Declaration of Committee Name: Noelle Warkentin Degree: Master of Arts Title: Identifying Information Useful for Cyber-Attacks Against Canadian Critical Infrastructure in Online Discussion Forums Committee: Chair: Sheri Fabian University Lecturer, School of Criminology Richard Frank Supervisor Associate Professor, School of Criminology Bryan Kinney Committee Member Associate Director, School of Criminology Aunshul Rege External Examiner Associate Professor, Department of Criminal Justice Temple University ii Abstract Critical infrastructures (CI) are connecting their systems to networks at an increasing rate, providing the opportunity for malicious actors to conduct cyber-attacks against these companies. In an attempt to understand the threats facing Canada’s CI, information collected from online discussion forums was analyzed to discover frequently targeted CI companies and locations in Canada, the types of information shared within these forums, and who the main authors are in sharing threat-related posts. After analyzing IP addresses collected from 20 online discussion forums, the province of Quebec was identified as a hot-spot for cyber-threats, while the information and technology sector was targeted most frequently among sectors. A thematic analysis of posts containing keywords revealed that information useful for conducting cyber-attacks against CI is being shared within these forums. Lastly, findings from this study found two authors may be considered high-threat, in that the majority of their posts were threatening towards CI. Keywords: critical infrastructure; cyber security; hacking; thematic analysis; online discussion forums iii Acknowledgements I would like to acknowledge my family and close friends who have supported me endlessly on my endeavors in not only completing this thesis, but also throughout my studies. In particular, my mom has inspired me to achieve my goals, and was also my constant source of support during the graduate program. If I hadn’t watched her make her way through university when I was a child, I’m not sure I would be where I am today, and I am forever grateful for her guidance. Of course, I must also thank my supervisor, Dr. Richard Frank, for providing me with the opportunities that have led me to study cyber-threats against critical infrastructure. Having never studied cyber related crimes during my undergraduate years, I never would have realized my interest in this field if it weren’t for him. Not only has he helped spark my curiosity in cyber-threats and cybercrimes, he has also helped me immensely by assisting me in developing my skills as a researcher, and as a writer. iv Table of Contents Declaration of Committee .................................................................................................... ii Abstract ............................................................................................................................... iii Acknowledgements ............................................................................................................. iv Table of Contents .................................................................................................................v List of Tables ...................................................................................................................... vii List of Figures.................................................................................................................... viii List of Maps ......................................................................................................................... ix List of Acronyms ..................................................................................................................x Chapter 1.

  • Cologix Torix Case Study
    Internet Exchange Case Study The Toronto Internet Exchange (TorIX) is the largest IX in Canada with more than 175 peering participants benefiting from lower network costs & faster speeds The non-profit Toronto Internet Exchange (TorIX) is a multi-connection point enabling members to use one hardwired connection to exchange traffic with 175+ members on the exchange. With peering participants swapping traffic with one another through direct connections, TorIX reduces transit times for local data exchange and cuts the significant costs of Internet bandwidth. The success of TorIX is underlined by its tremendous growth, exceeding 145 Gbps as one of the largest IXs in the world. TorIX is in Cologix’s data centre at 151 Front Street, Toronto’s carrier hotel and the country’s largest telecommunications hub in the heart of Toronto. TorIX members define their own routing protocols to dictate their traffic flow, experiencing faster speeds with their data packets crossing fewer hops between the point of origin and destination. Additionally, by keeping traffic local, Canadian data avoids international networks, easing concerns related to privacy and security. Above: In Dec. 2014, TorIX traffic peaked above 140 Gbps, with average traffic hovering around 90 Gbps.

    1. Louvain School of Management (LSM) Le développement des startups en contexte d’incertitude et l’analyse de la prise de décision dans une équipe multiculturelle Mémoire à titre « Confidentiel » Mémoire-projet réalisé par Sara BARATA CARRILHO Promoteur Julie HERMANS Lecteur Malo BEGUIN Année académique 2017-2018 En vue de l’obtention du diplôme Master 120 en Sciences de gestion Chaussée de Binche, 151 - 7000 Mons, Belgique www.uclouvain.be/lsm Mémoire à titre confidentiel 2. RESUME Ayant vu le jour aux Etats, Unis, le terme « startup » n’existe pas depuis longtemps. Il ne s’est généralisé à l’international que depuis une grosse vingtaine d’année. Mais son statut de petite entreprise ne l’empêche pas de devoir faire face à son environnement interne et externe tout comme les multinationales. La recherche exploratoire suivante aura lieu d’analyser les particularités organisationnelles liées à la communication interne d’une jeune startup canadienne, intitulée Planhub, ainsi que de proposer quelques recommandations managériales pour aborder au mieux le contexte d’incertitude dans lequel elle se développe. Mots clés : contexte d’incertitude, dissidence stratégique, prise de parole, silence organisationnel, recommandations managériales. Mémoire à titre confidentiel 3. REMERCIEMENTS Je voudrais sincèrement remercier ma promotrice, Julie Hermans, qui a accepté de m’encadrer dans cette recherche exploratoire même à distance. Ses conseils et sa disponibilité m’ont été très précieux dans la réalisation de mon mémoire. Je tiens également à remercier l’équipe managériale de l’entreprise, qui a accepté de soumettre leur startup comme sujet d’étude, ainsi que le reste de l’équipe qui a pris le temps de répondre aux questionnaires individuels.
