Design of network terminal data security protection system in cloud computing environment

In the cloud computing environment, network terminal data has the characteristics of large quantity and real-time changes. In order to ensure the security of network terminal data, a network terminal data security protection system is designed in the cloud computing environment. The system includes hardware modules such as intrusion detection, vulnerability scanning, and cloud security management, which can ensure that only authorized users can access data and achieve recognition and prevention of malicious behavior. On the basis of hardware design, a hybrid encryption algorithm is adopted to encrypt network terminal data, further improving system performance and security, and protecting data security in cloud computing environments. The experimental test results show that the system has a low false alarm rate, a high malicious attack blocking rate, and a malicious attack detection rate, which can effectively ensure the security of network terminal data.
