How to protect data security

Large data has penetrated into every industry and business functional area, and gradually become an important factor in production, how to protect data security?

　　The first kind of weapon: transparent encryption software

This refers to the encryption software, not on the network can be free to download the type of personal data security encryption software. We can usually download a variety of software sites, such as folder encryption Super Master, encryption, such as the King encryption software, these software is only "pseudo-encryption", it is easy to be novice-level computer users to crack, and often occur files are destroyed can not be restored, very unsafe.

Enterprise users in the research and development departments, design departments and other core departments, daily production of a large number of source code, graphic design, circuit design, 3D graphics, or audio and video files, these files need to be in the production, use, storage and transfer process to encrypt the processing. This requires the use of enterprise-level transparent encryption software. This kind of software in the domestic already quite mature, take smartsec software and so on as the representative.

Smartsec is a software product that enforces encryption/decryption of data for internal information leaks. The system, without changing the user's usage, computer file format and application, adopts the "drive-level transparent dynamic encryption and decryption technology", which is used for real-time, mandatory and transparent encryption and decryption of the specified type of files. That is, in normal use, the files in the computer's memory are stored in protected plaintext, but the data stored on the hard disk is encrypted. If there is no legitimate use of identity, access rights, the correct security channel, all encrypted files are saved in ciphertext state. All the data obtained through illegal means are displayed in the form of garbled files, which protects the data security.

　　Second Weapon: Document Rights Management software

For individual-level users, you can take advantage of Windows Rights Management Services (Rights Management Service, abbreviation RMS), and Information Rights Management in the Office version (information Rights management,irm) To prevent users from abusing e-mail messages and Office documents (mainly word, Excel, PowerPoint) that you send to them using forwarding, copying, and so on. This is probably true of the DRM (Data Rights Management) used by foreign companies. For enterprise-level users, this privilege management is quite amateur, and the biggest problem is that this privilege management does not have high strength encryption on the data itself. The use of such rights management, do not really fine-grained permission division, is a very extensive management means, data security is difficult to protect.

For enterprise-level users, the rights management of the document needs to use a professional rights management system. Taking billion-match document Rights management system as an example, this is an electronic document security sharing management system which is controlled and authorized by enterprise users. The system uses "drive-level transparent dynamic encryption and decryption technology" and real-time privilege recovery technology, the common type of electronic documents encryption protection, and can be divided into the encryption of the document to set up the permissions, to ensure that confidential information in the authorized application environment, specified time, to carry out the specified operation, different users of the "same document" owned Different permissions ". Through the security of the content level of the document, the internal security sharing mechanism of confidential information is classified and divided.

　　Third Weapon: Document Outsourcing management System

For those enterprises that often need to send documents to partners or travel personnel, if the document is sent to an external unit, it will have the risk of causing a major secret leak. In order to prevent the risk of leaking after the document is sent out, it is the most effective data security to use the document outgoing management system.

At present, this kind of document outsourcing management software PRODUCT is more. Billion document outsourcing management system is a better one. Billion-way document outsourcing management system is an important information for customers or the core of external security requirements of the design of an external security management solutions. When a customer wants to send an important document out to a customer's business person, partner, or customer, the document outsourcing management program is packaged to generate the outgoing file issue. When the outgoing file is open, you need to authenticate with the user before you can read the file. At the same time, the outgoing file can limit the recipient's reading times and the use of time and other fine-grained permissions, thus effectively preventing the customer important information is illegally spread.
