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. Which raises your exposure. Like the security through obscurity concept though… just because dialup is only online a limited amount of time, that shouldn’t be the only reliance on protecting your system.

Network Security guide for the home or small business network – Part 17 – The Security Mindset
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 to click on a link… “do I trust the person, am I sure it’s from the person that it claims to be… how sure? is it normal behavior for this person to ask me to click on a link?” I guess what it comes down to is developing some healthy critical thinking and skepticism…

One other note from the previous series on WMF exploit infestation cleanup. Among the multiple popups that came when launching internet explorer, most were directed at the site http://60.topnssearch.com –

A Tip for cleaning up an infected PC
There’s a joke that many people bring out when new Windows viruses hit big…. it goes along the lines of, “download a fix here” and the link points to a knoppix linux livecd download, or a Mandriva download disk, fedora/etc… Some say linux isn’t affected by as many viruses because it lacks market share, I would point out that server market share (take a look at how many linux web servers there are…) would seem to tip the scales a bit, but that’s not the point of this post. What is the point is this…. When you have a Windows pc that is infested what you should do is disconnect from the internet. The problem is, that typically prevents you from getting the tools you need to fix the machine.

Network Security guide for the home or small business network – Part 13 – Your own worst enemy
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, a firewall, all the current windows updates, antispyware and a website pops up. The website looks like Windows security center and says you have a virus and need to get official antivirus software.

Network Security guide for the home or small business network – Part 11 – Why?
Alright, so you’re still reading this series and you’re thinking. Look, I’m not protecting national security secrets. All I’m doing is (running a business|emailing my grandkids|using the web for research).
True, good point. You’re not at the defense department. OK. Let’s say you just use your computer for email and web browsing. That’s low priority stuff right? No sensitive information on your PC? Do you ever do banking online? Yes – then you should be concerned… No? You should still be concerned… here’s why…

Disinfecting a PC… part 10
Before I get things wrapped up, I like to scan rinse and repeat until the scans come up clean. So, this scan of AVG gives a chance to delete the archive entry I mentioned the first pass it took. And spybot get’s updated from the internet and re-runs. All looks clean there… Ad-aware get’s an update check and runs again. Everything there looks clean now. The next thing to do is disable and uninstall tightvnc, I don’t want to leave bhodemon running at boot or the tea-timer from spybot now that things are fairly settled.

Network Security guide for the home or small business network – Part 7 – Wireless Networking
OK – the last couple of entries got into some heavy lifting and some real learning on your part. Learning about what software needs to run, what services are running, updating them to keep current on security patches. We even talked about securing services listening for outside connections and limiting them to what is absolutely necessary. Now we’ll take a deep breath and get into another area… Wireless network security.

Disinfecting a PC… part 5
OK, we’re moving on to BHOdemon to take care of the browser helper objects. Unfortunately it looks like BHODemon is not being currently maintained, the developer has had a housefire.
I am very sorry, but BHODemon is currently on hiatus, as I no longer have the time to devote to it (due to a house fire). You will not be able to download updates or upload reports, and I will no longer be answering emails. At some point, BHODemon may return. I would like to thank everyone for their support over the years.

Network Security guide for the home or small business network – Part 2 – A Software Firewall
Do I really need a hardware firewall? I’m running XP Service Pack 2 with the built in firewall? (or norton, or zonealarm?) Well, personal firewalls (the name that software firewalls go by) are good for a great many things that hardware firewalls AREN’T. They do have their limitations though and I’ll try to cover those in this post. Of course, a software firewall is running on the pc that you use to connect to the internet and one of the functions it serves is to “close the doors and windows” or those open ports that a computer can listen for connections on.
