1.  Improving Your Wireless Security

If you've read some of my other articles about having an open, unsecured wireless network versus securing your wireless network so that others can not get into it, you know that I believe in security.

I recommend that everyone secure their wireless network to the extent possible. It's impossible to completely secure a wireless system, but you can block out most users. You can make it difficult for others to use your network.

The point is to make the process hard enough that the visitor — the unauthorized person who is trying to use your network for normal Internet usage or illegal and/or immoral actions — decides to use someone else's network.

So, first, you never use "peer-to-peer" networking — always use the Infrastructure setting, which means that your computer will only connect to a router or access point. You don't want it to connect to someone else's computer directly!

You turn on encryption, set your encryption type to the maximum supported by the wireless equipment you're going to use, you set a unique SSID for your network, you turn off SSID Broadcasting, you use the MAC filter function of the router to limit the router to only communicating with your network devices.

There have been a number of changes in wireless security during the time that Windows XP has been available. Most of those were incorporated into XP Service Pack 2 or have been pushed down as "high priority" updates.

Unfortunately, Microsoft did not choose to push the update that adds WPA2 as a high-priority update. Perhaps they made that choice because older hardware wouldn't support WPA2. Perhaps they did it because the user would still have to change their network settings to use WPA2 — it could not be set to automatically install and be used. After all, you have to set the encryption type on your computer and you also have to set it on your router — otherwise, you just lose connectivity to the router!).

Regardless of the reason, if you knew that you wanted the increased security of WPA2, you needed a recent router, perhaps a firmware upgrade for it to add WPA2 capability, and you needed to download and install the Windows XP WPA2 patch from Microsoft.com.

By the way, if you install XP Service Pack 3, it will add this patch if its missing from your computer. If you aren't going to add SP3 yet, you can install the patch manually

2.  My Computer Security Software Recommendations

Anti-Virus

I'm often asked about several other popular anti-virus or anti-virus combination packages. Yes, I realize that they are not in my recommendation list. "Enough said..."

My personal choice is the ESET's small, fast NOD32 anti-virus program, which offers a FREE 30-day evaluation license. I consider NOD32 to be the cream of the crop in anti-virus protection. Unlike some of the others, ESET offers multiple-year licenses also, including updates to the program in the multiple-year license.

Many antivirus programs will offer you an anti-virus signature subscription renewal when your subscription renews. I strongly recommend against this option — buy the full program or make sure you get program updates with the subscription renewal (like NOD32 does). Vendors routinely improve the capabilities and speed of the programs, too.

If you update only the signatures, you miss any program improvements. Fortunately, NOD32's subscriptions include both program updates and signature updates.

Firewall Software

While the Windows XP firewall is much better than no firewall at all, don't count on the Windows XP firewall to meet your needs. You need a two-way firewall, which the Windows XP firewall is not!. Microsoft woke up and supplied a two-way firewall with Windows Vista.

The Windows XP firewall does not control outbound communications originating from your computer — and you should want to have control if adware/trojans/spyware or even commercial products want to talk to the Internet. Whether they are calling home or spewing spam, you want to be able to control your computer.

Do you want Windows Media Player to call home every time you play something? It does! Do you use the Search function in Windows Explorer to find things on your hard drive? Did you know that every time you search, Windows Explorer talks to Microsoft?

I didn't know that when I ran ZoneAlarm, but the Sunbelt Personal Firewall flags that to me, and I can stop it or allow it to happen. Many other programs try to call home when you run them, too.

I recommend my choice for a firewall program, which is Sunbelt Personal Firewall.

You can try the full-featured "paid version" of Sunbelt Personal Firewall free for 30 days — after that, you can register it or, if you're using it on a home non-business computer, you can let it revert to the free, lesser-function license.

Sunbelt Personal Firewall is regularly $19.95 (with discounts for multiple computers and/or multiple years!) for a non-expiring license for the program and includes one year of their updates subscription.

Anti-Spyware / Anti-Adware Software

CounterSpy, from Sunbelt Software, has received many kudos from the computer press for its always-running and periodic full system scans. It is also my personal choice for my PC's and my family's PC's.

Sunbelt released their CounterSpy v2 in February 2007 and I promptly updated my computers to it. Version 2 greatly improved CounterSpy's performance and reduced its load on the computer when it was scanning.

In July, 2007, Sunbelt released v2.5 of CounterSpy, which again both improved CounterSpy's performance against malware and reduced its impact on system resources and responsiveness when its scanning.

Sunbelt continues to release updated program versions. Nicely, they do NOT install the updated programs automatically. You have to use the Update process in the program, which means that you'll know that something significant has changed!

Anti-spam Software

In today's Internet world, the question is not "if" you will get spam, but "how much will you get?"

I use and now I recommend POPFile as my first choice for handling spam. POPFile sits on your computer, between your email program and your ISP mailbox, and handles emial as it downloads.

POPFile uses a different approach to handle spam than some other programs do — it does nothing to reduce spam. It is designed as an email classification tool — you train it to recognize spam and any other type of email that you want to classify. These classifications can help you sort your emails into appropriate folders in your email program.

Sunbelt Software, who makes the anti-spyware program CounterSpy (which I use and recommend) and the firewall that I use and recommend (Sunbelt Personal Firewall) also has a well-regarded, award-winning anti-spam program called iHateSpam for Outlook and Outlook Express. Since I don't use Outlook or Outlook Express for email, I haven't tried iHateSpam.

Mailwasher Pro is my first choice to handle spam before it ever gets into your computer's Inbox. Mailwasher Pro uses on-line Realtime Black Lists mail servers sending spam recently, "training" by you of what you think is spam, and your own "friends" and "blacklist" lists.

Mailwasher Pro can even bounce spam messages, as if your email address was not valid, although the usefulness and appropriateness of this is questionable. There is a free version called "Mailwasher," but it omits the functions that I consider critical for this purpose -- such as safely previewing the emails safely before they ever get to your email inbox.

Cable/DSL Router

If you have a cable modem or a DSL modem, you need to have another layer of inexpensive protection between you and the Internet. A cable/DSL router isolates your computer from direct connection to the Internet. Your computer can easily request your email, web pages, etc. through the router. The responses come back to the router and are smoothly routed to your computer. But, someone on the Internet side of the router can not initiate a connection to your computer — they can only respond to your request.

Even if you only have one computer to connect to your cable or DSL modem, I recommend that you purchase and use a cable/DSL router because of the protection it can give you against attempts to attack through some flaws in Windows itself.

A router isolates your local network, whether it is only one computer or several, from the Internet by actually making it a separate network. The router gets the "public" IP address and handles all your outbound communications and the responses to them. But, it blocks computers on the Internet side from being able to initiate communications with your computer! This will prevent you from falling prey to many worms that try to attack security holes in Windows itself.

For a wireless router, I recommend the Linksys WRT54G wireless router. I'm using the relatively new version 6 of this router.

If you don't want wireless, I recommend the Linksys BEFSR41 wired router. Either way, based on my experience, I recommend Linksys routers for price, reliability and Linksys' habit of releasing updated firmware for their products..
