Wireless local area network management frame denial- of-service attack detection and mitigation schemes

Wireless Local Area Networks (WLAN) are increasingly deployed and in widespread use worldwide due to its convenience and low cost. However, due to the broadcasting and the shared nature of the wireless medium, WLANs are vulnerable to a myriad of attacks. Although there have been concerted efforts to improve the security of wireless networks over the past years, some attacks remain inevitable. Attackers are capable of sending fake de-authentication or disassociation frames to terminate the session of active users; thereby leading to denial of service, stolen passwords, or leakage of sensitive information amongst many other cybercrimes. The detection of such attacks is crucial in today's critical applications. Many security mechanisms have been proposed to effectively detect these issues, however, they have been found to suffer limitations which have resulted in several potential areas of research. This thesis aims to address the detection of resource exhaustion and masquerading DoS attacks problems, and to construct several schemes that are capable of distinguishing between benign and fake management frames through the identification of normal behavior of the wireless stations before sending any authentication and de-authentication frames. Thus, this thesis proposed three schemes for the detection of resource exhaustion and masquerading DoS attacks. The first scheme was a resource exhaustion DoS attacks detection scheme, while the second was a de- authentication and disassociation detection scheme. The third scheme was to improve the detection rate of the de-authentication and disassociation detection scheme using feature derived from an unsupervised method for an increased detection rate. The effectiveness of the performance of the proposed schemes was measured in terms of detection accuracy under sophisticated attack scenarios. Similarly, the efficiency of the proposed schemes was measured in terms of preserving the resources of the access point such as memory consumptions and processing time. The validation and analysis were done through experimentation, and the results showed that the schemes have the ability to protect wireless infrastructure networks against denial of service attacks

Network performance monitors

Over the last 10 years both industry and academia have conducted extensive research and development in the areas of local area network management and performance. This thesis investigates some different ways of measuring the performance of local area networks and studies hardware and software systems designed to watch over network performance and events. These systems are termed network performance monitors. As part of the thesis, a network performance monitor has been implemented to monitor TOOLSNET, an Ethernet based local area network, supervised by the Engineering Tools Technology group at Compugraphic Corporation. This network performance monitor is called TOOLSNET ANALYSIS PACKAGE, or TAP for short. TAP runs Monday through Friday, from 8 a.m. to 5 p.m. to monitor TOOLSNET performance during working hours. A summary of the measurements from one of these 5 day sessions is reported in this paper. This summary includes the following tables: one showing a system by system contribution to TOOLSNET traffic for the session; another that shows the amount the network was utilized each day of the session; another that shows the total number of random errors experienced by TOOLSNET during the session; another that shows asymptotic throughput utilization, perceived utilization, relative load, and average response time for each day of the session; another that shows source-to-destination traffic for each day of the session

Design and Logistics for a LAN Management Course

This paper outlines an implementation for a hands-on Local Area Network (LAN) management course in the undergraduate curriculum of a department of Information Systems. Three major problems are addressed: faculty preparation, resource allocation, and course design/logistics. There are special difficulties in designing such a course because of the hardware preparation involved and the assignment of supervisor rights to a large number of students simultaneously for a single file server. A course outline and a sample practical exercise are given. This course has been successfully implemented and received a favorable student response

Web-Based Network Device Monitoring Tool Using Simple Network Management Protocol (Snmp)

The Internet enables different computer networks to join together into one network in which many different models of network devices can co-exist with each other. Standard management protocol is necessary for the purpose of managing these networks. SNMP (Simple Network Management Protocol), one of the standard protocols, is designed for this open-class management function and is successfully implemented. This thesis suggests a monitoring of network device statistical data from a remote place. This approach reduced the complexity of existing techniques, which are basically operable in specific operating system and having no standard Graphical User Interface (GUI). To address this problem, a system based on WWW standard tool is developed which is SNMP compatible as well as operable with any network device. The network device monitoring tool is a client program, which is managed and could be contacted with the server program. A web server and a browser are to provide static, dynamic, and interactive management information. A web server, which plays a managing role, offers a variety of types of information. An SNMP agent, which cooperates with a web server, uses SNMP protocol and provides access to management information of network devices/agents. The implementation of the user interface using the web-based technique of Java Applet makes it possible for a manager to easily search and manage agent Management Information Base (Mill) through a browser. Java SNMP class files and SNMP Applet Server (SAS) classes are used inside the Web-server to communicate with network devices. The network device monitoring tool is configured to collect network statistical data. It can monitor the real time graph on the basis of MIB variable from remote place and shows more efficient than the existing tool

The association of external auditor's attributes with management fraud risk assessment in financial reporting: empirical evidence from Yemen

As stated by the International Standard of Auditing (ISA No. 240), the effectiveness of the external auditors' attributes is the primary process in management fraud risk assessment (MFRA). Therefore, the aim of this study is to examine the associations of external auditor effectiveness-related attributes and independent-related factors with MFRA in the context of Yemen. To achieve the objective of this study, questionnaires were distributed out to 410 external auditors working in private audit firms and the Yemeni Central Organization for Control and Accounting (COCA) for the year 2012. A total of 273 questionnaires were returned back out of which 19 were unusable. As such, the final sample of this study consists of 254 external auditors. Multiple regression analysis was used to test the study's hypotheses. This study finds positive associations of the external auditor's effectiveness score and external auditor's independence score with MFRA. Furthermore, questioning discussion ability, professional qualification, fraud detection experience, information technology (IT) skill, training on fraud detection, and social relationships are reported to have positive and significant associations with MFRA, while job position is found to have a negative association. The findings of this study indicate that Yemeni government and COCA should issue new regulations to increase the external auditors' awareness and effectiveness towards MFRA. This study also indicates that the audit profession in Yemen needs more control, regulations, laws and policies to enhance the structure of the external auditors' decision in issues related to MFRA in order to protect the interests of demand-supply sides of audit services and the related parties. Moreover, this study has implications for the Yemeni policy makers and government to enrich the external auditors' effectiveness and independence by issuing new regulations, new laws, and applying more control on the quality of auditing profession to protect the economy and the society stability

On the management and performance of a class of local area networks

This dissertation is concerned with the management and performance issues of those register-insertion (R-I) ring type local area networks (LANs) which employ the message removal by destination node protocol. A typical example of such a network is the Distributed Loop Computer Network (DLCN). developed by Liu et al for fundamental research in the field of distributed computing. After considering the management issues of low cost R-J LANs. the research deals with performance analysis of the dynamically reconfigurable register-insertion (DRR) network. In the first part of this research. a set of management functions is identified which are desirable and can be provided economically by a low cost LAN. A unique feature of the DLCN is that messages are removed from the network by the destination node. that is. messages do not travel whole of the loop. Therefore. it is not possible for a special control node to monitor the data traffic on the network without providing support functionality in each network access unit (NAU). The minimum functionality which must be provided in each NAU is identified in the thesis. A skeleton network was implemented to verify the feasibility of the proposed scheme. A paper describing the findings of this research was published and is reproduced as appendix A. In the second part of this research. a new feature of the DLCN network is introduced. namely. that the performance of a network employing removal by destination protocol can be improved by reconfiguring the network in a particular way. A methodology to find the optimal configuration is developed and is shown. by worked examples. to lead to improved performance. The findings of this research are particularly applicable to the dynamically reconfigurable register-insertion (DRR) network. A paper dealing with the optimisation of a hypothetical fully connected DRR network has been accepted for publication. Another paper. which considers the general case of less than fully connected DRR networks. is to be published. Both papers are reproduced as append ices Band C. Finally. a performance study of the ORR network is undertaken. As there seems to be no published attempt at formal analysis or simulation of a ORR network. a survey of literature dealing with performance study of the basic OLeN is performed. A simulation model of the DRR was then developed and implemented to verify the results arrived at in the previous section. Later. a queueing model of the DRR network. based on the work of Bux and Schlatter [7] is developed and analysed. Both simulation and analysis support the claim that the performance of a DRR network can be improved by adopting the configuration strategy developed in this thesis
