SACHI Seminar: Mike Hazas, Lancaster University

 

Title:  Internet services, energy demand and everyday life

Abstract:  Over the last decade, the growth in data traffic across the Internet has been dramatic, and forecasts predict a similar ongoing pattern. Since this is associated with remarkable electricity consumption (about 10% globally, and rising), such a trend is significant to efforts to reduce carbon emissions.  This calls for careful attention to the nature of these trends, as levels of Internet electricity demand become ever more directly and explicitly problematic.  Based on a host of prior literature and two field studies, this talk explores what we know about the energy intensity of digital stuff, and the growth of Internet traffic.  It considers how such traffic can be attributed to different Internet services like video streaming or social networking, and how these link to everyday practices which draw upon and generate data online.

Biography:  Dr Mike Hazas is a Senior Lecturer at Lancaster University, who works at the confluence of human-computer interaction and social science. His research combines qualitative and quantitative methods to understand everyday practices and technologies, how they can be related to carbon emissions and energy demand, and more sustainable trajectories. Mike co-directs the multidisciplinary Socio-Digital Sustainability group at Lancaster, and has served as a chair of the CHI Specific Application Areas subcommittee for the last three years.  Mike is a co-investigator in the DEMAND Centre (EPSRC, 2013-2018) which is concerned with the relationship of social practices and energy demand.

SRG Seminar: New Network Functionality using ILNPv6 and DNS by Khawar Shehzad

This research deals with the introduction of a new network functionality based on Identifier-Locator Network Protocol version 6 (ILNPv6), and Domain Name System (DNS). The chosen area of concern is security and specifically mitigation of Distributed Denial of Service (DDoS). The functionality proposed and tested deals with the issues of vulnerability testing, probing, and scanning which directly lead to a successful DDoS attack. The solutions presented can be used as a reactive measure to these security issues. The DDoS is chosen because in recent years DDoS have become the most common and hard to defend attacks. These attacks are on the availability of system/site. There are multiple solutions in the literature but no one solution is based on ILNPv6, and are complex in nature. Similarly, the solutions in literature either require modification in the providers’ networks or they are complex if they are only site-based solutions. Most of these solutions are based on IPv6 protocol and they do not use the concept of naming, as proposed by ILNPv6.

The prime objectives of this research are:

  • to defend against DDoS attacks with the use of naming and DNS
  • to increase the attacker’s effort, reduce vulnerability testing, and random probing by attackers
  • to practically demonstrate the effectiveness of the ILNPv6-based solution for security

Best Final Year Student at Lovelace 2017

We are delighted to congratulate Iveta Dulova, who attended the 10th BCSWomen  Lovelace Colloquium, and walked away with the prize for “Best Final Year Student”. Iveta’s poster, titled “SensorCube: An end-to-end framework for conducting research via mobile sensing“, was based on her final year project supervised by Dr Juan Ye.

The event was held at Aberystwyth University on April 12, 2017. Also attending from St Andrews were Chloe Collins, competing in the second year category with the poster “Pedal to the metal – the role of technology in transportation” and Laura Brewis with her poster “What percentage of solitaire games are actually winnable?”.

It showed great commitment for these three students to undertake the lengthy trip at a busy time of semester. Like St Andrews, Aberystwyth, is a beautiful small seaside town with an excellent Computer Science department.  Iveta took a couple of photos showing off the beach and the campus.

SRG Seminar: Investigation of Virtual Network Isolation Security in Cloud Computing Using Penetration Testing by Haifa Al Nasseri

Software Defined Networking (SDN) or Virtual Networks (VNs) are required for cloud tenants to leverage demands. However, multi-tenancy can be compromised without proper isolation. Much research has been conducted into VN Isolation; many researchers are not tackling security aspects or checking if their isolation evaluation is complete. Therefore, data leakage is a major security concern in the cloud in general.

This research uses an OpenStack VN and OpenStack Tenant Network to test multi-tenancy features. We are evaluating the relationship between isolation methods used in cloud VN and the amount of data being leaked through using penetration tests. These tests will be used to identify the vulnerabilities causing cloud VN data leakage and to investigate how the vulnerabilities, and the leaked data, can compromise the tenant Virtual Networks.

Workshop on Considering Technology through a Philosophical Lens

Technology fundamentally shapes our communication, relationships, and access to information. It also evolves through our interaction with it. Dialoguing across disciplines can facilitate an understanding of these complex and reciprocal relationships and fuel reflection and innovation.

This hands-on, participant-driven and experimental workshop will start a discussion of what can come from considering technology through a philosophical lens. Through discussions and hands-on design activities, it will provide an introduction to and reflection on questions at the intersection of computer science and philosophy, such as:

  • How have philosophy and technology shaped each other in the past?
  • How can philosophical ideas and methods guide research in Computer Science?
  • How can thinking through technology help Humanities researchers discover relevance and articulate impact in their research?

Engaging these questions can provide participants an entry-point into exploring these themes in the context of their own research.

This workshop is aimed at researchers from computer science who are curious about philosophy and how to leverage it to inform technically oriented research questions and designing for innovation. It is also aimed at researchers in the arts & humanities, social sciences, and philosophy who are curious about current research questions and approaches in computer science and how questions of technology can stimulate philosophical thought and research.

Attending the workshop is free but please register by emailing Nick Daly: nd40[at]st-andrews.ac.uk

Organisers: Nick Daly (School of Modern Languages) and Uta Hinrichs (School of Computer Science)

Alex Bain completes 2017 London Marathon

Congratulations to School Manager Alex Bain, who completed the London Marathon again this year, raising funds for Guide Dogs. Alex, runner no 40807 is pictured below with his finisher’s medal. Donations to recognise his achievement and the training involved, can be made via his Justgiving page. Read more about his fundraising on KingdomFM.

Junior Honours: Software Team Project 2017

Earlier today our Junior Honours students presented their Team Projects. The projects involve substantial team based software engineering and rely heavily on collaborative development. There are many aspects of software and professional development along with considerable inter-team and intra-team collaborations. This year the students were asked to develop a version of the Settlers of Catan with AI players. They were further asked to make their games interoperate so one teams AI or human player might play on another teams game and board.

The teams demonstrated lots of creativity with the use of software tools, approaches to AI, use of domain specific languages, remote services, games environments, graphics development, collaborative frameworks and many tools for software engineering project development. Thanks to all the students, supervisors and coordinators for their hard work this year.

We wish all our junior honours students success with their forthcoming exams and we look forward to seeing them again for their senior honours year in September.
