Toure, Almamy. "Collection, analysis and harnessing of communication flows for cyber-attack detection". Electronic Thesis or Diss., Valenciennes, Université Polytechnique Hauts-de-France, 2024. http://www.theses.fr/2024UPHF0023.
Testo completoThe increasing complexity of cyberattacks, characterized by a diversification of attack techniques, an expansion of attack surfaces, and growing interconnectivity of applications with the Internet, makes network traffic management in a professional environment imperative. Companies of all types collect and analyze network flows and logs to ensure the security of exchanged data and prevent the compromise of information systems. However, techniques for collecting and processing network traffic data vary from one dataset to another, and static attack detection approaches have limitations in terms of efficiency and precision, execution time, and scalability. This thesis proposes dynamic approaches for detecting cyberattacks related to network traffic, using feature engineering based on the different communication phases of a network flow, coupled with convolutional neural networks (1D-CNN) and their feature detector. This double extraction allows for better classification of network flows, a reduction in the number of attributes and model execution times, and thus effective attack detection. Companies also face constantly evolving cyber threats, and "zero-day" attacks that exploit previously unknown vulnerabilities are becoming increasingly frequent. Detecting these zero-day attacks requires constant technological monitoring and thorough but time-consuming analysis of the exploitation of these vulnerabilities. The proposed solutions guarantee the detection of certain attack techniques. Therefore, we propose a detection framework for these attacks that covers the entire attack chain, from the data collection phase to the identification of any type of zero-day, even in a constantly evolving environment. Finally, given the obsolescence of existing datasets and data generation techniques for intrusion detection, and the fixed, non-evolving, and non-exhaustive nature of recent attack scenarios, the study of an adapted synthetic data generator while ensuring data confidentiality is addressed. The solutions proposed in this thesis optimize the detection of known and zero-day attack techniques on network flows, improve the accuracy of models, while ensuring the confidentiality and high availability of data and models, with particular attention to the applicability of the solutions in a company network
Peng, Tao. "Analyse de données loT en flux". Electronic Thesis or Diss., Aix-Marseille, 2021. http://www.theses.fr/2021AIXM0649.
Testo completoSince the advent of the IoT (Internet of Things), we have witnessed an unprecedented growth in the amount of data generated by sensors. To exploit this data, we first need to model it, and then we need to develop analytical algorithms to process it. For the imputation of missing data from a sensor f, we propose ISTM (Incremental Space-Time Model), an incremental multiple linear regression model adapted to non-stationary data streams. ISTM updates its model by selecting: 1) data from sensors located in the neighborhood of f, and 2) the near-past most recent data gathered from f. To evaluate data trustworthiness, we propose DTOM (Data Trustworthiness Online Model), a prediction model that relies on online regression ensemble methods such as AddExp (Additive Expert) and BNNRW (Bagging NNRW) for assigning a trust score in real time. DTOM consists: 1) an initialization phase, 2) an estimation phase, and 3) a heuristic update phase. Finally, we are interested predicting multiple outputs STS in presence of imbalanced data, i.e. when there are more instances in one value interval than in another. We propose MORSTS, an online regression ensemble method, with specific features: 1) the sub-models are multiple output, 2) adoption of a cost sensitive strategy i.e. the incorrectly predicted instance has a higher weight, and 3) management of over-fitting by means of k-fold cross-validation. Experimentation with with real data has been conducted and the results were compared with reknown techniques

Testo completoComplex embedded systems (planes, satellites, drones ...) contain more and more calculators. From now on, these are tens or even hundreds of calculators that communicate through a shared network. A function is achieved by the collaboration of a set of devices that exchange a growing number of information. In an embedded real-time context, it must be ensured that these informations exchanged are correct but it must also be ensured that they verify their temporal constraints. From the network point of view, this means that informations must be exchanged respecting their deadlines. This implies being able to upper bound the traversal time of the network of each message in order to verify that it arrives in time. However, as embedded systems are more and more complex and as the amount of information exchanged is constantly increasing, this bound is increasingly difficult to compute. Furthermore, it is important that this upper bound to be the least pessimistic possible to avoid an oversized system.The goal of this work is to develop new methods of analysis in order to be able to compute these bounds.In order to achieve this, we used the Network Calculus method of analysis.This work focuses on the modeling of interactions between synchronous messages and asynchronous messages.The models presented in this work take into account the transmission dates on the network of synchronous messageswhen calculating the upper bounds of traversal time of the asynchronous messages.The main contributions are:1. the presentation of a new way of considering the use of the dates of emission on the CAN bus: the weak synchronization.As well as the complete modeling of such a system and finally the evaluation of the gain provided by this solution.2. a complete modeling of the TTEthernet network allowing to evaluate the impact of the synchronous flows on the traversal time of the asynchronous flows.3. a presentation of the use of synchronization in the TSN network and a complete model for analyzing this new technology
Allaert, Benjamin. "Analyse des expressions faciales dans un flux vidéo". Thesis, Lille 1, 2018. http://www.theses.fr/2018LIL1I021/document.
Testo completoFacial expression recognition has attracted great interest over the past decade in wide application areas, such as human behavior analysis, e-health and marketing. In this thesis we explore a new approach to step forward towards in-the-wild expression recognition. Special attention has been paid to encode respectively small/large facial expression amplitudes, and to analyze facial expressions in presence of varying head pose. The first challenge addressed concerns varying facial expression amplitudes. We propose an innovative motion descriptor called LMP. This descriptor takes into account mechanical facial skin deformation properties. When extracting motion information from the face, the unified approach deals with inconsistencies and noise, caused by face characteristics. The main originality of our approach is a unified approach for both micro and macro expression recognition, with the same facial recognition framework. The second challenge addressed concerns important head pose variations. In facial expression analysis, the face registration step must ensure that minimal deformation appears. Registration techniques must be used with care in presence of unconstrained head pose as facial texture transformations apply. Hence, it is valuable to estimate the impact of alignment-related induced noise on the global recognition performance. For this, we propose a new database, called SNaP-2DFe, allowing to study the impact of head pose and intra-facial occlusions on expression recognition approaches. We prove that the usage of face registration approach does not seem adequate for preserving the features encoding facial expression deformations

Testo completoThis thesis deals with the creation and management of general purpose summaries build from data streams. It is centered on the development of two algorithms, one designed to produce general purpose summaries for a single data stream, and the other for three data stream sharing relational information. A data stream is defined as a real-time, continuous, ordered sequence of items. It is impossible to control the order in which items arrive, nor is it feasible to locally store a stream in its entirety. Such data streams appear in many applications, such as utility networks, IT or in monitoring tasks for instance in meteorology, geology or even finance. The first step in this work is to define the meaning of a general purpose data stream summary. The first property of such a summary is that it should be suitable for a variety of data mining and querying tasks. The second one is that it should be possible to build from the main summary a summary concerning only a selected portion of the stream encountered so far. The first algorithm designed, StreamSamp, is a general purpose summary algorithm dealing with a single data stream and based around the principle of sampling. While the second algorithm, CrossStream, is is a general purpose summary algorithm dealing with three data streams sharing relational information with one another, one relation stream linking two entity streams. This algorithm is based on the use of micro clusters, inspired by the CluStream algorithm designed by Aggarwal combined with the use of Bloom Filter. Both algorithm were implemented and tested against various sets of data to assess their performance in a number of situations

Testo completoValuation is important in many fields of finance, such as corporate finance, mergers and acquisitions or portfolio management. Whereas it is limited for indexed funds management, valuation represents a great issue for an active portfolio management. In the capital-value theory, valuation with dividend discount models shows some insufficiencies, which may be corrected by the use of other flows, the "free cash flow". The empirical study on the french market allowed us to compare how relevant several indicators were, among which some were linked to free cash flows and some were financial ratios. The results show that the indicators we proposed are significant in the market valuation of stocks, and therefore relevant in active management
