I wouldn't recommend using both, as it can cause various conflicts.
Go with a reputable hardware firewall and make sure the Firmware is up-to-date. Keep in mind that while a software firewall will ask the user on each and every attempt, this can be overbearing and often annoying.
Software firewalls tend to be a lot more intimidating to users due to the pop ups that ask what you'd like to do. Hardware firewalls do the quietest behind the scenes blocking....combining the two can be a bit of overkill but in this world....is it really overkill?
Though there was probably more to the story, such as missing patches, perhaps, is immaterial.

My preference for HW firewalls is SonicWall. They sport a high level of configurability yet work suitably out of the box.
The more complexity you add to a given PC, the more chance there is for problems. The SW firewalls that keep popping up to ask if a certain thing should be allowed through only confuses many users, which leads to frustration and an unhappy customer. They can also be quite resource and bandwidth hungry. Just a few years ago you couldn't touch a HW firewall with stateful packet inspection (SPI) for less than $500. Now, even the cheapest Linksys routers tout SPI. In short, HW firewalls are transparent and they work.

First of all, I have used Windows OSs since Windows 2.0. My computer has been online all the time for the last 4 years, at least. I NEVER turn it off. I have NEVER had a virus nor had my credit card and/or banking information stolen or misued nor has any other security breach occurred. I teach my customers how to protect themselves and rarely do any of them have a problem once they become my customers.
Secondly, even if someone buys into this illogical argument, i.e. if everyone should switch to Mac or Linux, it would only be a brief matter of time until hackers and crackers started attacking those OSs as well.
Most advice in the article is very sound, while some of it may seem a little bit excessive. Avoiding mainstream software can and will reduce your chances of being vulnerable to any given exploit. Anyway, the best way to stay secure is to know, exactly, what you are doing with your computer. Altough most people would be reluctant on entering a swimming pool full of gasoline while smoking a cigarette (I would be reluctant to stand less than a hundred feet away from such a pool, with or without a cigarette), the very same people will happily open any small program that claims to be funny on their Windows boxes.
While using my Windows box, I put myself within the reach of any scrip-kid or clueless spammer. While I am on my MIPS/BSD or PPC/Linux boxes, I am comfortably above their reach with very little added effort.
I come from ths first computer store that ever was 32 years ago. We used CP/M in the spring of 1974 and the only security in "NOT BEING CONNECTED TO ANYTHING." Not a phone, cable or dsl. Keep everyone out of your office. Don't let anyone touch your computer ever. Then only your software will get you.
Never put any data that you "Can't" afford to lose or you want someone to know on a computer.
There, that clears that up. Now do what you want and suffer the consiquenses because that is what you will do anyway.
Run XP-SP-2 and all the New Viruses will get you.
The last one I had shut off my Symantec Virus Program, tried to trash my Linux server, execpt it shut down rather than be crupted. I spent 140 hours building a "NEW" hard drive, the old one was cycled until the "Head" was snaped off. Part of tne new Multitasking Viruses now out there.
Every day i learn something new, so should you.

Of course, one could look at the traffic fatality rates for the nation and see that it really makes a difference, but if you are more concerned with your personal experience, then knock yourself out.
Now I know what his logic is - most people ARE incapable of creating and remembering secure passwords, and most people only loose their wallet a few times in a life time (hopefully). But you know, when that wallet is stolen and the thief gets your password and a bunch of credit cards he's going to be all over those banking websites quicker than you can say "Rob me blind!". Also people will not be able to guard that written down password - they'll be pulling out their piece of paper and leaving it around and dropping it letting friends see it inadvertantly.
Plus, it presupposes that people will actually uses a longer, safer password just because they wrote it down - now they'll continue to use lame-o-passwords like their dogs name and still get their logins compromise.
I agree with the SPIRIT of Bruce's suggestion here, but practically I don't think its a very good one.
How about "call your bank and demand they three level authentication with password, physical key and biometric confirmation". Banks save a ton of money when their customers use on-line banking, so consumers should also be demanding that they supply the necessary hardware free.
Don't do it!!! You want to have a real problem?
Now a thief has your credit cards, password, home address for home invation and stealing your computer, a list of your valuables on your computer along with pictures, lockbox information and on and on and on. Take large gun, ****, shoot foot several times, don't call 911 watch your foot bleed. Makes as much sense?? You want security? Get one of those memory chips you wear around your neck that works with USB 2.0. Use an encription program and a USB cable or you may have a front port on your system. Just plug the memory in and it will ask you several random questiones only you would know. Each time you log in, it asks different questions. It's thats best way until "Brain Scans" come along.

The way to get around that is to NEVER use the same username and password at more than one secure site. If you want to remember them, then use a good password manager that encrypts them and has its own master password that's hard to guess. And back it up.
But you may need to have some of your passwords with you. If you make them good enough that they give you some security, you will not be likely to remember them.
So here's how to write them down: Don't make it obvious. For example, if I have a card in my wallet listing my bank account number, the bank's 800 number, and my PIN, a thief might try my PIN. But if he does, the ATM may swallow up my card and never give it back. My REAL PIN might be digits 2-6 of the phone number, or a part of the supposed account number that only I know. For a password, I might have an easy way of altering the username or password or both to make it less obvious. I might have the first two entries with phony names, and the real password is really two lines down on the list. Or I might stick three random letters in front of each password, or two behind each one. Or I might come up with a simple algorithm that will give me a number between 1 and 4 for each line to figure out how many random characters to use. Or I might write them backwards with fake leading characters. Or I might write them backwards with an extra random character after position four. Or I might not write the username down at all, if I can remember them. Or if I make a habit of starting all of my usernames with "BOBBY" and ending them with a number, I can write down only the number, and the password encoded with one of the above rules. All of these are examples of ones I don't actually do, but are simple enough that if somebody found your list, it would be useless. Use your imagination.
Instead, I use an encrypted password keeper program running on a different machine. That machine requires a seperate password to log on and a different password to access the password keeper program. I only access the program if I cannot remember a password. Works great as far as I am concerned.
Don't take this portion of his advice, or if you do, make *sure* you know what you are doing, and can restore those files if necessary.
Mr. Schneier is exaggerating the lengths to which a person need go. However, these tactics would work! Realistically, the only safe computer is one that is never plugged in. But we aren't talking about extremes. We are talking about the types of steps that *can* be applied. Take all the steps that you can afford to prevent system infiltration/infection/corruption.
With regard to seat belts (and other such passive approaches to safety), you need only one accident that propels you through the windshield or one infection that steals your credit card nuber to realize the necessity of such devices.
You guys can nitpick to your hearts' content, but if you stop looking for one single answer and find the safest method(s) that work for you, you will be much better off.
One more thing that you can do to make your computer safer is to (and this only applies to those who want to take the time) back up all data and reload your OS and all necessary updates once or twice a year depending upon how many people use a particular computer. Not only does this help with security, it also helps with a slowing system due to junk file buildup.
In fact the opposite is true.
Relying on your bank to shred all their printouts is far more risky than having non-complex passwords for your bank accounts and credit cards.
Also the advantage of online banking is you can see, usually to the minute, what transactions are taking place (except checks, which you usually have until 2pm local time the following day to get the bank to return them manually).
So not using online banking does two things. It leaves a possible paper trail (statements, debit and credit receipts) for people to steal if they haven't been cross shredded, and it prevents you from being able to easily keep track of transactions.
Add to this, most credit cards and banks offer zero liability against fraudulant transactions (good banks will re-deposit the disputed cash in 24 hours, then reserve the right to take it back up to a month later if they find out the transaction was valid), and you are far better off using online financing.
The problem was that as soon as he handed his check to a teller, she just typed it into a computer anyway. Since the check does not have the account number of the depositor on it, it has to be done manually, and there's room for error.
That doesn't count the fact that the check run might be delayed and he would not get his check anyway, or it might fall out of his pocket on the way to the bank, or his briefcase might get stolen, or he might get hit by a car.
The down side is that he used to buy snacks for us when he went to the bank, and we lost those once he finally changed his mind and signed up for direct deposit. Oh, well.
Basically you are saying the author is wrong because of your own personal experience. I direct you to this article ( hxxp://en.wikipedia.org/wiki/Hasty_generalization ) on the logical fallacy of hasty generalization / biased sample.
If you didn't have 16,000 programmers attempting to exploit a hole in an OS (every second of the day) there would not be a problem (see Mac). If you're OS was fresh off the ground, chances are you're not going to have many problems (see Linux); but be patient because I gauruntee we'll be walking this same rope in the future with Linux.
Keep in mind that the majority of people who are experiencing these problems are your older generation (and other unsavvy users) who have taken advantage of High Speed Broadband with little or no computer/networking/security education.
In my 5 years of "Always On" connections I've obtained a single virus (curteousy P2P networks); have lost no capital through Online Purchases and have not become a victim of other "Online Traps".
While Cryptography is a great security advancement, perhaps it does not relate to the day to day operations of keeping workstations clean and secure.
I'll take advice from my Auto Mechanic when it comes to my car; I'll take advice from my baker when they say this bread is fresh, but I won't take advice from you on keeping my systems clean and secure.
I respect the President of the United States to all ends of the planet, but I'm not going to let him tell me how to secure my network.
Backing up is the best thing since sliced bread, it should be a no brainer. If it's not, make it a no brainer! You can be your best friend, or your own worst enemy.
Encrypting email is a quality standard if you're regularly in communication with other tech savvy people who understand the processes of encrypting mail (who use the same encryption programs), however most novice users are clueless if they recieve an encrypted email.
Utilize your anti-virus program to your advantage. Take the time to figure it out; read the manual; get automatic updates running; if you're unsure, scan it! Spyware...Ad-aware/Spybot/ if those fail, Hi-Jack-This (if you're a newby please seek help online with this one, you can wreck an OS).
Be extremely warry of emails as this is a hitting point for spoofing, phishing, scripts, .jpgs and attatchments.
I have to disagree with the passwords....make em tough for yourself to remember. If I can memorize a 26 digit wep key, a 8-12 character password can't be too difficult! Personally I yield away from on-line banking (but again I only started using banks recently, thanks real job!); and have told my users of my decision, and why I've made that decision. Follow if you'd like, go your own route if you'd rather!
Please, whatever you do, leave the cmd.exe alone as this is one of the best programs within XP!
2) Brush twice a day
3) Always swim with a buddy
4) Dont have any fun on your computer
5) Be afraid constantly, and only boot computer if you have to. Then ask yourself again.
6) Never use computer
someone has previously mentioned, just because one person
hasn't had any problems, it doesn't mean all people will have no
problems and we can't always point fingers at those that simply
are not coputer savvy.
I also believe the reasoning behind there being more Windows
holes and security problems is because the majority use
Windows and therefore has, according to Bri Lo "16,000
programmers attempting to exploit a hole in an OS (every
second of the day)" doesn't wash. Are you trying to tell me that
NO-ONE ever tries and creates a virus or security hack for Mac
OS X? Wouldn't that be the ultimate claim to fame? In an area
which is all about outdoing one another, surely the ultimate
virus would be one that spreads via 'bullet proof' OS X?
Perhaps the reason there are no Viruses for the Apple operating
system is simply because no one has ever managed to create
one that circumvents it without the users knowledge. I'm not
saying there never will be anythig for any other OS, including the
Mac but well, it simply doesn't make sense to not try and write
one for it.
"I respect the President of the United States to all ends of the
planet, but I'm not going to let him tell me how to secure my
network". You lost all respect with that comment with a man that
sends a nation to war based on lies - if you respect your
President as much as you respect your OS, you have my
sympathy!
I used Mozilla and it worked just fine and I was able to save the article as a file as well.

are a windows user you do not have to stop using windows...
1) Do not enable ActiveX controls in your web browser. Make the setting disabled or prompt which is now default.
2) If you MUST use a laptop then setup an internal firewall on the laptop
3) Use www.blockallspam.com email services for anti-spam. Your anti-virus will not have to be as "lucky".
Anti-virus systems are more often than not FAR behind the viruses that are out on the net.
They are a false sense of security. Get fewer spams, download programs only when absolutely necessary.
4) Use EUDORA. It does not have security problems that can be exploited. You do not have to turn off HTML.
5) Monitor your equipment keep an eye out for Hard disk and network utilization.
6) And Yes, install and use an anti-virus system. It is better to have something than nothing if you download files.
Always remember, there is "NO" real security!!
If your information is too valuable for other people to see, "Don't Put it on a Computer"!!!

I so loathe stupid debit card myths. (BTW Yes I do work for a bank)
So your Risk is that you might not be able to charge things. (and you might convince the bank to up your credit limit during the dispute).
Now lets throw the same fraud on your debit card:
The money is taken from your checking accout:
Ooops... a bunch of checks you wrote just bounced!
Now you have a passle of return check charges,
Nasty dunning letters,
Notifications from credit card companies that the bad check triggers the 'default provision' and your new interest rate is 25%...
And your car insurance has been canceled, and notification has been sent to the Motor Vehicles Dept.
----
But don't worry, the Bank will but your money back just as soon as the fraud investigation is completed.
----
Sure hope that happens before they repo your car and foreclose your mortgage.
---
I don't use my debit card on the net simply because my paycheck direct deposits into that account. Were someone to illegally access my account they can drain my entire paycheck (on a good day for them) and I've got to go through the hassle of dealing with that problem. With a true credit card they may get my whold credit limit, but it is (in my case) typically smaller than my paycheck and so much easier for me to lose access to for a few days.
2) Yeah, right. Like all the home users out there are going to reformat their Windows computer to Linux, abandoning the vast amounts of software that they've paid for.
3) He's wrong - it's easy to create a secure password in two easy steps:
a) think of a word of medium length that has an 'o' in it (like 'football')
b) use that word, but make the first letter capital and replace the 'o' with zeros (so it would be 'F00tball'). That wasn't so hard was it?
4) My password solution above is a LOT more secure than the ridiculous statement of keeping passwords written down and stored in a wallet.
5) It's strange how this guy appears to be a Linux fan who doesn't like Microsoft, but actually uses the "windows update" feature to trust Microsoft to install whatever junk it wants onto your home machine. Use hfnetchk from download.com to keep up with Windows security updates. Really - a CTO who uses Windows Update. That's disgusting.
6) Destroy your old backups by putting them in your microwave??!?! Is this guy still in grade school or something? Do not destroy backups of your software by microwaving them. It'll make your home smell like melted plastic with fumes that are hazardous, and may cause damage to your microwave. Just get out your car keys and scratch up the surface. Then trash it. Use your microwave for food.
7) It's really unneccesary to encrypt your email (for home users). That's overkill. Instead, just make it your policy not to send financial or password information through email.
- - - - -
This guy is "... one of the world's foremost security experts."?!?!? What a silly boast. The world is a very big place, and this guy doesn't even come close to that title.
The fact that he is the CTO of an Internet Security company is astounding, considering how completely senseless his suggestions are. If correct steps are taken, a home user can operate a Windows home PC very, very securely. Obviously, this buffoon has no idea how to properly secure a Windows OS. He also doesn't seem to care, being that he's a Linux fan. Rather than appeal to the vast majority of home computer users (a market dominated by Windows), he instead tells them to abandon the operating system and software that they have.
Could someone please pick this guy's pocket so we can get all his passwords and hack him? (Digging through his trash would probably work, too).
What a complete imbecile.
Obviously anyone who thinks "f00tball" is a secure password needs to shut up and pay attention the next time his company does Security Awareness Training!
Back-ups of files, great.
Careful that you are on a valid website, great.
On the other hand this is my entire arsenal.
Windows XP Service Pack 2 + Updates
Latest Updated Norton Antivirus
Router with a Firewall (Windows Firewall is off)
Spybot Search and Destroy with resident monitoring
Weekly Ad-Aware 6 Scan
Only Norton and Spybot are running resident.
That's about all the overhead I'm willing to
give up for security's sake.
I have even gone back primarily to IE6 instead of Firefox. It is much better now with XP Service Pack 2. I still like a few of the features I can get with Firefox and when I want them, I call it up. The "find on this page" function is great, it lets you keep your eyes on the copy of the web page during long searches. I also like the developer extension while I'm testing a web page.
Delete cmd and command.com? I don't trust any GUI interface that much, especially Windows, with good reason. Consider the filename:
test.txt.html
You could look at it forever in Windows Explorer and never see that it has two file extensions.
"What is wrong with this file"? you keep muttering to yourself.
I could go on, but I think it would require more medication.
So now I find comfort in the fact that I'm not the most cynical computer user in the world anymore, someone way more "in the dark place" has supplanted me.

I will admit that I did catch a worm once (because there was no warning out there, even for months afterward, that clicking a link could cause problems). But ZoneAlarm caught the outgoing program which I shut down immediately and within an hour I had the worm cleaned up.
I do occassionally run one of the free internet a/v checkers but there is never anything there.
cases---like deleting cmd.exe!) still won't protect you from
shady websites or stores. I consider myself a computer security
expert but still have been ripped off by online merchants. I
would add an anti-fraud/anti-phishing product like EarthLink
