Scripted bitmask lookups for the Splunk Add-on for Crowdstrike

The Splunk Add-on for CrowdStrike FDR contains the following scripted lookup files.

These lookups represent mappings defined in the CrowdStrike documentation that provide information in the form of human readable strings to certain event field bitmask or flag values.

Bitmask or flag values are binary, where each bit indicates "turned on" (1) or "turned off"(2). For these fields, the Splunk Add-on for CrowdStrike FDR generates additional multivalue fields at search time by adding _meaning to the original field name. The new fields contain the interpretation of each raised bit of the field value.

The scripted lookup files map numerical values to lists of human readable strings, based on CrowdStrike's specification. The scripted lookup files are located in $SPLUNK_HOME/etc/apps/Splunk_TA_CrowdStrike_FDR/bin.
