Based on DEVS virtualization security agent simulation modeling

One of the motivations for virtualization technology is the desire to the develop new architectures to enhance virtual network system security. This paper develops a description of a multi-agent architecture and defined five types of security agents in the virtualization environment. The major functions of the agents are: virtual network traffic detection, different trust levels applications authentication, Hypervisor self-security monitor etc. Each of the security agents cooperates with others to protect the system security. This paper, based on Parallel-DEVS and Agent-DEVS proposes a virtualization security agent modeling and simulation approach named VSA-DEVS. A set of abstractions are formulated and their designs are realized in COSMOS which is a DEVS framework integrated visual model development, model configuration and automatic simulation data collection. A sample simulation study is conducted to illustrate the use of VSA-DEVS in understanding some key design and performance aspects of the virtual network security multi-agents system.
