TinyContainer: Container Runtime Middleware Enabling Multi-tenant Microcontrollers with Built-in Security

Software containerization technologies for resource-limited devices enable multi-tenant microcontrollers, which allow running multiple applications with different permission levels. However, current solutions lack run time configuration over various settings on container scheduling and container permissions to host resources. This limits the applicability of constrained containerization in dynamic and heterogeneous environments. This paper introduces TinyContainer, a lightweight software container management middleware designed for multi-tenant microcontrollers. TinyContainer provides per-container configurable scheduling and fine-grained access control to host resources through a metadata-driven approach, supporting multiple runtimes via a runtime abstraction layer. We analyze the performance of TinyContainer with a small WebAssembly runtime, CS4WAMR, and RIOT OS, a common RTOS. We report on experiments using popular IoT boards based on various Cortex-M microcontrollers. We show the endpoint system brought by TinyContainer allowing to regulate access of containers to host resources and provide host services to containers with an overhead of up to 4 ms per call. In particular, we showcase a TinyML use case, whereby containers retain data and model weights, while model inference is delegated to native host RTOS services.

A near-autonomous and incremental intrusion detection system through active learning of known and unknown attacks

Intrusion detection is a traditional practice of security experts, however, there are several issues which still need to be tackled. Therefore, in this paper, after highlighting these issues, we present an architecture for a hybrid Intrusion Detection System (IDS) for an adaptive and incremental detection of both known and unknown attacks. The IDS is composed of supervised and unsupervised modules, namely, a Deep Neural Network (DNN) and the K-Nearest Neighbors (KNN) algorithm, respectively. The proposed system is near-autonomous since the intervention of the expert is minimized through the active learning (AL) approach. A query strategy for the labeling process is presented, it aims at teaching the supervised module to detect unknown attacks and improve the detection of the already-known attacks. This teaching is achieved through sliding windows (SW) in an incremental fashion where the DNN is retrained when the data is available over time, thus rendering the IDS adaptive to cope with the evolutionary aspect of the network traffic. A set of experiments was conducted on the CICIDS2017 dataset in order to evaluate the performance of the IDS, promising results were obtained.

MESURE Tool to benchmark Java Card platforms

The advent of the Java Card standard has been a major turning point in smart card technology. With the growing acceptance of this standard, understanding the performance behavior of these platforms is becoming crucial. To meet this need, we present in this paper a novel benchmarking framework to test and evaluate the performance of Java Card platforms. MESURE tool is the first framework which accuracy and effectiveness are independent from the particular Java Card platform tested and CAD used.
