messages regarding the operation of deployed services and
application is an integral component to the forensic analysis for
the identification and understanding of security incidents.
Approaches for parsing and abstraction of such logs, despite
widespread use and study, do not directly account for the
individualities of the domain of information security. This, in
return, limits their applicability on the field. In this work, we
analyze the state-of-the-art log parsing and abstraction
algorithms from the perspective of information security. First, we
reproduce/replicate previous analysis of such algorithms from the
literature. Then, we evaluate their ability for parsing and
abstraction of log files for forensic analysis purposes. Our study
demonstrates that while the state-of-the-art techniques are
accurate in log parsing, improvements are necessary in terms of
achieving a holistic view to aid in forensic analysis for the
identification and understanding of security incidents. },
