1. A system for dynamic chaffing for log obfuscation based on shifting exposure portfolio, the system comprising:
at least one non-transitory storage device; and
at least one processing device coupled to the at least one non-transitory storage device, wherein the at least one processing device is configured to:
receive an event log from one or more sources associated with a resource, wherein the event log comprises one or more event records, wherein the one or more event records are generated based on one or more action incidences;
initiate a chaffing engine on the event log;
generate, using the chaffing engine, one or more artificial records based on at least the one or more event records;
tag the one or more artificial records and the one or more event records with one or more authentication codes, wherein tagging the one or more artificial records further comprises:
generating, using the chaffing engine, one or more random authentication codes for the one or more artificial records; and
tagging, using the chaffing engine, the one or more artificial records with the one or more random authentication codes;
interleave, using the chaffing engine, the one or more artificial records and the one or more event records to generate an encrypted event log with one or more chaffed event records; and
store the encrypted event log in an event database.
