Abstract. The vision of self-aware, self-healing, and self-managing Information Technology (IT) systems has remained elusive till recently. Recent advancements in Cloud computing, Natural Language Processing (NLP), Machine Learning (ML), and Artificial Intelligence (AI) in general, i. are all making it possible to realize this vision now. AI can optimize IT operations management processes by increasing application availability, predicting and detecting problems early, reducing the time it takes to resolve problems, proactively avoiding problems, and optimizing the resources and cost of running business applications on hybrid Clouds. In this talk, I will discuss the opportunity for AI to optimize IT Operations Management. I will describe how semi-structured application and infrastructure logs can be analyzed to predict anomalies early, how entities can be extracted and linked from logs, alerts and events to reduce alert noise for IT operations admins, how NLP can be put to use on unstructured content in prior incident tickets to extract next-best-action recommendations to resolve problems, and how deployment change request descriptions can be analyzed in combination with past incident root cause information to predict risks of deployment changes to prevent issues from happening in the first place.

Bio. Dr. Galina D. Pildush has been active in computer networking and cyber security industry for more than twenty years. She holds PhD in Organization and Management, specializing in IT, MSc and BSc, both in Computer Science. Over ten years ago, Galina’s passion had expanded into Mobile Network Operator (MNO) infrastructure protection, cloud security, and virtualization. Throughout the years, Galina held various engineering roles, product management & architecture, and strategy & planning with various high-tech companies. Galina is being an active industry standards contributor (3GPP, IETF, ETSI), an author of computer networking books and articles, a blogger, and a frequent speaker/panelist at various security conferences, evangelizing MNOs infrastructure security and services. At Palo Alto Networks, Galina’s current role is World Wide Consulting Engineering, focusing on MNO infrastructures’ security and services.

Abstract. New technologies, or even old ones, create new opportunities for cybercriminals. The attackers don’t have to be sophisticated to make an impact. Just think of Mirai. Is it completely eradicated or is it still mingling out there in the wild, perhaps in another form factor? Can legacy security approaches keep up with the new technologies, the speeds and feeds offered by 5G, soon to be 6G, protecting humans, things, data, and preventing loss of lives? This presentation covers the latest findings “in the wild”, explaining the attackers’ kill chain, the versatility of threat vectors, especially in the Service Provider space, threats’ impact on our daily lives, ranging from consumers to enterprises and service providers. It will identify the ever-increasing threat vectors from IoTs and smart hand-held devices, security risks, security requirements, and the security mechanisms that would result in preventative Zero Trust security posture. It will go into details on how preventative security can be architected holistically. With increased threat vectors come responsibilities. As cyberthreat impact on our daily lives cannot be looked at in isolation, we must transform the challenges into opportunities. Which opportunities are those? Is it enough just to be diligent in avoiding opening fishing emails, for example, or is there more to it?



Kostas Kontogiannis, Western University: Extracting Microservice Dependencies

Bio. Kostas is a Professor and Western Research Chair in Software Engineering for Cyber-Physical Systems at the Department of Computer Science at Western University. Kostas received a B.Sc. degree in Mathematics from the University of Patras, Greece, a M.Sc. degree in Computer Science from Katholieke Universiteit Leuven, Belgium, and a Ph.D. degree in Computer Science from McGill University, Canada.

Abstract. The use of virtualization technologies and cloud computing made possible the “on-demand” provision of resources and functionality of large software systems. Microservices architecture advocates the use of granular components (i.e. microservices) each one offering specific operations, deployed “on-demand” on virtualized containers. Examples of microservice architectures include the processing of data stemming from many IoT devices, applications related to agent-computing, and enterprise applications that are dynamically adapted to meet variable load profiles. Deployed microservices can interact with other microservices within the same container or between containers using standard inter-process communication protocols and standard service-oriented computing paradigms (REST, RPC etc.). However, in such a dynamic and complex environment, small changes in the implementation of one microservice may have significant effects (i.e. failures, policy violations) in other microservices. Consequently, this new architectural paradigm has a major effect on the way we develop such software systems and enforces new software development models. One such model is referred to a “Continuous Software Engineering” and focuses on a) making small incremental changes only; b) continuously (and if possible automatically) evaluating the quality and interactions of the system’s components when these changes are made and c) release small and release often. In this talk, we first discuss the topic of Continuous Software Engineering and in particular the issues of Continuous Integration, Continuous Deployment (CI/CD) and second, we present a technique to extract call-related and data transfer-related dependencies in microservice architectures from run-time logs, forming thus a dependency graph which constitutes a major step towards the identification of functional and non-functional requirements violations in microservice architectures.
