Embodiment 1

[0041] Such as figure 1As shown, the cloud computing-oriented intrusion detection system with cognitive capabilities includes a cognitive detection module: data preprocessing is responsible for collecting data streams in the network and generating data stream files in a certain format. Data packet detection performs packet detection on the preprocessed data flow, and judges whether the data flow is a known attack form according to the established cognitive rule base, and establishes an attack signature that meets certain rules for the known attack. Including processing method, transport layer protocol type, application layer protocol type, port number, IP address range, remarks, etc.

[0042] Cloud cognitive reasoning learning module: The cloud reasoning learning module evaluates the possibility of intrusion. The input of the reasoning machine is divided into two parts: one part is during intrusion detection (online judgment), and the collector provides the collected network ...

Abstract

The invention discloses a cloud computing environment oriented cognitive intrusion detection method, comprising a data preprocessing unit, a data packet detection unit, a database, a cognitive rule base, an intrusion detection engine unit, an event processing unit, a cloud cognitive inference machine and a statistic analysis unit. A cloud cognitive inference learning module optimizes a feature vector through adoption of a genetic algorithm, so the required training time and monitoring time are shorter than those of other methods; a real-time online detection capability is high; and large-scale parallel computing and large data volume processing capabilities are carried out through full utilization of cloud computing in a cloud computing environment; the operation capability is greatly improved; and a system is relatively safe and efficient.

Description

technical field [0001] The invention belongs to the field of cloud computing, in particular to a cognitive intrusion detection method for a cloud computing environment. Background technique [0002] Cloud computing has become a hot topic in the current IT industry, but the development of cloud computing also faces many key issues, and security issues are the first to bear the brunt, and with the continuous popularization of cloud computing, its importance is gradually increasing, which has become a constraint cloud computing. A core element of computing development. Cloud security challenges are reflected in three aspects: (1) data security, including data encryption and decryption, access control, transmission security, etc.; (2) service security, including server security, secure single sign-on, identity authentication, trust model, etc.; (3) The security monitoring system is used to defend and prevent malicious intrusions, and to ensure the data and privacy security of a...
