Are you ready for emerging threats?

Are you ready for the next wave of cyber attacks? My guess is probably not. How could you if you don't know what's coming?

You see, I have a really bad feeling about the next couple of years, at least as far as the technology field. We will continue to see cyber threats making huge leaps and bounds as malware writers continue to become well funded, organized operations. In the "old" frontier days of spyware, you pretty much only got the really nasty spyware/malware if you went somewhere on the web that you probably shouldn't have in the first place. That's already changing, as we see malware writers are now beginning to target ANY website that they can crack into and place their malware distribution software on. That means that even the knitting blog that your grandmother visits isn't safe anymore. And your uncle's website where he sells fishing lures is now a target, since his website was built three years ago with an e-commerce package that now resembles swiss cheese to a determined malicious hacker. These newer malware packages are also getting smarter about avoiding detection.

I'm not even to the good part yet. Unfortunately Microsoft Windows Vista has been a big flop and proven that it's not really ready for prime time mass adoption. It's unfortunate because it would be a welcome scenario if a larger installed base of users had a more secure operating system and more secure browser. The new Windows Service pack 3 for XP will do some good as far as security goes, but without User Account Control, it still isn't as secure as Vista.

A recent high profile "pwn to own" contest showed us that operating systems are more hardened and less vulnerable than ever before. None of the base operating systems were hacked on the first day. On the second day, hackers were allowed to go after bundled software on the system, such as web browsers. Apple's Safari web browser on the Mac platform was hacked by going to a prepared website where the hacker had prepared an exploit for an unknown vulnerability. The third day the hackers were allowed to go after third party installed software, and the Vista PC was compromised by an exploit with the Adobe Flash player software, a very ubiquitous add on that anyone needs to view most sites on the internet. This showed us that while browsers are still a target, no matter what operating system you are running, common applications running on computers are going to be the next thing that malware writers attack. I know most of you are well trained by now to perform your operating system updates, and web browsers, but are you prepared to keep track of every application that runs on your computer and keep every one up to date? You need to start getting used to doing that now.

So what can the Small Business owner/IT department/Consultant do to prepare yourself for these threats? Enforcing strict user policies and locking down computers so that end users can do the least damage should be high on your list. I know, user will cry and moan, but it must be done. Make no mistake, USERS SHOULD NOT HAVE ADMINISTRATIVE RIGHTS to their local computers. That point is so important, I feel it should be repeated. I repeat, USERS SHOULD NOT HAVE ADMINISTRATIVE RIGHTS to the local computer. More than ever, KEEPING SECURITY SOFTWARE CURRENT is another top priority. Consider ADDING A UTM (Unified Threat Management) device to protect your network, such as the ones made by Astaro. Such a device will allow you to FILTER INTERNET CONTENT, which is a good idea for many reasons, including security.

No matter what steps you take, you can never be 100% secure. But by taking practical steps you can be prepared to face new cyber threats with the confidence that you computer systems are not easy pickings for malware, malicious hackers, or identity thieves.

Where's my RAM? or How I learned to work in 64 Bits Part 3

After much trial and error, I've finally gotten my x64 Windows XP Pro install completely stable (for Windows that is :)

One casualty in the war for system stability was unfortunately my brand new Nvidia graphics card. Shame on you, Nvidia!!! Why can't you write a stable driver that actually allows 3d to work on my x64? Alas, the onboard ATI fared better. I was able to resolved some BSOD issues on shutdown as well as random lockups by downloading the latest (not even beta!) ATI Cataylst drivers.

Unfortunately this sort of thing isn't limited to Windows XP x64. Join me into my jump into Windows Vista 64 bit.

Where's my RAM? or How I learned to work in 64 Bits Part 2

I haven't had much working from home time the past few days, and with the fall season of TV shows like Heroes, Chuck, and House 'playing' around time has been greatly reduced. I'm sad to report that I'm having driver stability issues. I was using the latest beta Nvidia drivers for x64 and now I'm having screen blanking and non responsiveness. At least they actually provide 3d graphics! But at the expense of system stability? No thanks.

So, I'm going to give up the option of running games on my x64 machine(for now anyway) and focus on Virtualization software and my productivity apps. So it's Microsoft Virtual PC, VMWare Server and the standard stuff, Office 2007, web and graphics apps.

The reports of Windows XP's death are greatly exaggerated

Windows XP has officially received a stay of execution. You will still be able to purchase XP home and professional until June 30, 2008. OEM's and system builders will be able to keep bundling Microsoft's best OS until January 30, 2009.

So does this mean that Vista is a flop? Well, I can tell you that I get people asking me the question whether they should downgrade to XP, as they are having issues with Vista. Time will tell if Vista really is "ME2" or not.

Where's my RAM? or How I learned to work in 64 Bits Part 1

I built a new computer this month. It's got the most RAM of any system that I've personally owned. Here's the specs:

Amd Athlon 64 X2 4600+
4 Gigs Ram DDR2 800(4x1Gig)
gigabyte motherboard
PCI Express GeForce 8500GT 512 Meg
Misc hard drives I have laying around that I will be swapping out

I first installed Windows XP(32bit) Professional. I could only see 3.5 Gigs of ram, give or take a couple hundred meg. I was aware of this limitation, but it got me thinking about really wanting that extra RAM available. I am testing out some different Server Operating Systems on both VMWare Server and MS Virtual Server. So I decided to install Windows XP Profesional x64 Edition, the 64 bit version of Windows.
