- Abstract: The computing device deployment explosion experienced in recent years,
motivated by the advances of technologies such as Internet-of-Things (IoT) and
5G, has led to a global scenario with increasing cybersecurity risks and
threats. Among them, device spoofing and impersonation cyberattacks stand out
due to their impact and, usually, low complexity required to be launched. To
solve this issue, several solutions have emerged to identify device models and
types based on the combination of behavioral fingerprinting and Machine/Deep
Learning (ML/DL) techniques. However, these solutions are not appropriated for
scenarios where data privacy and protection is a must, as they require data
centralization for processing. In this context, newer approaches such as
Federated Learning (FL) have not been fully explored yet, especially when
malicious clients are present in the scenario setup. The present work analyzes
and compares the device model identification performance of a centralized DL
model with an FL one while using execution time-based events. For experimental
purposes, a dataset containing execution-time features of 55 Raspberry Pis
belonging to four different models has been collected and published. Using this
dataset, the proposed solution achieved 0.9999 accuracy in both setups,
centralized and federated, showing no performance decrease while preserving
data privacy. Later, the impact of a label-flipping attack during the federated
model training is evaluated, using several aggregation mechanisms as
countermeasure. Zeno and coordinate-wise median aggregation show the best
performance, although their performance greatly degrades when the percentage of
fully malicious clients (all training samples poisoned) grows over 50%.
