    A Holistic–Based Digital Forensic Readiness Framework For Zenith Bank, Nigeria
    (International Conference on Computational and Social Sciences, 2015-08-25) Abdullahi, Adamu Garba; Maheyzah Md Siraj
    The advancement of internet has made many business organizations conduct their operation automatically, in effect its open a possibly dangerous unforeseen information security incidents of both illegal and civil nature. Therefore, if any organization does’t arrange themselves for such instances, it’s likely that vital significant digital evidence will be damage. In other word an organization should has a digital forensic readiness framework (DFR). DFR is the capacity of anyassociation to exploit its prospective to use digital evidence whilst minimizing the cost of investigation. Subsequently, in order to prepare organizations for incident responds, the application of digital forensic readiness policies and procedures is important. Contemporary lack of forensic skills is one of the factors that make organizations reluctant to implement digital forensics. This project propose a holistic-based framework of DFR and investigate how it can be applied to Zenith Bank Plc. This paper surveys existing frameworks to identify the best-suited practical components for Zenith Bank’s operational unit

    A Recommended Digital Forensic Readiness Framework For Nigerian Banks
    (International Journal of Development Research, 2019-08-28) Abdullahi, Adamu Garba; Aliyu Musa Bade
    With the coming of the internet manual method of doing businesses has change dramatically to a computerized way of doing operations, similarly it also possess a threat to information security. Consequently, organizations’ that fells to address or take serious security measures are likely to fall under cyber-attacks, therefore vital information will be damage. To minimize such occurrences in both public and private organization there is a need to have digital forensic framework that they will be used in other to protect sensitive information from being compromise. Digital forensic framework (DFR) helps to exploit the use of evidence and also reducing the cost of investigation. Moreover, to prepare an organization for incident respond DFR policies and procedures are important to be implemented. Therefor this paper has proposed a framework that will be used to minimize attacks to sensitive information by cyber attackers, the framework was designed by surveying the existing frameworks available so as to find the suitable components to be used in Nigerian banking sectors and a qualitative approach was used to seek expert view on the proposed framework, the results shows the components are likely to be used in most financial sector in Nigeria as it covers the major components needed for investigations.

    A Review On Security Issues In Wireless Sensor Networks
    (International Journal of Recent Academic Research, 2019-08-21) Aliyu Musa Bade; Abdullahi, Adamu Garba
    With increasing dependency on technology, Wireless Sensor Networks (WSNs) had gained more and more popularity in the areas of communication, sensing and computing among investors as well as researchers over the years. The proceeds had since been able to simplify complexity in sensing networks, revealing previously unnoticed observable facts. Major research activities being carried out in this field includes deployment, localization, synchronization, architecture, middleware, security, designing less power consuming devices, abstractions and higher level algorithms for sensor specific issues. However, WSN designs still exhibits security issues in their applications that are of concern. This paper explains a synopsis of ongoing research activities, various security problems involved in wireless sensor networks and possible solutions. The paper also reviewed into the various types of successful attacks carried out on these devices to provide future researchers with clues on how to improve their designs

    Review on Digital Forensic Framework and Its Applicability in Organization
    (International Journal of Academic in Engineering Trends & Multidisciplinary, 2019-02-02) Abdullahi, Adamu Garba; Ibrahim Bukar Dauda; Ya’u Nuhu
    The advance of the internet has made many business organizations conduct their operation automatically, this new way of doing business has also opened potentially harmful unforeseen information security incidents of both illegal and civil nature, with the potential to cause harm to the organization's business. Therefore, if an organization does not prepare itself for such incidents, it‟s likely that important relevant digital evidence will be damage. An organization not being able to respond effectively to an incident could affect the business. Forensic readiness is the capacity of an organization to exploit its prospective to use digital evidence whilst minimizing the cost of investigation subsequently, to prepare organizations for incident responses, the implementation of digital forensic readiness policies and procedures is important. In this research paper, the aims are to determine the concept of Digital forensic readiness (DRF) and how its strength and limitation would guide the organization to adopt the suitable framework for their organization. The review of the recent framework was achieved and its applicability was explained as well.

    An Empirical Study of IPV6 Multicast Routing over a Virtual Local Area Network
    (International Journal of Applied Information Systems (IJAIS), 2016-08-06) A. A. Obiniyi; Ahiaba Solomon
    The Internet Protocol Version 6 was designed to efficiently improve on the existing functionalities of Internet Protocol Version 4 and to introduce new constructs that it lacks. Though IPv6 is not an extension of IPv4, as the two protocols have different specifications. Both the new and the formal protocol use multicast routing for many of their operations; this implies multicast routing is core in the protocols. This experiment became imperative especially in this era everyone is looking forward to using IPv6 as the default network. This paper tested the performance of IPv6 multicast routing over a virtual local area network. Graphical Network Simulator 3 was used to configure the network and Microsoft Hyper-V was used as the hypervisor on which the six virtual machines (hosts) reside. Parameters such as throughput, latency variations, data loss and the network over heads were examined. The experiment has shown that, IPv6 multicast routing over a virtual network has 100% throughput, the jitter (variations in latency) varies among the hosts in all the running scenarios, but low and stabled jitters were noticed as the running duration increases and the number of streaming increase from one multicast stream to running two multicast streams simultaneously. There was no data loss.

    A Performance Study of IPV6 Multicast Routing over a Dual Stack Virtual Local Area Network
    (International Journal of Computer Applications, 2016-08-16) ThankGod Sani; A. A. Obiniyi; Ahiaba Solomon
    The shortage address space of the Internet Protocol Version 4 (IPv4) was the major factor that gave birth to the development of Internet Protocol Version 6 (IPv6). Initially, when the shortage alarmed, network experts used mechanisms like Classless Inter Domain Routing and Address Translation to remedies and slow down the exhaustion rate, yet the necessity for IPv6 could not be avoided. Finally, IPv6 emerged in 1998. Another issue however emerged as well, the migration to the new protocol. Since the arrival date up till now IPv6 is not the default Internet routing protocol. As result of the slow migration process, IPv6 has been running alongside with IPv4 on infrastructures partly meant for IPv4 in a dual stack network. The later and the former protocols employed multicast routing as integral of part their operations; this implies multicast routing is an integral part of the two protocols. This paper tests the performance IPv6 multicast routing over a dual stack virtual local area network. Graphical Network Simulator 3 was used to configure the network and Microsoft Hyper-V was used as the hypervisor on which the six virtual machines (hosts) reside. Parameters such as throughput, latency variations, data lost and the network over heads were measured. The experiment has shown that IPv6 multicast routing did not performed well running it alongside with IPv4, therefore, after more examination, running IPv6 multicast routing alongside IPv4 multicast in dual Stack network should be discontinued.

    Comprehensive Evaluation Of Appearance-Based Techniques For Palmprint Features Extraction Using Probabilistic Neural Network, Cosine Measures And Euclidean Distance Classifiers
    (UNIVERSITY OF PITESTI SCIENTIFIC BULLETIN, 2018-08-08) Akande Oluwatobi Noah; Abikoye O. C; Adeyemo I. A; Ogundokun R. O; Aro T. O
    Most biometric systems work by comparing features extracted from a query biometric trait with those extracted from a stored biometric trait. Therefore, to a great extent, the accuracy of any biometric system is dependent on the effectiveness of its features extraction stage. With an intention to establish a suitable appearance based features extraction technique, an independent comparative study of Independent Component Analysis (ICA), Linear Discriminant Analysis (LDA) and Principal Component Analysis (PCA) algorithms for palmprint features extraction is reported in this article. Euclidean distance, Probabilistic Neural Network (PNN) and cosine measures were used as classifiers. Results obtained revealed that cosine metrics is preferable for ICA features extraction while PNN is preferable for LDA features extraction. Both PNN and Euclidean distance yielded a better recognition rate for PCA. However, ICA yielded the best recognition rate in terms of FAR and FRR followed by LDA then PCA

    (Springer Nature Switzerland, 2019-08-08) Akande Oluwatobi Noah; Abikoye Christiana Oluwakemi; Adebiyi Marion Olubunm; Kayode Anthonia Aderonke; Adegun Adekanmi Adeyinka; Ogundokun Roseline Oluwaseun
    Security and privacy of patients’ information remains a major issue of concern among health practitioners. Therefore, measures must be put in place to ensure that unauthorized individual do not have access to this information. However, the adoption of digital alternative of retrieving and documenting medical information has further opened it up to more attacks. This article presents a modified blowfish algorithm for securing textual and graphical medical information. The F-function used in generating round sub-keys was strengthened so as to produce a strong key that could resist differential attacks. Number of Pixel Change Rate (NPCR) and Unified Average Changing Intensity (UACI) of 98.85% and 33.65% revealed that the modified algorithm is sensitive to changes in its key and also resistive to differential attacks. Furthermore, the modified algorithm demonstrated a better encryption and decryption time than the existing blowfish algorithm.
