Pełny tekst źródłaThe 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

Pełny tekst źródłaNetwork anomalies, and specifically distributed denial of services attacks, are still an important threat to the Internet stakeholders. Detecting such anomalies requires dedicated tools, not only able to perform an accurate detection but also to meet the several constraints due to an industrial operation. Such constraints include, amongst others, the ability to run autonomously or to operate on sampled traffic. Unlike supervised or signature-based approaches, unsupervised detection do not require any kind of knowledge database on the monitored traffic. Such approaches rely on an autonomous characterization of the traffic in production. They require the intervention of the network administrator a posteriori, when it detects a deviation from the usual shape of the traffic. The main problem with unsupervised detection relies on the fact that building such characterization is complex, which might require significant amounts of computing resources. This requirement might be deterrent, especially when the detection should run on network devices that already have a significant workload. As a consequence, we propose a new unsupervised detection algorithm that aims at reducing the computing power required to run the detection. Its detection focuses on distributed denial of service attacks. Its processing is based upon the creation, at a regular interval, of traffic snapshots, which helps the diagnosis of detected anomalies. We evaluate the performances of the detector over two datasets to check its ability to accurately detect anomalies and to operate, in real time, with limited computing power resources. We also evaluate its performances over sampled traffic. The results we obtained are compared with those obtained with FastNetMon and UNADA

Pełny tekst źródłaEmbedded systems are processing and handling more and more sensitive data. The security of these systems is now a prime concern for those who designs them. Fault attacks are indented to disrupt the execution of programs through the manipulation of physical quantities in the system environment and enable an attacker to bypass security mechanisms or achieve privilege escalation. Software counter-measures are deployed to address this threat. Various analyses are now being used to assess the efficiency of the counter-measures once deployed but they are little or not automated, costly and limited in terms of code coverage of the possible behaviour and of faults types that can be analysed. We propose a method to analyse the robustness of binary code combining formal methods and symbolic execution. Performing the analysis at the binary positions the analysis after compilation which can affect the counter-measures and allows it to take into account information which is only visible at the binary level and which can be exploited to perform an attack. Formal methods are capable of exhaustiveness and thus allow the analysis to consider all possible configurations of inputs. The proposed analysis is nevertheless carried out with respect to a symbolic context, extracted by symbolic execution, which confines it to a realistic set of inputs and thus limits false positives. We have implemented this method in a tool called \texttt{RobustB}. It is automated from the source code. We propose three metrics synthesising the analysis results and helping the designer of counter-measures to assess the sensitivity of the code as a whole and at the granularity of an instruction

Pełny tekst źródłaWireless networks are nowadays indispensable components of telecommunication infrastructures. They offer flexibility, mobility and rapid expansion of telecommunication infrastructures. They are also particularly needed to connect mobile devices such as connected cars, watches and drones. Wireless networks are also used in the transport and security sector to connect trains and cameras to monitoring systems. However, in contrary to wired networks in which transmission are isolated in wires, in wireless networks, transmissions are emitted using omnidirectional antennas. This makes wireless networks more vulnerable to unauthorised listening, emission and some specific attacks. In this thesis, we have worked on the detection of three different types of attacks on IEEE 802.11 (Wi-Fi) networks. The three attacks are fake access points and two denial of service attacks namely, deauthentication and jamming attacks. In scientific literature, these three attacks are detected independently and using one or two indicators.We propose a method that uses classification algorithms to create a model that can detect the three attacks by analysing four indicators simultaneously. The model can detect the attacks when they are perpetuated independently and also when they are combined. Concerning data used to create the model, among the three different types of frames that can be transmitted on Wi-Fi networks, we have considered only management frames and more particularly, beacon frames. Beacon frames are sent at regular interval and even in the absence of user traffic. Therefore, basing the detection on the analysis of beacon frames leads to a more efficient detection. In this thesis, we have also considered variations in data rates (absence of user traffic, light, moderate and intense user traffic) and in jamming power (low, moderate and high jamming power). Results show that the model can detect fake access points, deauthentication and jamming attacks (low and moderate power) with high precision. The jamming attack with intense power is detected with satisfying precision. By considering the beacon frames of a farther second access point of the network, we have been able to increase detection precision in the latter case. Finally, we have considered special cases such as Wi-Fi transmissions in the 5 GHz band and the phantom fake access point attack

Pełny tekst źródłaOne of the major challenges of the world in recent decades is the continued increase in the elderly population in developed countries. Hence the need to provide quality care to a rapidly growing population while reducing the costs of health care is becoming a strategic challenge. In this context, many researches focus on the use of wireless sensor networks in WBAN (Wireless Body Area Network) systems to facilitate and improve the quality of medical care and remote monitoring. These WBAN systems pose new technological challenges in terms of security and protection against faults and attacks. The wireless communication mode used between the sensors and the collection node accentuates these vulnerabilities. Indeed vulnerabilities in a WBAN system are divided into two main parts. The first part consists of the possible attacks on the network of medical sensors and on the wireless communications medium between the sensors and the processing unit. The second part consists of possible attacks on high-speed communications between the WBAN system and the medical server. The objective of this thesis is to meet some of the problems of detecting attacks in a WBAN system for remote medical monitoring. To achieve this goal, we propose an algorithm to detect the jamming attacks targeting the wireless communications medium between the sensors and the processing unit. In addition we propose a method of measuring divergence to detect the flooding attacks targeting the high-speed communications between the WBAN system and the medical server

Pełny tekst źródłaIn recent years, computer systems have evolved quickly. This evolution concerns different layers of the system, both software (operating systems and user programs) and hardware (microarchitecture design and chip technology). While this evolution allows to enrich the functionalities and improve the performance, it has also increased the complexity of the systems. It is difficult, if not impossible, to fully understand a particular modern computer system, and a greater complexity also stands for a larger attack surface for hackers. While most of the attacks target software vulnerabilities, over the past two decades, attacks exploiting hardware vulnerabilities have emerged and demonstrated their serious impact. For example, in 2018, the Spectre and Meltdown attacks have been disclosed, that exploited vulnerabilities in the microarchitecture layer to allow powerful arbitrary reads, and highlighted the security issues that can arise from certain optimizations of system microarchitecture. Detecting and preventing such attacks is not intuitive and there are many challenges to deal with: (1) the great difficulty in identifying sources of vulnerability implied by the high level of complexity and variability of different microarchitectures; (2) the significant impact of countermeasures on overall performance and on modifications to the system's hardware microarchitecture generally not desired; and (3) the necessity to design countermeasures able to adapt to the evolution of the attack after deployment of the system. To face these challenges, this thesis focuses on the use of information available at the microarchitecture level to build efficient attack detection methods.In particular, we describe a framework allowing the dynamic detection of attacks that leave fingerprints at the system's microarchitecture layer. This framework proposes: (1) the use microarchitectural information for attack detection, which can effectively cover attacks targeting microarchitectural vulnerabilities; (2) a methodology that assists designers in selecting relevant microarchitectural information to extract; (3) the use of dedicated connections for the transmission of information extracted, in order to ensure high transmission bandwidth and prevent data loss; and (4) the use of reconfigurable hardware in conjunction with software to implement attack detection logic. This combination (composing to the so-called detection module) reduces the performance overhead through hardware acceleration, and allows updating detection logic during the system lifetime with reconfiguration in order to adapt to the evolution of attacks. We present in detail the proposed architecture and modification needed on the operating system, the methodology for selecting appropriate microarchitectural information and for integrating this framework into a specific computer system, and we describe how the final system integrating our detection module is able to detect attacks and adapt to attack evolution. This thesis also provides two use-case studies implemented on a prototype (based on a RISC-V core with a Linux operating system) on an FPGA. It shows that, thanks to the analysis of microarchitectural information, relatively simple logic implemented in the detection module is sufficient to detect different classes of attacks (cache side-channel attack and ROP attack)
