The data in Splunk is now subject to auditing and compliance controls. A customer would like to ensure that at least one year of logs are retained for both Windows and Firewall events. What data retention controls must be configured?
The data retention controls that must be configured to ensure that at least one year of logs are retained for both Windows and Firewall events are maxTotalDataSizeMB and frozenTimePeriodInSecs. These settings are defined in the indexes.conf file, which specifies the index settings and data retention policies for Splunk. The maxTotalDataSizeMB setting determines the maximum size of an index, in megabytes. When the index reaches this size, the oldest data is frozen (deleted or archived). The frozenTimePeriodInSecs setting determines the maximum age of the data in an index, in seconds. When the data exceeds this age, it is frozen. Therefore, by setting these values appropriately for the Windows and Firewall indexes, the customer can ensure that at least one year of logs are retained. References:
