Applications of data masking
There is a myriad of applications of data masking, especially in information security. Some of them are:
- Auditing: In auditing, you need to keep track of and maintain the accuracy of all the data given by an organization or some other source. Naturally, it is important to keep the data safe and secure which can be achieved by data masking.
- Access Control: Making sure that only authorized personnel gets to access any sensitive data and modify them is known as access control. Data masking plays a vital role in access control as it can cover up for any mishaps that may indefinitely happen and prevent major damage.
- Cryptography: As discussed earlier in the techniques section, there is a technique called encryption. Encryption is a method used in cryptography to hide sensitive data. Hence, data masking is an important concept to know in order to pursue cryptography.
What is Data Masking?
Data masking is a very important concept to keep data safe from any breaches. Especially, for big organizations that contain heaps of sensitive data that can be easily compromised. Details like credit card information, phone numbers, house addresses are highly vulnerable information that must be protected. To understand data masking better we first need to know what computer networks are.
