In the era of information, data security, especially computer data security has been placed in an important position. But what is computer data security? In fact, computer data security has two meanings. The first meaning is data security itself. It mainly refers to the confidentiality, integrity and availability of computer data security. The second meaning is the security of computer data protection. It mainly refers to the protection of computer data by using modern information storage methods, such as disk array and data backup.
If users would like to protect computer data effectively, they have to know the basic features and threats of computer data security in advance. In view of this, we will introduce the basic features and threats of computer data security respectively.
- Confidentiality: confidentiality, also called secrecy, refers that the individual data or group data shouldn’t be obtained by irrelevant people. In computer, much software, such as mail software and web browser is equipped with relevant settings of confidentiality, so that users’ personal data can be protected.
- Integrity: as one of the basic features of data security, integrity refers that in the transmission and storage process of data, data will not suffer from unauthorized tampering or can be discovered immediately after tampering. In fact, integrity is often confused with confidentiality in the field of information security.
- Availability: data availability is actually a user-centered design concept. Availability should focus on the design of products in order to meet users’ habits and requirements.
Threats As a matter of fact, there are a lot of computer data security threats, so we will list some common threats here. 1. Hard drive damage: the damage of a computer hard drive means the loss of computer data. The operating loss of equipment, failure of storage media, operating environment and man-made destruction can all have a great impact on computer hard drive. 2. Improper operation: due to improper operations, users may delete important system files or modify the parameters which will affect system operating by accident. 3. Hackers: experienced hackers are able to invade users’ computer remotely and easily over the network. Many reasons can lead to the appearance of this phenomenon: system vulnerabilities, lack of management, and so on. 4. Computer viruses: the destruction of computer system caused by computer virus infection will bring huge losses to users. Under the network environment, computer viruses are provided with strong replication capacity, strong infection capacity and fast transmission speed. 5. Data interception: users’ computer data can be stolen by malicious people through various methods. 6. Power failure: the failure of power supply will make a momentary overloaded electrical power damage the data on computer hard drive or other storage devices. 7. Magnetic interference: magnetic interference means the contact of important computer data with magnetic substance and this will definitely lead to computer data damage.
After reading above content, all users will have a clear understanding of the basic features and threats of computer data security.
