Research on the Application Risk of Computer Network Security Technology

In the new era, computer network security issues have attracted more and more attention. How to use the latest technology to strengthen the network operating environment and prevent data information leakage has become the focus of network security management. This paper studies the computer network security technology in the era of big data. First, it is proposed that network data has the characteristics of high security factor, fast computing efficiency, and resource sharing. Secondly, it analyzes the security risks of computer networks to clarify the existing virus intrusion risks and network security. Vulnerabilities and operating system risks are different types. Finally, it focuses on the realization path of computer network security technology, and introduces the application points of firewall technology, data encryption technology and PKI technology.
