    Students contribute to research and a safer digital environment

    Our smartphones constantly leak personal information, and few of us know how this information is used. Computer Science students at Karlstad University have developed Kaudroid – a tool for investigating how apps use permissions to collect user data.

    85 percent of people in Sweden owns a smartphone
    According to the annual report on “Swedes and the Internet,” 85% of people in Sweden over the age of 12 had a smartphone in 2017. Many of the apps we install on these smartphones require permission to access certain data and functions. Yet it is often unclear how apps then use these permissions. As citizens of the digital world, we need to be able to feel certain that the data we produce are used securely.

    Open source – From geeky to the best

    Fifteen years ago, open source developers were considered geeky. Today, on the contrary, these are the most sought after developers. Redpill Linpro, a company only working with products based on open source code, hosted the last SNITS lunch of the year on 5 December, with the theme “Kickstarting your career with open source”.

    Software developed from source code that is open to everyone to use, change, develop and distribute is known as open source. The opposite is licenced source codes, or so-called proprietary software.

    “Fifteen years ago, the established software companies laughed at open source,” says Fredrik Svensson, regional manager and one of the founders of Redpill Linpro. “Today it is a well-established term in the branch and many of the large digital companies, like Spotify, Google, Twitter and Facebook, use open source-based software.”

    International network on privacy and usability research for doctoral students

    The Internet and our ever increasingly digital world hold many advantages, but these come at a price – our privacy. Through an international network of doctoral students, the Privacy&Us project aims at finding solutions to give citizens the benefits of digitalisation, while still protecting their privacy.

    The projects involves thirteen creative, entrepreneurial and innovative doctoral students whose projects focus on online privacy and usability. Privacy&Us is a collaborative project that includes a consortium of nine universities and companies from Sweden, Austria, Germany, the UK and Israel. The project further involves seven partners. Each doctoral student is based at one of the project participants, but during three exchange periods they conduct their research at other project participants or partners.

    Platform for testing mobile broadband networks

    There is a great need to test the stability and performance of mobile broadband networks. A transnational European platform for testing mobile broadband networks has been developed by the MONROE (Measuring Mobile Broadband Networks in Europe) project. The platform is now open and accessible to external actors. The opening was announced during a conference on Internet measurements.

    In 2015, the MONROE project commenced with the aim of designing, building and running an open platform for conducting live tests on mobile broadband networks. As one primary target, the platform can be used to identify key parameters that influence performance of mobile broadband networks, thereby facilitating reliable, realistic and meaningful assessment and evaluation of network performance.

    Firewalls – a security risk?

    Protecting business networks is getting more and more important. But how well do firewalls actually do in protecting sensitive and confidential information? Configuring firewalls can be complicated, even for system administrators, and that can lead to security risks and opportunities for intruders.

    Today, almost every company and their systems are connected to the Internet, thereby they are exposed to a huge number of threats. For example, it can lead to confidential data theft, service disruption and financial losses. One of the most important aspects to protect the network and systems connected to it, is to use correctly configured firewalls in order to restrain intruders by controlling the incoming and outgoing traffic.

    African study visit for the development of smart grids

    Computer Science at Karlstad University has a lot of expertise in online privacy and security, and therefore researchers and teachers from South Africa and Tanzania are visiting the department. Their visit is based on the need to improve energy supply in Africa and to develop training on smart grids.

    Energy supply is an important sustainability and development issue in Africa. It is particularly important to facilitate the development of green energy and to use natural resources like sunlight and wind. Smart grids are important factors in this development.

    “Researchers and teachers from four different African universities have visited us for around four weeks. Together we work on developing training on smart grids at these four institutions,” says Hans Hedbom, lecturer in Computer Science at Karlstad University.
