In case you missed it there is a really interesting story circulating on the Net, best told by Jim Louderback the CEO of Revision3 and victim of a DDOS attack over Memorial day weekend ( his Blog & CNET interview ). If you're a fan of Revision3 you already know that they got taken off-line for 3 days, if your not you may want to check out their site. They represent perhaps the best example of new Media and the future of TV, including HD video, channels, live and on-demand, etc, all delivered via the web. In order to achieve high quality video Revision3 utilizes BitTorrent technology legitimately for distributing content to users. The problem came about when a "legitimate" media tracking company identified a Revision3 server as a potential source of " questionable " BitTorrent traffic. Once Revision3 was made aware of this situation ( by a forum poster ) they appropriately locked down the server, what happened next was the strange part...

As reported by Revision3, the media tracking company ( presumably automatically ) launched a DDOS attack on Revision3's site flooding it with as many as 8,000 packets per second taking down the site by exceeding the capacity of limited web servers. Complicating the matter was the long weekend and unreachable staff at the offending company. Once they were finally able to get in contact the company stopped the attack and they both started to unravel what had happened.

The NetScaler system may not be positioned as protection from "good" guys ( vs. typical bad guys ) but this situation exemplifies why it is worth consideration as part of a comprehensive protection plan. That is why web based media companies like MSN, CNET, Digg, and many others rely on NetScaler's to protect their infrastructure. Among other features NetScaler protects sites from SYN flood DDOS attacks by handling all requests and only forwarding legitimate ticketed traffic to the web server, all other SYN flood requests are dropped before ever reaching the company Web Servers.

So for the next review of your security infrastructure, keep in mind who are the "good" or bad guys and are you protected either way.

Running Windows applications on the iPhone may not be a high priority for Steve Jobs, but for many IT users and providers the desire seems to be increasing. The recent SDK and upcoming release of the Apple 3G iPhone has increased the interest in Citrix enabling iPhone access to XenApp hosted Windows applications. We are always encouraging expanded access to XenApp from any suitable device and the iPhone appears to be a very good candidate. The great screen and touch features would provide usable viewing of apps even though they were designed for bigger screens. Plus the improved email and networking capability of the device can now make it a real contender for business use. The iPhone could be even be the " Nirvana Phone " if a new docking station was offered to provide video access to a full sized monitor plus a standard keyboard.

So the question is one of priority and market demand, where does this fit on the list of nice to have vs. must have now, and does the solution need to come from Citrix or could it be partner provided such as the Rove Mobile client for BlackBerry. We encourage your opinions and feedback.
