Abstract
Ontological data representation and data normalization can provide a structured way to correlate digital artifacts and reduce the amount of data that a forensics investigator needs to process in order to understand the sequence of events that happened on a system. However, ontology processing suffers from large disk consumption and a high computational cost. This paper presents Property Graph Event Reconstruction (PGER), a data normalization and event correlation system that utilizes a native graph database to store event data. This storage method leverages zero index traversals. PGER reduces the processing time of event correlation grammars by up to a factor of 9.9 times over a system that uses a relational database based approach.
