General Data Protection Regulation (GDPR) covers a wide range of data security issues, including data protection, accountability, data processing, consent from subjects, and privacy.
Because your organization does business in Europe, you have to ensure that the way your company handles data is in compliance with all parts of GDPR. The fines for non-compliance are extremely high, so you have little room for error.
You want to use Splunk to manage GDPR in-scope systems to ensure compliance. Specifically, you want to monitor who accesses what systems, what connections occur in your environment, whether systems are patched appropriately, and a number of other key indicators to guarantee compliance with GDPR and facilitate your ability to prove compliance.
How to use Splunk software for this use case
You can run many searches with Splunk software to help ensure compliance with GDPR. Depending on what information you have available, you might find it useful to identify some or all of the following:
- Access to unencrypted resources
- Activity from expired user identity
- Expected host not reporting events
- Geographically improbable access detected
- Device with outdated anti-malware
- Systems with the update service disabled
- New connection to device
- Unauthorized connection through firewall
- Unauthorized access to Splunk indexes
- Unauthorized access to systems
- Brute force access behavior detected
Measuring impact and benefit is critical to assessing the value of compliance operations. When implementing this use case, you should track the number of out-of-GDPR-compliance incidents detected over time. In addition, review compliance office requirements and reporting policies, and have a method of developing and maintaining an asset and identity catalog with in-scope attributes.
This use case is also included in the Splunk Security Essentials app, which provides more information about how to implement the use case successfully in your security maturity journey. In addition, these Splunk resources might help you understand and implement this use case:
