“…Next, Nikita Borisov, Ian Goldberg, and David Wagner at the University of California, Berkeley, independently found the same problems as well as new ones [37]. Arbaugh, Shankar, and Wan at the University of Maryland identified flaws in the access control and authentication methods in 2001 [38]. Fluhrer, Mantin, and Shamir broke the mode in which RC4 was being used in 802.11 [39], and finally Arbaugh and Petroni demonstrated that the mitigation technique to prevent the Fluhrer attack actually made the problem worse [40].…”

“…In many cases, wireless solutions were adopted and implemented without due consideration for the information security risks introduced (Arbaugh et al, 2002). Many organizations implemented wireless networks as an extension to existing wired networks, with default settings, resulting in "open" networks.…”

Corporate governance is generally regarded as the means by which an organization should be directed and controlled. According to good corporate governance practices, an organization should maintain a competitive advantage by securing its assets and protecting against new threats introduced through new technologies. An example of a new technology that is being increasingly implemented in organizations is that of Voice over Internet Protocol (VoIP). VoIP is typically seen as a replacement for the Public Switched Telephone Network (PSTN) and converts analog voice into digital voice packets for transport on computer networks. VoIP implementations are on the increase due to its many benefits. However, the focus of VoIP implementations is typically on the advantages and not on potential risks. This oversight could affect corporate governance as due care and due diligence may not be assured. This paper will investigate a possible way of making organizations aware of these information security risks through the development of a VoIP Risk Table, which will correlate the risks, threats, likely impact, recommendations and COBIT 5 process practices related to VoIP by means of a qualitative content analysis. This table could assist organizations with proper risk management for VoIP implementations enabling organizations to take the necessary steps to mitigate risks and ensure better governance of VoIP technologies.

“…The initial approach to WLAN security was called Wired Equivalent Privacy (WEP) and proved to be a security disaster [3]- [6]. Later, IEEE 802.11i [7] and the related WPA and WPA2 provided more substantial authentication, integrity, and confidentiality protection.…”

Abstract-Network communication using unprotected air as a medium leads to unique challenges ensuring confidentiality, integrity and availability. While newer amendments of IEEE 802.11 provide acceptable confidentiality and integrity, availability is still questionable despite broad usage of Wi-Fi technologies for tasks where availability is critical. We will present new security weaknesses that we have identified in the 802.11 standard and especially the 802.11h amendment. Our results are underlined by an extensive analysis of attacks addressing the quiet information element and channel switch announcement in management frames. For some stations a complete DoS effect can be achieved with a single packet for more than one minute. This shows that the newly identified attacks are more efficient than earlier approaches like a deauthentication attack. Tests were performed with a large variety of network interface cards, mobile devices, and operating systems.
