Analysis of Information Security in Communication Networks Based on an Improved Bayesian Network

With the objective of enhancing the information security of traditional communication networks, an information security system based on an improved Bayesian network model was designed within the context of big data. Firstly, the hardware design of the communication network information security system was carried out. Meanwhile, an improved Bayesian network model was constructed by refining the traditional Bayesian network algorithm, and the corresponding algorithm flow was determined. Secondly, utilizing the improved Bayesian network model as a tool, security simulation experiments and error analysis on data were conducted. Finally, the simulation experiments demonstrated that the data processing technology based on the improved Bayesian algorithm enhanced the stability of network transmission, thereby ensuring the security of communication networks in the big data environment.
