Splunk Data Loss Prevention (DLP) Guide | Nightfall Developer Platform

Guide to Cloud Data Loss Prevention (DLP) on Splunk

Learn how to discover, classify, and protect sensitive data in Splunk with Nightfall’s APIs. Improve security & compliance with cloud data loss prevention.
The Challenge

Data Sprawl on Splunk

  • Splunk is an analytics platform for searching, monitoring, and analyzing machine-generated data. Sensitive data like PII, credentials & secrets sprawl into Splunk at an alarming rate. It’s nearly impossible to know what types of data are in Splunk through manual efforts.
  • Splunk doesn’t have enterprise-grade data protection, DLP, or data classification capabilities built-in.
  • Current data protection solutions are built for devices and networks, not cloud services like Splunk, so they are hard to implement. They aren’t flexible, accurate, or developer-friendly because they are primarily based on regular expressions and simple heuristics.
  • This can lead to productivity loss, risk of data breach, and compliance problems.
+
  • Programmatically get structured results from Nightfall’s detectors for many types of sensitive data like credit card numbers and API keys. Nightfall maintains a growing library of detectors that include personally identifiable information (PII) and other data types as defined by data privacy regulations, such as GDPR, PCI-DSS, and HIPAA.
  • Deep-learning based detectors go well beyond regexes, rules, and search strings so you can make sense of your data without the alert fatigue. These detection techniques continually improve over time.
  • Customizable detection engine to tailor detectors and detection rules to your needs.
  • Custom-defined data types using regular expressions or word lists, to discover proprietary or unique sensitive data specific to your use cases.
  • Scan a broad range of file types and MIME-types, and perform machine learning based optical character recognition (OCR) to extract text.
  • Nightfall Dashboard enables you to create, save, and manage detection rules easily and flexibly in the UI to reference in code.
  • Integration example & starter code for integrating directly with Splunk so you don’t need to write the integration glue from scratch.
Instructions

Using Nightfall & Splunk APIs

  • Create an API key. Integrate with just a few lines of code.
  • Configure a detection rule. Set up detection rules as code or manage them in the Nightfall Console. Use our Playground to test detection rules easily.
  • Make your first API call. Scan text payloads or files with 150+ detectors trained via machine learning.
  • Read our integration example & starter code for Splunk. We make integration quick and painless with clear and comprehensive documentation.
