Title: Dependability Challenges in Safety-Critical Systems: the adoption of Machine learning

Abstract: Machine Learning components in safety-critical applications can perform some complex tasks that would be unfeasible otherwise. However, they are also a weak point concerning safety assurance. We will illustrate two specific cases where ML must be incorporated in SCS with much care. One is related to the interactions between machine-learning components and other non-ML components and how they evolve with training of the former. We argue that it is theoretically possible that learning by the Neural Network may reduce the effectiveness of error checkers or safety monitors, creating a major complication for safety assurance. An example on automated driving is shown. Among the results, we observed that indeed improving the Controller could make the Safety Monitor less effective; to a limit where a training increment makes the Controller's own behavior safer but results in the vehicle to be less safe. The other one regards ML algorithms that perform binary classification as error, intrusion or failure detectors. They can be used in SCS provided that their performance complies with SCS safety requirements. However, the performance analysis of MLs relies on metrics that were not developed with safety in mind and consequently may not provide meaningful evidence to decide whether to incorporate a ML into a SCS. We analyze the distribution of misclassifications and thus show how to better assess the adequacy of a given ML.

 
RCL @ Grenoble - Machine Learning for CyberSecurity PDF Print E-mail

This year, RCL presented a contribution to the Machine Learning for CyberSecurity (MLCS 2022) workshop of the European Conference of Machine Learning (ECML), in Grenoble - France

 grenoble

The paper is entitled "Towards a General Model for Intrusion Detection: An Exploratory Study", and originated many questions and discussions from the audience.

Paper Abstract: Exercising Machine Learning (ML) algorithms to detect intrusions is nowa-days the de-facto standard for data-driven detection tasks. This activity re-quires the expertise of the researchers, practitioners, or employees of compa-nies that also have to gather labeled data to learn and evaluate the model that will then be deployed into a specific system. Reducing the expertise and time required to craft intrusion detectors is a tough challenge, which in turn will have an enormous beneficial impact in the domain. This paper conducts an exploratory study that aims at understanding to which extent it is possi-ble to build an intrusion detector that is general enough to learn the model once and then be applied to different systems with minimal to no effort. Therefore, we recap the issues that may prevent building general detectors and propose software architectures that have the potential to overcome them. Then, we perform an experimental evaluation using several binary ML classifiers and a total of 16 feature learners on 4 public attack datasets. Re-sults show that a model learned on a dataset or a system does not generalize well as is to other datasets or systems, showing poor detection performance. Instead, building a unique model that is then tailored to a specific dataset or system may achieve good classification performance, requiring less data and far less expertise from the final user.

Title: Intrusion Detection Through (Unsupervised) Machine Learning: Pros, Limitations and Workarounds

Abstract: It is undeniable that new cyber-attacks are continuously crafted against essentially any kind of system and service. Systems are subject to a mix of usual practiced attacks and new ones that were not previously known, motivating the need for building Intrusion Detectors (IDs) that can effectively deal with those zero-day attacks. Different studies have been devised Unsupervised Machine Learning (ML) algorithms belonging to different families as clustering, neural networks, density-based, neighbor-based, statistical, and classification. Those algorithms have the potential to detect even unknown threats thanks to a training phase that does not rely on labels in data. The talk shows how different algorithms are better suited for the detection of specific anomalies of system indicators, which manifest when attacks are conducted against a system. Unfortunately, those algorithms show inferior detection performance of known threats with respect to supervised ML algorithms; to fill this gap, we show improvements achieved when adopting Meta-Learning techniques. In any case, the quality of the best solution that can be devised depends strongly on the problem at hand and demands for high cost for selecting and finding the optimal set up of Unsupervised algorithms. To this end, we conclude the talk by proposing a cheap method to quantitatively understand the achievable results without exercising the full optimization activities.
