Updated on:

Have you ever experienced the crippling feeling of losing your data? That moment when you realize that all of your valuable data and information is gone is enough to make anyone feel helpless. I’ve seen it happen time and time again. I’m here to share some important information with you about Data Loss Prevention, specifically the three types you should be aware of.

Data Loss Prevention, or DLP, is a critical component of any organization’s cybersecurity strategy. It refers to the practices and technologies used to prevent sensitive data from being exposed, stolen, or unintentionally leaked. There are three types of data loss prevention that you need to understand: data at rest, data in motion, and data in use.

Let’s take a closer look at each type to understand their importance in protecting your organization’s data.

What are the three types of DLP?

Preventing data loss is crucial for businesses as sensitive information can often fall into the wrong hands, leading to data breaches and potential legal and financial repercussions. To combat this issue, there are three primary types of DLP (Data Loss Prevention) methods that organizations can implement: endpoint DLP, network DLP, and cloud DLP.

  • Endpoint DLP: This type of DLP monitors data in transit from a user’s device to other devices or networks. Endpoint DLP software is installed on the device to monitor and restrict data access. It can also protect sensitive data when it is stored locally on the device’s hard drive.
  • Network DLP: This DLP method monitors data that flows through networks, such as email, instant messaging, and web traffic. Network DLP scans packets of data and filters out any sensitive information that is not authorized to leave the organization. It can also identify and flag any unusual data transfer activity.
  • Cloud DLP: With the increasing use of cloud storage, it is important to have DLP measures in place to safeguard sensitive data. Cloud DLP monitors and controls the flow of data to and from cloud-based services. It can identify and block unauthorized access to sensitive information stored on cloud servers.
  • Implementing multiple layers of DLP can provide higher levels of security and reduce the risk of data breaches. While these prevention methods cannot guarantee complete protection, they are essential in safeguarding sensitive information.


    ???? Pro Tips:

    1. Understand the different types of DLP – Network DLP, Endpoint DLP, and Storage DLP. This will help you determine the most effective DLP solution for your organization’s needs.
    2. Tailor your DLP strategy to your organization’s unique needs – DLP solutions should be customized to your organization’s specific security needs and policies, as well as the types of data you handle.
    3. Monitor and classify your data – Regularly monitor your data to understand where it resides, how it’s being used, and who has access to it. Classify your data into categories, such as confidential, sensitive, or public, to better manage and protect it.
    4. Educate your employees – Employees play a key role in ensuring the success of a DLP strategy. Provide training and awareness programs to educate them on data security best practices, including the importance of data classification and handling procedures.
    5. Implement robust policies and procedures – Develop comprehensive policies and procedures for data handling, including data encryption, access controls, and incident response plans. Regularly review and update these policies to stay current with new threats and vulnerabilities.

    What are the Three Types of DLP?

    Data loss prevention (DLP) is a crucial aspect of cybersecurity. It is the process of protecting sensitive information from being accessed or stolen by unauthorized individuals. There are three types of DLP: endpoint DLP, network DLP, and cloud DLP.

    Endpoint DLP

    Endpoint DLP aims to prevent data loss from devices such as laptops, smartphones, and tablets. It involves keeping sensitive data from being copied or transferred to unsecure devices or networks. Endpoint DLP has become increasingly important as more people work remotely and rely on portable devices to access sensitive company data.

    Endpoint DLP strategies include:

    • Encryption of sensitive data on devices
    • Remote-wiping of lost or stolen devices
    • Blocking the copying of confidential data onto external devices
    • Monitoring of data transfers to external networks

    Network DLP

    Data can be accessed and transferred over many types of networks, including the internet, Intranet, and LANs. Network DLP focuses on preventing unauthorized access to sensitive data as it moves across these networks. Network DLP solutions can monitor the flow of data across the network, identify and prevent data breaches, and enable the use of encryption to secure data in transit.

    Network DLP strategies include:

    • Network traffic monitoring
    • Detection of sensitive data in transit
    • Blocking of unauthorized access to sensitive data
    • Encrypting data in transit

    Cloud DLP

    With the increasing use of cloud-based storage and computing, cloud DLP has become a crucial aspect of data protection strategy. Cloud DLP aims to prevent unauthorized access to sensitive data stored in cloud-based services. It involves controlling access to data stored in the cloud, monitoring data usage, and encrypting data in transit to and from cloud-based services.

    Cloud DLP strategies include:

    • Encryption of data stored in cloud-based services
    • Controlled access and authorization to cloud-based services
    • Monitoring of cloud-based services for unauthorized access to sensitive data
    • Enforcing compliance with industry or government regulations

    Understanding Endpoint DLP

    Endpoint DLP is focused on the security of the devices from which data is accessed. These could be laptops, smartphones, tablets, or other personal devices that are used to access sensitive data. Endpoint DLP strategies aim to prevent data from being copied or transferred to unauthorized external devices or networks. Endpoint DLP also includes policies and procedures regarding the secure use of devices that have access to sensitive data.

    Understanding Network DLP

    Network DLP is concerned with the security of data in transit across networks. It involves monitoring network traffic for unauthorized access, identifying sensitive data in transit, and preventing data breaches. Network DLP also includes strategies for encrypting data in transit to protect it from unauthorized access.

    Understanding Cloud DLP

    Cloud DLP is becoming increasingly important as more organizations move their data storage and computing to cloud-based services such as Microsoft Azure, Google Cloud, or Amazon Web Services. Cloud DLP involves protecting sensitive data through encryption, access control, and monitoring. This includes controlling who has access to data stored in cloud-based services and monitoring how data is used.

    How Endpoint DLP Works

    Endpoint DLP works by monitoring all activity on devices that have access to sensitive data. Policies can be set up to control how data is stored, copied, or transferred, and encryption can be used to protect sensitive data on devices. Endpoint DLP solutions can also enable remote-wiping of lost or stolen devices to prevent data from being accessed by unauthorized individuals.

    How Network DLP Works

    Network DLP works by monitoring network traffic for unauthorized access to data and identifying sensitive data in transit. Policies and procedures can be set up to block unauthorized access to sensitive data or to encrypt data in transit to protect it from unauthorized access. Network DLP solutions can also enable the blocking of sensitive data from being sent outside of the organization’s network, preventing data breaches.

    In conclusion, there are three types of DLP: endpoint DLP, network DLP, and cloud DLP. Each type of DLP has different strategies and solutions to protect sensitive data from being accessed or stolen by unauthorized individuals. By implementing DLP solutions, organizations can better protect their sensitive data and reduce the risk of data breaches.
