Ítem Seguridad en redes inalámbricas 802.11(Universidad Icesi, 2006-07-28) Madrid Molina, Juan ManuelLack of security in wireless LANs is a problem which has not been correctly assessed by network managers and people in charge of information, in spite of its seriousness. This article presents the existing technologies for heightening the security level in 802.11 wireless LANs, among with their advantages, disadvantages and application scenarios.Ítem A Survey of Attack Mechanisms on Infrastructure-Mode 802.11 Wireless Networks and Their Detection(IGI Global, 2015-01-01) Madrid Molina, Juan ManuelThe 802.11 wireless network revolution has not come without trouble. Since their creation, wireless networks have been plagued with security problems, derived from poor initial design of 802.11 security mechanisms, accelerated deployment and adoption of the technology, and lack of user education. The goal of this article is to present the reader with a survey of the currently documented detectable attacks to infrastructure-mode 802.11 wireless networks, and a proposal of mechanisms and metrics that can be used to detect such attacks. The attacks and their detection methods are divided in seven categories: Denial-of service, traffic analysis attacks, passive eavesdropping, attacks against WEP, attacks against WPA and WPA2 in pre-shared key (PSK) and Enterprise modes, and man-in-the-middle attacks.
