What is DLP?

DLP stands for "Data Loss Prevention." It is a security technology that is designed to prevent the unauthorized disclosure of sensitive or confidential data. DLP systems are typically used to protect data that is stored on computer systems or transmitted over networks.

DLP systems work by identifying sensitive data, such as credit card numbers, social security numbers, and proprietary business information, and then monitoring and controlling access to that data. They can be configured to block the transmission of sensitive data over networks, prevent the saving of sensitive data to unauthorized locations, and alert administrators when sensitive data is accessed or transmitted in an unauthorized manner.

DLP systems can be implemented in a variety of ways, including as standalone software applications, as part of a larger security platform, or as a service provided by a third party. They are often used in conjunction with other security measures, such as firewalls, intrusion detection systems, and access controls, to provide an additional layer of protection for an organization's data.

DLP systems have many limitations and may not be suitable for all organizations. Some common failings of DLP include:

• Complexity: DLP systems are complex to implement and manage, and they require specialized knowledge and expertise to set up and maintain.
• False positives: DLP systems generate a high number of false positives, meaning that they block or alert on legitimate data transfers that are not actually a security threat. This leads to frustration and inconvenience for users, and it also results in a lack of trust in the system.
• Evasion: DLP systems are circumvented by users who are determined to bypass them, either intentionally or unintentionally. For example, users may use unsecured channels, such as personal email accounts, to transmit sensitive data, or they may use encryption or other techniques to evade detection.
• Cost: DLP systems are expensive to purchase and maintain, and they require significant resources to implement and manage. This is a barrier for some organizations, particularly smaller ones with limited budgets.
