Webassembly is a new technology to create application in a new way. Webassembly is being developed since 2017 by the worldwide web consortium (w3c). The primary task of webassembly is to improve web applications.
Today, more and more applications are being created as web applications. Web applications have some advantages - they are platform independent and even mobile platforms can run them, and no installation is needed apart from a modern web browser.
Currently, web applications are being developed in JavaScript (JS), hypertext mark-up language 5 (HTML 5), and cascading style sheets (CSS).
These technologies are not made for huge web applications, but they should not be replaced by webassembly; rather, webassembly is an extension to the currently existing technology.
The purpose of webassembly is to fix or improve the problems in web application development.
This master’s thesis reviews all of the aspects and checks whether the promises of webassembly are kept and where problems still exist.
An organized strategy to ensure the security of an organization is an information security management system. During various security crises, hazards, and breaches, this strategy aids an organization in maintaining the confidentiality, integrity, and accessibility of information. Organizations are getting ready to comply with information security management system criteria. Despite this, security concerns continue to plague ineffective controls, have poor connectivity, or cause a silo effect, which is a common cause. One of the causes is a low maturity model that is not synchronized with the organization’s business processes. For a higher level of maturity, it is best to evaluate the practices.
Different maturity models on information security and cyber security capacity, management processes, security controls, implementation level, and many more have already been developed by numerous international organizations, experts, and scholars. The present models, however, do not assess a particular organization's particular practices. The evaluation of the business process is frequently neglected because measurement requirements for models are typically more concentrated on examining specific elements. For this reason, it caused the maturity assessment to not be executed explicitly and broadly.
We developed an organizational information security maturity model, a combination of work of different maturity models currently existing. While making this model, we considered that any size or type of organization could use this model. The model considers the success elements of the information security management system when assessing the implementation's effectiveness. We employed a mixed-method strategy that included both qualitative and quantitative research. With the help of a questionnaire survey, we evaluated the previous research using a qualitative methodology. In the quantitative method, we'll figure out how mature the information security management system is now. The proposed model could be used to reduce security incidents by improving implementation gaps.
Strong security measures are required to protect sensitive data and provide ongoing service as a result of the rising reliance on online applications for a range of purposes, including e-commerce, social networking, and commercial activities. This has brought to light the necessity of strengthening security measures. There have been multiple incidents of attackers acquiring access to information, holding providers hostage with distributed denial of service attacks, or accessing the company’s network by compromising the application.
The Bundesamt für Sicherheit in der Informationstechnik (BSI) has published a comprehensive set of information security principles and standards that can be utilized as a solid basis for the development of a web application that is secure.
The purpose of this thesis is to build and construct a secure web application that adheres to the requirements established in the BSI guideline. This will be done in order to answer the growing concerns regarding the security of web applications. We will also evaluate the efficacy of the recommendations by conducting security tests on the prototype application and determining whether or not the vulnerabilities that are connected with a web application that is not secure have been mitigated.
The embedding of microwave devices is treated by applying the finite-difference method to three-dimensional shielded structures. A program package was developed to evaluate electromagnetic fields inside arbitrary transmission-line connecting structures and to compute the scattering matrix. The air bridge, the transition through a wall, and the bond wire are examined as interconnecting structures. Detailed results are given and discussed regarding the fundamental behavior of embedding.
The rapid pace of innovation and technological advancements has led to the emergence of start-up companies in various sectors.

This master thesis explores the role of Business Intelligence in start-up companies. The study aims to investigate the use of BI in start-up companies, the drivers and the inhibitors for its adoption and their relationship with price. The research conducted for this thesis involves a review of relevant literature on Business Intelligence, start-up companies, and related topics. The study also includes structured survey with entrepreneurs, start-up company executives, and BI experts to gain data for a quantitative analysis of the topic.
The thesis aims to contribute to the existing body of knowledge on Business Intelligence and its role in start-up companies. The research conducted for this thesis can be of value to start-up entrepreneurs, investors, and other stakeholders who seek to improve their understanding of the benefits and challenges of implementing BI in start-up companies.
The primary objective of this thesis is to examine the lean accounting transformation, which involves applying lean management principles to the accounting domain. In recent years, various sectors, including manufacturing, healthcare, and services, have experienced success with lean management practices. Nevertheless, the implementation of lean accounting within financial management has not been as extensively explored. This research aims to bridge that gap by scrutinizing the benefits and potential drawbacks of adopting lean accounting practices in business operations.
This research uses a combination of qualitative techniques and an extensive literature review to better understand the present subject matter. By describing the ideas of lean management and standard accounting and highlighting the fundamental distinctions between the two systems, the literature study lays a theoretical framework. The case studies illustrate the benefits of adopting lean accounting processes with real-world examples of firms that have made the transition effectively.
In the quantitative analysis of lean accounting's impact, both financial and operational factors are examined extensively. The results indicate that companies embracing lean accounting practices experience significant improvements in productivity, cost reduction, and decisionmaking quality. By highlighting the potential gains to be made by incorporating lean techniques into accounting procedures, this study adds to the current body of information on lean management. The findings offer practical implications for accounting professionals, business leaders, and policymakers interested in leveraging lean accounting to drive organizational performance improvement. The thesis finishes with suggestions for further study in this area, lean accounting.

The coronavirus affects the strongly export-oriented Swiss economy in a situation where political and economic developments are already making the cross-border exchange of goods and services difficult. For this reason, the question arises of how Switzerland can maintain or strengthen its position in global competition in the export business during an unprecedented period of crisis such as the current one.
In order to find an answer to this question, this paper critically examines the existing government support measures for Swiss exporters in times of COVID-19. The fact that Switzerland has so far not taken any specific support measures for exporters raises the actual research question of whether there is a specific necessity and demand for a special export promotion. To answer this research question, various expert opinions are compared and overall conclusions are drawn. By rapidly introducing and adapting the already existing instruments – liquidity assistance and an expansion of short-time work benefits – the federal government was able to ensure the survival of many companies. According to the authors of this paper, this focus of government support in times of crisis is just right for a small national economy in the short term and therefore preferable to a specific support of exporters. Nevertheless, given the high relative importance of foreign trade for Switzerland’s overall economic performance, there can be no recovery of national economy without a recovery of foreign trade.

This essay deals with the Spanish economy and especially with the Spanish governmental measures for SME exporters in times of COVID-19. The focus was set on SMEs, as they are an essential part of trade for the government and are particularly affected by the pandemic. Since the financial crisis, the Spanish economy has become highly diversified, with a greater focus on exports. Competitiveness, productivity and efficiency have increased significantly. The Spanish government measures largely affect the areas liquidity and financing, taxes and protection of the employment. One of the most important measures is the 100-billion-euro credit line and the policies on unemployment. The Spanish government is dependent on further aid packages and is criticized for the measures.
The COVID-19 pandemic has led to an economic downturn in the Slovak Republic. To bridge corporate liquidity problems the Slovakian Government has introduced several support measures.

As the automotive industry plays a leading role in Slovakia, the research conducted is oriented towards the financing phases, a typical automotive exporter is undergoing. As a result of the research, bridging loans and government grants were identified as the most important measures. Additionally, tendencies towards political recommendations for action were identified. The research explored, that the Slovakian Government should focus on meeting the short-term liquidity needs, boosting exports and promoting innovation as well as considering a support package for the automotive industry.
As cyber threats continue to evolve, it is becoming increasingly important for organizations to have a Security Operations Center (SOC) in place to effectively defend against them. However, building and maintaining a SOC can be a daunting task without clear guidelines, policies, and procedures in place. Additionally, most current SOC solutions used by organizations are outdated, lack key features and integrations, and are expensive to maintain and upgrade. Moreover, proprietary solutions can lead to vendor lock-in, making it difficult to switch to a different solution in the future.
To address these challenges, this thesis proposes a comprehensive SOC framework and an open-source SOC solution that provides organizations with a flexible and cost-effective way to defend against modern cyber threats. The research methodology involved conducting a thorough literature review of existing literature and research on building and maintaining a SOC, including using SOC as a service. The data collected from the literature review was analyzed to identify common themes, challenges, and best practices for building and maintaining a SOC.
Based on the data collected, a comprehensive framework for building and maintaining a SOC was developed. The framework addresses essential areas such as the scope and purpose of the SOC, governance and leadership, staffing and skills, technologies and tools, processes and procedures, service level agreements (SLAs), and evaluation and measurement. This framework provides organizations with the necessary guidance and resources to establish and effectively operate a SOC, as well as a reference for evaluating the service provided by SOC service providers.
In addition to the SOC framework, a modern open-source SOC solution was developed, which emphasizes several key measures to help organizations defend against modern cyber threats. These measures include real-time, actionable threat intelligence, rapid and effective incident response, continuous security monitoring and alerting, automation, integration, and customization. The use of open-source technologies and a modular architecture makes the solution cost-effective, allowing organizations to scale it up or down as needed.
Overall, the proposed SOC framework and open-source SOC solution provide organizations with a comprehensive and systematic approach for building and maintaining a SOC that is aligned with the needs and objectives of the organization. The open-source SOC solution provides a flexible and cost-effective way to defend against modern cyber threats, helping organizations to effectively operate their SOC and reduce their risk of security incidents and breaches.

Risk-based Cybermaturity Assessment Model - Protecting the company against ransomware attacks
(2023)
Ransomware has become one of the most catastrophic attacks in the previous decade, hurting businesses of all sorts worldwide. So, no organization is safe, and most companies are reviewing their ransomware defensive solutions to avoid business and operational hazards. IT departments are using cybersecurity maturity assessment frameworks like CMMC, C2M2, CMMI, NIST, CIS, CPP, and others to analyze organization security capabilities. In addition to maturity assessment models for the process layer and human pillar, there are much research on the analysis, identification, and defense of cyber threats in product/software layers that propose state-of-the-art approaches.
This motivates a comprehensive ransomware cyber security solution. Then, a crucial question arises: “How companies can measure the security maturity of controls in a specific danger for example for Ransomware attack?” Several studies and frameworks addressed this subject.
Complexity of understanding the ransomware attack, Lack of comprehensive ransomware defense solutions and Lack of cybermaturity assessment model for ransomware defense solutions are different aspects of problem statement in this study. By considering the most important limitations to developing a ransomware defense cybermaturity assessment method, this study developed a cybermaturity assessment methodology and implemented a Toolkit to conduct cyber security self-assessment specifically for ransomware attack to provide a clearer vision for enterprises to analyze the security maturity of controls regardless of industry or size.
The current thesis conducts the study on the integration of digitalization techniques aimed at improving energy supply efficiency in off-grid energy systems. The primary objective is to fortify the security of energy supply in remote areas, particularly in instances of adverse weather conditions, unanticipated changes in load and fluctuations in the performance of renewable energy systems. This objective is to be achieved through the implementation of a smart load management strategy in stand-alone photovoltaic systems (SAPVS). This strategy involves deployment of forecasting algorithms on an edge device that operates with limited processing resources in an environment characterized for the lack of internet connection. The edge device is designed to interact with a smart home gateway that prioritizes, and schedules smart appliances based on the forecasted state of charge (SOC) in the 36-hours ahead of the SAPVS operation (the implementation of the loads schedule deployed on the Home Assistant device is out of the scope of the tasks implemented for this project).
The edge device, developed using a Raspberry Pi 3B+, was specifically intended for being implemented along with a SAPVS, in remote areas such as health stations in Africa and tropical islands, providing communities with a reliable source of electrical energy. The deployment of the strategy was carried out in four phases. The first phase involved the implementation of an Extraction-Transformation-Load (ETL) pipeline, where data was gathered from various heterogeneous hardware sources of an implemented test system that served as the enabler and testbench of this research, this test stand is composed of power electronics components such as an inverter, a MPPT solar charge controller, a smart meter, and a BOS LiFePo4 battery prototype. In the transformation stage, a data model was developed to identify the most critical parameters of the energy system, and to eliminate outliers and null values. In the load stage, a local SQL database was established for saving and structuring the data gathered and to ensure high-quality data with defined units and casting.
The second phase involved data analysis to identify the relevant features and potential exogenous variables for the forecasting model to implement. In the third phase, an Auto Regressive Moving Average (ARMA) model with two selected exogenous variables was implemented to forecast the AC load consumption profile for the 36- hours ahead of the off-grid system operation. The final phase involved the information exchange with the Home Assistant device, by transferring to it from the edge device the battery SOC present value and the predicted 36-hour ahead AC load profile information for prioritization and scheduling of loads; this through an MQTT interface.
The outcome of the experiment was a successful deployment of a data engineering and data forecasting approach that enabled data quality strategy implementation, local database storage, and forecasting algorithms on a processing and internet-constrained edge device. The interface with a home assistant implementation resulted in the successful execution of smart load management endeavors in an off-grid system, thereby enhancing the energy security of supply and contributing to the advancement of data-driven strategies in the rural electrification sector.
This thesis emphasizes the significance of digitalization strategies in smart SAPVS and highlights the potential of edge computing solutions in achieving seamless energy management in smart homes.
Self-sufficient enzymes belong to the cytochrome P450 (CYP) group and are known for their superior hydroxylation catalytic activity. In the pursuit of identifying new pesticides to combat antimicrobial-resistant pathogens, we employed BM3 wild type (BM3-WT), the fastest monohydroxylating CYP, along with its seven homologs, to investigate the production of potential hydroxylated derivatives from the established pesticide, 4-oxocrotonic acid using high-pressure liquid chromatography (HPLC) method. Following the recombinant production of BM3-WT and three other homologs in E. coli, and their subsequent purification using Immobilized Metal Affinity Chromatography (IMAC), a novel enzyme assay approach was developed as a substitute for the carbon monoxide (CO) assay. This new method relied on the measurement of NADPH consumption at 340 nm by BM3-WT for palmitic acid. Leveraging this established technique, we explored the substrate specificity of BM3-WT and its homologs not only on palmitic acid but also on other structurally similar compounds, including 4-oxocrotonic acid. The results obtained from the established NADPH assay indicate that all tested enzymes displayed greater catalytic activity on 4-oxocrotonic acid in comparison to other substrates with similar structures. However, the impact of BM3-WT and its homologs on 4-oxocrotonic acid varied in terms of product specificity. Enzymes such as Poh, Trr and Bas-CYP D exhibited specificity in producing solely monohydroxylated products, while others tended to yield dehydroxylated and ketol metabolites.

In the beginning, there was an idea: the reconstruction of the first "Iron Hand" of the Franconian imperial knight Götz von Berlichingen (1480–1562). We found that with this historical prosthesis, simple actions for daily use, such as holding a wine glass, a mobile phone, a bicycle handlebar grip, a horse’s reins, or some grapes, are possible without effort. Controlling this passive artificial hand, however, is based on the help of a healthy second hand.
