The SSP is a very effective protection technique used against stack buffer overflows

Abstract Microsoft’s Windows Operating System provides a logging service that collects, filters and stores event messages from the kernel and applications into log files (.evt and .evtx).

Currently there is no support for users to extract the event logs (.evtx) from Windows Vista, Win7 or Win8 memory dumps, and Volatility users have to rely on outside software in order to do this.

Thirty years ago, research in designing operating systems to defeat malicious software was very popular. The primary technique was to design and implement a small security kernel that could provide security assurances to the rest of the system. However, as operating systems grew in size throughout the 1980's and 1990's, research into security kernels slowly waned. From a security perspective, the story was bleak. Providing security to one of these large operating systems typically required running software within that operating system. This weak security foundation made it relatively easy

To protect against brute force attacks, modern password-based authentication systems usually employ mechanisms known as Password Hashing Schemes (PHS). Basically, a PHS is a cryptographic algorithm that generates a sequence of pseudorandom bits from a user-defined password, allowing the user to configure the computational costs involved in the process aiming to raise the costs of attackers testing multiple passwords trying to guess the correct one. Traditional schemes such as PBKDF2 and bcrypt, for example, include a configurable parameter that controls the number of iterations performed, allo

While solutions for file system encryption can prevent an adversary from determining the contents of files, in situations where a user wishes to hide even the existence of data, encryption alone is not enough. Indeed, encryption may draw attention to those files, as they most likely contain information the user wishes to keep secret, and coercion can be a very strong motivator for the owner of an encrypted file system to surrender their secret key. Herein we present DEFY, a deniable file system designed to work exclusively with solid-state drives, particularly those found in mobile devices. So

Today’s forensic investigators are often subject to large case backlogs, and incident responders must be able to quickly identify the source and cause of security breaches.

This thesis utilises the context of European Holocaust memory to test differences within the existing literature of the theory of ‘ontological security’. The differences centre on questions of identity preservation in the face of threats to a states ‘sense of self’. The paper builds a connection between theories within the field of collective memory and ontological security (a sub-field known as ‘mnemonic security’) and applies these to two case studies within the European context: the UK and Poland. These cases were chosen based on disparity of experience of the Holocaust within the European

In this paper, we present a working research prototype codeid-elf for ELF binaries based on its Windows counterpart codeid, which can identify kernels through relocation entries extracted from the binaries. We show that relocation-based signatures are unique and distinct and thus, can be used to accurately determine Linux kernel versions and derandomize the base address of the kernel in memory (when kernel Address Space Layout Randomization is enabled). We evaluate the effectiveness of codeid-elf on a subset of Linux kernels and find that the relocations in kernel code have nearly 100\% code c

This dissertation investigates and introduces novel algorithms, theories, and supporting frameworks to significantly improve the growing problem of Internet security. A distributed firewall and active response architecture is introduced that enables any device within a cyber environment to participate in the active discovery and response of cyber attacks. A theory of semantic association systems is developed for the general problem of knowledge discovery in data. The theory of semantic association systems forms the basis of a novel semantic path merger packet classification algorithm. The theo

Android forensics has evolved over time offering significant opportunities and exciting challenges. On one hand, being an open source platform Android is giving developers the freedom to contribute to the rapid growth of the Android market whereas on the other hand Android users may not be aware of the security and privacy implications of installing these applications on their phones. Users may assume that a password-locked device protects their personal information, but applications may retain private information on devices, in ways that users might not anticipate. In this thesis we will be c

L'Internet des Objets, raccourcie en IoT pour Internet of Things, est un écosystème en pleine expansion, où des objets intelligents interagissent via des réseaux communicants. Cette croissance rapide entraîne une augmentation massive des données collectées, posant des défis en termes d'efficacité énergétique, notamment au niveau des nœuds de capteurs. Pour améliorer cette efficacité, il est essentiel de traiter les données au plus près des capteurs, ce qui réduit la charge de communication et d'opérations sur l'unité de calcul principale.

Les mémoires magnétiques (MRAM) font partie des technologies de mémoires non volatiles émergentes ayant connu un développement rapide cette dernière décennie. Un des avantages de cette technologie réside dans les domaines d’applications variées dans lesquelles elle peut intervenir. En plus de sa fonction principale de stockage d’information, la MRAM est utilisée de nos jours dans des applications de type capteurs, récepteur RF et sécurité matérielle. Dans cette thèse, nous nous sommes intéressés à l’utilisation des MRAM dans la conception des primitives de sécurité matérielle élémentaires. Dan

Este documento apresenta o Lyra, um novo esquema de derivação de chaves, baseado em esponjas criptográficas. O Lyra foi projetado para ser estritamente sequencial, fornecendo um nível elevado de segurança mesmo contra atacantes que utilizem múltiplos núcleos de processamento, como uma GPU ou FPGA. Ao mesmo tempo possui uma implementação simples em software e permite ao usuário legítimo ajustar o uso de memória e tempo de processamento de acordo com o nível de segurança desejado. O Lyra é, então, comparado ao scrypt, mostrando que esta proposta fornece um nível se segurança mais alto, além de s

La croissance des flux d'information à travers le monde est responsable d'une importante utilisation de systèmes embarqués temps-réel, et ce notoirement dans le domaine des satellites. La présence de ces systèmes est devenue indispensable pour la géolocalisation, la météorologie, ou les communications. La forte augmentation du volume de ces matériels, impactée par l'afflux de demande, est à l'origine de l'accroissement de la complexité de ces derniers. Grâce à l'évolution du matériel terrestre, le domaine aérospatial se tourne vers de nouvelles technologies telles que les caches, les multi-coe
