Application of Logic Gap Based on Linux Bridge
Wen Wang · Journal of Henan University of Science & Technology · 2008
The gap is one of defense method on security.In the tradition way,the gap is realized by hardware,and the control is complex.Based on Linux bridge frame,a new logic gap based bridge(LGBB)method is proposed,which can capture packet in link layer,realize unidirectional data stream by logical switch,and filter data in application layer.The logical gap fulfills most function of traditional physical gap.
