Network Security guide for the home or small business network – intermission…

Sunday, January 1st, 2006

At this point I’ve exhausted all the topics on network and computer security that I was eager to cover. As things change/ ideas strike I may well add to this series. One direction I see it going is talking in detail about several network utilities and more advanced topics like looking into web site ownership, [...]

Network Security guide for the home or small business network – Part 20 heterogeneous networks

Sunday, January 1st, 2006

One thing I’ve already mentioned in this serious is using alternative programs like Mozilla Firefox instead of Internet Explorer, or Thunderbird, Eduora instead of Outlook Express. Even if you’re not using alternative software as your primary web browser, email program there are advantages to having networks with mixed software, operating systems and even mixed network [...]

Network Security guide for the home or small business network – Part 19 – What about when you’re not on your home network?

Saturday, December 31st, 2005

When you’re not at your home network is probably one of those times you should be more on your guard. Wireless access points are very common and a greatly useful thing, but there are some steps you should take to protect yourself, your pc and the data stored there. First it’s worth having a personal [...]

Network Security guide for the home or small business network – Part 18 – What about Dialup Users?

Friday, December 30th, 2005

So, most everything so far has been targetted to high speed internet users or business networks. That means if I use dialup I’m safe. Wrong. For starters, in many ways dialup internet is LESS of a risk than high speed broadband for two main reasons. First, high speed/broadband connections are typically on ALL the time. [...]

Network Security guide for the home or small business network – Part 17 – The Security Mindset

Thursday, December 29th, 2005

This may be one of the most important entries in this series. An important defence against those that would try to access your network is to constantly have the “security mindset”. Ask yourself “do I need this, how could it be exploited, what are the implications of this”… When it comes to people asking you [...]

Network Security guide for the home or small business network – Part 16 – Learn about the enemy

Wednesday, December 28th, 2005

I remember I had a geography teacher once that was a former Marine and he said when he was growing up it was the height of the cold war and geography was interesting to him from a “know your enemy” point of view. That’s a good concept to apply to computer security and network security. [...]

Network Security guide for the home or small business network – Part 15 – Security Through obscurity

Tuesday, December 27th, 2005

I remember many years ago watching a Dr. Who episode where a very important key was “hidden” in a display of many other keys. Kind of like hiding a tree in a forest. This concept is “security by obscurity”. Generally this is considered a bad approach to security. It is a bad approach if this [...]

Network Security guide for the home or small business network – Part 14 – Alternative software

Monday, December 26th, 2005

There are ways that risks can be avoided. Recently, there was what was called a zero-day exploit for Internet Explorer. As I write this, the exploit surfaced 3 weeks ago and tomorrow there will be a patch. The vulnerability would allow remote code execution through a vulnerability in the way javascript is handled. So, for [...]

Network Security guide for the home or small business network – Part 13 – Your own worst enemy

Sunday, December 25th, 2005

Once upon a time I did an article about the biggest computer security vulnerability ever. I’ve also passed along the old “the most dangerous part of a car is the nut behind the wheel” joke. If you haven’t got it yet, the computer user can be the “weakest link”. Let’s face it, you’ve got antivirus, [...]

Network Security guide for the home or small business network – Part 12 – Antispyware

Saturday, December 24th, 2005

I’ve talked about Antivirus software as an essential. Today we’re going to look at Antispyware software. There is a difference. By definition a virus is a piece of software that infects other files or copies itself. A worm is a virus that spreads without user intervention. (From one open network port to another for instance.)
