    The issues of cybersecurity these days are extremely relevant. With the massive use of the Cloud Computing system, new concerns about the processes to provide this technology with security appeared. The Cloud Computing infrastructure is based on virtualization and distributed computing, often using the shared resource pooling system. For these scenarios, key issues are considered: authentication, and access control. These issues make relevant the following items: data security, regulatory data, privileged access and data recovery. The issue of security in cloud computing involves encryption, it is important to specify the advantages and disadvantages of symmetric encryption and asymmetric encryption. Parallel to this it is important to develop a set of policies for the creation of passwords and subsequent maintenance and alteration of them, as well as their security. the two mandatory pillars for security in Cloud Computing are encryption and a strong passwords policy

    Extending the military principle of maneuver into war-fighting domain of cyberspace, academic and military researchers have produced many theoretical and strategic works, though few have focused on researching actual applications and systems that apply this principle. We present our research in designing, building and modeling maneuverable applications in order to gain the system advantages of resource provisioning, application optimization, and cybersecurity improvement. We have coined the phrase “Maneuverable Applications” to be defined as distributed and parallel application that take advantage of the modification, relocation, addition or removal of computing resources, giving the perception of movement. Our work with maneuverable applications has been within shared computing resources, such as the Clemson University Palmetto cluster, where multiple users share access and time to a collection of inter-networked computers and servers. In this dissertation, we describe our implementation and analytic modeling of environments and systems to maneuver computational nodes, network capabilities, and security enhancements for overcoming challenges to a cyberspace platform. Specifically we describe our work to create a system to provision a big data computational resource within academic environments. We also present a computing testbed built to allow researchers to study network optimizations of data centers. We discuss our Petri Net model of an adaptable system, which increases its cybersecurity posture in the face of varying levels of threat from malicious actors. Lastly, we present work and investigation into integrating these technologies into a prototype resource manager for maneuverable applications and validating our model using this implementation

    As the term \u27information technology\u27 has many meanings for various stakeholders and continues to evolve, this work presents a comprehensive approach for developing curriculum guidelines for rigorous, high quality, bachelor\u27s degree programs in information technology (IT) to prepare successful graduates for a future global technological society. The aim is to address three research questions in the context of IT concerning (1) the educational frameworks relevant for academics and students of IT, (2) the pathways into IT programs, and (3) graduates\u27 preparation for meeting future technologies. The analysis of current trends comes from survey data of IT faculty members and professional IT industry leaders. With these analyses, the IT Model Curricula of CC2005, IT2008, IT2017, extensive literature review, and the multinational insights of the authors into the status of IT, this paper presents a comprehensive overview and discussion of future directions of global IT education toward 2025

    Extending the military principle of maneuver into the war-fighting domain of cyberspace, academic and military researchers have produced many theoretical and strategic works, though few have focused on researching the applications and systems that apply this principle. We present a survey of our research in developing new architectures for the enhancement of parallel and distributed applica-tions. Specifically, we discuss our work in applying the military concept of maneuver in the cyberspace domain by creating a set of applications and systems called “ma-neuverable applications.” Our research investigates resource provisioning, application optimization, and cybersecurity enhancement through the modification, relocation, addition or removal of computing resources. We first describe our work to create a system to provision a big data computational re-source within academic environments. Secondly, we present a computing testbed built to allow researchers to study network optimizations of data centers. Thirdly, we discuss our Petri Net model of an adaptable system, which increases its cyber security posture in the face of varying levels of threat from malicious actors. Finally, we present evidence that traditional ideas about extending maneuver into cyberspace focus on security only, but computing can benefit from maneuver in multiple manners beyond security

    The Spectre and Meltdown flaws in modern microprocessors represent a new class of attacks that have been difficult to mitigate. The mitigations that have been proposed have known performance impacts. The reported magnitude of these impacts varies depending on the industry sector and expected workload characteristics. In this paper, we measure the performance impact on several workloads relevant to HPC systems. We show that the impact can be significant on both synthetic and realistic workloads. We also show that the performance penalties are difficult to avoid even in dedicated systems where security is a lesser concern

    Artificial intelligence in the cyber domain: Offense and defense

    Get PDF
    Artificial intelligence techniques have grown rapidly in recent years, and their applications in practice can be seen in many fields, ranging from facial recognition to image analysis. In the cybersecurity domain, AI-based techniques can provide better cyber defense tools and help adversaries improve methods of attack. However, malicious actors are aware of the new prospects too and will probably attempt to use them for nefarious purposes. This survey paper aims at providing an overview of how artificial intelligence can be used in the context of cybersecurity in both offense and defense.Web of Science123art. no. 41
