Citrix’s Application Delivery Controller NetScaler is enabling organisations to take the first steps towards Software-Defined Networking (SDN), according to Citrix CEO Mark Templeton.

Speaking at the Citrix Synergy conference in Los Angeles, Templeton said that NetScaler is the company’s fastest-growing product, because it delivers a mobile experience for some of the world’s largest websites and enterprises, such as Amazon and Betfair.

It also runs at “cloud scale”, delivering over 1.4TB of throughput in one cluster, allowing customers to consolidate delivery services on a single platform.

In particular, the Netscaler SDX platform has been “growing like mad” because it enables enterprises to move to a more consolidated and converged infrastructure, providing application-defined controls and automatically applying policies on the physical parts of the network.

“When I think of this product, this is the SD in SDN,” said Templeton.

Graham Melville, director of product marketing for Citrix cloud networking, explained that NetScaler works a bit like a telephone operator, inspecting packets as they come over the network and sending them to the right server.

It also makes servers more efficient through load balancing, and includes a wide range of security features for blocking malware and distributed denial of service (DDOS) attacks.

“People think of us as a network appliance, but we actually work at much higher levels of the network. So Cisco and Juniper do the Layer 2 and Layer 3 stuff, whereas we’re right up at Layer 7, looking into the actual applications,” said Melville.

“That’s where things like the app firewall are. Network firewalls aren’t going to stop anything, because it’s HTTPS traffic so everything’s going to come through – good or bad. That’s why you need to go higher up in the application layer and look to see more deeply what’s going on.”

NetScaler is central to Citrix’s new Worx Mobile Apps offering, which allows any application to connect to backend infrastructure securely via a micro VPN. Melville said that NetScaler enforces the security, and the micro VPN is used on a per-application basis to secure the traffic.

Citrix recently added a new feature called HDX Insight, which gives IT departments in-depth visibility into all the traffic that passes through NetScaler. This makes it easier for users to troubleshoot application performance problems in complex network and data centre environments.

Of course, administrators have long had command-line tools, such as ping and traceroute, to diagnose network problems. HDX Insight was designed for administrators unfamiliar with such tools, especially those with more experience supporting applications than networks.

“This allows the help desk guy, who doesn’t know anything about networking, to be able to know if a problem is a network issue or an application issue,” Melville said.

ImaSight, a maker of digital X-ray imaging systems and software for chiropractors, and NexySoft, an EHR clinic management software developer, are pleased to announce the full integration of their respective technologies.

“We are thrilled to integrate our digital X-ray technology with yet another EHR total practice management software solution,” said Steve Johnston, vice president and co-founder of ImaSight. “NexySoft is helping healthcare professionals all over the world reduce their paperwork and automate daily tasks, and now those same professionals have the ability to seamlessly integrate the handling of digital X-rays directly into their workflow.”

Now that integration has been achieved, NexySoft users can avoid having to re-enter patient data (reducing errors), process patient X-rays faster, incorporate and view annotated X-rays from directly within their EHR system, and attach X-ray images directly to patient files.

ImaSight’s digital X-ray systems empower chiropractors to go beyond talking to their patients, and give doctors the ability to communicate with them by providing the patient with annotated X-rays, illustrating both diagnosis and prognosis.

“Our software has helped numerous healthcare practitioners manage small, medium, and large volume clinics in the effort to serve their patients better and to increase their clinic’s efficiency” commented Jean-Luc Trépanier, president and founder of NexySoft. “We are excited to integrate the digital X-ray technology from ImaSight, a proven leader in the digital x-ray market, and provide our clients another avenue towards automation and the streamlining of efficiencies.”

Because malware peddlers often bundle their malicious wares with legitimate software, downloading anything from unofficial download sites is a bit like playing Russian roulette: a click and the game is over. Of course, you won’t die, but you won’t be happy with the results.

Microsoft researchers shared the example of a password-stealing Trojan bundled up with a game tool used for customizing the massively popular Dota2 Warcraft battle arena mod.

Made by an unknown third party and offered for free on an unofficial site, the tool works but the malicious bundle also drops and runs the Trojan, which then begins to harvest stored passwords for a variety of FTP and IM clients and web browsers. The stolen passwords are then encrypted and sent to the bundle author either by email or FTP.

To show you how easy this malicious bundling is done, the researchers have tracked down the malware builder tool used in this case, which is publicly available for download and obviously geared towards Russian-speaking users.

“Once a trojan is created with the builder, an author can choose to bundle the malware with legitimate tools, software or images”, they point out.

The final product (bundle) is usually distributed via download sites, and the link to the download page sent out by email or comment spamming.
