Thanks to Education Portal and some research of my own, I am able to present a small list of free technology courses. eLearning is the wave of the future, what better way is there to experience it for yourself than for free? All you need is a little bit of time and a descent internet connection to learn about the following:

• Computer Networking at MIT
• Principles of Computing Systems
• Computer Graphics
• Internet Technology
• Operating Systems
• Beginning Web Design
• Linux 101
• Email Basics

If you are interested in a more in-depth technology learning program, I highly recommend Western Governors University. Western Governors University is a non-profit online university. When I was looking up rates for various eLearning options, WGU had by far the most affordable programs available. On top of that, they are heavily accredited and well respect by employers.

There are also several other free online learning opportunities outside of technology, consider the following:

Goodwill Community Foundation

HP

Education Portal

Small Business Administration

With the rapid expansion of online learning over the past five years, and the computer literacy of children today, it would not at all surprise me to see most successful colleges and universities embracing online learning for most of their instruction within fifteen years. As that happens, we should hope to see more free programs available to the general public and to those who otherwise could not afford to benefit from them.

There is a new computer exploit in the wild, one that allows hackers and criminal elements to inject code of their choosing into popular internet websites. Once this code has been injected to the unsuspecting website, and you visit it, your computer will become infected with additional code that allows the hackers to then gain control over your computer. What’s worse, you will probably never know that your computer is infected without the help of a computer security expert. Just by visiting websites on the internet you’re at risk. Once infected, your computer will be used by the hackers to remotely send spam, steal private data, purchase goods on stolen credits and perform other types of online crime. All of this will happen invisible to you, in the background, using your internet connection. When the authorities go to trace back the source of the crimes that have been perpetrated, they will see your IP address and mistake you as the criminal, because the crimes originated from your ISP, even though you had nothing to do with them!

There are basically two problems at work here. First, there is a problem with vulnerable Microsoft IIS web servers, along with Microsoft SQL and Active Server Pages (ASP). The problem is described pretty well over at Dancho Danchev’s blog. This is a SQL injection attack and it works on servers with website code that is poorly written and does not validate input passed via ASP forms to SQL server. There’s a pretty impressive (but partial) list of websites that are infected via this Google Link. Basically, the majority of websites in this list (and many, many more that aren’t listed) will cause your computer to become infected upon browsing to them. I do not recommend you browse to or visit any of the websites listed unless you are using the Firefox browser and have the noscript add-on installed. See my earlier post that links to and describes browsing the internet safely with noscript and Firefox.

Website owners beware. If any pages on your website have a script that looks something like this, you’re infected: “script src=http://www.nihaorr1.com/1.js” If you currently own or manage a website and are concerned about the possibility of your website being infected, contact Leo Polus today. We offer professional website services and can check your server for problems, cleaning up any vulnerabilities if found.

The second problem exists on the computers of individual internet users. It deals with the alarming rate at which Javascript is expanding into every website on the internet. You can hardly use a modern website on the internet without Javascript being enabled, and this presents a real challenge for Noscript. Noscript works when you use it sparingly, turning it on only for the most trusted of sites that you visit. Now, with the exploit taking over legitimate websites, even those sites that you think you can trust and enable scripting for could in fact contain malicious code that will damage your computer. Noscript is no longer a reliable security tool under these circumstances. In fact, noscript could actually be harmful, giving you a false sense of security on websites that you’ve always been able to trust but have since been exploited.

The best defense against this existing threat is the use of Windows Hosts files. I won’t go into the details of using Windows Hosts, there is already a lot of really good information on the internet that can tell you how to configure them. Personally, I’ve added both 127.0.0.1 nihaorr1 .com and haoliuliang.net to Windows Hosts and now I can feel a little bit safer. Exploits that take advantage of scripts on these websites will instead harmlessly bounce back to my local machine. There are plenty of other exploit websites you can find to add to a Windows Hosts file just by searching on Google.

If you are concerned about the security of your computer or your personal data, please contact a computer security professional at Leo Polus immediately to have your computer scanned, cleaned and protected.

PayPal has released a white paper via their blog which suggests that future visitors to PayPal may receive a message asking them to upgrade their browser in order to continue using the PayPal service. Specifically, “unsafe” browsers which include versions of Internet Explorer prior to version 7, earlier versions of FireFox, Safari Web Browsers and any other browser that does not support the latest security methods will be denied access to the PayPal website. PayPal hopes that, by preventing access to visitors using older version browsers, it can convince the visitors to upgrade to more secure browser versions. This will protect both the browser user (from online security threats) and PayPal, through reduced account access and account losses as a result of phishing.

It’s about time! Hopefully this act by PayPal will be the trickle that forms a stream that forms a river for online security. Currently, only a small percentage of computer users understand the dangers of browsing the internet. Most do not know that your computer can be infected with a trojan, passwords can be stolen and your privacy violated simply by visiting an unsafe web page. These attacks often happen in the background, hidden to the user and the victim will never even know that they’ve been infected. Often times, the end result of this is a need for a computer professional to visit and perform spyware and virus cleanup to fix the infected computer. By informing users who visit their website that their browser is not safe, PayPal is providing an excellent service to the internet that will result in a safer experience online for everyone. It could also save the average consumer billions of dollars in PC security related charges.

This solution has been suggested before, preventing visitors from accessing a website if they are using older or unsupported browsers. The problem is that you can’t, from a business perspective, exclude potential visitors from your website. Doing so will only frustrate them and convince them to go elsewhere for business, to a competitors website that does not ban their browser. However, a large company like PayPal is mostly immune to this problem. They already have a firm grasp on the online market for payment of goods and services, and enough companies use PayPal to process transactions that users will be more likely to follow their instructions than turn away. We need more large companies like PayPal to enforce these types of standards before the little guys like us can follow suit. Eventually, however, if this plan by PayPal works out, secure browsing on the internet will become the norm.

Some tips for internet surfers everywhere that can be implemented immediately:

• Ensure that you have the latest version of your browser by checking for updates on a regular basis.
• Ensure that you have all patches installed for your operating system by checking for updates on a regular basis.
• As a general rule, Mozilla Firefox is a more secure browser than Internet Explorer and it should be used as your primary web browser.
• While using Firefox, you should also use the NoScript plug-in to further enhance security.
• Employ a software and hardware firewall at all times.

The United States Postal Service (USPS) has instituted a new pilot program whereby they will take small electronics, cellular phones and inkjet cartridges, for free, and recycle them. This is pretty cool! Previously it was always a hassle to find somewhere to recycle these small electronic devices and, in most cases, it was easier to just throw them in the trash than to call all over town to find a facility willing to take them. The great thing about the new USPS program is the simplicity of it. All you have to do is put the device into an envelope (provided by the post office for free) and then drop it into the mail.

An example of the types of products you can recycle through this method: Inkjet cartridges, PDAs, Cell Phones, Digital Cameras, iPods, MP3 Players.

Since the components are recycled and reused, they don’t end up in landfills and this actually helps the environment. You can find the envelopes for free in any Post Office and you can take as many as you’d like. Be sure to keep some on hand for ease of use the next time you need to dispose of a broken technology item.

The pilot is set for 10 areas across the country, including Washington, D.C., Chicago, Los Angeles and San Diego, but could become a national program this fall if the pilot program proves successful.
