A CounterSpy Enterprise User Talks

"Just wanted you to know that we are still using CounterSpy as an integral part of our network and desktop security enforcement. At first the scans produced a large number of trojans and other potentially and known dangerous threats on the systems. Setting the Agent responses to the different levels was very easy. Also having the option to allow specific applications is a great feature, which is also very straightforward. The automatic daily scans find the occasional intruder and faithfully delete or quarantine, send out notification just as the script is written. It's great to have a product on the network which is doing the job that it is marketed to do. Kudos to you and your application team for a great product. -- Daniel Bruen

Two (Very Long) Quotes of the Week!

"The displacement of the idea that facts and evidence matter by the idea that everything boils down to subjective interests and perspectives is -- second only to American political campaigns -- the most prominent and pernicious manifestation of anti-intellectualism in our time." -- Larry Laudan.

"A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects." -- Robert A. Heinlein

Tech Briefing

Trojan Targets Mac Users

Dan Kaplan from SC Magazine reported: "Apple users, your days of worry-free clicking could be numbered. A Macintosh Internet security and privacy software maker has discovered what is believed to be the first professionally-crafted in-the-wild malware targeting the Mac operating system. The trojan, a DNS changer that can be used to hijack search results and divert traffic to the hacker's website of choosing, has been spotted on numerous pornography sites, according to Intego. Attackers attempt to navigate users to the malicious sites through comment spam posted to Mac forums. The trojan masks itself as a QuickTime plug-in.

Security experts said the discovery is proof that cybercriminals are beginning to consider the Mac a financially viable vector for attack. Alex Eckelberry, president of Sunbelt Software, said hackers likely were spurred on by the release of the iPhone and iPod Touch, which generated millions of new Mac OS X users.

"The economic motivation for the Mac has reached the tipping point," he told today. "The Mac is emerging as a more widespread platform in general. I think Mac users need to get off their complacency about Macs being safe." Talk of malware for Macs has been a quiet subject since early last year, when a proof-of-concept virus appeared that spreads via the iChat instant messaging system. An Apple spokeswoman did not immediately return a call for comment. More at:

Windows Server News

What Is Application Virtualization?

WServerNews subscriber Bill Prehl and I discussed this virtualizing apps and I asked him to write an article, explaining this very interesting technology. Here it is:

"Application virtualization is a concept of creating a "bubble" inside the operating system just for the application. In addition, products like SoftGrid originally developed by Softricity but now owned by MS add other related elements of behavior such as thin-client "push" technology.

First of all, virtualizing an application can mean several things. Most importantly it means the removal of DLL-hell. So many IT administrators are still very frustrated with the DLL requirements for applications to operate properly. This is predominantly a Microsoft Windows issue. But, not to make Microsoft the entire bad guy Sun Microsystems also has an issue with the Java Runtime Environment (JRE) when running old and new versions on the same machine. Having two JRE's running on the same system at the same time is very difficult, if at all possible.

A developer, in particular, would like to run their app in the older JRE's but usually has to have more than one workstation running to perform this test. With Application virtualization we can run both JRE's at the same time on the same machine. In fact, the same application can, itself, run in both JRE's at the same time. The unique features of App Virtualization is shared information (e.g., registry keys, property files, etc.) which are also virtualized so there is no file dead-lock issue or settings competition or confusion. Plus, both can make changes to the files or registry keys and there are no conflicts. Lastly, the changes are virtual - meaning they do not permanently stick to the machine's hard drive so upon reboot we find them still lingering.

Secondly, App Virtualization using SoftGrid can provide a mechanism to push applications to users that need the app. The administrator can provision that certain applications be available to certain users and/or workstations. In addition, the technology will push only the required information (reg keys, application execution and settings files, etc) just to get the application started. Even if the application requires more files once up and running, App virtualization can provide the additional files on the fly. This provides an excellent opportunity for remote users on low-bandwidth (or encrypted VPN sessions) to use the latest version of the app without having to download and install. On top of this, the user could have their own "local" version of the application but also use the virtualized version if needed, at the same time if necessary. This concept provides fundamental licensing control and up-to-date applications without having to keep a nightmare of software inventory agents running to constantly update a database of software and workstations.

Another plus is that the user can gain access to their applications while out of the corporate environment. Taking this a step further would be allowing to run apps over the web via a web browser. This then allows the concept of using a public machine for private corporate information and applications. And again, when the machine is rebooted all evidence of the application is gone. How does that sound for a web browser that inadvertently downloaded a few spyware applications?

So, summing this up, Application Virtualization is a strong solution to pushing applications to users on high and low-bandwidth connections, using effective software licensing and software updating, and removing software version conflicts. I believe this is a sleeping giant of a solution for a lot of network and system administrators but since Microsoft has purchased Softricity who created SoftGrid there has been little marketing about this technology. Parts of SoftGrid are going to be included in Windows Server 2008 and the associated server management tools so I strongly urge people to check out this technology. It just might be your diamond in the rough. -- Bill Prehl
