What Is Data Loss Prevention (DLP)?

Whenever an organization tries to prevent its data from being passed over to unauthorized persons is quite called Data Loss Prevention. The data can be in use or personal to the owner and he/she does not want to share the data with anyone else from outside due to personal interest. But preventing it from passing it to other people is the hard part. Read below to find out how data leakage happens and how the Data Loss Prevention system works in order to prevent the misleading of Data.

What Does Data Loss Prevention Mean?

Data loss prevention, also known as Data Leakage prevention is the method of preventing the data to pass from one user to another. Because of how much today’s system is dependent upon cloud technology, it is necessary to improve the security of the cloud also.

Imagine a place where all our important data which is stored on the cloud goes into the wrong hands! All the personal information, address, credit card details, and many more can bring fate to cloud technology.

What Are The Types Of Data Leakage?

Accidental Breach

In these types of cases, sometimes the data that is crucial to the company is leaked unintentionally without anyone’s deed. This generally happens when an employee accidentally passes login credentials or any other important information without encryption to other servers. But this mistake can lead to a bigger security breach for the whole company.

Electronic Communication Medium

You all might have heard the term email fraud. That is one of the good examples of the electronic medium data breach. This includes not only the emails but different chat rooms, meetings, websites, or any other social platform where malicious links pass on. Cybercriminals can create and send these links and once opened by the employee or any other higher position person in the company, their data passes on to the intruders. These chatrooms or websites do have encryption and any third-party organization can steal the data by a man-in-the-middle attack.

Unsatisfied Employees

Also known as data exfiltration, this process includes data breaches that the company’s own employees create. The unhappy or unsatisfied with their job, these employees intentionally pass crucial organization information and market strategy with other companies or any outsider. The main reason is the person working is unsatisfied from his/her own company and other people from the outside company give money credits to that employee in exchange for insider information.

Physical Data breach

The employees or any other person at higher authority can create physical data breaches, who intentionally passes important data for their own benefits. There are many endless possibilities about how physical data breaches can happen. This could be any of the types like the person will upload crucial information on their cloud storage and share it to outside medium or make it publicly available for some time.

Divide and Profit Benefits

Generally, this type of data breach is less seen in the market but it still exists. A method that any inferior company follows for its survival in the market. To know the secrets of any successful company, that undistinguished company workers break through the network security and try to get the market strategy of a growing company. This can be done in many ways. One of the direct methods is using physical data breaches without the knowledge of any of the members of a growing company and stealing their data. Another method is to bribe and take information from any of the employees of the working company indirectly and use that information for personal benefits. 

How Costly Can Be A Data Breach?
