The management of updates has become an essential element in overseeing a computer network today. Take the network that I manage for the school district I work for. Being a Windows based network, our 90 servers and 5500 workstations rely on Microsoft update which are made available from Microsoft every second Tuesday of the month for the most part. Critical updates are made available on an as needed basis such as a hot fix or the plugging of a security hole that has been exposed.
When I first entered the networking field, these updates had to be managed on an individual computer basis much like your home computer. This of course was very labor intensive. It also ate up a lot of your Internet bandwidth as each and every machine had to communicate directly to the Microsoft website. Today, most windows based networks of any size utilize a Windows WSUS server, (Windows Software Update Services) which download s all available updates and then dispenses them throughout the network during off peak hours. See the link for more information: http://technet.microsoft.com/en-us/wsus/bb466193.aspx
The most common types of updates are for antivirus and anti spam applications. Ensuring that these types of updates are downloaded and installed throughout the network is of the utmost importance. Viruses can spread across the world in a matter of hours and can bring down critical servers or even an entire network unless AV applications are current.
Like most schools and many other types of organizations we have a web filter. Nearly every night, the filter downloads the latest site category updates. To explain, a filter company constantly discovers new sites across the Internet for categorization and will return to previously visited sites to discern if the site needs to be recategorized.
We have dozens of applications such as our backup software that regularly download updates as well. In addition, all of our servers are from Dell, which periodically (about once a quarter) sends out a CD with hardware and BIOS updates for its machines.
There are not many people who can seriously put into question the projected dominance of Google search technology in the future evolution of the Internet. Through his brilliantly engineered software architecture and conceptual maps of its' potential applications, supergenius Tim Berners-Lee, the acknowledged inventor of the World Wide Web, has for years been carrying his message of a "semantic web" that will make the current incarnation of the web seem look like your Dad's Rolodex by comparison.
In Berners-Lee vision, the next generation of web technology will be semantic, i.e. all data will be interconnected and capable of communicating with other "information" through a common language so speak. The following article discusses the development of the semantic web alongside the related, but not parallel development of Google’s search, mapping, and tracking applications. Berners-Lee is not anti-Google, but he is passionately against the centralization of web data and any form of proprietary control over Internet content.
I also encourage you to check out this very insightful video presentation in which Berners-Lee takes you on a virtual tour of the Web from its’ beginnings into tomorrow. This is fascinating stuff. Please share your thoughts with the Ashworth Blog community after brainstorming on your own.

Have you seen the recent commercials from Verizon Wireless touting their wireless service, contrasting their service with the seemingly restrictive confinement of WIFI. This is part of a battle for wireless dominance. WIFI is the current wireless standard leader. If you have a laptop, chances are you have some sort of WIFI router device in your home to provide WIFI access for it and other devices in your house such as the newest IPOD release. You have probably utilized the WIFI offerings of a local coffee shop or hotel (I couldn’t imagine staying in a hotel today that didn’t offer WIFI or at least Ethernet network access). If you download a free program called NetStumbler and install it on a computer that has a wireless card, you can discover wireless access points wherever you are. The program makes a sound every time a new WIFI point is discovered. Driving around with your laptop running NetStumbler can make your computer sound like a video game as it will sound off repeatedly like a machine gun as it find the plethora of WIFE points in the area.
The problem with WIFI is that it is spotty and not predictable. WIFI has a limited range and many WIFI hotspots are now guarded with security such as WPA, disallowing public access. This has created a demand for a more streamlined wireless standard that offers blanket coverage.
One option is the cell phone companies such as Verizon. These services can offer as much as much as 3.5 Gig of network throughput, putting WIFI to shame. WIMAX is another option in which metropolitan areas can offer blanket coverage throughout the area with speeds up to 4 Gig. Both of these offerings work on some sort of subscription plan which can cost as much as $60 a month. Unlike WIFI, each and every device must have a separate subscription, making these alternatives very expensive. Over a dozen metropolitan WIMAX projects have been dismantled over the past year due to higher than predicted costs and a shortage of willing subscribers. WIFI has also fired back with the new 802.11n WIFI standard this year which offers greater throughput and coverage than its WIFI predecessors. The battle has just begun for wireless dominance…

There isn’t a profitable business segment today that isn’t competitive and that even includes the SPAMMING industry. Two of the biggest Spamming organizations, Nugache and Storm are currently going at each other head to head to dominate the SPAM/malware market. Yes, there is a market for SPAM and malware. Surprised? These organizations are not owned and operated by legitimate business people. No in is yet sure who is behind Storm but many IT security experts feel that Nugache is linked to the Russian Mob, aka the Russian Business Network.
Both of these organizations distribute SPAM through Zombie networks and both have been involved in highly criminal activities. Zombie networks are composed of PC’s across the globe, which have been compromised by some type of Trojan Horse which allows the Zombie controllers to then use them to send SPAM, conduct phishing attacks or other types of illegal activities. Each of these organizations control hundreds of thousands of computers. Take Storm for example. Some IT security experts have estimated that the Storm Zombie network, called the Storm Botnet, runs anywhere from one to fifty million computer systems. Even the most conservative estimates place the size somewhere around 150,000 to one million. The Storm Botnet in 2007 accounted for 8% of all malware on Microsoft Windows computers.
This year, Storm has an extremely viable competitor, Nugache. Although its zombie technology is not as sophisticated as Storm’s (for instance, Storm is somehow able to send SPAM in the native language of the receiver while Nugache cannot) Nugache has a big thing going for it right now, price. In an attempt to unseat Storm from its botnet dominance, Nugache has initiated a price war. Nugache will send one million emails for only $100. For $800 you can send 10 million emails.
It is because of the ridiculously meager amount of money that is required to SPAM a million people that SPAMMING is very profitable, even if the response rate to SPAM is only .01%. It is the sophistication of these controllable zombie networks that worry IT security professionals. Many fear that the current war for control of the malware market is only the beginning of this illegal destructive industry.
Johnny Lee is a brilliant technologist who’s become a YouTube star through his amazing demonstration of Wii remote hacks. After watching this video, you’ll never look at your Wii the same again. I love this video because Lee once again proves how integral human creativity and ingenuity are to the process of technological innovation. In this case, a relatively unknown guy like Lee on center stage at the famed TED conference, reinventing the very essence of what an already popular technology’s applications can ultimately be. These hacks are insane. Don’t miss this one…

A few days ago I purchased a new computer. The computer has a 4 gig hard drive — not much space for many programs. Well, I downloaded the updates or SP2 service pack the second day that I owned the computer. As we may see the hard drive is not built for that much data. Long story short; the hard drives capacity was reached.
Here is the solution: Re-install the software after a format and new partition. Well, the computer is small and has no CD drive. So, what to do? I thought that I could try to copy the software to a memory card and or an external hard drive and install from there. Guess what? The software was installed but the format was not in existence. The new installation files were copied right on top of the already full hard drive. Two other times the files were installed to the memory card and external hard drive.
After all this trouble the hard drive (c:/) did not register. Even better, the computer asked me what OS I wanted to load! I did make a selection but I had no luck. At that point I was without a functioning computer.
The problem: The programming or software on today’s memory cards and external hard drives are not always set to handle these installation problems. What we need is a solution to this problem. I have heard from other students that there is software for this situation, but it must not be an every day item. I have not seen much . . . to talk about.
Finally, I just paid for the external CD drive and I was back in business. Two things: 1. Attempting something new with available resources can lead to win, lose, or newly gained insight into a problematic situation. 2. Attempting something new can very much so be devistating to our equipment.
What did I gain, well; I understand that from a situation like this I can see what problems non-techs may have when they work with today’s computers. Although, I will be able to walk away from this task knowing that I can create software that is built for the common man or woman. I think it is a policy in today’s computer companies to think about the problems that can arise with software before it is sent out to the public. The main problem is the company that produced this computer did not realize that a 4 gig hard drive is not enough for today’s world. Solution: Do not allow the software to update, if it does the millions of customers out there will suffer the same fate that I did. Easy solutions for head-acking problemes!

Even in a poor economy, the IT job field remains hot. Despite the current economic woes, IT employment for the first quarter of 2008 shot up more than 12% compared with a year ago according to Information Week Magazine. The US added a total of 376,000 IT Jobs, making a total of 3.8 million people in the IT field.
This bodes well for future graduates of Ashworth University’s information technology programs because the biggest increase is in the computer support specialist field which grew by an astounding 41% in the past year, adding 127,000 jobs. Network and system administrator jobs grew by 31%, adding 51,000 jobs total. Despite the sustaining perception that the IT field has been weak ever since the IT bubble collapse and that all the jobs are going to India, the industry has added nearly 600,000 new jobs since its low point in 2002. In a digital and virtual world, the IT labor market is here to stay.
The 2008 Global Information Security Workforce Study was recently released. A total of 7,548 professionals in the field were surveyed. The complete study can be downloaded at https://www.isc2.org/cgi-bin/content.cgi?category=510
The most interesting headline from the study was the fact that 70 percent of all respondents reported that their own employees are the biggest threat to their organization’s security. This is contrary to the common belief that organizations must throw most of their resources at the outside perimeter of the organization’s network to prevent outsiders from accessing their network.
This premise is supported by a recent finding that email is now no longer the number one manner in which viruses access an organization’s network. With the ease at which employers now bring in thumb drives, personal laptops and PDA’s. Network security plans must focus on an umbrella approach that guards the entire network.
The threat of “cyber-terrorism” still strikes many as abstract, a symbolic fear first represented in seminal works such as William Gibson’s Neuromancer, followed by an explosion into pop-culture fantasy through the Wachowski Brothers’, “The Matrix.” While these dark visions of man’s accelerated move towards techno-slavery have certainly colored our perspectives, the reality of cyber-terrorism has existed since the 1950’s, when state secrets were first buried in dense programming language instead of manila folders labeled “top secret.”
Behind the curtain, the borderless battlefield is virtual and the threats are as imposing as those posed by nuclear weapons. After all, launch codes are just that—codes that are developed, stored, distributed, and controlled within cyberspace. The following podcast interview features Bruce Hoffman, a cyber-terrorism expert who outlines the precise nature and ominous implications posed by this threat. Mr. Hoffman also presents us with an in-depth report on how the U.S. government has redirected its’ counterterrorism strategies. Do you see a future where the Internet is under government control? Let’s think inside the box and brainstorm on the possibilities. Thanks.

The architecture of cyberspace is interconnected, timeless, and invisible from the inside-out. On the Ashworth University Blog, we’re not afraid of the matrix and try to share perspectives from around the world, just a 0 1 code, on the technology issues that influence how this network will evolve in complexity, and most of us would like that evolution to be open rather than closed in principle. Earlier this year, the nation of Estonia was involved in what by any measure must be considered one of the most large scale and sophisticated “cyber attacks” in history, an attack that operated on several levels simultaneously, resulting in the virtual collapse of this nation’s electronic infrastructure. Instantly, the fundamental question, “who did this?” was buzzing with elements of fear and conspiracy. Did Vladimir Putin and Russia conduct this operation in the shadow of political revenge? Was the attack the work of loosely connected and politically marginalized hackers who were sending their own message to an establishment attempting to exert increased state control over the Internet, i.e. you’re more vulnerable than you think and we’re waiting for your next move. The following video consists of an interview with information security expert, Dmitry Skylyarov, in which he shares his inside perspective on what occurred and the big picture implications of what is perhaps the most misunderstood yet powerful of political weapons; the large scale, well conceived, organized, and executed cyberattack. This is a must watch interview. Click on the image above to watch this video. We look forward to hearing your thoughts.
