Seven weapons to ensure data security

With the development of the information process, various information technologies and systems are widely used, and the number of data increases exponentially. At present, the focus of information security is no longer limited to the security of the system itself, instead, we should pay more attention to data security. Data security is not a new topic. From the early prevention of DDOS attacks, Trojans, viruses, and worms, from the use of firewalls, intrusion detection devices, gateways, and other hardware devices to the widespread use of encryption software, the entire informatization process is accompanied by data security issues. Today, with a high level of information technology, what technical means can be used to prevent data loss? After a lot of market research and research, the author provides the following seven weapons to ensure your data security.

Weapon 1: transparent encryption software

The encryption software mentioned here is not a free personal-level encryption software that can be freely downloaded on the Internet. We can download encryption software such as file folder encryption super master and encryption King from various software download websites. These software are only "pseudo encryption" and can be easily cracked by cainiao-level computer users, in addition, files are often damaged and cannot be recovered, which is very insecure.

The R & D department, design department, and other core departments of enterprise users generate a large number of source code, graphic design drawings, circuit design drawings, 3D images, or audio and video files every day, these files need to be encrypted during the process of generation, use, storage and transfer. This requires enterprise-level "transparent encryption software ". This kind of software is quite mature in China, represented by Smartsec software.

Smartsec is a software product that enforces data encryption/Decryption for internal information leaks. The system adopts the "Driver-level transparent dynamic encryption and decryption technology" Without Changing users' usage habits, computer file formats and applications ", performs real-time, forced, and transparent encryption and decryption on specified types of files. In normal use, files in the computer memory are stored in protected plaintext, but the data stored on the hard disk is encrypted. If you do not have a valid identity, access permission, or the correct security channel, all encrypted files are saved in the ciphertext state. All data obtained through illegal channels are displayed as garbled files.

Second weapon: Document permission management software

For personal users, you can use Windows Rights Management Services (RMS) and Information Rights Management (DRM) in the Office version) to prevent users from abusing email messages and Office documents (mainly Word, Excel, and PowerPoint) you send to them by means of forwarding and copying ). Data Rights Management is generally used by foreign enterprises. For enterprise users, this type of permission management is quite amateur, and the biggest problem is that this type of permission management does not encrypt the data itself. Using this type of permission management does not achieve real fine-grained permission division. It is a very extensive management method, and data leakage is inevitable.

For enterprise users, a professional permission management system is required for document permission management. This is an electronic document security sharing management system that is controllable and authorized to enterprise users. The system uses the "driving-level transparent dynamic encryption and decryption technology" and real-time permission revocation technology to encrypt and protect general electronic documents, and can set detailed permission for Encrypted documents, make sure that the confidential information is operated within the specified time in the authorized application environment. Different users have different permissions for the same document ". Through security protection at the document content level, the Internal Security sharing mechanism of classified confidential information and divided permissions is realized.

Third weapon: document release management system

For enterprises that often need to send documents to partners or business travelers, if they send documents to external organizations, they will be left alone, which will inevitably lead to the risk of major confidential leaks. To prevent the risk of disclosure after the document is published, the document release management system is currently the most effective method,
At present, there are many products for this document release management software. Yisaitong's document release management system is an outstanding one. The yisaitong document Outsourcing Management System is an outsourcing security management solution designed for customers' important information or core data external security requirements. When the customer wants to send important documents out to the customer's travel staff, partners or customers, the application document outsourcers package and generate the outsourcers. When an external file is opened, you must pass user identity authentication before you can read the file. At the same time, the outgoing file can limit the recipient's reading times, usage time, and other fine-grained permissions, effectively preventing the spread of important customer information.

Fourth weapon: full disk encryption system

On a business trip or on a trip, our laptop is lost, or the laptop is stolen during transportation, at home or in a parked car, or the laptop is being repaired ...... In these cases, how do I protect the data security on my laptop?
The disk's full-disk encryption system dynamically encrypts and decrypts data on disks or partitions. When the computer is shut down, the data stored in the hard disk is encrypted. No one enters the key and others cannot obtain the encrypted data on the hard disk, this prevents laptop data leakage. This system is quite mature and widely used at home and abroad.
