A
system, method, and computer-program product includes obtaining raw
event data associated with a subscriber, automatically selecting an automated event
ingestion instruction of a plurality of distinct automated event
ingestion instructions for
processing the raw
event data, automatically generating a pre-normalized security event that includes the raw
event data in a first structured data object in response to executing the automated event
ingestion instruction, automatically transforming the pre-normalized security event to at least one normalized security event, automatically assessing a corpus of computer-
executable detection instructions against the at least one normalized security event, generating a security alert based on the at least one normalized security event satisfying a set of alerting conditions of a subject computer-
executable detection instruction of the corpus of computer-
executable detection instructions, and executing a
threat mitigation response that mitigates a security
threat associated with the security alert.
