs can be processed.

Description

technical field [0001] The present invention relates to the technical field of network security of cloud servers, and more particularly refers to a method for constructing time-varying state space vectors oriented to cloud service event linkage. Background technique [0002] Cloud server (Elastic Compute Service, ECS) is a computing service that is simple, efficient, safe and reliable, and has elastically scalable processing capabilities. Its management method is simpler and more efficient than physical servers. Users can quickly create or release any number of cloud servers without purchasing hardware in advance. Cloud servers help users quickly build more stable and secure applications, reduce the difficulty of development and maintenance and overall IT (Internet Technology) costs, and enable you to focus more on core business innovation. Cloud service logs refer to the records of a process and experience generated when ECS is running. [0003] Network security refers t...
