Abstract
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.
Highlights
Wireless networks have gained popularity in many critical areas such as in healthcare centers, hospitals, police departments, military facilities, and airports
When the stations started to communicate with the rogue access point, the data transferred were visible to the attacker
With a valid MAC address, the attacker successfully established connection with the target network and were able to use the wireless network. This shows that the MAC address spoofing attack is a trivial task in Linux systems, the MAC filtering method should not be considered as the only security mechanism to protect the wireless networks
Summary
Wireless networks have gained popularity in many critical areas such as in healthcare centers, hospitals, police departments, military facilities, and airports. It is extremely important to enhance the network security in order to protect the information that resides within the network. To achieve this goal, different security protocols have been designed, among which are WEP, WPA, and WPA2. Despite the presence of these protocols, security is still the main concern in the wireless networks. Air transmission is a vulnerable medium, and it provides opportunity for the attackers to intercept the information that will be later used to launch different types of attacks. It is important to know different kind of security attacks in order to defend the networks against the attacks and to guarantee the reliability of the wireless networks
