With the rapid development of the Internet, there is a huge amount of data and information, and human society has gradually stepped into the era of big data. The big data era can bring people more real-time information about the development of the times, so that human thought can keep pace with the development of the times, and bring convenience to the exchange and communication between people. Even though the Internet technology in the era of big data has many advantages of its own, there are still a lot of network information security risks in the application process, which will lead to the information data is not true, and at the same time, it will have a negative impact on the timeliness of the information people use. Therefore, in the era of big data, we should pay more attention to the security of network information, relying on scientific and reasonable network information security management program to prevent network security problems, so as to accelerate the pace of China's modern information construction.

Security issues in the network in the era of big data

As the network has a strong openness, it can realize the communication and interaction across space and time, but at the same time, it is also easy to suffer from the invasion of different spaces and themes and attacks, which will lead to the leakage of data and information, resulting in a serious network security problems. Secondly, there is human error, because Internet users do not have a clear sense of security in the process of surfing the Internet, it is easy to download and click on dangerous software and websites, resulting in cell phones or computers suffered from viruses, and then lost private information, account information and so on. Once again, there is the problem of network hacking, hackers can destroy the user's network system by stealing network information or network keys, so that the user's private information is threatened, and may even cause the entire network system to malfunction or paralyze.

Protection measures for network security in the era of big data

1, the use of secure antivirus software and strengthen the supervision work

The computer not only needs to use appropriate firewall technology, to create a good network operation atmosphere, and also need to install antivirus software. In this way, you can check the data in the computer in detail, comprehensively improve the security of the computer, to prevent the virus invasion of the security risks. On the other hand, enterprises also need to do a good job of computer network security supervision, centralized management of existing accounts, strengthen their own security management awareness.

2, strengthen the network security awareness

The relevant staff should be in-depth understanding of the computer operating procedures and precautions, pay attention to the possible dangers, do not download, do not click on the link of the unknown source, to enhance their own network security awareness. In addition, it is necessary to strengthen the study, expand the knowledge, enhance the ability to prevent, and develop a correct habit of using the computer.

3, strengthen the network control ability

The main reason for the impact of computer security is that the staff do not pay enough attention to network maintenance, just computer security is affected. Network managers should strengthen the maintenance of information security, build out the corresponding network control mechanism. Through the relevant anti-control software on the network virus, hacker invasion behavior monitoring, while the system is also able to analyze and control the network activities of the user to participate in the timely pop-up security pop-up windows, in order to avoid the occurrence of network security issues.

4, strengthen network security management

Strengthen network security management, focus on the application of technology, to provide basic protection for network security. That is, through the network maintenance, regularly check the network security issues, enhance the management of network security and data security, to protect the normal operation of the information network. In this process, network managers need to regularly check the system vulnerability, timely update the antivirus software virus database.
