Service Offering

It is very common today that many business models are based on offering on-line services. Profitability and efficiency of this business model relies on a secure and undisturbed Internet infrastructure. Unfortunately, services offered on Internet infrastructure, being an Open and yet untrusted network, are very often targets of Denial-of-Service and Distributed Denial-of-Service attacks. These attacks are today a serious problem for on-line services offered by many business models. Preventing or minimizing DoS and DDoS is a difficult task which could serve to many on-line service offering business models to provide quality services to their clients. The main objective of this chapter is to present the Client Puzzle mechanism as a new method designed to defend business networks and their on-line services from these attacks. By using a client puzzle protocol on the IP level, the client is forced to solve a cryptographic puzzle before it can request any operation from a server, thus creating computational efforts and delays to illegitimate attackers and minimizing their attack effects on services. In this chapter, the authors show that chained puzzle protocol reduces the network and insfrastructure overhead because the servers do not have to generate puzzles on a per-packet basis. In addition, the chapter analyzes the effectiveness and some limitations of chained puzzles method with regards to minimizing DDoS attacks and outlines a general approach for addressing the identified limitations. At the last part, the authors propose a solution based on the general principle that under attack legitimate clients should be willing to experience some degradation in their performance in order to obtain the requested service.

Ddos Attack Detection

This research proposed a new method to enhance Distributed Denial of Service (DDoS) detection attack on Software Defined Network (SDN) environment. This research utilized the OpenFlow controller of SDN for DDoS attack detection using modified method and regarding entropy value. The new method would check whether the traffic was a normal traffic or DDoS attack by measuring the randomness of the packets. This method consisted of two steps, detecting attack and checking the entropy. The result shows that the new method can reduce false positive when there is a temporary and sudden increase in normal traffic. The new method succeeds in not detecting this as a DDoS attack. Compared to previous methods, this proposed method can enhance DDoS attack detection on SDN environment.

Business Model Development

Business models have received a substantial amount of interest recently. Also, various research studies have discussed business models, especially in the context of a single company operating in mass markets. Unfortunately, these models often are not applicable for complex products or services that build on long-term knowledge about customer tastes, facilities, and skills. Especially on global markets, the asset specificity and vast geographical distances make it difficult for any single company to provide this kind of service cost-efficiently on a large scale. Instead, it calls for cooperation among multiple firms. Creation of a joint business model for a collaborative network is a necessary means by which companies can coordinate cooperation in practice. The CSOFT metamodel proposed in this chapter provides guidance for joint business model development by emphasizing customer relationship and adjustment processes needed within the network.

Plastic Industry

The plastic industry is facing increasingly growing social and political demands on plastic recycling and reuse. The resource perspective is essential for plastic production companies. Circular economy is one perspective for how industries could deal with a lack of resources today and in the future. However, there are large challenges in the reuse of plastics waste, predominantly due to concern regarding the quality of the waste material. Our paper focuses on the potential of the exchange of plastic material waste between companies in the production process before it enters into the recycling loop. In this study our aim is to investigate if an on-line marketplace is relevant for the plastic industry for this exchange, the market potential and the potential business model and requirements of the marketplace. Through interviews and benchmarking with five platform providers and two plastic manufacturing companies, we collected information on the business models of international digital platforms and plastic manufacturers concerning the exchange of reusable materials between companies. We also collected data through a survey sent out to plastic manufacturers via two industry organizations in Sweden. This paper will present the results from the study and conclude with a description of draft requirements with particular focus on direct reuse of regrind material, and a potential business model for the on-line marketplace that should be run on a commercial basis. This study shows that there are opportunities for the plastic industry to be at the forefront of a circular initiative that could also be utilized by other industries with adjustments to reflect the specific requirements of each industry.

Critical Issues

Purpose The expanding body of research on business models generally assumes that firms operate in a “transactional” context. Several recent studies suggest that the concept of business models in contexts where relationships matter, such as business markets, involves issues that the transactional microeconomic perspective is ill suited to capture. In the expanding literature on business models, the role of context in how business models emerge and evolve is a topic that appears under researched. The purpose of this paper is to review the findings of these studies and explore how “relational context” affects the emergence and evolution of business models. Design/methodology/approach The authors review the literature on business models in business markets where high-involvement relationships with customers and suppliers are common, and report a case to illustrate the critical issues involved. Findings The authors find that context where high-involvement relationships are common implies that business models are relationship specific and tend to be different across key relationships of a business; the involvement of others limits the autonomy of a single business in developing its business model; business models are continuously emergent and transient. Originality/value This study is among the few that examine the emergence and evolution of business model in business network in a longitudinal perspective. The value of the study also lies in the implications of the relationship-centric business model for management practice and research.

IoT botnets have been used to launch Distributed Denial-of-Service (DDoS) attacks affecting the Internet infrastructure. To protect the Internet from such threats and improve security mechanisms, it is critical to understand the botnets’ intents and characterize their behavior. Current malware analysis solutions, when faced with IoT, present limitations in regard to the network access containment and network traffic manipulation. In this paper, we present an approach for handling the network traffic generated by the IoT malware in an analysis environment. The proposed solution can modify the traffic at the network layer based on the actions performed by the malware. In our study case, we investigated the Mirai and Bashlite botnet families, where it was possible to block attacks to other systems, identify attacks targets, and rewrite botnets commands sent by the botnet controller to the infected devices.

Definition Of

The term ?business model' has recently attracted increased attention in the context of financial reporting and was formally introduced into the IFRS literature when IFRS 9 Financial Instruments was published in November 2009. However, IFRS 9 did not fully define the term ‘business model'. Furthermore, the literature on business models is quite diverse. It has been conducted in largely isolated fashion; therefore, no generally accepted definition of ?business model' has emerged. Therefore, a better understanding of the notion itself should be developed before further investigating its potential role within financial reporting. The aim of this paper is to highlight some of the perceived key themes and to identify other bases for grouping/organizing the literature based on business models. The contributions this paper makes to the literature are twofold: first, it complements previous review papers on business models; second, it contains a clear position on the distinction between the notions of the business model and strategy, which many authors identify as a key element in better explaining and communicating the notion of the business model. In this author's opinion, the term ‘strategy' is a dynamic and forward-looking notion, a sort of directional roadmap for future courses of action, whereas, ‘business model' is a more static notion, reflecting the conceptualisation of the company's underlying core business logic. The conclusion contains the author's thoughts on the role of the business model in financial reporting.
