IPAL: Breaking up Silos of Protocol-dependent and Domain-specific Industrial Intrusion Detection Systems
The increasing interconnection of industrial networks exposes them to an
ever-growing risk of cyber attacks. To reveal such attacks early and prevent
any damage, industrial intrusion detection searches for anomalies in otherwise
predictable communication or process behavior. However, current efforts mostly
focus on specific domains and protocols, leading to a research landscape broken
up into isolated silos. Thus, existing approaches cannot be applied to other
industries that would equally benefit from powerful detection. To better
understand this issue, we survey 53 detection systems and find no fundamental
reason for their narrow focus. Although they are often coupled to specific
industrial protocols in practice, many approaches could generalize to new
industrial scenarios in theory. To unlock this potential, we propose IPAL, our
industrial protocol abstraction layer, to decouple intrusion detection from
domain-specific industrial protocols. After proving IPAL's correctness in a
reproducibility study of related work, we showcase its unique benefits by
studying the generalizability of existing approaches to new datasets and
conclude that they are indeed not restricted to specific domains or protocols
and can perform outside their restricted silos

Complete mitochondrial DNA sequences provide new insights into the Polynesian motif and the peopling of Madagascar
More than a decade of mitochondrial DNA (mtDNA) studies have given the 'Polynesian motif' renowned status as a marker for tracing the late-Holocene expansion of Austronesian speaking populations. Despite considerable research on the Polynesian motif in Oceania, there has been little equivalent work on the western edge of its expansion - leaving major issues unresolved regarding the motif's evolutionary history. This has also led to considerable uncertainty regarding the settlement of Madagascar. In this study, we assess mtDNA variation in 266 individuals from three Malagasy ethnic groups: the Mikea, Vezo, and Merina. Complete mtDNA genome sequencing reveals a new variant of the Polynesian motif in Madagascar; two coding region mutations define a Malagasy-specific sub-branch. This newly defined 'Malagasy motif' occurs at high frequency in all three ethnic groups (13-50%), and its phylogenetic position, geographic distribution, and estimated age all support a recent origin, but without conclusively identifying a specific source region. Nevertheless, the haplotype's limited diversity, similar to those of other mtDNA haplogroups found in our Malagasy groups, best supports a small number of initial settlers arriving to Madagascar through the same migratory process. Finally, the discovery of this lineage provides a set of new polymorphic positions to help localize the Austronesian ancestors of the Malagasy, as well as uncover the origin and evolution of the Polynesian motif itself
