Research and Realization of Security Policy in IPSec Based on ID3 Algorithm

IPSec is a policy-driven security mechanism. How to react on the diversity of network security and quickly generate corresponding security policy is one of the core issues of IPSec. This article introduces the traditional IPSec security policy and demonstrates an improved mechanism of implementing the IPSec security policy. Secondly, it constructs the security policy model based on ID3 algorithm by adding the policy engine components for enhancing efficiency and flexibility of security policy management for IPSec. Finally, through a case analysis, it describes the dynamic generation process of IPSec security policy.
