Description
The biohacker movement is an important and modern form of activism. This study broadly examines how positive-activist-oriented biohackers emerge, organize, and respond to social crises. Despite growing public awareness, few studies have examined biohacking's influence on prevailing notions of organizing and medicine in-context. Therefore, this study examines biohacking in the context of the 2016 EpiPen price-gouging crisis, and explores how biohackers communicatively attempted to constitute counter-narratives and counter-logics about medical access and price through do-it-yourself (DIY) medical device alternatives. Discourse tracing and critical case study analysis are useful methodological frameworks for mapping the historical discursive and material logics that led to the EpiPen pricing crisis, including the medicalization of allergy, the advancement of drug-device combination technologies, and role of public health policy, and pharmaceutical marketing tactics. Findings suggest two new interpretations for how non-traditional forms of organizing facilitate new modes of resistance in times of institutional crisis. First, the study considers the concept of "pop-up maktivism" to conceptualize activism as a type of connective activity rather than collective organizing. Second, findings illustrate how activities such as participation and co-production can function as meaningful forms of institutional resistance within dominant discourses. This study proposes “mirrored materiality” to describe how biohackers deploy certain dominant logics to contest others. Lastly, implications for contributions to the conceptual frameworks of biopower, sociomateriality, and alternative organizing are discussed.

Description
The ease of programmability in Software-Defined Networking (SDN) makes it a great platform for implementation of various initiatives that involve application deployment, dynamic topology changes, and decentralized network management in a multi-tenant data center environment. However, implementing security solutions in such an environment is fraught with policy conflicts and consistency issues with the hardness of this problem being affected by the distribution scheme for the SDN controllers.
In this dissertation, a formalism for flow rule conflicts in SDN environments is introduced. This formalism is realized in Brew, a security policy analysis framework implemented on an OpenDaylight SDN controller. Brew has comprehensive conflict detection and resolution modules to ensure that no two flow rules in a distributed SDN-based cloud environment have conflicts at any layer; thereby assuring consistent conflict-free security policy implementation and preventing information leakage. Techniques for global prioritization of flow rules in a decentralized environment are presented, using which all SDN flow rule conflicts are recognized and classified. Strategies for unassisted resolution of these conflicts are also detailed. Alternately, if administrator input is desired to resolve conflicts, a novel visualization scheme is implemented to help the administrators view the conflicts in an aesthetic manner. The correctness, feasibility and scalability of the Brew proof-of-concept prototype is demonstrated. Flow rule conflict avoidance using a buddy address space management technique is studied as an alternate to conflict detection and resolution in highly dynamic cloud systems attempting to implement an SDN-based Moving Target Defense (MTD) countermeasures.
