What is data encryption?

Terms of data encryption include:

Plaintext, that is, original or unencrypted data. It is encrypted by the encryption algorithm, and the input information of the encryption algorithm is plaintext and key; Ciphertext, the format after plaintext encryption, is the output information of the encryption algorithm. The encryption algorithm is public, while the key is not public. The ciphertext shall not be understood by users without key, and shall be used for data storage and transmission; Key is a string composed of numbers, letters or special symbols, which is used to control the process of data encryption and decryption; Encryption, the process of converting plaintext into ciphertext; Encryption algorithm, the transformation method used for encryption; Decryption, the process of transforming the ciphertext inversely to the encryption to obtain the plaintext; Decryption algorithm, the transformation method used for decryption. Encryption technology is a technology to prevent information leakage. Its core technology is cryptography. Cryptography is a subject that studies cryptographic system or communication security. It is divided into cryptography and cryptanalysis; Any encryption system is composed of plaintext, ciphertext, algorithm and key. The sender encrypts the data with the encryption key and sends it out through the encryption device or encryption algorithm. After receiving the ciphertext, the receiver decrypts the ciphertext with the decryption key and restores it to plaintext. In the process of transmission, even if the ciphertext is stolen and obtained by illegal elements, only the unrecognized ciphertext is obtained, which plays the role of data confidentiality.

Why encrypt data?

"Data is the core asset in the information system. The loss, destruction or leakage of data may bring you incalculable losses. Encrypting sensitive data is one of the core means of data security protection. There are two types of data, one is unstructured data, such as documents and pictures, and the other is structured data, such as data in the database. Both forms of data are very important and need to be encrypted Protection. Structured data usually carries very concentrated and valuable information, so it is particularly important to encrypt and protect it.

What impact will data disclosure have on enterprises / individuals?

1. Damage to corporate public reputation

When an enterprise has data leakage, the public will have a sense of mistrust towards the enterprise, which will affect the public's choice. Therefore, the data leakage accident may cause the enterprise to lose a number of customers, including potential customers.After the disclosure of Yahoo email, a large number of users abandoned it, and Yahoo, which is negotiating the acquisition, was even difficult to sell for a time.

2. Damage to the economic interests of enterprises

On the one hand, data itself is a part of enterprise property. When data is leaked, this part of data assets is equivalent to handing over to others, which will threaten the competitiveness of enterprises, indirectly increase costs and reduce benefits.On the other hand, the loss of reputation will lead to the decline of enterprise stock price and the loss of users, which will have a direct impact on the economic interests of enterprises.At the end of last year, when the user data of qudian was leaked, the share price fell continuously, and even fell 30% at the opening.

3. Facing legal charges such as litigation

Once the data is leaked, there will be victims. The victims may be the data source itself, the downstream customers of the enterprise or other partners affected by the data leakageAfter the disclosure of 143 million users of Equifax, a US credit giant, faces a class action lawsuit in the federal court of Portland, with a compensation amount of up to $70 billion.

4. Internal disharmony factors

Some data leaks are caused by hacker attacks, while others are caused by poor internal management. The latter is more likely to make employees distrust the enterprise, and then affect the overall unity of the enterprise.The British supermarket Morrisons, one of the world's top 500 companies, once had a leak accident - the salary details, addresses and bank accounts of 100000 employees were stolen, leaked and sold by internal auditors. Not only the auditors were jailed, but Morrisons was collectively sued by more than 5000 employees, demanding that the enterprise be responsible and compensate for this.

5. Cause high-level shock

There must be various internal problems behind a data leak. When an enterprise has a serious data leak, senior executives usually take responsibility for it or even step down. After the e-mail scandal was exposed, the CEO of Miss America left immediately; After Uber exposed 100000 hacker sealing fees, the chief security officer was dismissed.

What are the functions of safe disk server?

Manage virtual disk image files:

1. Create:

Create a suffix of The virtual disk image file of FVD can be configured according to its actual use

image file: create storage (hard disk) address and file name
virtual disk size: the default is 8192mb. You can enter data according to your own usage
sector size: 512 bytes by default. 1024 / 2048 / 4096 data can be selected for filling according to the usage
format required: when creating an image file, format the disk
allocate all required disk space immediately
delete duplicate data in the image: delete duplicate data in the image
password of image file: image file encryption
confirm password: confirm the password of the image file again
create: click the Create button to create the above configuration data
cancel: return to the main UI

2 mount:

Mount Data settings are made for files with FVD suffix. The figure below shows the function area of mounting image files

backup point: the time when the virtual disk image was created
select the attached drive letter: in principle, all drive letters between a and Z can be selected
