Fixing Data Leaks: The Next-Gen Data Loss Prevention (DLP) Solution

Data loss protection (DLP) is a critical component of any organization's security strategy. DLP refers to the set of technologies and practices that are designed to prevent sensitive or confidential data from being lost, stolen, or misused. In today's digital age, where cyber threats are increasing tremendously, data loss protection is more important than ever. Therefore, organizations need to roll out effective DLP solutions, to help them safeguard their sensitive data and maintain their competitive edge in the market.

Overview

A server exploits that occurred for a globally renowned data analytics and technology company led to a breach of credit reports from over 140 million people. It took several months to identify the severity of the breach, and in the end, it was a little too late! The company had to settle for a fine of $575 million.

Unfortunately, data leaks from endpoint devices, including employee laptops, tablets, or mobiles, do not often make headlines. However, losing invaluable IP, sensitive financial data, and confidential information from customers or future business plans can be equally devastating to the enterprises involved.

Data security is always a challenge! Advanced DLP (Data Loss Prevention) solutions are a necessity now more than ever, given the increasingly growing mobile and distributed workforce, allowing organizations to enforce effective data protection policies. Next-gen DLP services can provide flexible deployment options, such as cloud-based solutions, which are easier to manage and scale than traditional on-premises solutions. However, such proprietary solutions often need plug-ins to expensive SIEM (Security Information & Event Management) front ends to generate timely alerts, notifications, and insightful dashboards.

With the hybrid working models that the pandemic necessitated, it’s commonly seen that remote end-user laptops could be potential sources of data leaks. DLP agents can be installed in remote laptops, aiming to monitor and prevent data leaks.

Challenge: Limited Capabilities

The cloud-based DLP system lacks features of durability and extended data storage, reporting, dashboarding, and alerting. It has rigid capabilities concerning flexible data storage, data analysis, reporting, and alerting features. Cloud integration and secure data transfer are key aspects which can be achieved in the advanced solution.

Solution: Introducing DLP with SIEM-lite

The advanced DLP solutions can be built on an enterprise data lakehouse platform capable of ingesting, storing, and processing large volumes of DLP log data, along with a solid reporting layer. By leveraging the power of a custom-crafted, lightweight SIEM tool—which can interpret information from network security devices and server logs, allowing greater visibility, transmission, and storage of data—the parent DLP product can be integrated with the SIEM tool to create an advanced holistic solution, DLP – SIEM lite.

DLP

The DLP system is configured to send alerts, via a dedicated API, to the SIEM tool that was designed to receive these alerts, which were then processed accordingly. This multi-cloud integration can be tested to ensure the desired configuration was working as expected with a latency of less than 1m. Once tested, the SIEM tool could report and alert for investigation and response to data breaches.

Value Delivered: Future Proof and Real-Time

ü  Low-cost solution using cloud and open source, platform agnostic, pluggable, and extendable architecture to ingest more data sources

ü  Additional security capabilities are enabled, including real-time monitoring and alerting of sensitive data breaches

ü  Heavy expenditure on propriety SIEM tools can be avoided

ü  The entire process of identifying and notifying the data leaks can be automated

ü  Advanced, user-friendly dashboards and reporting features

Through this judicious combination of a proprietary DLP solution and the lightweight SIEM tool, crafted from mature Open-Source components, the objective of monitoring and plugging data leaks from endpoint devices in a short period is achieved, with only minimal OpEx, hitting the sweet spot at the intersection of hi-tech and optimum ROI!
