From the environment and security status quo faced by big data, although big data is unstructured or more difficult to screen and analyze, it does not mean that big data is necessarily more secure. If all big data repositories are useful, every piece of information cannot be maintained equally. The more data a big data platform collects, the more difficult the task and challenge of keeping this data granular becomes.
How to ensure big data security
1. Big data collection security
Through data security management, data type and security level marking, the corresponding functions are embedded in the backend data management system or seamlessly connected with it to ensure network security accountability, security level protection, data classification and classification management and other types of data security. The system is implemented.
2. Big data storage and transmission security
The confidentiality and integrity of data are guaranteed through cryptographic technology. In the data transmission process, encrypted transmission links between different security domains are established, and the data can also be directly encrypted and transmitted in ciphertext to ensure the security of the transmission process. During the data storage process, data encryption, disk encryption, HDFS encryption and other technologies can be used to ensure storage security.
3. Big data sharing and destruction
When sharing data, in addition to following relevant management systems, it should also be combined with the security domain to effectively manage data sharing behavior while meeting business needs. During the data destruction process, software or physical methods can be used to ensure that the data stored on the disk is permanently deleted and cannot be recovered.
The development and progress of big data has brought great convenience to people's lives. However, as more and more people begin to pay attention to privacy, the security issues of big data have gradually attracted attention. People are very worried that their data will be obtained by people with bad intentions, which will cause them all kinds of troubles.
