Abstract
With the rapid development of information technology, network attacks are increasingly complex and changeable, and the traditional network security protection means are difficult to deal with advanced persistent threats. As an important carrier of internal information interaction in enterprises, the security of LAN has attracted much attention. This study focuses on the application of network intrusion tolerance technology in LAN, aiming to build an adaptive network security system to ensure that the basic service functions can be maintained when the network is attacked. By analyzing the existing intrusion tolerance mechanism, the technical fr amework based on redundancy design and fault-tolerant algorithm is proposed, and then the distributed node deployment and dynamic routing adjustment strategy is used to improve the robustness of the system. The experimental results show that in simulating multiple attack scenarios, the technical scheme can effectively reduce the attack success rate and maintain the network connectivity and data integrity, which has significant advantages over the traditional protection measures.
