Detecting flooding based DoS attack in cloud computing environment using covariance matrix approach

The internet is gaining a lot of importance day by day, especially with the emergence of cloud technology. This new technology has made a new computing service to end users that include, PaaS, SaaS. On the other hand, this technology was accompanied with some shortages. The most serious obstacle is the security challenges because of the cloud is characterized by computing resource sharing and multi-tenancy features and as a result flooding based denial of service attack has been observed. This effect on performance and quality of service on cloud. To overcome this security challenge, there are several methods to detect and prevent this kind of attack. Most of these approaches are using statistical and/or artificial intelligence methods. In this research paper a new model to detect flooding based DoS attack in cloud environment has been suggested consisting three phases. (1) The first-phase is to model the normal traffic pattern for baseline profiling and (2) the second phase is the intrusion detection processes and (3) finally prevention phase. The covariance Matrix mathematical model is used as detecting method. The phase (1) and (2) have been implemented in real test bed. From the result, it is proven that we can detect the flooding attack effectively.

Comparing the Accuracy of End-to-End Network Performance Measurement Testbed and Simulation Model for Data Transfers in Heterogeneous Environment

We present a novel approach for the measurement of one-way delays and throughput between network nodes in heterogeneous environment. This research investigates performance evaluation of remote data transfers on heterogeneous services and technologies environment. We propose an enhanced equation to evaluate the performance of network traffic management via Little Law and Queuing theory to improve the evaluation algorithm. To get accuracy results on the performance of simulation model, we measure (verify and validate) data from lab experiment. We use network management tool to capture those data and Ping Plotter application (network analyzer) to generate traffic. As a result, this simulation model can provide a good approximation of the real traffic (one-way delays and throughput) observed in the real network environment.

Implementing of IPv6 Protocol Environment at University of Kuala Lumpur: Measurement of IPv6 and IPv4 Performance

IPv6 provides a platform for new Internet functionality. It includes support for real-time flows, provider selection, and host mobility, end-to-end security, auto-configuration, and auto-reconfiguration. It solves the Internet scaling problem, provides a flexible transition mechanism for the current Internet, and was designed to meet the needs of new markets such as nomadic personal computing devices, networked entertainment, and device control. The significant of this study is to describe on development of a video conferencing system with multimedia capabilities (Video + Audio) over IPv6 environment at University of Kuala Lumpur (campus environment). The beneficial and apparent of this research is to introduce a new service of the Internet Protocol (IPv6) at the campus environment. The concept of multicasting is be explored as this was used in the development of the video conferencing (Video + Audio). By comparing IPv6 and IPv4 video conferencing performance, we focus on problems that are only present in the IPv6 environments.

A prototype Of Web Based Temperature Monitoring system

this research was developed to produce a prototype product of a Web Based Temperature Monitoring system that allows the user to continuously monitor the temperature condition of a room. This prototype system is enhancement from the existing system that allowed the data to be monitored anytime and anywhere from the Internet and using new approach. This research development project was divided into two parts that involved with the hardware and software. The hardware part involved building the temperature sensor board and for the software part involved written programming and construct coding using C language program. The programs then are uploaded into the microcontroller which then created Visual Basic 6.0 application to display the temperature and saves the data into a database. An active Server Page (ASP) scripting language is used as server side scripting to publish the current temperature at the web browser. This prototype of a Web-Based Temperature Monitoring has met all the objectives derived and planned. The research project is considered successful and ready to be launched in the real system implementations.

Implementation of Video Voice over IP in Local Area Network Campus Environment

In this research, we propose an architectural solution to integrate the video voice over IP (V2oIP) services in campus environment network. Voice over IP (VoIP) technology has become a discussion issue for this time being. Today, the deployment of this technology on an organization truly can give a great financial benefit over traditional telephony. Therefore, this study is to analyze the V2oIP and investigate the performance areas evolved with the Quality of Service (QoS) delivered by video phone system. This study focuses on quality of voice and video, packet loss, delay time and jitter through the USB Video Phone and soft phone. In this study, network management system (NMS) is used to monitor and capture the performance of V2oIP in campus environment. In addition, the most apparent of implementing soft phone and USB phone in campus environment is to define the best situation (peak and non peak hours) that can be used in operational environment. Based on the finding result, it shows that users may experience V2oIP quality service degradations due to delays and losses in the LAN during peak hours.
