With the implementation of the 802.11ac standard, we see a significant improvement in how RF spectrum is used. In many ways 11ac picks up where 802.11n left off by building on many of the successful techniques used by 11n. With 11n we saw a number of very clever techniques introduced such as frame aggregation, MIMO and wider channels that effectively made more effective use of the RF spectrum. With 11ac we see enhancements to a number of innovations introduced by 11n plus one new feature, MU-MIMO, which is a radical departure from anything found in previous 802.11 standards.
This paper will introduce 11ac features, offer some guidance to those who are considering upgrading to 11ac, discuss deployment considerations, and provide an overview of AirTight Networks’ first 802.11ac access point, the C-75
The latest addition to the IEEE 802.11 standards stable is the 802.11ac standard, which is the next evolutionary upgrade to the standards helping us to achieve better data transfer rates and enhanced performance with our Wi-Fi networks and devices. This document highlights the main technical points in the 802.11ac standard and justifies the use of these features to improve performance.
The Wi-Fi space has seen tremendous growth in terms of its widespread usage as well as its performance capabilities.

This paper presents a vulnerability, called Hole1961, in the WPA2 protocol that makes all implementations of WPA- and WPA2-secured Wi-Fi networks (regardless of the authentication and encryption used) vulnerable to insider attacks. It discusses ways in which a malicious insider can exploit Hole196 to attack other authorized Wi-Fi users in a WPA2-secured wireless LAN (WLAN). It also explores remediation strategies at various levels that organizations can implement to mitigate this threat.
A soft access point (AP) is a laptop or other wireless enabled device which performs traffic forwarding between its wireless interface and some other interface which is connected to the secure network. A soft AP can show up as rogue access point on the enterprise network. This can happen inadvertently. A soft AP can, however, be maliciously installed as it is perfect hacker "solution" to put a rogue AP on a network while evading wire-side controls such as 802.1x, NACs and wiresideonly rogue AP scanners.
Using Virtual WiFi, Windows 7 laptops can now be connected to your enterprise Wi-Fi network while sharing their enterprise network access with other unauthorized Wi-Fi devices or users.
This means that every Windows 7 laptop is a potential Rogue AP1 that can be used to bypass your wired security and access your private enterprise LAN. Using a Rogue AP, an attacker could compromise your servers, access sensitive data, and launch network reconnaissance and disruption attacks.
WiFi is proliferating fast. The convenience of wireless access, low cost, and plug-and-play nature of the technology have been the major drivers for WiFi's popularity among home Internet users. Lately we are also seeing an increasing adoption of WiFi in the enterprise. More and more businesses are rolling out wireless LANs to cut costs and increase productivity. Today all laptops, PDAs, and smartphones have WiFi built in. WiFi hotspots, spanning coffee shops, hotels, airports, or even cities, are mushrooming to meet the growing demand of WiFi Internet access.
Understanding the PCI DSS Wireless Requirements
The Payment Card Industry Security Standards Council (PCI SSC) has published a PCI DSS Wireless Guideline which acknowledges that wireless is a clear and present danger to network security and those who collect, store or transmit card holder data must take steps to assure that it is secure, whether or not wireless is deployed in the cardholder data environment. Though the PCI DSS already included wireless security requirements, this is the first time that the requirements for wireless security have been described unambiguously for all cardholder data environments (CDE). Organizations which handle payment card data must take steps to secure the CDE against wireless threats including unmanaged and unknown wireless devices in the environment and must scan all locations. This white paper helps those organizations understand how the PCI DSS 1.2 wireless requirements apply to them, how to meet those requirements in a cost effective way, and how to secure your network and cardholder data from wireless threats.

While at first glance, Sarbanes-Oxley would seem to have very little to do with IT departments and network security, closer study reveals that it actually has major impact on IT departments and IT security in particular. Since IT underlies the very business of recording and reporting all financial activity, it follows that a lack of control over IT security would imply a lack of control over the organization's financial reports, in direct violation of Sarbanes-Oxley section 404. When a wireless LAN is part of the network infrastructure, it too must be subject to the strictest controls to ensure the credentials of those using it. This whitepaper addresses the implications of Wi-Fi technology on public corporations, and reveals the dangers of Wi-Fi threats to public financial data integrity, even if the corporation has a strict 'no Wi-Fi' policy. It also describes how the AirTight SpectraGuard Enterprise Wireless IPS can be implemented to protect against these threats and ensure compliance to SOX.
