Comparison of Empirical Data from Two Honeynets and a Distributed Honeypot Network

In this paper we present empirical results and speculative analysis based on observations collected over a two month period from studies with two high interaction honeynets, deployed in a corporate and an SME (small to medium enterprise) environment, and a distributed honeypots deployment. All three networks contain a mixture of Windows and Linux hosts. We detail the architecture of the deployment and results of comparing the observations from the three environments. We analyze in detail the times between attacks on different hosts, operating systems, networks or geographical location. Even though results from honeynet deployments are reported often in the literature, this paper provides novel results analyzing traffic from three different types of networks and some initial exploratory models. This research aims to contribute to endeavours in the wider security research community to build methods, grounded on strong empirical work, for assessment of the robustness of computer-based systems in hostile environments

Originality/value – This is the first comparative study about features and implementation of DLS in HEC recognized universities in Punjab, Pakistan. This study will allow institutions, universities, and organizational libraries to move from traditional library systems to modern digital library systems due to the useful features reported by the participants. It will help to select a better software system to implement in their libraries. Keywords - Digital Library Software, Features of digital library software, D-space, e-prints, Greenstone, Fedora

Towards maintainer script modernization in FOSS distributions

Free and Open Source Software (FOSS) distributions are complex software systems, made of thousands packages that evolve rapidly, independently, and without centralized coordination. During packages upgrades, corner case failures can be encountered and are hard to deal with, especially when they are due to misbehaving maintainer scripts: executable code snippets used to finalize package configuration. In this paper we report a software modernization experience, the process of representing existing legacy systems in terms of models, applied to FOSS distributions. We present a process to define meta-models that enable dealing with upgrade failures and help rolling back from them, taking into account maintainer scripts. The process has been applied to widely used FOSS distributions and we report about such experiences

Collecting and Analyzing Failure Data of Bluetooth Personal Area Networks

This work presents a failure data analysis campaign on Bluetooth Personal Area Networks (PANs) conducted on two kind of heterogeneous testbeds (working for more than one year). The obtained results reveal how failures distribution are characterized and suggest how to improve the dependability of Bluetooth PANs. Specically, we dene the failure model and we then identify the most effective recovery actions and masking strategies that can be adopted for each failure. We then integrate the discovered recovery actions and masking strategies in our testbeds, improving the availability and the reliability of 3.64% (up to 36.6%) and 202% (referred to the Mean Time To Failure), respectively

DEPLOYMENT AND USABILITY EVALUATION OF MOBILE ACCESS TO INSTITUTIONAL REPOSITORY

An Institutional Repository is essentially a web application that is capable of capturing, preserving and disseminating the intellectual output of a University or research institution in dig ital formats. The advent of the Mobile Web has ushered in a new wave of mobile devices - with multi-touch facilities and thus there has been a shift from Web access to Mobile Web access. This has brought about the need to make web applications accessible via mobile devices. This study investigated the usability of the core functionalities of an Institutional Repository on various mobile devices. The work did not try to create a mobile version of the repository but rather test the existing web application on various mobile platforms. To achieve this, the core functionalities of the repository were modelled using Unified Modelling Language (UML). In addition, an Institutional Repository was built and deployed for Covenant University by leveraging on open source repository software – EPrints. Furthermore, the core functionalities of the Institutional Repository were tested on five different mobile devices. Finally, the usability of the Institutional Repository on the various mobile devices used was evaluated by identifying the usability attributes; designing a questionnaire based on those attributes and then analyzing the results with SPSS software. The results showed that overall the current web version of the repository had a good usability score on the mobile devices used

Revisão de diferentes implementações para a preservação digital: para uma proposta metodológica de preservação e auditoria de confiança de RI

This work introduces the initial experience of an infrastructure for digital documents preservation in archives or repositories. Prior backgrounds of similar infrastructures are recognized in this work, and among them three successful experiences are described. These experiences are all aimed to connect a digital repository with different software tools able to ensure digital preservation of repository contents according to OAIS ISO 14721 standard (2012). After the description of the three models, we describe a prototype under development in the repositories supported by PREBI-SEDICI (UNLP), which uses the software tools DSpace, Archivematica and ArchivesSpace. In this prototype, DSpace handles the ingest and delivery of digital contents, while Archivematica performs all the required digital preservation activities. This is achieved through a set of microservices applied to a conceptual structure similar to the information package (IP) in its different versions (SIP, AIP, DIP). The resulting structure of the IP includes checksums, original files, logs, transfer documentation and XML metadata. The main purpose of this work is to show the background activities already carried out in institutions around the world, and to start a research project aiming to generate ideas and thoughts in the Latin American context.Este trabalho relaciona a experiência inicial de testar uma estrutura adequada para a preservação de documentos digitais em um arquivo ou repositório. Numerosos antecedentes de estruturas similares são reconhecidos e, dentre eles, três experiências de sucesso dedicadas a conectar um repositório com ferramentas capazes de garantir a preservação digital de conteúdos seguindo o modelo OAIS, ISO 14721 (2012) são brevemente descritas. Depois de descrever estes três modelos considerados mais relevantes, um protótipo é contada em evidência em repositórios gerenciados em PrEBi-SEDICI (UNLP) com DSpace, Archivematica e ferramentas ArchivesSpace no repositório DSpace está a cargo de renda e entrega de conteúdo digital enquanto a estrutura do Archivematica realiza atividades de preservação digital através da implementação de um conjunto de microsserviços, que atuam sobre uma estrutura conceitual assimilável ao pacote de informações (IP) em suas diferentes versões. A estrutura física resultante do pacote de informações em suas diferentes versões (SIP, AIP, DIP) inclui arquivos, soma de verificação, logs, documentação da transferência e metadados em uma estrutura XML. Este trabalho não tem mais pretensões do que mostrar os antecedentes e o início de um trabalho de pesquisa com o objetivo de gerar consultas e reflexões no contexto latino-americano, onde essas questões são incipientes.Este trabajo relata la experiencia inicial de prueba de una estructura apta para la preservación de documentos digitales en un archivo o repositorio.
