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. Here, we proposed a novel security solution named Lock-Keeper, which can provide data transfer by physically separated connections.
Based on the simple principle that "the ultimate method to secure a network is to disconnect it", the Lock-Keeper can guarantee higher levels of security and entirely prevent specific intruder attacks by physically separating the communicating networks. In recent years, the patented Lock-Keeper system has been developed and improved to be more mature, dependable and applicable.
