Wireless Standards

Wired networks add to cost and space required to setup while wireless networks are easy to expand without adding complexity of cables. Most organizations implement wireless networks as an extension to an existing wired connection by installing multiple access points at various locations to cover larger area. The wi-fi network users can be assigned limited and restricted access to the actual wired network and organizational resources. Although less reliable, wireless networks offer mobility, flexibility, ease of deployment, scalability with reduced cost of implementation. However, besides these many advantages, wireless network expands the security threat level by offering ease of intercepting network traffic to the hackers via open networks. Hence, there is a need to determine the potential wi-fi security threats, attacks, attacking tools, and possible countermeasures to be used to secure organizational wireless networks. This chapter focuses on different IEEE 802.11 wireless standards, authentication and association processes in 802.11, and WLAN frame structure. This chapter explains different wireless attacks like war-driving, war-chalking, wi-fi signal jamming, denial of service (DOS) attack, rogue access point attack, wireless traffic analysis, MAC spoofing, de-authentication attack, man-in-the-middle attack, evil twin attack, cracking wi-fi encryptions, spectrum analysis, bluetooth devices attacks, etc. The chapter also discusses different tools used for carrying out wireless attacks or auditing wireless security like NetStumbler, Kismet, Aircrack, insider, KisMAC, WEPWedgie, WIDZ, and Snort-wireless. The chapter also discusses countermeasures against these attacks.

Wireless Cooperation

The broadcast nature of wireless networks and the mobility features created new kinds of intrusions and anomalies taking profit of wireless vulnerabilities. Because of the radio links and the mobile equipment features of wireless networks, wireless intrusions are more complex because they add to the intrusions developed for wired networks, a large spectrum of complex attacks targeting wireless environment. These intrusions include rogue or unauthorized access point (AP), AP MAC spoofing, and wireless denial of service and require adding new techniques and mechanisms to those approaches detecting intrusions targeting wired networks. To face this challenge, some researchers focused on extending the deployed approaches for wired networks while others worked to develop techniques suitable for detecting wireless intrusions. The efforts have mainly addressed: (1) the development of theories to allow reasoning about detection, wireless cooperation, and response to incidents; and (2) the development of wireless intrusion and anomaly detection systems that incorporate wireless detection, preventive mechanisms and tolerance functions. This chapter aims at discussing the major theories, models, and mechanisms developed for the protection of wireless networks/systems against threats, intrusions, and anomalous behaviors. The objectives of this chapter are to: (1) discuss security problems in a wireless environment; (2) present the current research activities; (3) study the important results already developed by researchers; and (4) discuss the validation methods proposed for the protection of wireless networks against attacks.

Increasing Demand

Due to the increasing demand of wireless networks, there is an increasing necessity for security as well. This is because unlike wired networks, wireless networks can be easily hacked form outside the building if proper security measures are not in place as wireless networks make use of radio waves and radio waves can leak outside of building at distances up to 300 feet or more. So everything we do on our network can be monitored by anyone who has wireless capabilities. This unauthorized access can be used as an essence by the hacker to launch various kinds of attacks like man-in-the-middle attacks, denial of service attacks, IP spoofing etc. As a result in addition to the firewalls, password protection techniques, virus detectors etc, additional levels of security is needed to secure the wireless networks. This paper focuses on comparing various techniques that are used to protect the users from these attacks by providing practical observations based on the network parameters time and scalability and also highlighted the best method in the end to combat the attacks at a superior level.

Ieee 802.11 Wireless Networks

In wireless network communications, radio waves travel through free space; hence, the information reaches any receiving point with appropriate radio receivers. This aspect makes the wireless networks vulnerable to various types of attacks. A true understanding of these attacks provides better ability to defend the network against the attacks, thus eliminating potential threats from the wireless systems. This work presents a series of cyberwar laboratory exercises that are designed for IEEE 802.11 wireless networks security courses. The exercises expose different aspects of violations in security such as confidentiality, privacy, availability, and integrity. The types of attacks include traffic analysis, rogue access point, MAC filtering, replay, man-in-the-middle, and denial of service attacks. For each exercise, the materials are presented as open-source tools along with descriptions of the respective methods, procedures, and penetration techniques.

This chapter shows that the security challenges posed by the 802.11 wireless networks are manifold and it is therefore important to explore the various vulnerabilities that are present with such networks. Along with other security vulnerabilities, defense against denial of service attacks is a critical component of any security system. Unlike wired networks where denial of service attacks has been extensively studied, there is a lack of research for preventing such attacks in wireless networks. In addition to various vulnerabilities, some factors leading to different types of denial of service (DoS) attacks and some defense mechanisms are discussed in this chapter. This can help to better understand the wireless network vulnerabilities and subsequently more techniques and procedures to combat these attacks may be developed by researchers.

In this modern day and age, wireless networks are everywhere. It is not a far stretch to say that it is downright crucial due to its ability to keep people connected and updated everywhere from universities and workplaces down to our personal homes. Though the benefits of wireless networks are undeniable, it also brings a new host of security concerns due to the amount of sensitive data being transmitted through these networks. A simple attack such as packet sniffing is enough to “sniff” out just enough data to cripple even giant corporate bodies if left unchecked. The aim of this research paper is to dissect and discuss the security and privacy issues of wireless networks that surround us. An interesting finding would be that wireless networks are heavily susceptible to both malicious attacks such as denial of service attacks and passive attacks like eavesdropping. It was also noted that information is more easily obtainable through wireless networks as compared to wired networks due to the ability to gleam information from long distances without having to be physically present on site. A literature review and a survey were conducted to learn about the opinions of casual users of wireless networks. The information gathered suggests that while there are many who care about privacy, they still lack the necessary knowledge to protect said privacy. These users carelessly connect to public wireless networks wherever it is available without proper precaution and care. Appropriate relevant solutions are presented based on literature study to overcome insecure wireless network usage practices in order to avoid active and passive attacks.

Performance Results

At Present, many schools have used wireless networks that are used to support wired networks. Cable network is used as an amplifier of access point to make internet access for users. The problems of networking using these cables can be a major constraint to inaccessible places that can reduce the flexibility of usage. The solution for this problem is to develop and implement Wireless Distribution System (WDS) on the access point. WDS is a system to develop wireless internet network without having to use cable as backbone for access point but to take advantage of wireless network path from access point. The parameters used in the WDS system are the parameters of jitter, througput, delay and packet loss. WDS performance can be analyzed so that will be known comparison of access point performance results with cable backbone

The Impact

A Mobile Ad-Hoc Networks (MANET) is widely used in many industrial and people's life applications, such as earth monitoring, natural disaster prevention, agriculture biomedical related applications, and many other areas. Security threat is one of the major aspects of MANET, as it is one of the basic requirements of wireless sensor network, yet this problem has not been sufficiently explored. The main purpose of this paper is to study different MANETs routing protocols with three scenarios of Denial of Service (DoS) attacks on network layer using proactive routing protocol i.e. Optimized Link State Routing (OLSR) and Reactive routing protocols like Ad hoc On-Demand Distance Vector (AODV), Hybrid routing protocols like Geographic Routing Protocol (GRP). Moreover, a comparative analysis of DoS attacks for throughput, Data loss, delay and network load is taken into account. The performance of MANET under the attack is studied to find out which protocol is more vulnerable to the attack and how much is the impact of the attack on both protocols. The simulation is done using OPNET 17.
