UAV Based 5G Network: A Practical Survey Study
Unmanned aerial vehicles (UAVs) are anticipated to significantly contribute
to the development of new wireless networks that could handle high-speed
transmissions and enable wireless broadcasts. When compared to communications
that rely on permanent infrastructure, UAVs offer a number of advantages,
including flexible deployment, dependable line-of-sight (LoS) connection links,
and more design degrees of freedom because of controlled mobility. Unmanned
aerial vehicles (UAVs) combined with 5G networks and Internet of Things (IoT)
components have the potential to completely transform a variety of industries.
UAVs may transfer massive volumes of data in real-time by utilizing the low
latency and high-speed abilities of 5G networks, opening up a variety of
applications like remote sensing, precision farming, and disaster response.
This study of UAV communication with regard to 5G/B5G WLANs is presented in
this research. The three UAV-assisted MEC network scenarios also include the
specifics for the allocation of resources and optimization. We also concentrate
on the case where a UAV does task computation in addition to serving as a MEC
server to examine wind farm turbines. This paper covers the key implementation
difficulties of UAV-assisted MEC, such as optimum UAV deployment, wind models,
and coupled trajectory-computation performance optimization, in order to
promote widespread implementations of UAV-assisted MEC in practice. The primary
problem for 5G and beyond 5G (B5G) is delivering broadband access to various
device kinds. Prior to discussing associated research issues faced by the
developing integrated network design, we first provide a brief overview of the
background information as well as the networks that integrate space, aviation,
and land
5G Network Management, Orchestration, and Architecture: A Practical Study of the MonB5G project
The cellular device explosion in the past few decades has created many
different opportunities for development for future generations. The 5G network
offers a greater speed in the transmissions, a lower latency, and therefore
greater capacity for remote execution. The benefits of AI for 5G network
slicing orchestration and management will be discussed in this survey paper. We
will study these topics in light of the EU-funded MonB5G project that works
towards providing zero-touch management and orchestration in the support of
network slicing at massive scales for 5G LTE and beyond
A Vertical and Horizontal Intelligent Dataset Reduction Approach for Cyber-Physical Power Aware Intrusion Detection Systems
The Cypher Physical Power Systems (CPPS) became vital targets for intruders because of the large volume of high speed heterogeneous data provided from the Wide Area Measurement Systems (WAMS). The Nonnested Generalized Exemplars (NNGE) algorithm is one of the most accurate classification techniques that can work with such data of CPPS. However, NNGE algorithm tends to produce rules that test a large number of input features. This poses some problems for the large volume data and hinders the scalability of any detection system. In this paper, we introduce VHDRA, a Vertical and Horizontal Data Reduction Approach, to improve the classification accuracy and speed of the NNGE algorithm and reduce the computational resource consumption. VHDRA provides the following functionalities: (1) it vertically reduces the dataset features by selecting the most significant features and by reducing the NNGE's hyperrectangles. (2) It horizontally reduces the size of data while preserving original key events and patterns within the datasets using an approach called STEM, State Tracking and Extraction Method. The experiments show that the overall performance of VHDRA using both the vertical and the horizontal reduction reduces the NNGE hyperrectangles by 29.06%, 37.34%, and 26.76% and improves the accuracy of the NNGE by 8.57%, 4.19%, and 3.78% using the Multi-, Binary, and Triple class datasets, respectively.This work was made possible by NPRP Grant # NPRP9-005-1-002 from the Qatar National Research Fund (a member of Qatar Foundation).Scopu

Adversarial-Aware Deep Learning System based on a Secondary Classical Machine Learning Verification Approach
Deep learning models have been used in creating various effective image
classification applications. However, they are vulnerable to adversarial
attacks that seek to misguide the models into predicting incorrect classes. Our
study of major adversarial attack models shows that they all specifically
target and exploit the neural networking structures in their designs. This
understanding makes us develop a hypothesis that most classical machine
learning models, such as Random Forest (RF), are immune to adversarial attack
models because they do not rely on neural network design at all. Our
experimental study of classical machine learning models against popular
adversarial attacks supports this hypothesis. Based on this hypothesis, we
propose a new adversarial-aware deep learning system by using a classical
machine learning model as the secondary verification system to complement the
primary deep learning model in image classification. Although the secondary
classical machine learning model has less accurate output, it is only used for
verification purposes, which does not impact the output accuracy of the primary
deep learning model, and at the same time, can effectively detect an
adversarial attack when a clear mismatch occurs. Our experiments based on
CIFAR-100 dataset show that our proposed approach outperforms current
state-of-the-art adversarial defense systems.Comment: 17 pages, 3 figure
Intrusion detection and prevention of web service attacks for software as a service:Fuzzy association rules vs fuzzy associative patterns
Cloud computing inherits all the systems, networks as well asWeb Services’ security vulnerabilities, in particular
for software as a service (SaaS), where business applications or services are provided over the Cloud as Web Service (WS). Hence, WS-based applications must be protected against loss of integrity, confidentiality and availability when they are deployed over to the Cloud environment. Many existing IDP systems address only attacks mostly occurring at PaaS and IaaS. In this paper, we present our fuzzy association rule-based (FAR) and fuzzy associative pattern-based (FAP) intrusion detection and prevention (IDP) systems in defending against WS attacks at the SaaS level. Our experimental results have validated the capabilities of these two IDP systems in terms of detection of known attacks and prediction of newvariant attacks
with accuracy close to 100%. For each transaction transacted over the Cloud platform, detection, prevention or prediction is carried out in less than five seconds. For load and volume testing on the SaaS where the system is under stress (at a work load of 5000 concurrent users submitting normal, suspicious and malicious transactions over a time interval of 300 seconds), the FAR IDP system provides close to 95% service availability to normal transactions. Future work involves determining more
quality attributes besides service availability, such as latency, throughput and accountability for a more trustworthy SaaS

Multi-Layer Attack Graph Analysis in the 5G Edge Network Using a Dynamic Hexagonal Fuzzy Method
Overall, 5G networks are expected to become the backbone of many critical IT applications. With 5G, new tech advancements and innovation are expected; 5G currently operates on software-defined networking. This enables 5G to implement network slicing to meet the unique requirements of every application. As a result, 5G is more flexible and scalable than 4G LTE and previous generations. To avoid the growing risks of hacking, 5G cybersecurity needs some significant improvements. Some security concerns involve the network itself, while others focus on the devices connected to 5G. Both aspects present a risk to consumers, governments, and businesses alike. There is currently no real-time vulnerability assessment framework that specifically addresses 5G Edge networks, with regard to their real-time scalability and dynamic nature. This paper studies the vulnerability assessment in the 5G networks and develops an optimized dynamic method that integrates the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) with the hexagonal fuzzy numbers to accurately analyze the vulnerabilities in 5G networks. The proposed method considers both the vulnerability and 5G network dynamic factors such as latency and accessibility to find the potential attack graph paths where the attack might propagate in the network and quantifies the attack cost and security level of the network. We test and validate the proposed method using our 5G testbed and we compare the optimized method to the classical TOPSIS and the known vulnerability scanner tool, Nessus
