While the internal data security of the development enterprise is effectively guaranteed, attention should be paid to the circulation of data security outside the environment. At present, most of the security encryption products on the market have insufficient data security protection outside the enterprise environment, resulting in personnel with software development knowledge. It can be easily cracked to obtain classified data. From the perspective of security, there are two solutions to the security problems involving data outside the environment, one is to encrypt and export in the encrypted environment, and the other is to encrypt the storage in the external environment. There are high requirements for the security of encryption products, complete encryption methods, and secure file encryption logic. All in all, it is not possible to cause secret-related situations when secret-related files are circulated outside. The following two implementation schemes are described in detail:

Encrypt confidential data through the database side and then export it

The purpose of re-exporting through database encryption is to solve the problem of external application of confidential data. Of course, the exported file can be plaintext or ciphertext, which depends on the actual situation. Confidential data must be circulated and stored in cipher text, so as to ensure the security of the data itself. In the course of business operations, confidential corporate data is often used, so secure and stable offline confidential data is very important. For the exported security data, there are different solutions for different enterprises. Some enterprises only want to ensure the security of offline data, so they can be exported into ciphertext through encryption, and then imported; some enterprises have independent intellectual property rights for the exported data. , so there is a limit on the number of times the encrypted file is opened after exporting. When the encrypted data is viewed by the other party, it will be automatically closed and can no longer be viewed, which fully protects the intellectual property rights of the enterprise.



Copying and transferring confidential data through enterprise encrypted U disk

This method is widely used in enterprises. The convenient and safe use of encrypted U disk can solve some temporary application problems in enterprises. Under normal circumstances, encrypted U disks are mainly used in the temporary security application of encrypted files when the internal staff of the enterprise work outside or at home, mainly because of the convenience of plug-and-get. The encrypted USB flash drive can be bound with the internal security network of the enterprise, and it is stipulated that only the USB flash drive that meets the conditions can read and copy data. This is a complete point-to-point secure flow. Although the data is outside the enterprise encryption environment, the data will still be stored. Existing in encrypted form, the data can only be opened if it is read with the permission of the encryption permission.



No matter what method is used to protect confidential data outside the encryption environment, the only purpose is to ensure the security of confidential data. Encrypting data at the hardware level or software level can achieve this purpose, but the most important thing is , The core of data security is the security of personnel cognition. Enterprises must have this security awareness and constantly publicize the importance of data security to corporate development to internal employees, so as to fundamentally solve the data security problem of corporate development.
