Ashworth Instructor Discusses Why IT Professionals Are In Demand!

Tuesday, March 25th, 2008


                   Thanks to פיקוס for permission to use this Photo.

If you are in the IT Field or considering getting into it, you don’t need rose colored glasses to see a promising future for yourself.  The Bureau of Labor Statistics recently reported that IT will be the fastest growing sector of our economy for the next ten years.  They also report that the three fastest growing jobs in the US are network system and data communication analysts, computer systems analysts and software application engineers.  In fact, in just about any top ten list, you will find IT has the most positions of any field.Now couple this tremendous growth with the following statistic:

The labor force for the 25 to 54 age group in IT will only grow at a dismal .2% between 2006 and 2016. 

Do you want to be in demand for the next decade?  Stay committed to your program studies and your hard work will pay off.  The bottom line is that it’s important to obtain as many skill sets as you can in the rapidly expanding IT industry.  If you need assistance with your lessons, I encourage you to reach out to me in the comments section of this blog.  I always look forward to hearing from my students!

IT Goes Green!

Thursday, March 20th, 2008

 
         Thanks to Isaac Wayton for permission to use this Photograph.

IT has already been paying close attention to the green revolution as it applies to technology.  Last year, the Chief Network Engineer for Google came out with a startling quote, “If the performance per watt of today’s computers doesn’t improve, the electrical costs of running them could end up far greater than the initial hardware price tag.”  Consider that while a typical server in the 2000 consumed only 100W of power, the average server today consumes at least four times as much.

To compound this, the number of servers in networked organizations has expanded drastically in the past decade as the ccommon practice up to now for server management was to allow rack-mounted servers to run just one workload.  This is exemplified by a 2005 study by Stanford University that showed that Servers in the United States and their attendant cooling systems consumed 45 billion kilowatt-hours of energy in 2005. That’s more than Mississippi and 19 other states. 

Now factor in the exploding economies of China and India and the number of servers they are putting on line each day and one can easily recognize the strain on resources that the IT industry is levying on the world.  It leaders across the country are recognizing that the current network model is unsustainable in the years ahead under realistic budgetary constraints.  Energy consumption is one more reason why more and more organizations are turning to virtual servers, centralized storage and virtual or multi-user desktops.

Ashworth University Instructor Discusses What Every IT Professional Needs To Know About KVM Switches…

Monday, March 17th, 2008


                 Thanks to Kit Cowan for permission to use this Photo. 

I had to go about shopping for a new KVM switch at my work to replace one that had gone bad.  This gave me the idea to write a short blog piece about KVM switches.  A KVM switch allows a user to control multiple servers or workstations with a single monitor and mouse/keyboard.  In a typical datacenter, each rack of servers will be connected to a KVM switch which has an assigned monitor/mouse/keyboard.  Because of KVM switches, organizations don’t have to purchase a monitor and keyboard/mouse set for every single machine.  This makes sense since users do not dedicate themselves to a server desktop as they do a workstation. 

Each computer is connected to the KVM switch with a special VGA or USB cable.  Higher end KVMs allow standard Ethernet cables to connect computers.  KVMs usually come in 4, 8 and 16 port versions, meaning that it can accommodate that many machines.  When a user wants to access a particular machine, he simply hits an assigned key on the keyboard to view a menu of the computers that are managed by that KVM.  He then selects the machine he wishes to view and the monitor then brings it up.  Imagine if you were downloading and installing Windows Updates on 8 servers.  You could pull up each server at a single monitor and complete the tasks without leaving your chair.

KVM switches are not utilized as much as they have been in the past due to the ease of tools such as Microsoft Remote Desktop which allows one to remote into any windows server at will and pull up the server desktop wherever they are in the world.  These remote applications due have one big limitation in that they do not allow a user to view the booting process of the server or access the BIOS as one normally is able to.  Unlike a KVM, if you reboot a machine while remoting into it, you lose your connection.  Because of this, KVM switches continue to be a valuable tool for networks today.

One of the biggest players in the KVM market is Avocent.  Visit their website at www.avocent.com to learn more about their product line and KVMs in general.

Bill Gates On University Tour To Discuss The Coming IT Labor Shortage…

Friday, March 7th, 2008


            Thanks to Dennis Hamilton for permission to use this Photo.

Bill Gates toured five North American Universities in February speaking about the coming IT labor shortage.  Across the country, colleges across the U.S. and Canada have seen a steady drop in the number of students entering the field of computer science ever since the dot com bust at the start of the decade.  K12 schools as well are seeing fewer students interested in the field of IT.  These indicators point to a looming shortage of skilled workers in the IT field in the coming decades.  Although this will greatly benefit those in or just beginning their careers in IT, it puts into question the leadership in technology that the U.S. has enjoyed up to now. 

In order for our country to continue to be a major economic player in the world we must have the IT talent to spur further technological innovation and support our current and future infrastructures.  It is because of this dire possibility that leaders such as Bill Gates are publicly addressing young people concerning the exciting possibilities and unlimited opportunities that await them in the IT field. 

So how did this come about?  There are several factors.  The dot com bust of 2000 did a lot to taint the field.  Many high school students changed their minds about IT after reading how many IT jobs were lost during that time.  Parents discouraged their middle and elementary aged students to pursue the field as it offered little promise of opportunity they thought.  The overplay of the media discussing the many IT support jobs that migrated to India also provide fodder to parents and young people to not consider IT.  Unfortunately though, these concerns have been exaggerated and now the pendulum has swung so far in the other direction that those in the IT field today have the benefit of knowing that their skills are and will continue to be in high demand.

Microsoft To Increase The “Openness” Of Its’ Products. Really?

Tuesday, February 26th, 2008

if you don't know, you better ask somebody: freezy freakies ya'll!

In a surprise announcement, Microsoft vowed to increase the openness of its key products!

Yes this is still February, April 1st is several weeks away yet!

So what did Microsoft say in this release? Well,

Specifically, Microsoft is implementing four new interoperability principles and corresponding actions across its high-volume business products: (1) ensuring open connections; (2) promoting data portability; (3) enhancing support for industry standards; and (4) fostering more open engagement with customers and the industry, including open source communities

Several times in the last few years I have advocated for Microsoft to Open Source Windows and Internet Explorer and while this announcement doesn’t go that far, it does seem to be a step in the right direction.

According to Microsoft’s CEO-in-waiting and current Chief Software Architect, Ray Ozzie

“Customers need all their vendors, including and especially Microsoft, to deliver software and services that are flexible enough such that any developer can use their open interfaces and data to effectively integrate applications or to compose entirely new solutions,” said Ozzie. “By increasing the openness of our products, we will provide developers additional opportunity to innovate and deliver value for customers.”

The Microsoft products this refers to are Windows Vista (including the .NET Framework), Windows Server 2008, SQL Server 2008, Office 2007, Exchange Server 2007, and Office SharePoint Server 2007, and future versions of all these products. (more…)

Ashworth Instructor Discusses The Dangers Of Using Default Passwords…

Wednesday, February 13th, 2008


               Thanks to radiorover for permission to use this Photo.

The following interview with Robert Moore illustrates the apathy that is still amazingly apparent in the IT industry today despite the strong awareness of IT vulnerabilities and the importance of tightening security for all organizations and even home users.  It also shows how easy it is for even computer novices to break into network devices.   

A quick Google search for sites showing the default passwords for just about any computer or network device sold on the market in the past decade can be easily found.  Many of these sites are not developed for malicious purposes.  The fact is that network devices are constantly resold and recycled.  This requires that the device be reset to its default configuration to erase the settings made by the original owner.  In order for the new owner to configure the device, he or she must know the default password credentials in order to access the device.  Because the original device documentation is often missing, these default password sites are vital. 

These sites make it even more important to immediately change the password for any newly purchased network device.  Recently, I heard a high school student inform me that he regularly accesses his neighbor’s wireless router by using the default logon for the device.  By doing this, the student can use his neighbor’s DSL connection for free.

Safari-Webkit Is Fast, Very Fast!

Monday, February 11th, 2008

safari_beta_homepage_tn

I just read Computer World’s glowing review of the latest Webkit deveopmental build.  If you’re not familiar with Webkit, it’s an open source web browing engine that’s been “buzzing” around the I.T. industry.  It’s somewhat confusing to understand at first, but Webkit is also serves as the developmental version of the engine used in Safari.  As the review indicates, Webkit runs at a considerably faster rate than Firefox 3, Internet Explorer, Opera, and Safari’s standard browser.  I highly recommend that you keep a close eye on Safari-Webkit’s every development.  I’ll keep you updated on our blog, so be sure to check in frequently.  Take care.

Ashworth Network Security Instructor Reviews 2008’s Top 10 Cyber Security Threats…

Monday, February 4th, 2008


              Thanks to foundphotos for permission to use this Photo. 

The SANS Institute, an organization dedicated to computer security training, certification and research recently released their Top Ten Cyber Security Threats for 2008.  Below is a summary:
           

  1. Attacks via web browser vulnerabilities, particularly plug-incomponents such as QuickTime and Flash.  Many of these plug-ins are rarely updated. 
  2. The growing sophistication of Botnets.  The most popular exampleis the Storm Trojan which accounted for one in twelve virus infections only a week after its release.  This new breed of botnets uses peer-to-peer control rather than a centralized controller that can be eliminated. 
  3. Cyber espionage, particularly economic espionage conducted bynation states 
  4. As Mobile phones are become general purpose computers, worms,viruses, and other malware will increasingly target them 
  5. Insider attacks by rogue employees, consultants and contractors.These threats will result in the further limiting of the cyber rights and abilities of employees. 
  6. Identity theft performed by persistent bots.  These bots notonly target email addresses, bank accounts information and passwords but even the cyber behavior of users that can be later used forextortion. 
  7. Increasingly malicious spyware 
  8. Web Application Security Exploits are constantly being targetedas so many applications today are web based and can be targeted by hackers. 
  9. Social Engineering continues to be widely utilized.  Phony taxscams are very popular today. 
  10. Infected Consumer Devices such as USB drives that can containmalicious code or espionage based applications that can attack acomputer in a matter of seconds when the USB drive is inserted into a computer.

Free Kaspersky Anti-Virus Software Is Effective And Worth A Look…

Tuesday, January 29th, 2008


                Thanks to entropy for permission to use this Photo.

Kaspersky Anti-Virus is one of the most effective anti-virus programs I’ve ever come across. Not only it has good detection rate, it’s light on the system memory too. I was happy to see that Kaspersky has released the free scanner for the users. However, please note that this is just an on-demand scanner and it won’t clean the virus or remove it for you.

Now the question rises that why do you want to use it, when it can’t clean or stop viruses and here’s the answer to this tricky question :Well, I always vouch for having two anti-viruses on a system! (C’mon linux fans, you have a chance to speak) I know that most of the anti-virus firms say that it’s not good to have to anti-virus software but let me make my statement a little bit clear. It’s always good to have one full anti-virus software which runs in real-time, however it’s even better when you have an anti-virus software whose real-time scanning should be disabled and runs as an on-demand scanner.
