While the development of the enterprise data security is effectively ensured, we should pay attention to the transfer of the environmental data security, and now most of the security encryption products in the market outside the enterprise environment data security protection is insufficient, resulting in software development knowledge of the personnel can easily be cracked, access to the secret data. From the perspective of security analysis, the external environment of the security problems related to data is divided into two, one is encrypted in the environment to export, one is to encrypt the storage in the external environment, each solution will be the security of the encryption products have high requirements, to have a complete encryption method, secure file encryption logic, In a word, it is not possible to create a dense situation in the event of a secret document being circulated. The following is a detailed description of these two implementation scenarios:

Encrypt confidential data from the database side and export the operation
Through the database encryption and then export its purpose is mainly to solve the problem of the application of confidential data in the outside, of course, the export file can be plaintext or ciphertext, which is based on the actual situation, but in the enterprise's encrypted security stream, the secret data outside the encryption environment must be transferred and stored in ciphertext, so as to ensure its security in the data itself , the enterprise business process often use to the secret enterprise data, so safe and stable offline data is very important. For the export of security data, for different enterprises have different solutions, some enterprises just to ensure the security of offline data, so through encryption to export into ciphertext, and then import it; some enterprises export data to independent intellectual property rights, so after the export of encrypted files have the number of open times limit, The other side to view the encrypted data reached a certain amount will automatically close, no longer view, fully protect the intellectual property of the enterprise.
Copy and transfer confidential data via Enterprise encryption USB drive
This way in the enterprise application is more extensive, the use of encrypted USB flash drive can be used to solve some of the problems of temporary applications in the enterprise. In general, the encryption U disk is mainly used in enterprises in the work of the outside or work at home Temporary security applications of encrypted files, mainly is the convenience of plug-in. Encryption USB flash drive can be bound with the enterprise's internal security network, it is stipulated that only the USB flash drive to reach the condition can read and copy the data, this is the point-to-point safe flow, although the data is already in the enterprise encryption environment, but the data will still exist in encrypted form, only if the encryption permission allows the data to be opened.
Regardless of the way to protect the encrypted data outside the encryption environment, only one is to ensure the security of the secret data, from the hardware level or software layer to encrypt the security operation of the data can achieve this goal, but most importantly, the core of data security is the security of people's cognition, enterprises should have this security awareness, Continuously to the internal staff to promote the importance of data security for enterprise development, so as to fundamentally solve the enterprise development of data security issues.
