Configuration and change management standard
Supplier-defined controls
Configuration and change management approach
For Splunk initiated changes, maintenance is performed at most once per month and Customers will receive notice of Routine Maintenance by email at least 48 hours in advance. You can request an alternate time within the Routine Maintenance window if required. For Customer initiated changes, the maintenance can be performed regularly. Customer's will receive email notice when such maintenance is starting and when complete.

Vulnerability management type
Supplier-defined controls
Vulnerability management approach
We have a robust process for threats to the Splunk platform. We maintain a policy of evaluating all potential security vulnerabilities that are discovered internally or externally within two business days of discovery. We use the industry standard CVSSv2 to rate vulnerabilities. In the case of critical risk, high impact vulnerabilities, Splunk will make all reasonable effort to supply patches, assuming that patches are a viable stop-gap for customers who cannot otherwise upgrade Splunk.
Protective monitoring type
Supplier-defined controls
Protective monitoring approach
Splunk monitors application and platform components of the service for potential issues. Cloud Operations staff monitor alerts and logs for issues, and log a ticket for issues that require remediation. In the event of application or data compromise affecting customer data, the customer is notified immediately and remains in contact with the remediation team until resolution.

The security measures of Splunk and AWS are further described in the Technical Briefing paper at
Incident management type
Supplier-defined controls
