# Populate ECS fields from Security Events
#
# This script uses the key-value pairs from Security Events to populate
# the appropriate ECS fields.
#
# A single key can be mapped to multiple ECS fields, and more than one key can
# map to the same ECS field, which results in an array being created.
#
# This script performs an additional job:
#
# Before FTD version 6.3, the message_id was not included in Security Events.
# As this field encodes the kind of event (intrusion, connection, malware...)
# the script below will guess the right message_id from the keys present in
# the event.
#
# The reason for overloading this script with different behaviors is
# that this pipeline is already reaching the limit on script compilations.
