Roundup: Security & Chips

AirDefense's New Look: Wireless LAN security startup AirDefense Inc. has revamped its security and sniffing tool -- AirDefense Mobile 4.0 -- with a new graphical interface designed to make it easier for network administrators to pick up threats to the enterprise.

The company has also upgraded the "brain" of the system, called the analysis engine, so that it can email or message remote administrators with more than 100 different security and performance alarms.

For users who want to take security outdoors, the firm also offers a long-range card and antenna setup. The hardware kit includes a high-power 802.11a/b/g wireless card with external antenna capability. The hardware kit bundled with Mobile 4.0 will be available mid-August and retails for $1,695.

Makin' MIMO: Both Atheros Communications Inc. (Nasdaq: ATHR) and Broadcom Corp. (Nasdaq: BRCM) are pushing their high-speed pre-802.11n chipsets in separate announcements today.

The upcoming 802.11n specification is based on multi-antenna technology called MIMO (multiple input, multiple output), which should more than double the data transfer speeds offered over today's WLAN networks, with rates of 200 Mbit/s or more. Many vendors are jumping the gun on the faster specficication with pre-n chipsets available now.

Broadcom has scored a deal with laptop maker Acer Inc. Meanwhile, Atheros claims that it has three as-yet unnamed notebook makers lining up to use its pre-n offering. The startup has developed a mini-card that is the first in the industry to achieve PCIe compatibility certification. The firm says this will speed the design process for manufacturers.

Sybase's Gated Community: Mobile software provider Sybase Inc. is promising users a more secure method of deploying mobile software in the enterprise with its new secure relay architecture due later this quarter. The firm says that the product, called OneBridge Live, will enable enterprises to push data to mobile devices without opening inbound server ports or firewalls. The secure link will allow data to be pushed to devices from a hosted server or machines outside the organization without staging data outside the firewall.

The security update is part of Sybase's modular updates to its mobile management software. (See iAnywhere Bundles Up.)
