What is Data Loss Prevention?
DLP Stands for Data Loss Prevention. Data Loss Prevention is a security risk strategy for critical data, known as data leak prevention, information loss prevention, and extrusion prevention. DLP is frequently used as a company’s overall data security strategy.

All About DLP
The term DLP refers to defending companies against both data loss and data leakage prevention. Data loss is an event in which critical data is lost to the organization, such as in a ransomware attack. Data loss prevention focuses on preventing the unauthorized transfer of data outside of organizational boundaries.
DLP is commonly used in businesses to:
- Keep personally identifiable information (PII) secure and adhere to all applicable regulations.
- It is critical that the organization safeguard its intellectual property.
- Obtain data visibility in large organizations.
- Secure mobile workforces and enforce security in Bring Your Own Device (BYOD) environments.
- Data protection on remote cloud systems
Aim of DLP
- DLP aims to prevent unauthorized access to sensitive information by utilizing a variety of software tools and data privacy policies. This is accomplished by classifying the various content types within a data object and implementing automated protection policies.
- Developing a DLP plan also allows a company to review and update its data storage and retention policies in order to maintain regulatory compliance.
Data Loss Prevention Methods
Network DLP includes a wide range of data security methods. Some of these examples are listed below:
-
Data Identification
DLP is only useful if you tell it what is sensitive and what is not. Rather than relying on humans, organizations should use automated data discovery and classification tools to ensure reliable and accurate data identification and classification.
-
Protecting Data In Motion
Internally, data is moved around a lot, and external breaches frequently rely on this to redirect data. DLP software can help ensure that data in transit does not end up somewhere it should not be present.
-
Protecting Data At Rest
This technique secures data when it is not in motion, such as when it is stored in databases, other apps, cloud folders, computers, mobile devices, and other storage devices.

Detection Of Data Leaks
Setting a baseline of normal activity is the first step in this technique,
followed by constantly searching for unusual behavior.
-
DLP Cloud
DLP solutions have evolved to manage and protect critical data
in Software as a service and Infrastructure as service applications.
Data Loss Prevention Solutions
-
Securing Data In Transit
edge of the network technology can analyze traffic to detect sensitive data sent in violation of security policies.
-
Endpoint Protection
endpoint-based agents can control data transfer between users, groups of users, and third parties. Some endpoint-based systems can detect and respond to attempted communications in real-time.
-
Data Security In Use
Some DLP systems can monitor and flag unauthorized activities that users may perform intentionally or unintentionally in their interactions with data.
Data Loss Prevention Software Tools
- Data loss prevention tools depend on two types of products: dedicated and integrated. Dedicated products are in-depth and complex dedicated hardware products. Integrated products are simpler, work with other security tools to enforce policies, and are less expensive than dedicated DLP tools.
- It’s unlikely that a single tool will meet all of an organization’s data loss prevention requirements. Many DLP vendors specialize in one area, whereas others offer suites of tools that work together. Businesses can either put together a collection of the finest tools or use an all-in-one suite.
The following are some of the top Webshops:
-

Data Loss Prevention Best Practices
Organizations can implement a DLP system in several ways, including the following:
-
Conduct an inventory and evaluation
Businesses cannot protect what they are unaware of. A complete inventory is required. Some DLP products, such as those from Malware Networks, Cisco, and McAfee, will perform a full network scan on their behalf.
-
Classification of data
Data should be classified. A data classification framework is required for both structured and unstructured data in organizations. Personal identifiable information (PII), financial data, regulatory data, and intellectual property are examples of such categories.
-
Implement policies for data handling and rehabilitation
After classifying the data, the next step is to develop policies for handling it. This is especially true for regulated data or areas with strict rules, such as Europe’s GDPR and California’s CCPA.
-
Automating Systems
The more DLP processes that are automated, the more widely they can be deployed across the organization. Manual DLP processes are inherently limited in scope and cannot scale to meet the needs of all but the most rudimentary IT environments.
-
Develop Metrics
Metrics such as the percentage of false positives, the number of incidents, and the mean time to incident response can be used to examine the performance of your DLP strategy.
-
Make use of algorithms
Some modern DLP solutions support simple statistical analysis and correlation rules with machine learning and behavioral analytics to detect abnormal user behavior.
-
Educating employees
Unintended implications far outnumber malicious intent. DLP depends heavily on employee awareness and acceptance of security policies and procedures.
Conclusion
Financial data, private information, credit card numbers, health records, and social security numbers are all instances of sensitive information under an organization’s control. They require a means to prevent their users from sharing sensitive data with people who should not have it in order to help protect it and reduce risk. This is why DLP is needed.
