Introduction

The threats originating from the Internet are ever-increasing and far from being "under control". Modern security is designed to protect the vast range of business communication facilities from external as well as internal intruders, so-called "hackers". To this effect, various defensive mechanisms have been developed to protect internal data and systems from unauthorized access. Based on the simple principle that "the ultimate method to secure a network is to disconnect it", "Physical Separation" has been proposed for years as a high level security solution, which is expected to entirely prevent online intruder attacks by physically separating the communicating networks.

Since 2003, we proposed a novel implementation of "Physical Separation", named Lock-Keeper, which has been commercialized by Siemens Switzerland. In recent years, the patented Lock-Keeper system has been developed and improved to be more mature, dependable and applicable.

Research & Development

Our current research and development work in the area of "Physical Separation" is sepcially focus on the following topics:

Deployment of Lock-Keeper in Service-Oriented-Architecture (SOA).
Reconstruct Lock-Keeper using Concepts of Trusted Computing.
Lock-Keeper-based Online Police Station.
Secure Database Replication Module based on WS-Based Messaging Framework.
Lock-Keeper based IDS/IPS Solutions.
Securing VoIP Infrastructure and its Application using Lock-Keeper
Development of the Lock-Keeper Cluster System.
Performance measurement and comparison between the Lock-Keeper and other similar security solutions.
Authentication and access control based on the Lock-Keeper technology.
