Collaborative Defense System for Security Policies in Cloud-Edge Scenarios Based on Virtualization

With the continuous advancement of cloud and edge computing technologies, security challenges in cloud-edge collaborative environments have become increasingly pronounced. This paper presents a comprehensive analysis of the limitations inherent in traditional network security defense systems for intelligent device clusters and explores strategies to enhance security in these environments through collaborative defense mechanisms. By employing cloud-edge collaborative management of security resources, establishing a security resource pool, and leveraging virtualization platforms alongside Security Orchestration, Automation, and Response (SOAR) platforms for security orchestration, this study proposes a robust and efficient solution to address complex cyber threats. The analysis demonstrates that the proposed collaborative defense mechanism effectively mitigates issues such as uneven resource allocation and isolated functionality in traditional systems, thereby significantly improving the network security of intelligent device clusters.
