Why Is Data Loss Prevention Important?

For both individuals and organizations, data protection is important and vital.

Loss of data can be disastrous. It also affects privacy and security. If some important data are stolen and falls into the wrong hands like cybercriminals, they might use that data to blackmail money or conduct more breaches.

Especially for enterprises, the loss of sensitive and crucial data can affect the reputation and development of the enterprise, even cause huge financial loss and lead to lawsuits. They should put much more importance on data protection.

Therefore, cyber security experts must find ways to block attacks and breaches. And this comes down to robust data loss prevention (DLP).

What Is Data Loss Prevention (DLP)?

Data loss prevention (DLP) technology aims to identify, monitor and protect your data, both in storage or in motion through network, from misuse/theft/ransomware/leakage.

DLP is a technique to make sure that end users don’t send sensitive or critical information outside the corporate network, so as to prevent sensitive and important data from being lost, misused or accessed by unauthorized people.

Data Loss Prevention Software:

DLP also refers to data loss prevention software products that are used to help network administrators detect, monitor and block potential sensitive data breaches in use, in motion and in storage.

How Does Data Loss Prevention (DLP) Software Work?

DLP software uses business rules to classify sensitive, confidential and critical data, and identify the violations of data security policies that are framed by organizations. DLP techniques are used to enforce the data security policies like HIPAA, GDPR, or PCI-DSS.

Once the data loss prevention (DLP) software finds some violations of those policies, it will conduct remediation with alerts and try some other actions to prevent users from accidentally or maliciously sharing sensitive and critical data. DLP software will often use AI to watch for suspicious behavior, in a similar way for antivirus software, to watch and stop potential problems before causing damage or loss to data.

For instance, if an employee in a company tries to send an email with sensitive data outside the corporate domain network or upload a file to cloud storage, this action would be blocked with DLP.

If you use data loss prevention software to protect your important sensitive data, DLP can tag those sensitive data and monitor activities and events around that data.

Data Loss Prevention Categories:

The data loss prevention (DLP) technique can be divided into three levels: standard security measures, advanced security measures, designated DLP systems with access control and encryption.

Data Loss Prevention Types:

DLP technology can be used to protect the security of various kinds of data:

  • Network data (data in motion) – monitor and analyze sensitive data that is being transmitted over the network.
  • Endpoint data (data in use) – monitor and control information flow between groups on internal end-user workstations or servers.
  • Data identification – organizations use a DLP technology to identify what to look for.
  • Data leak detection – investigate the source of the data leak.
  • Data at rest – refer to the old archiver information. Businesses can use access control, data encryption and data retention policies.
  • Data in use – data that is currently interacting with.
  • Data in motion – data that is transferred through a network to an endpoint.

Data Loss Prevention and Data Leak Prevention

Data loss and data leak are similar, and are often used interchangeably. When the lost data, containing confidential and sensitive information, is acquired by unauthorized third-parties, it becomes a data leak.

However, a data leakage may not cause the data to lose from the original owner.

Data loss can not only mean data leakage, but also mean loss of data because of mistakenly deletion, malware/virus infection, system crash, and other situations which might cause data loss of your device.

What Are the Best Data Loss Prevention Tools?

As for data loss prevention, to ensure the data is securely stored in the device should come in the first place. The next action is to make sure that only correct users or groups have the right permissions for the right data. The third advanced measure is to use DLP software to monitor and enforce the data security so as to prevent data from leaking or being damaged/lost.

There are some data loss prevention software products out there in market to help you prevent data loss/leak.
