Dynamics and Control Strategies for SLBRS Model of Computer Viruses Based on Complex Networks

Figure 9

(a) In the initial stage of virus propagation, the network has only a few L and B nodes. At this time, the network virus spreads rapidly and the security of the system decreases rapidly; (b) the figure shows the trend of the four types of nodes in the network at virus propagation time 73. It can be seen that the number of L nodes, B nodes, and R nodes increases rapidly over time and the number of S nodes decreases rapidly.
