• The development of information transmission has greatly accelerated the progress of society, and along with this, the security of information brings hidden threats to individual in the network. In this paper, a novel security defense trade-off strategy between information transmission and information security is proposed based on network performance gain function. First, the network performance gain function is defined on network average information intensity and network security index, and dedicated to make a trade-off between information transmission and information security of the network. Based on the gain function, node isolated strategies are provided, and corresponding algorithms named maximum degree isolation algorithm (MDIA) and maximum performance gain isolation algorithm (MPDIA) are devised respectively to isolate network node and improve network security. The results in simulation demonstrate that MDIA can quickly improve network security performance and MPDIA can acquire the larger gain within network robustness.
