I guess the security also could be a good topic,  good anti-virus and anti-spyware freeware you already mentioned.  How to hide IP address from public viewing to protect the potiential attack? I saw there is freeware that is offerring this kind of features, but am not sure if it is useful.  For the people that have kids, any way could prevent the kids from viewing some specific sites?
...



I am long over due on this question. It is a HUGE topic, of which, not many people can claim expert. I'm no exception.

However, I'll share my personal views on the matter. I encourage all readers chip in your tips on good (bad L) security practice, so we may all benefit.

Home network security is almost like your real home security. Every family practices their home security at a level that they feel comfortable with. Besides a few what I consider must-to-do’s, it really boils down to “common sense”.

Obviously, for most of us, security becomes an issue only when we get online. What do I we get online for?

Let’s see: 1. emails (send/receive), 2. Surf sites (view, download) 3. Share data (happen with kids more often) 4. Real time communication (chat).

Some activities are definitely more dangerous than others. However, email stands out the most common cause of security breaches (via virus). So, for family users, extra caution should be given to email security (more tips below). Next, you should be careful about downloading programs. Kids have even more to worry about with music sharing, online chat etc.

I have a few highly recommended practices. I also try to tag each item with one or more categories, such as (general, email etc).

1. (general purpose, emails) Keep antivirus up-to-date:

I already recommended
http://free.grisoft.com/ free edition. Antivirus is the most basic defense line against (email) security breach. The importance can not be overstated. So do yourself a favor, keep it up-to-date.

2. (general purpose) Keep system patch up-to-update:

From your IE browser, “Tools/Windows Update”), I recommend use express update, let windows take charge. While you are doing this, Windows also asks you if you want to do automatic system update. I recommend “yes”. No home security is good if all your doors or windows have holes in them. That’s where the attack commonly come from. This may be even more important than item 1.


3. (common sense) Choose “Never save password” when browser prompts you to save password for you. I personally don’t want computer to remember my password. Anyone gets on my computer can just login into my accounts. I am surprised nobody has sued the software vendor for providing this feature, given that somebody would even sue $65M for a stinky pair of pants! I believe the system should never offer to save. If a user wants to do so, he/she can click the options, and do it knowingly.

4. (email) If you get too many junk mails, I recommend you try to access your email online using the browser, instead of using your Outlook (express) client on your local computer. So the junks are not automatically downloaded to your computer before you even get chance to delete them. Or at least, get online to clean it up periodically before using your Outlook to view the emails. Also, if you are unsure about a piece of email, you still want to open it, I would use browser to open it than to use the Outlook client (It makes me feel a bit more safe this way, although this could be simply an urban myth. J)

5.
(common sense) Never click on those “You won $1 million bucks!” popup! Better yet, install google tool bar, which has a popup blocker, it’s very effective.
http://toolbar.google.com/T4/index_pack.html

6. (common sense) If you are done with your online financial transaction (banking, credit card purchase etc), close the browser (or even all open browsers) to clean up the buffer, so nobody can sit at your desk and get into your account.

7. (common sense) Choose a strong password for your online financial accounts (I recommend a mixed case, at least one upper case, at least one number, at least one special letter), don’t overlook this simple matter. It’s VERY important. Just like you have good lock on your home door. I know there are folks out there who don’t even lock their doors at night. Well, didn’t I say it’s “common sense”? Everybody has his/her own practice, but we definitely know some are good and some are what I call bad security practice!

8. (advanced) install firewall, you can use http://www.zonealarm.com, click on trial version, it has a basic version for free.

9. (general) install anti-spyware, I don’t have a particular one to recommend. Anyone has a good recommendation?

10. (Parental control): I know Cox cable offers a free package to its customers. https://phoenix.cox.net/cci/internettoolspopupblocker It contains antivirus, parent control and some additional features. I used it before, it is kind of really slow, you can set the parent control level, but it can become a nuisance when it blocks too many sites. So I don’t have a good one to recommend. Anyone has a good recommendation?

11. (common sense) Installing programs: make sure you know what site you are visiting, you understand what the program is for, and you REALLY want it before you start to download and install programs. If you feel uncomfortable after install, go to “add/remove programs” to uninstall it as early as you can, so it won’t create additional junks on your computer, which uninstall normally don’t clean up for you.

12. (special) Kids online share software: my answer is no. I’m sorry I can’t come up with a better answer. If that answer may potentially cause a run-away teenager, I would back off in two steps: a) let her/him install it for a short while (a few hours while she/he is dying to download some silly thing), then uninstall right after. b) she/he may use it to download, but never put anything to share. c) never allow the program to run automatically when your computer fires up. Manually control start/stop the “silly” shareware.

13. (parental control) Never allow your kids to chat with any strangers online! Period. No exception. Generally, watch over their shoulder from time to time to make sure you know whom they are chatting with. You should allow her/him to access internet in an public area in your home that you can easily walk up and see what she/he is doing.

Oh, don’t forget about the basic wireless security practice I talked about in http://nawomen.com/viewthread.php?tid=12421.

Finally, onto your question about hide your IP address: It would be good if there is a simple solution. The software that hides your public IP uses some kind of convoluted solution. I personally don’t feel comfortable with the additional complexity which is out of my control. Also remember, only your public IP is viewable. Your private IP is shielded automatically by your router. Although it’s not the perfect solution, it’s better than nothing. That’s just my 2 cents.

Now, I would like to hear what others have to share what’s your good security practice or some piece of good security software you want to recommend?

同意,避免将电脑安置在他们的卧式。From day one, we set up computer in the family room and let them get used to do it in fixed area.  When the laptop and home wireless are getting more and more popular, I am wondering if we still can do this a couple years later.

Yes, Sir. 俺就再告诉一声: Is it just me or what? I still can't see “我的文集” in the drop menu of "我的”. I can't see anybody else's 文集 either.

I see. I actually never tried to access it that way. But that's a good point. I may add a link for that later. But for now, I think the new version of forum calls that "我的空间", from there you can explore more than just 文集. Each member should be able to personalize her own "我的空间". Click on the "帮助" on the menu to see more info.

You can also get to any member's "个人空间" by simply clicking on the member's name on each post (in the area right above the avatar). I think this link is for your personal space http://nawomen.com/space.php?uid=5194

选择"我的空间", 可看见包括文集等更多的内容. 点击"帮助" (http://nawomen.com/faq.php), 应该能看见有关的信息.

Please don't hesitate to ask questions. I am not an expert user of this forum at all. But you never know, somebody out there may know the answer. There are too many features, I have no idea what they are for and how to "play" with them.

我想这坛子里应该会有高手. 不仅是个人空间, 如知道怎样使用高级功能, 希望能与大家共享.

Thank a lot, Superdog.

I'll try later. I actually have noticed the change from My Collection to My Space. I kind of like the old one better. However, I'm not totally against learning about the new feature. I'll report about my browsing experience later. You are doing the heck of a good job here.

You've already answered this question once.

Thanks, Superdog. I looked at it again. It's not there the old way, but it's there as "个人空间". I'm okay with it. I'm getting used to "个人空间"。Thanks again for following it up.

My daughter hasn't bumped into one YET!

I'm sure I'll benefit from your answer to this question, Superdog. 俺给她来个有备无患。
