Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular to a value-based hierarchical security strategy and a hierarchical cloud storage system for ecological compensation data. Background Art

[0002] Traditional security detection methods often rely on physical hardware, such as independent servers and network devices. This results in fixed configuration and limited scalability of resources. In traditional technologies, the allocation and management of resources is cumbersome and cannot quickly meet the needs of different workloads. There are challenges in the sharing and isolation of physical resources in traditional technologies. Although physical isolation measures can be used, such as different servers and network segmentation, such isolation is usually not flexible and granular enough. This may lead to increased security risks and potential attack surfaces when resources are shared, and security and privacy issues in traditional technologies are often more vulnerable to attacks. For example, physical servers and network devices are vulnerable to physical access attacks, and data transmission and storage in traditional technologies may be more vulnerable to the risk of eavesdropping and data leakage. Summary of the invention

[0003] The technical problem to be solved by the present invention is: in order to overcome the above-mentioned problems, a hierarchical security strategy and a hierarchical cloud storage system for the value of ecological compensation data are provided, which solve the above-mentioned problems.

[0004] The present invention solves the technical problem by adopting the following technical solutions:

[0005] First, ensure the security isolation of virtual networks. Use technologies such as virtual network security groups and virtual firewalls to limit the communication between virtual machines and between virtual machines and external networks, reduce potential attack surfaces, and perform security checks on virtual machine images in the resource pool, including verifying the integrity and credibility of the images, and performing malware scanning to ensure that the image files do not contain known viruses, Trojans, or malware. Monitor the behavior of virtual machines in the resource pool and use intrusion detection systems (IDS) or behavioral analysis technologies to detect abnormal behavior, malicious activities, or potential security threats. Establish a baseline for normal behavior and use machine learning algorithms to identify abnormal behavior and new attacks. Design strict resource access control policies, including authentication, authorization, and permission management, to ensure that only authorized users and services can access virtual machines and sensitive data in the resource pool. Implement measures such as multi-factor authentication, strong password policies, and regular password changes to enhance access security. Establish a comprehensive security audit and logging mechanism to audit and analyze key events, access logs, and operation records in the resource pool to detect potential security issues and trace security incidents. Use log analysis tools and security information and event management (SIEM) systems to monitor and analyze log data in real time, perform vulnerability scans regularly, perform vulnerability scans on the operating system, virtualization software, and key applications in the resource pool, and use vulnerability scanning tools and automated patch management systems to promptly discover and patch known security vulnerabilities, reduce the risk of attack, conduct continuous security assessments and improvements, regularly perform security checks and vulnerability scans on the resource pool, track new security threats and technical vulnerabilities, and update security controls and policies to maintain the continuous security of the resource pool. By taking these steps and measures, you can enhance the virtualization security of the computing power network security resource pool, reduce potential security risks, and protect the virtual machines and sensitive data in the resource pool from attacks.
