What is data Security , whatever information was collected. it was saved. There were some people who stole it. In ancient times was very difficult .for example, in ancient times, the message one of the important means of communication was sending of messages through the birds. So the enemy would shoot down the birds and read the information or whatever the was.
Similarly as time passed and communication progressed .similarly in modern times, some companies protected their data in such a way that no one could gain access to or from the data without their permission. This type of privacy is called data privacy or data security .any person tries to gain access to or from the data then it is immediately acted upon. In the simple words, it can be said that protecting the data is called data security.
What is data Security:
Encryption is a technique that is used to protect data. It uses different types of models. Though these modles, they are charged in such a way that only the parties who have ability to read it .only they can read it .no one else can access that data. These types of strategy are called data encryption.
Erasing of Data:
A strategy that erases some errors from the saved data after the saving data is called data eraser .there are some errors in the data which corruption the data from within. Such errors erasing is called data eraser.
Masking of Data:
A Strategy in which the data is copied. But the data is sensitively distributed .the unique data or data is checked. Data masking used this purpose.
Resilience of Data:
What is data security in which a system or network is used in an emergency. For example, when data may be destroyed by natural disasters such as storms, heavy rains or strong winds, adequate data backup is required in such situations. Data is stored and sued later. Such data is called data resilience.
What is data Security
- Protects data security data from unauthorized persons and prevents them from being stolen.
- Data security helps protect data in large operations.
- Data security also helps protect government legal secrets.
Disadvantages of data security
- The most important problem with data security is that there are subtle costs that that are incurred at the outset
- The second biggest threat to data security is that companies invent new security methods that required a person to be updating all the time .Due to which some mistakes are made by the person. Due to which the person does not stay alert. And he cannot get information and because of which he is deprived of security.
- A third risk of data security is that it uses a variety of tools that require different systems to manage and therefore are time consuming and therefore time-consuming.
