Research on Efficient Construction Method of Large-scale Network Multi-granularity Nodes for Distributed Cyber Range
The increasing severity of cyber security threats has led to a growing interest in the use of network cyber range as a means of assessing risks,conducting defensive exercises in complex scenarios.A pressing issue is how to reasonably utilize the computational resources within network cyber range to efficiently construct target networks.This paper proposes a large-scale,multi-granularity node fusion method for dynamically building networks,which leverages the computational resources by coordinating the work of multiple granularity nodes and expand the network scale.Furthermore,the method improves the E-CCD algorithm to optimize the time complexity of the inter-node link addition,thus reducing time in network construction.Results have shown that the construction of large-scale networks with a node scale of 100 000 can be completed within 235 minutes,making it applicable to mainstream distributed and heterogeneous cyber range.
