Data Loss Prevention - Meaning, Types, Working, and Benefits

There is no organization that is immune to data security threats. However, when your IT environment becomes more complicated — for example, through the introduction of cloud technologies — implementing the data protection you require to secure your organization becomes even more difficult. Many businesses struggle to secure key information, such as intellectual property, personally identifiable information subject to numerous rules, and sensitive financial information.

Building a layered defensive strategy is the best way to help prevent data leaks and loss. You must limit your attack surface, actively monitor for unusual activity and insider threats that may result in data breaches, and develop an effective recovery strategy.

Data loss prevention (DLP) is an essential part of any effective strategy. In this blog post, you will know about data loss prevention, its working, types, and benefits.

What is Data Loss Prevention?

Data loss prevention practices are information security practices that are aimed to keep sensitive or vital information in the company network from being lost, stolen, or accessed by unauthorized individuals. Data loss prevention procedures help to reduce the risk of data leakage, loss, and data theft by ensuring that sensitive information is recognized and risk-appropriate measures are implemented with minimal impact on business activities.

DLP is a process, not a software package, and it is only one component of your overall data protection strategy.

If you’re just starting out with data loss prevention, keep in mind that data governance should come first. Effective data leak security involves understanding what vital data is stored and establishing policies and procedures for keeping, using, and relocating that data. For example, if your file server permissions are not correctly configured and checked on a regular basis, your DLP process can generate false alerts, which can result in costly incorrect responses, such as restricting lawful activity that is crucial to a critical business function.

How Does Data Loss Prevention (DLP) Work?

Three primary tasks are involved in data loss protection:

• Analyze and categorize the content: Monitoring your data, both on-premises and in the cloud, is a vital prerequisite for data loss protection. The best method is to search your data repositories with automated data discovery and data classification techniques and tag all essential, sensitive, or regulated material with digital signatures that show if it is, for example, a medical record, financial data, or intellectual property. As a result, you can use DLP to protect data based on its importance to the organization.
• Link to context: Enterprise data can be at rest, in motion, or in use, with each state including different data loss pathways. By evaluating the context of each action or event, data loss prevention solutions help to limit these risks.
• Compare with policy and act: This process is unique to DLP systems that use business rules, regulations, and conditions to detect inappropriate or malicious behavior, such as an attempt to download sensitive data onto portable media in violation of corporate guidelines. When a certain condition is fulfilled, the DLP policies indicate what action should be done, such as permitting or banning the activity, suspending the account, or notifying the event to the security administrator.

Types of Data Loss Prevention (DLP)

Data loss prevention software is classified into three types: network, endpoint, and cloud. All three provide the same results (data protection), but the techniques used differ from one to the next.

Network DLP 

As the name implies, DLP creates a safe perimeter around network data in motion. In contrast to endpoints, this solution monitors and manages data as it flows across the company’s network.

As an example, if a user tries to email sensitive information while on the company’s network, the network DLP security will perform one or more of many pre-programmed steps, such as data encryption, blocking, preventing, or auditing the email. It can also warn the administrator of attempted email transmission.

Network DLP solutions are helpful when a computer is connected to a network, but their protection does not extend to laptops and devices that are not connected to a network.

Endpoint DLP

Endpoint DLP does not operate on networks when data is in transit. Instead, it is placed on each individual device, which houses the network’s endpoints. Endpoint DLP security analyzes data as it goes to and rests in these endpoints, independent of their location or how they are connected to the network or internet. It can also identify when sensitive data is stored in files on devices that are not encrypted.

Endpoint DLP provides more complete protection than Network DLP, but it also necessitates more management. Endpoint DLP monitoring software must be installed on each device. When firms have remote employees, this might be difficult logistically. It is also necessary to consider the time and attention required to run and maintain an Endpoint DLP solution.

Cloud DLP

Cloud DLP is similar to Endpoint DLP in that it imposes DLP rules and regulations on specific cloud accounts. Like Network DLP, it does not create a perimeter around a standard on-premises network. It instead interfaces with cloud tools such as Office 365 and Google’s G Suite (and many others).

This provides your employees with the security and convenience of using cloud apps and cloud services without the risk of data breach or loss.

Benefits of Data Loss Prevention (DLP)

The following are the benefits of DLP:

• Legal compliance can be ensured by properly deploying DLP security. Legislations like HIPAA, CCPA, and GDPR need you to know where personal/patient data is and how it is transferred and handled, which this data loss prevention software can achieve.
• DLP also safeguards against personal data being copied, pasted, transferred, or printed mistakenly to other sections of the network and being used in unexpected ways.
• Data loss prevention software protects unauthorized use of all sensitive data by ensuring that no person or script may transfer sensitive data to the incorrect location. Such attempts will be disrupted or restricted.

Conclusion

To secure your important data from attacks and incidents, you need a multi-layered data loss prevention approach. There is no single enterprise DLP product that can handle all of your data security issues; DLP requires a complete procedure.
