Security and protection monitoring big data processing method and system based on cloud computing

Abstract

The invention discloses a security and protection monitoring big data processing method and system based on cloud computing. The method comprises the following steps: obtaining security and protection monitoring data of an Internet of Things node; dividing the obtained security and protection monitoring data into first security and protection monitoring data and second security and protection monitoring data according to a set security threshold; sending the first security and protection monitoring data to a block chain platform for data processing; and sending the second security and protection monitoring data to a cloud platform for data processing. According to the security and protection monitoring big data processing method and system, the second security and protection monitoring data with relatively low security requirements are sent to the cloud platform for data processing, thereby ensuring the security and protection monitoring big data processing efficiency; meanwhile the first security and protection monitoring data with relatively high security requirements are sent to the block chain platform for data processing, and DDOS attack is defended by the features of openness, transparency and non-tempering of the block chain technology, thereby eliminating the potential safety hazards caused by the DDOS attack to the cloud platform and the distributed Internet of Things nodes, and being securer. The security and protection monitoring big data processing method and system can be widely used in the field of security and protection.

Description

Technical field [0001] The invention relates to the field of security, in particular to a cloud computing-based security monitoring big data processing method and system. Background technique [0002] In the field of security, the issue of information islands is very prominent. In a city, there are both camera monitoring equipment installed by the public security department and camera monitoring equipment installed by various units. The monitoring data generated by these devices or systems is difficult to achieve interconnection and intercommunication, resulting in the phenomenon of information islands, "you can only see the trees but not the forest." In recent years, the construction of smart cities with cloud computing and the Internet of Things as the core put forward the concept of big security, trying to integrate these isolated monitoring information, so as to achieve networking and sharing. However, the huge amount of security monitoring data causes huge consumption of c...

Problems solved by technology

[0005] At present, Hadoop-based cloud computing technology has been successfully applied in the field of security monitoring big data, which has greatly improved the processing efficiency of security monitoring big data, but its essence is a distributed processing method, which is difficult to resist DDOS attacks (distributed denial of service attack), not secure enough

In addition, in the field of security monitoring, most of the security monitoring big data comes from distributed IoT nodes (such as camera nodes, etc.), and the current distributed IoT nodes are also difficult to resist DDOS attacks, and there are also security risks
