This thesis addresses the research gap that exists in the area of capability maturity measurement for Security Operations Centers (SOCs). This gap is due to the fact that there is very little formal research done in this area. To address this gap in a scientific manner, a multitude of research methods is used. Primarily, a design research approach is adopted that combines guiding principles for the design of maturity models with basic design science theory and a step by step approach for executing a design science research project. This design research approach is extended with interviewing techniques, asurvey and multiple rounds of evaluation. The result of any design process is an artefact. In this case, the artefact is a self-assessment tool that can be used to establish the capability maturity level of the SOC. This tool was named the SOC-CMM (Security Operations Center Capability Maturity Model). In this tool, maturity is measured across 5 domains: business, people, process, technology and services. Capability is measured across 2 domains: technology and services. The tool provides visual output of results using web diagrams and bar charts. Additionally, an alignment with the National Institute of Standards and Technology Cyber Security Framework (NIST CSF) was also implemented by mapping services and technologies to NIST CSF phases. The tool was tested in several rounds of evaluation. The first round of evaluation was aimed at determining whether or not the setup of the tool would be viable to resolve the research problem. The second round of evaluation was a so-called laboratory experiment performed with several participants in the research. The goal of this second round was to determine whether or not the acreated artefact sufficiently addressed the research question. In this experiment it was determined that the artefact was indeed appropriate and mostly accurate, but that some optimisations were required. These optimisations were implemented and subsequently tested in a third evaluation round. The artefact was then finalised. Lastly, the SOC-CMM self-assessment tool was compared to the initial requirements and research guidelines set in this research. It was found that the SOC-CMM tool meets the quality requirements set in this research and also meets the requirements regarding design research. Thus, it can be stated that a solution was created that accurately addresses the research gap identified in this thesis. The SOC-CMM tool is available from http://www.soc-cmm.com/

NIALM (Non-Intrusive Load Monitoring) est une technologie innovante qui permet de suivre la consommation individuelle en énergie des différents appareils électriques dans un réseau électrique grâce à un seul point de mesure. Ainsi, l’installation et la maintenance du système est très simple. Cependant, le logiciel NIALM nécessite le développement d’algorithmes sophistiqués pour identifier la consommation de chaque appareil avec une bonne précision. Par conséquent, ces algorithmes complexes nécessitent une plate-forme d’exécution puissante et coûteuse. En réponse à ce problème, cette thèse propose un système NIALM innovant fonctionnant en temps réel et à faible coût. Ce système permet de dépasser certaines limites actuelles du NIALM grâce à une extraction d’informations supplémentaires sur les signatures électriques, une détection des transitions lentes et des appareils à multi-états grâce à deux nouvelles fonctions : un algorithme de détection d'événements CUSUM et une ventilation des sommes cumulées en se basant sur un algorithme génétique. La deuxième contribution importante est de proposer une méthodologie utilisant le modèle RPN (Reactive Process Network) pour développer le système NIALM dans un SoC (System on Chip) avec une accélération matérielle de type FPGA. Ce SoC permet ainsi l'exécution en parallèle dans le FPGA de processus de traitement de données avec des algorithmes complexes tout en satisfaisant les contraintes de temps. Les avantages de notre méthode sont : la capacité de développer une spécification exécutable, d’effectuer une exploration d'architecture, et d’obtenir rapidement un prototype du système NIALM à partir d’un même modèle applicatif. / In comparison to conventional smart meters, NIALM (Non-Intrusive Load Monitoring) is an innovative technology because it can monitor power usage on individual appliances in an electrical network using only one sensing node. Thus, setting up and maintaining the system is very simple because of the few of hardware elements. In contrast, the software of NIALM is often very complex and there is still the need in developing more complex algorithms to classify appliances more accurately. These complex algorithms of NIALM require to run on a powerful and expensive hardware platform. In order to overcome this problem, the first contribution of this thesis is to propose a low cost real-time innovative NIALM system to solve some limits of NIALM design by extracting more electrical signatures, detecting slow transition and multi-state appliances, and energy disaggregation in real-time. This is possible by using two new algorithms: CUSUM event detection algorithm and disaggregation based on Genetic Algorithm. Similar to complex DSP systems, a NIALM system contains both event control processes and data streaming processes. The second important contribution of this research is to propose a methodology based on RPN model (Reactive Process Network) to develop a complex NIALM system in SoC with FPGA acceleration. Such SoC allows running data streaming processes with complex algorithms and hard timing constraints in parallel in FPGA while other processes can run in processors. The advantages of our methodology are the ability to develop an executable specification to proceed to architecture exploration, and prototype the NIALM system quickly using the same application model.

Sammanfattning Bakgrund: Cancer ökar succesivt över hela världen. Kvinnors upplevelse av att leva med obotlig cancer beskrivs bland annat som kaos och förtvivlan. Cancer är ett hot mot personens hälsa och har en inverkan på livet, både kroppsligt och känslomässigt. Ju högre känsla av sammanhang desto lättare har kvinnorna att uppskatta livet som pågår runt omkring dem. Syfte: Syftet var att beskriva unga kvinnors upplevelse av att leva med obotlig cancer. Metod: En kvalitativ empirisk innehållsanalys med deduktiv design har använts i studien. Fyra stycken bloggar analyserades. KASAM användes för att strukturera upp komponenterna begriplighet, hanterbarhet och meningsfullhet. Resultat: I studien framkom det att kvinnor som drabbats av obotlig cancer upplever begriplighet om vårdpersonal informerar och bemöter dem på ett adekvat, professionellt och lyhört sätt. Bloggarna användes som ett redskap för att hantera situationen. Även nära relationer och stöd ger en positiv upplevelse för hanterbarheten. Att umgås med familj och vänner upplevs som meningsfullt. Slutsats: Känsla av sammanhang är en individuell upplevelse. Beskrivningar av upplevelser kring känsla av sammanhang ger en ökad förståelse för hur vårdpersonal kan främja begriplighet, hanterbarhet och meningsfullhet i mötet med kvinnor som drabbats av obotlig cancer. / Summary Background: Cancer increases successively over the world. Women ́s experience of living with terminal cancer is described among other things as chaos and despair. Cancer is a threat to the person’s health and has an impact on its life, physiologically as well as mentally. The higher sense of coherence the easier the women has to appreciate the life that goes on around them. Purpose: The purpose was to describe young women’s experience of living with terminal cancer. Method: A qualitative empirical content analysis design with deductive approach has been used in this study. Four blogs were analysed. SOC was structured by the three components; comprehensibility, manageability and meaningfulness. Results: The study revealed that women who suffers from terminal cancer experience intelligibility if the nursing staff informs and responds adequate, professional and in a responsive manner. The blogs were used as a tool to manage the situation. Even close relationships and support provides a positive experience for manageability. Spending time with family and friends percieved meaningfulness. Conclusion: Sense of coherence is an individual experience. Descriptions of experiences around the sense of coherence provides a better understanding for what the nursing staff can promote comprehensibility, manageability and meaningfulness, in meeting with women suffering from terminal cancer.

Under hösten 2015 har fler människor än någonsin sökt asyl i Sverige utifrån en av de svåraste flyktingsituationerna sedan andra världskriget. Socialstyrelsen visar genom jämförelser i hälsa på vikten av att människor integreras när de kommer till Sverige eftersom det påverkar deras hälsa. Kommuner i Sverige har ett stor ansvar för det integrationsarbete som sker i Sverige. Syftet med denna studie har varit att undersöka hur en mindre kommun arbetar med integration av nyanlända flyktingar. Jag har utgått från fyra frågeställningar: Vilket synsätt har kommunen på integration? Hur arbetar kommunen med integration? Vilka synsätt har de anställda i kommunen på integration? Har personalen inom kommunen kunskap om olika kulturer och finns det behov av vidareutbildning? Data till min studie har samlats in med hjälp av kvalitativa intervjuer med nio personer som arbetar med integration i den undersökta kommunen. I analysen av min studie har jag utgått från Antonovskys teori KASAM -känsla av sammanhang. Resultat av studien visar att kommunen saknar dokument för sitt integrationsarbete och att personalen har olika synsätt på integration, vilket påverkar deras sätt att arbeta med integration. Vilket leder till slutsatsen att kommunens synsätt på integration är av stor vikt då kommunens integrationsarbete utformas utifrån detta och därmed hur den nyanlände bemöts. Men där det också går att se att personalens synsätt på integration påverkar integrationsarbetet. Därför är det viktigt att kommunen arbetar med förståelsen av begreppet integration för att ge såväl politiker som personal samma utgångspunkt i sitt arbete med integration. / In autumn 2015, more people than ever have sought asylum in Sweden on the basis of one of the most difficult refugee situations since World War II. National Board shows through comparisons of health on the importance of integrating people when they come to Sweden because it affects their health. Municipalities in Sweden has a great responsibility for the integration work done in Sweden. The purpose of this study was to examine how a small municipality is working with the integration of newly arrived refugees. I have based my study on four questions: • Which approach does the municipality have on integration? • How does the municipality work with integration? • What approach has employees in the municipality on integration? • Have staff within the municipality knowledge of different cultures and is there a need for further training? The data for my study have been collected through qualitative interviews with nine people working on integration in the studied municipality. In the analysis of my study I have started from Antonovsky's theory SOC –Sence of Coherence. Results of the study show that the municipality lacks documents for its integration work and that staff have different views on integration, affecting their way of working with integration. Which leads to the conclusion that the municipality's approach to integration is of great importance when a municipal integration work formed the basis of this, and therefore how the new arrival is met. But where it is also possible to see that the staff's approach to integration affects integration efforts. Therefore it is important that the municipality is working with the understanding of the concept of integration to give both politicians and staff the same starting point in its work with integration.

Cloud computing, mobile computing, Service-Oriented Computing (SOC), and Software as a Service (SaaS) indicate that the Internet emerges to an anonymous service market where service functionality can be dynamically and ubiquitously consumed. Among functionally similar services, service consumers are interested in the consumption of the services which perform best towards their optimization preferences. The experienced performance of a service at consumer side is expressed in its non-functional properties (NFPs). Selecting the best-fit service is an individual challenge as the preferences of consumers vary. Furthermore, service markets such as the Internet are characterized by perpetual change and complexity. The complex collaboration of system environments and networks as well as expected and unexpected incidents may result in various performance experiences of a specific service at consumer side. The consideration of certain call side aspects that may distinguish such differences in the experience of NFPs is reflected in various call contexts. Service optimization based on a collaborative knowledge base of previous experiences of other, similar consumers with similar preferences is a desirable foundation. The research work described in this dissertation aims at an individually optimized selection of services considering the individual call contexts that have an impact on the performance, or NFPs in general, of a service as well as the various consumer preferences. The presented approach exploits shared measurement information about the NFP behavior of a service gained from former service calls of previous consumptions. Gaining selection/recommendation knowledge from shared experience benefits existing as well as new consumers of a service before its (initial) consumption. Our approach solely focuses on the optimization and collaborative information exchange among service consumers. It does not require the contribution of service providers or other non-consuming entities. As a result, the contribution among the participating entities also contributes to their own overall optimization benefit. With the initial focus on a single-tier optimization, we additionally provide a conceptual solution to a multi-tier optimization approach for which our recommendation framework is prepared in general. For a consumer-sided optimization, we conducted a literature study of conference papers of the last decade in order to find out what NFPs are relevant for the selection and consumption of services. The ranked results of this study represent what a broad scientific community determined to be relevant NFPs for service selection. We analyzed two general approaches for the employment of machine learning methods within our recommendation framework as part of the preparation of the actual recommendation knowledge. Addressing a future service market that has not fully developed yet and due to the fact that it seems to be impossible to be aware of the actual NFP data of different Web services at identical call contexts, a real-world validation is a challenge. In order to conduct an evaluation and also validation that can be considered to be close approximations to reality with the flexibility to challenge the machine learning approaches and methods as well as the overall recommendation approach, we used generated NFP data whose characteristics are influenced by measurement data gained from real-world Web services. For the general approach with the better evaluation results and benefits ratio, we furthermore analyzed, implemented, and validated machine learning methods that can be employed for service recommendation. Within the validation, we could achieve up to 95% of the overall achievable performance (utility) gain with a machine learning method that is focused on drift detection, which in turn, tackles the change characteristic of the Internet being an anonymous service market.
