A Guide To A Well Protected System

10 Answers To Technical Questions For Our Grandchildren

February 24, 2008 Posted by James Oliver

This is kinda Jeopardy Style

1. It was a device that at one time had a cord plugged into it like a tail with a roller underneath it. You would move it around on your desk to move your “cursor” around on your “monitor”. Then you’d press buttons on it to execute commands on your computer.

2. It was something plugged into your computer that would display the output from the computer. It was in 2D. They were bulky, but got lighter when the “flat panels” were created. Holographics was only in the movies at the time.

3. It was a device that we would use our fingers to press buttons that allowed alpha-numeric characters to print on a “monitor”. There were also classes you could take to improve your efficiency using this device.

4. Well, back then, no one really cared about trees. They would chop them up into little pieces and press them together and create something called “paper” (just like at the museums). This device would output onto the sheets of “paper” with “ink”. School children even used paper to write out their schoolwork on using archaic devices called “pens”

5. Well, it was the part of a computer that held all the components. It was the size of a transporter engine. At one time, it would take up as much room as a domicile. Apple was the first to engineer something much smaller for their computer systems.

6. For entertainment, people would sit for hours and play these. There were a variety of these. Some as simple as a yellow circle with a mouth eating dots! Some could be played via the internet with people all over the world. You would control a graphic on the “monitor” to do a variety of tasks in a somewhat 3d world!

7. People actually payed for a service that would transfer your voice to someone else. Everyone had their own identification number which when entered, would sound a noise at the other end signaling the other person to activate on their end. The early versions used small wire, and then improved to a now obsolete fiber optic cable.

8. People would use small devices to conduct business and for entertainment. Before the government assigned “Personal Wireless Activity Units” which monitor your Internet activity, people could do almost anything and remain anonymous without government intervention. This was when a computer could be called a “Personal Computer”

9. It was a software application installed on a persons Personal Computer that detected and removed “viruses” which could destroy data, steal information, and render computers useless. There were people with expertise in this arena who actually were paid monetary units to install and use these software packages. This was until Kaspersky led the way to abolishing viruses for good.

10. It was a huge company that dominated the archaic operating systems. It was expensive, and it was costing people millions of dollars in “Identity Theft” and software. The flaws in their operating system eventually led to programming groups banding together to create an operating system called “Linux” which led to what we use now.

Surge Protection / UPS

 Posted by James Oliver

One thing often overlooked when setting up a system is the Surge Protection or UPS.

A UPS offers some protection against surges, but it’s still a good idea to plug the surge protector into the wall and the UPS into the surge protector. Worse case, you’re saving the surge protector a few surges.

A UPS offers a battery backup system. When setup properly, it will gracefully shut down your computer system after a pre-determined time period. This prevents your system from just turning off like it was unplugged during power failure. In order to get the best results from a UPS, you should plug in limited equipment into it. Perhaps only the PC and the Monitor. This way, the UPS will give you time to shut

When a computer just loses power (power failure, coming unplugged, etc) it’s hard on many of the components of the system. It can cause power supply failure over time, motherboard issues, hard drive problems, data loss, and more. It’s a great idea to spend a few bucks at your local electronics retailer or online for a good UPS.

Lightning Storms

In all honesty, the best thing to do if you are near the computers and you know a lightning storm is approaching, is to unplug the power, and any powered devices from your computer. This includes phone lines, network cables and printers. If you have ensured there is no power to any of these devices, they could remain plugged into the PC.

If lightning sends a surge into your home through phone lines, and your DSL modem is plugged into the phone line, it could fry the modem, send the surge on to your network switch/router and then to your computer. It’s important to protect your equipment. The only fool proof way is to make sure everything is unplugged from every source of power.

Make FireFox Lightning Fast!

February 12, 2008 Posted by James Oliver

The following will be helpful to broadband users:

Step 1. Type “about:config” into the address bar and hit return.

Scroll down and look for the following entries (it’s in alphabetical order):

  • network.http.pipelining
  • network.http.proxy.pipelining
  • network.http.pipelining.maxrequests

Step 2. Alter the entries as follows:

  • Set “network.http.pipelining” to “true” (by dbl-clicking)
  • Set “network.http.proxy.pipelining” to “true” (by dbl-clicking)
  • Set “network.http.pipelining.maxrequests” to some number like 30. (This enables it to make 30 requests at once.)

Step 3. Lastly right-click anywhere in the whitespace and select New-> Integer. Name it “nglayout.initialpaint.delay” and set its value to “0. (This value is the amount of time the browser waits before it acts on information it recieves.)

By default, FireFox will make one request to a web page at a time. When you enable pipelining, it will make several requests at once giving it a major performance boost.

You should see a MUCH faster response from FireFox now!

Don’t Let Your Bank Account Be Exploited!

February 9, 2008 Posted by James Oliver

In the early part of 2007, a friend of mine was one of the speakers at the MySQL convention in Las Vegas (I believe). While attending, he was able to listen to speakers from companies like Google, Yahoo, etc.

One of the things he learned and brought back to me was an exploit using javascript that allows a website owner to check through visited links (history), for websites. This can be useful for seeing if they’ve been to competition, and then you could even redirect them to a page that compares against the competition.

However, a more sinister and likely use to a less than ethical webmaster might be to check for banking institutions (Chase, Bank of America, PayPal, etc.) to see which you visit. Once they have this information, they’ll know which site to target you for.

This script could be loaded into a 1px X 1px iframe within a page and never even noticed by the end-user.

What can you do to protect yourself?

Use separate browsers. You can use one for your regular surfing/business, but use another browser for your banking. Dedicate a browser for your banking. There are tons of choices out there. Opera, FireFox, Eudora, Flock, etc. The browsing history does not cross browsers, so the “attacker” would not be able to find your browsing history. This is the best and most solid solution.

If you are a dedicated FireFox user, you can add the SafeHistory Extension (https://addons.mozilla.org/en-US/fi…x/addon/1502) and this will be helpful if you only want to use this browser.

There are no extentions like this for Internet Explorer because they don’t really care about security because they’re Microsoft and no one would ever exploit their browser :)
