IoT Botnet Detection Using an Economic Deep Learning Model

The rapid progress in technology innovation usage and distribution has increased in the last decade. The rapid growth of the Internet of Things (IoT) systems worldwide has increased network security challenges created by malicious third parties. Thus, reliable intrusion detection and network forensics systems that consider security concerns and IoT systems limitations are essential to protect such systems. IoT botnet attacks are one of the significant threats to enterprises and individuals. Thus, this paper proposed an economic deep learning-based model for detecting IoT botnet attacks along with different types of attacks. The proposed model achieved higher accuracy than the state-of-the-art detection models using a smaller implementation budget and accelerating the training and detecting processes.Comment: The paper under reviewing proces

Strategy for Developing Expert-System-Based Internet Protocols (TCP/IP)

The Satellite Networks and Architectures Branch of NASA's Lewis Research is addressing the issue of seamless interoperability of satellite networks with terrestrial networks. One of the major issues is improving reliable transmission protocols such as TCP over long latency and error-prone links. Many tuning parameters are available to enhance the performance of TCP including segment size, timers and window sizes. There are also numerous congestion avoidance algorithms such as slow start, selective retransmission and selective acknowledgment that are utilized to improve performance. This paper provides a strategy to characterize the performance of TCP relative to various parameter settings in a variety of network environments (i.e. LAN, WAN, wireless, satellite, and IP over ATM). This information can then be utilized to develop expert-system-based Internet protocols

Telecommunication of stabilizing signals in power systems

Deregulation of the power industry has occurred at a rapid pace, opening some promising competition between suppliers. The result of this competition should be to the benefit of customers.;Telecommunication plays a crucial role in integrating systems and ensuring smooth operation by way of exchanging data and information between various systems that are responsible for monitoring and control of the grid. For example, a Power System Stabilizer (PSS) controller could be placed at one of the generators and requires remote measurements. All the communication schemes within the network generate delays that are characterized in this project using OPNET Modeler. OPNET Modeler is also used to characterize the number of dropped packets.;As a case study, we consider a two-area four-generator (2A4G) and explore the role of communication delay on system stability. Those delays play an important role in the design of a controller that can help the damping of electro-mechanical oscillations between interconnected synchronous generators and therefore maintain the system stability. The network statistics are then imported into Simulink in order to visualize the speed of the shaft w2 as a function of time. Additional communication options to the inter-area oscillation problem are offered at the end of the thesis (use of Virtual Private Network (VPN), use of fiber optic dedicated network, or the use of IPv6 protocol)

Network Traffic Analysis: A Case Study of ABU Network

The Internet is being viewed as a critical component of success by the researchers, teachers and students in the Universities and Colleges. The Objectives of thesis is to identify unproductive network based applications responsible for consuming valuable bandwidth of University network system and to enhance utility of productive applications on a University network. This research work, geared towards analysis on the internet traffic network’s of Ahmadu Bello University (ABU), Zaria as a case study. the monitoring of network traffic was conducted by bandwidth monitoring software, a packet sniffer (using Wireshark Version 165, SVR Rev 40429) configured as a gateway between the University network system and the internet over a 90-day monitoring period in a schedule of 15 minutes daily, 30 minutes weekly and 2 hours monthly. The data (packets) captures was further analysed using MATLAB which is a tool for graphing network data from which conclusions from the graphs was drawn that ABU’s current network traffic is underutilized and far from optimal in terms of Internet Inbound/Outbound traffic generated by its users (staff/students). It has also been observed that defensive bandwidth management is insufficient in respect to the institution’s aims and objectives on its network usage. This emphasises the need for improved bandwidth management and optimization. Keyword: Network monitoring traffic, Monitoring software (packet sniffer), Packet capture and Traffic analysis.

Honeypot for wireless IoT networks

Ciele tejto práce ležia v teoretickej analýze konceptu Internet vecí (IoT) a jeho bezpečnostných problémov, praktickom výskume a vývoji nového unikát-neho zariadenia zvaného "IoT honeypot". Analytická časť práce sumarizuje existujúce hardvérové a softvérové riešenia, a sústredí sa na technológiu Soft-vérom definovaného rádia (SDR), ktorá bola použitá na vývoj IoT honeypot-u. Vyvíjaný prototyp v súčasnosti podporuje rozšírený Z-Wave protokol. Avšak, dizajn je dosť univerzálny na to, aby v budúcnosti podporoval ďalšie IoT protokoly. Motiváciou tejto práce bolo vytvoriť zariadenie, ktoré dokáže zbierať informácie o IoT komunikácii, detegovať potenciálnych útočníkov, a pôsobiť ako návnada, ktorá komplikuje útočníkom objaviť a prebrať kon-trolu nad skutočnými nasadenými IoT zariadeniami, ako sú senzory, spínače, a podobne. Výstupom tejto práce je funkčný IoT honeypot, ktorý podporuje viacero režimov fungovania (napríklad pasívny alebo interaktívny režim), a môže byť nasadený ako súčasť Z-Wave infraštruktúry. Predstavuje komple-ment k ostatným bezpečnostným nástrojom a mechanizmom, ktoré zvyšujú úroveň bezpečnosti IoT infraštruktúry.The goals of this thesis lay among theoretical analysis of the Internet of Things (IoT) concept and its security issues, and practical research and development of a new unique device called "IoT honeypot." The analytical part of the thesis summarizes existing hardware and software solutions and concentrates on Software Defined Radio (SDR) technology, which was used for the development of IoT honeypot. The developed prototype currently supports a wide-spread Z-Wave protocol. However, the design is universal enough to support other IoT protocols in the future. The motivation of this thesis was to create a device that can collect information about IoT traffic, detect potential attackers, and act as a decoy that complicates attackers to discover and hack real deployed IoT devices, such as sensors, switches, and so on. The result of the thesis is a working IoT honeypot that supports multiple modes of operation (such as passive or interactive mode), and that can be deployed as a part of a Z-Wave infrastructure. It is as a complement to other security tools and mechanisms that increase the security of IoT infrastructure

Implementación de un sistema SDN para la movilidad en redes OMNIRAN

This document details all the information needed to understand and test distributed mobility management using the SDN paradigm. This project stars by an analysis of the mobility problem in dense networks. Traditionally mobility has been managed with hierarchical approaches extending the current mobility protocols. But thinking in the future evolution of the network into dense environments some scalability problems appear. The traditional centralized elements may not be able to handle all the traffic in the network and bottlenecks appear at the Mobility Anchors. Nowadays, the problems related to scalability are mostly resolved with hardware upgrades, but in dense environments this couldn’t be enough and surely it would be quite expensive. To find a solution to this problem the IETF has chartered the Distributed Mobility Management (DMM) Group.This project focus on implementing a DMM-based mobility solution designed within the EU FP7 CROWD project. Once the analysis of the problem ended and the requirements of the theoretical solution were defined, we developed all the necessary elements to physically build a distributed network using SDN to manage layer 2 and layer 3.The entities of the network are defined by the CROWD projectin its related publications[9][10]. These districts were run using an SDN implementation called OpenFlow. With all the elements developed we proceed to perform the necessary tests in order to evaluate the distributed mobility management as a solution. This document explains the full design, execution and validationprocesses. Finally all the measurements and statistical data are detailed in order to have an approximation of the services that could achieve the developed network.Ingeniería Telemátic

Performance Evaluation of MPEG-4 Video Transmission over IP-Networks: Best-Effort and Quality-of-Service

The demand for video communication over internet has been growing rapidly in recent years and the quality of video has become a challenging issue for video transmission. Different types of video coding standards like MPEG-2 and MPEG-4 have been developed to support application like video transmission. MPEG-2 which requires high bit rate transmission has been successful video standard for DVD and satellite digital broadcasting. On the other hand, MPEG-4 supports low bit rate and is suitable for transmitting video over IP networks. In this paper, MPEG-4 Video standard has been used for evaluating the performance of video transmission over two IP networks:- Best-effort and Quality of Service (QoS). For both of the best-effort and QoS IP networks, peak signal noise ratio (PSNR), throughput, frame and packet statistics have been considered as performance metrics. The calculated values of these performance metrics reflect that video transmission over QoS IP network is better than that of the best-effort network.
