This thesis aims to investigate the prospect of using Apache Kafka to manage data streams based on secrecy/classification level and separate these data streams in order to meet the requirement set by the secrecy/classification levels. Basalt AB has the responsibility of managing classified data for private and state actors, including the Swedish Armed Forces and other organizations. There is interest in a data-streaming solution that can securely stream large amounts of data while coordinating different data classifications and managing user access. This thesis work examines the viability of logically and physically separating producer data streams into categories based on the classification level of the data in an Apache Kafka cluster. Additionally, the thesis examines the viability of managing access control through the use of Access Control Lists. To protect against embedded attackers this thesis examines the viability of using Shamir Secret Sharing (SSS) algoritm to segment messages to on top of that use multi-factor authentication to ensure that messages cannot be read by a lone individual. The work seeks to contribute to the existing body of knowledge by improving the security, and ensuring the integrity of data through the application of detailed or granular user management of event-logs in an Apache Kafka cluster. This is of interest to organizations that require protection from both external and internal potential attackers. Our results indicate that Apache Kafka is an appropriate tool for data streaming secret data, we used a secret sharing algorithm to segment data and used Simple Authentication and Security Layer to build a multi-factor authentication system.

This dissertation examines the figure of the hand in Kafka’s literary, professional and personal writings and ties that figure to the contemporary contexts of (1) industrial labor, (2) the statistical, depersonalized perspective on the subject and its body in the modern social and insurance state, and (3) the exacerbation of these conditions during World War One. I show that hands occur in Kafka’s oeuvre wherever the subject’s identity, agency, and physical integrity is under negotiation. The first chapter analyzes Kafka’s novel Der Verschollene. It links the figure of the hand with the contexts of manual labor and industrial work practices, especially Taylorism, and shows that hands emerge when there is a tension between the worker viewed as an individual and the worker as part of the larger machinery of production. The second chapter describes Kafka’s professional background and his responsibilities at the Bohemian Workmen’s Accident Insurance Institute, thereby providing the biographical context for Kafka’s use of the hand trope. It traces the origins of social accident insurance and its inherent tension between two opposing views on the subject--the subject as impersonal part of a collective versus the subject as an individual. The chapter then provides a close reading of one of Kafka’s office writings, an illustrated report about how to prevent work accidents and in particular hand injuries. This text reveals that, even in the professional context, Kafka uses the hand as a metonymy of the threatened body, both of the worker and of its administrator. The third chapter examines the novel Der Proceß as an illustration of the abstract and anonymous worldview dominant in the insurance state, which threatens not only the blue-collar worker but also the white collar employee. Hands appear as random and arbitrary signs of an incomprehensible court system and are at the same time used by the protagonist to establish connections to the court and “grasp” his situation. In addition, the hand represents the writing and creating hand; by connecting the dimension of writing with the figure of the hand as primary political trope in Der Proceß, Kafka shows that the private and public are inseparable. The fourth chapter shows how the short but paradigmatic text “Meine zwei Hände begannen einen Kampf” draws together themes of blue-collar manual labor, white-collar responsibility and authorship by imagining a violent battle between the narrator’s left and right hand, a display of violence that should be read in the context of World War One. In his position at the insurance institute, Kafka was responsible for wounded veterans and traces of his work with amputations and prosthetics show clearly in his later texts. The dissertation will conclude with a brief analysis of “Ein Bericht Für eine Akademie” to show that the hand is the quintessentially human body part that encapsulates the violence and crises that the modern subject has to undergo in order to be a member of (human) society.

Jonas Karlssons novell Fakturan (2011) har visat sig ha flera beröringspunkter med Franz Kafkas Processen (1924). Uppsatsen visar hur dessa verk behandlar individens skuld i det moderna samhället. Karlssons novell som är skriven ca hundra år efter det att Kafka skrev Processen skildrar likväl en problematik som kanske varit gällande ända sedan marknadsekonomin först började att breda ut sig. Uppsatsen analyserar Kafkas och Karlssons verk ur ett sociologiskt perspektiv, där jag använt mig av Marx och Nietzsche som teoretiker. Bermans Allt som är fast förflyktigas har utgjort stommen ur vilken jag lutat mina påståenden om modernitetens inverkan på människan genom tiderna. Uppsatsen visar att skuldproblematiken riktad mot individen i det moderna samhället är likartad men framställs annorlunda i verken. En slutsats båda huvudkaraktärerna möjligtvis drar i berättelsernas slut, är att mänsklig kontakt och samverkan är att föredra, framför den ensamma och egoistiska vägen genom livet.
