  • Consensus mechanisms and information security technologies
    • Abstract: Publication date: Available online 19 June 2019Source: Advances in ComputersAuthor(s): Peng Zhang, Douglas C. Schmidt, Jules White, Abhishek Dubey Distributed Ledger Technology (DLT) helps maintain and distribute predefined types of information and data in a decentralized manner. It removes the reliance on a third-party intermediary, while securing information exchange and creating shared truth via transaction records that are hard to tamper with. The successful operation of DLT stems largely from two computer science technologies: consensus mechanisms and information security protocols. Consensus mechanisms, such as Proof of Work (PoW) and Raft, ensure that the DLT network collectively agrees on contents stored in the ledger. Information security protocols, such as encryption and hashing, protect data integrity and safeguard data against unauthorized access.The most popular incarnation of DLT has been used in cryptocurrencies, such as Bitcoin and Ethereum, through public blockchains, which requires the application of more robust consensus protocols across the entire network. An example is PoW, which has been employed by Bitcoin, but which is also highly energy inefficient. Other forms of DLT include consortium and private blockchains where networks are configured within federated entities or a single organization, in which case less energy intensive consensus protocols (such as Raft) would suffice. This chapter surveys existing consensus mechanisms and information security technologies used in DLT.
       
  • A comprehensive survey of issues in solid state drives
    • Abstract: Publication date: Available online 7 May 2019Source: Advances in ComputersAuthor(s): Youngbin Jin, Ben Lee Flash memory-based solid state drives (SSDs) have become ubiquitous in modern computing systems, such as high-performance servers, workstation, desktops, and laptops, due to their performance and density. The architecture of SSDs has evolved to exploit the advantages of flash memories and at the same time conceal their shortcomings. SSD concurrency techniques such as channel striping, flash-chip pipelining, die interleaving, and plane sharing utilize the available parallelism of flash memories, while the flash translation layer (FTL) operations minimize the latency overhead of flash memories. This chapter provides a comprehensive survey of SSD topics that span across from the physical properties of a flash memory cell to the architecture of SSDs. The FTL-related topics are discussed in the context of inter-related system-level operations, which include address mapping, garbage collection, wear leveling, bad block management, SSD concurrency techniques, and page allocation strategies. This chapter also surveys recent research efforts on SSDs.
       
  • Toward realizing self-protecting healthcare information systems: Design
           and security challenges
    • Abstract: Publication date: Available online 26 March 2019Source: Advances in ComputersAuthor(s): Qian Chen This book chapter reviews the history of Healthcare Information Systems (HISs), discusses recent cyber security threats affecting HISs, and then introduces the autonomic computing concept and applies the concept to design self-protecting HISs (SPHISs) that can defend themselves against cyber intrusions with little or no human intervention. To realize such SPHISs, we first study security vulnerabilities of the HIS network, communication links and protocols. Based on these vulnerabilities, the component design of a SPHIS is presented. We propose that a SPHIS should contain monitoring systems, early estimation modules, intrusion detection, network forensics analysis devices and intrusion response systems. Finally, existing self-protecting approaches for HIS, enterprise systems and industrial control systems are demonstrated in detail. This chapter provides an innovated design of an autonomic security management system that could reduce IT professional's management burdens while enhancing the security posture of their HISs.
       
  • Revisiting VM performance and optimization challenges for big data
    • Abstract: Publication date: Available online 18 March 2019Source: Advances in ComputersAuthor(s): Muhammad Ziad Nayyer, Imran Raza, Syed Asad Hussain The concept of virtualization in cloud computing aims to maximize resource utilization and minimize cost by deploying multiple Virtual Machines (VMs) on a single physical server sharing resources such as CPU, Cache, I/O, and Memory. The sharing of these resources can cause severe performance degradation, thus requiring VM migration techniques for performance enhancement. The introduction of big data has made the performance enhancement more challenging due to extensive volume, velocity, variety, variability, and veracity of data. The existing VM performance and optimization challenges need to be optimized for big data use cases. This chapter presents big data triggered VM performance challenges focusing big data applications and storage migration in cloud computing. State of the art VM migration techniques are evaluated against challenges posed by big data to outline possible solutions and research challenges.
       
  • SSIM and ML based QoE enhancement approach in SDN context
    • Abstract: Publication date: Available online 15 March 2019Source: Advances in ComputersAuthor(s): Asma Ben Letaifa Today, video streaming rose above all other traffic types over the internet. While providing this service with a high quality is the most challenging task, researchers are trying to solve the challenge by giving a more efficient network where congestion, broadband limitations and unsatisfied users are limited. In new multimedia based networks, new challenges move from technology-oriented services to user-oriented services which prove the importance of QoE. Service providers' growth depends nowadays not only on QoS parameters but also on clients' feeling and expectation. That is why; service providers must measure received QoE and this becomes a challenge regarding the evaluation of users' feeling. For users, qualitative perception differs from one user to another and service providers affront difficulties to transform the qualitative values into the quantitative one. The QoE evaluation needs more sophisticated methods to describe the real expectation of users. New multimedia applications provide at any user locations media who are sharing video, and communicating together in virtual network. These applications require providing the best possible QoE to consumers. When it comes to us, we present in this paper a machine learning approach combined with adaptive coding in order to provide a better QoE for video streaming services. This solution will be established using SDN architecture. We can justify this choice because we need a centralized architecture, where the totality of the network is known, to predict its status. So, we will implement a machine learning algorithm in the controller: this algorithm, called ML-based SSIM, will calculate approximately the quality needed for a video to be streamed. Finally, the quality found by the ML-based SSIM Algorithm will be combined with the network situation to choose the right coding. First part of the paper deals with an introduction of QoE requirement, metrics and protocols used especially in streaming services, then we give a complete study around Machine learning algorithms and other fields used in literature to enhance QoE. We define in this paper, at first, QoS and QoE, then the serving environment such as mobile cloud computing and software Defined Network (SDN). Then, we give both objective and subjective metrics, expose mathematical approaches used in modeling, predicting and evaluating QoE. Second, we expose the SSIM approach and explain how our proposed one is based on. The last part of the paper deals with experiments: we describe SDN environment deployment, describe scenarios and finally simulate on SDN emulator some topologies to demonstrate the impact of SDN components helping QoE measurement. At the end, we give the results and values. We highlight the future of our proposition.
       
  • Integrated platforms for blockchain enablement
    • Abstract: Publication date: Available online 7 March 2019Source: Advances in ComputersAuthor(s): Md Sadek Ferdous, Kamanashis Biswas, Mohammad Jabed Morshed Chowdhury, Niaz Chowdhury, Vallipuram Muthukkumarasamy The Internet of Things (IoT) is experiencing an exponential growth in a wide variety of use-cases in multiple application domains, such as healthcare, agriculture, smart cities, smart homes, supply chain, and so on. To harness its full potential, it must be based upon a resilient network architecture with strong support for security, privacy, and trust. Most of these issues still remain to be addressed carefully for the IoT systems. Blockchain technology has recently emerged as a breakthrough technology with the potential to deliver some valuable properties such as resiliency, support for integrity, anonymity, decentralization, and autonomous control. A number of blockchain platforms are proposed that may be suitable for different use-cases including IoT applications. In such, the possibility to integrate the IoT and blockchain technology is seen as a potential solution to address some crucial issues. However, to achieve this, there must be a clear understanding of the requirements of different IoT applications and the suitability of a blockchain platform for a particular application satisfying its underlying requirements. This chapter aims to achieve this goal by describing an evaluation framework which can be utilized to select a suitable blockchain platform for a given IoT application.
       
  • Intersections between IoT and distributed ledger
    • Abstract: Publication date: Available online 14 January 2019Source: Advances in ComputersAuthor(s): Hany F. Atlam, Gary B. Wills The Internet of Things (IoT) is growing exponentially. It allows not only humans but also all various devices and objects in the environment to be connected over the Internet to share their data to create new applications and services which result in a more convenient and connected lifestyle. However, the current centralized IoT architecture faces several issues. For instance, all computing operations of all nodes in the network are carried out using a single server. This creates a single point of failure in which if the server goes down, the entire system will be unavailable. Also, the IoT centralized architecture is an easy target of various types of security and privacy attacks, since all IoT data collected from different devices is under the full authority of a single server. Therefore, adopting one of the Distributed Ledger Technologies (DLTs) for the IoT may be the right decision. One of the popular types of DLTs is the blockchain. It provides an immutable ledger with the capability of maintaining the integrity of transactions by decentralizing the ledger among participating nodes in the blockchain network which eliminates the need for a central authority. Integrating the IoT system with the blockchain technology can provide several benefits which can resolve the issues associated with the IoT centralized architecture. Therefore, this chapter provides a discussion of the intersection between IoT and DLTs. It started by providing an overview of the DLT by highlighting its main components, benefits and challenges. The centralized IoT system is also discussed with highlighting its essential limitations. Then, the integration of blockchain with IoT is presented by highlighting the integration benefits. Various application and challenges of integrating blockchain with IoT are also discussed.
       
  • Blockchain applications in healthcare and the opportunities and the
           advancements due to the new information technology framework
    • Abstract: Publication date: Available online 5 January 2019Source: Advances in ComputersAuthor(s): Ramzi Abujamra, David Randall The promise of blockchain extends into healthcare allowing a transformation of our current system and its use of information technology. The current use of information technology in healthcare can be advanced with blockchain. The fundamental values that blockchain will bring include decentralization due to its distributed ledger technology, interoperability and increased security and immutability. These benefits enable a healthcare system that is integrated, seamless and more secure and with an increased level of compliance. Blockchains offer the opportunity to deliver secure and highly efficient transaction processing between patient, provider and payer and other healthcare parties in a more efficient and seamless way. The use of smart contracts in healthcare is the catalyst by which blockchains can deliver these transactions in a transformative way. The application of blockchains combined with the Internet of Things (IoT) is also a catalyst that will enable these transactions to be processed to disrupt healthcare from its current state at this time. We explore ways that blockchain and its associated information technology will revolutionize our healthcare system that we believe would allow for a more efficient and fluid environment with improved cost efficiencies.
       
  • Experiences With Replicable Experiments and Replication Kits for Software
           Engineering Research
    • Abstract: Publication date: Available online 21 December 2018Source: Advances in ComputersAuthor(s): Steffen Herbold, Fabian Trautsch, Patrick Harms, Verena Herbold, Jens Grabowski Replications and replicable research are currently gaining traction in the software engineering research community. Our research group made an effort in the recent years to make our own research accessible for other researchers, through the provision of replication kits that allow rerunning our experiments. Within this chapter, we present our experiences with replication kits. We first had to learn which contents are required, how to structure them, how to document them, and also how to best share them with other researchers. While this sounds very straightforward, there are many small potential mistakes, which may have a strong negative impact on the usefulness and long-term availability of replication kits. We derive best practices for the content and the sharing of replication kits based on our experiences. Moreover, we outline how platforms for replicable research may further help our community, especially with problems related to the external validity of results. Finally, we discuss the lack of integration of replication kits into most current review processes at conferences and journals. We also give one example for a review process into which replication kits were well-integrated. Altogether, this chapter demonstrates that making research replicable is a challenging task and there is a long road ahead until our community has a generally accepted and enforced standard of replicability.
       
  • Advances in Symbolic Execution
    • Abstract: Publication date: Available online 21 December 2018Source: Advances in ComputersAuthor(s): Guowei Yang, Antonio Filieri, Mateus Borges, Donato Clun, Junye Wen Symbolic execution is a systematic technique for checking programs, which forms a basis for various software testing and verification techniques. It provides a powerful analysis in principle but remains challenging to scale and generalize symbolic execution in practice. This chapter reviews the cutting-edge research accomplishments in addressing these challenges in the last 5 years, including advances in addressing the scalability challenges such as constraint solving and path explosion, as well as advances in applying symbolic execution in testing, security, and probabilistic program analysis.
       
  • Symbolic Execution and Recent Applications to Worst-Case Execution, Load
           Testing, and Security Analysis
    • Abstract: Publication date: Available online 21 December 2018Source: Advances in ComputersAuthor(s): Corina S. Păsăreanu, Rody Kersten, Kasper Luckow, Quoc-Sang Phan Symbolic execution is a systematic program analysis technique which executes programs on symbolic inputs, representing multiple concrete inputs, and represents the program behavior using mathematical constraints over the symbolic inputs. Solving the constraints with off-the-shelf solvers yields inputs that exercise different program paths. Typical applications of the technique include test input generation and error detection. In this chapter we review symbolic execution and associated tools, and describe some of the main challenges in applying symbolic execution in practice: handling of programs with complex inputs, coping with path explosion, and ameliorating the cost of constraint solving. We also survey promising applications of the technique that go beyond checking functional properties of programs. These include finding worst-case execution time in programs, load testing and security analysis, via combinations of symbolic execution with fuzzing.
       
  • Three Open Problems in the Context of E2E Web Testing and a Vision:
           NEONATE
    • Abstract: Publication date: Available online 20 December 2018Source: Advances in ComputersAuthor(s): Filippo Ricca, Maurizio Leotta, Andrea Stocco Web applications are critical assets of our society and thus assuring their quality is of undeniable importance. Despite the advances in software testing, the ever-increasing technological complexity of these applications makes it difficult to prevent errors.In this work, we provide a thorough description of the three open problems hindering web test automation: fragility problem, strong coupling and low cohesion problem, and incompleteness problem. We conjecture that a major breakthrough in test automation is needed, because the problems are closely correlated, and hence need to be attacked together rather than separately. To this aim, we describe Neonate, a novel integrated testing environment specifically designed to empower the web tester.Our utmost purpose is to make the research community aware of the existence of the three problems and their correlation, so that more research effort can be directed in providing solutions and tools to advance the state of the art of web test automation.
       
  • Advances in Using Agile and Lean Processes for Software Development
    • Abstract: Publication date: Available online 16 May 2018Source: Advances in ComputersAuthor(s): Pilar Rodríguez, Mika Mäntylä, Markku Oivo, Lucy Ellen Lwakatare, Pertti Seppänen, Pasi Kuvaja Software development processes have evolved according to market needs. Fast changing conditions that characterize current software markets have favored methods advocating speed and flexibility. Agile and Lean software development are in the forefront of these methods. This chapter presents a unified view of Agile software development, Lean software development, and most recent advances toward rapid releases. First, we introduce the area and explain the reasons why the software development industry begun to move into this direction in the late 1990s. Section 2 characterizes the research trends on Agile software development. This section helps understand the relevance of Agile software development in the research literature. Section 3 provides a walk through the roots of Agile and Lean thinking, as they originally emerged in manufacturing. Section 4 develops into Agile and Lean for software development. Main characteristics and most popular methods and practices of Agile and Lean software development are developed in this section. Section 5 centers on rapid releases, continuous delivery, and continuous deployment, the latest advances in the area to get speed. The concepts of DevOps, as a means to take full (end-to-end) advantage of Agile and Lean, and Lean start-up, as an approach to foster innovation, are the focus of the two following 6 DevOps, 7 The Lean Startup Movement. Finally, Section 8 focuses on two important aspects of Agile and Lean software development: (1) metrics to guide decision making and (2) technical debt as a mechanism to gain business advantage. To wrap up the chapter, we peer into future directions in the area.
       
  • Model-Based Test Cases Reuse and Optimization
    • Abstract: Publication date: Available online 22 February 2018Source: Advances in ComputersAuthor(s): Mohamed Mussa, Ferhat Khendek Several test generation techniques have been proposed in the literature. These techniques target separately specific levels of testing without relating them to each other in order to avoid redundancy and enable reuse and optimization. In this chapter, we look into connecting different levels of testing. We propose a model-based testing framework that enables reusability and optimization across different levels of testing. Test cases at one level are reused to generate test cases of subsequent levels of testing. Furthermore, test cases at one level are optimized by relating them to test cases of preceding testing levels and removed if they are found redundant.
