Design and Implementation of Efficient One-Way Isolation System Based on PF_RING

The field of information security of data privacy issues in the existing network deployment environment is facing the more and more challenges. The one hand, the physical isolation of high-security domain is specifically requested by the State Secrecy Bureau, On the other hand, the challenge of security and efficiency of high-security domain when low security domain importing data to it. This paper is based on more than the status quo, not only analysis of the traditional isolation devices and introduced the spectrophotometric mechanism into the isolation system, but also use PF_RING technology to optimize the system and designed one-way transmission protocol, designed a new one-way isolation system. This system has a fundamental solution to the problem of data leakage, improved the efficiency of one-way import under the premise of protecting the security.
