Sins of The Internet: Mousetraps (and worse)

Written by Richard Lowe


Continued from page 1

Sorepparttar point is to get as much traffic torepparttar 118974 site as fast as possible, which is whyrepparttar 118975 page from a proven high-traffic site is stolen. It already works and no development is needed. Oncerepparttar 118976 traffic arrives, as many banners, links and other advertisements must be shown as quickly as possible (but not so quickly as to crashrepparttar 118977 system or prevent them from being viewed or clicked). This gives your poor trapped visitors plenty of opportunity to see banners, click on them or even possible buy something (you never know).

Ah, but wait, it can get even worse. Up until this pointrepparttar 118978 site has been playing withrepparttar 118979 browser, which has some reasonable security (usually) and must follow a set of rules. But what ifrepparttar 118980 site tries to download an ActiveX control or an executable file? Yes,repparttar 118981 browser will ask you if it's okay (unless you've had a serious case ofrepparttar 118982 stupids and turned off ALL security) and only install or run it if you say yes.

But if you do say yes, then you've potentially added, willingly I might add becauserepparttar 118983 browser did ask for permission, a totally unknown element to your system. There is absolutely no telling what this could do. In fact, it might do anything at all.

This program does not usually destroy anything. No, what it wants to do is dial up a phone number - a 900-type number. You know, one of those phone lines which charges byrepparttar 118984 minute.

Now you are really in trouble and you will not even know it until you get your phone bill. Something on your computer, something over which you have no control, can do anything it wants, including charging you money on your phone bill. And heaven help you if you, in some moment of insanity, give this program your credit card number or numbers. (And, of course, it could theoretically scan your hard drive for such things).

So what do you do to protect yourself from mousetraps or worse? Number one, set reasonable security. What I like to do is define repparttar 118985 internet as high security (this is done usingrepparttar 118986 "security" tab of "Internet Options"). This prevents javascript and other dangers from running at all. When I find a site which I trust which requires these features, I add it torepparttar 118987 trusted sites list. Thus, it's not possible (baring a browser bug) for a site to even begin to cause me trouble.

If you don't want to go through those lengths, you can examinerepparttar 118988 security tab and set things to "prompt" instead of "enable". Be especially sure all ActiveX controls at least prompt (never, ever allow ActiveX controls to install themselves without at least your permission).

If you do go to a site which traps you, don't panic. Close windows, trying not to click on any links or banners (why give them any more money) as quickly as you can. Then make a mental not to never, ever come back. You might also shoot an email off torepparttar 118989 webmaster and perhaps some of their advertisers protesting their use of these tactics. This way you make your feelings known and perhaps produce a change.

DNS

Continued from page 1

Nowrepparttar system has no choice except to look outside torepparttar 118973 internet to try and translaterepparttar 118974 URL. So your system will send a translation request out to your primary DNS server. This is usually supplied to you by your ISP when you installed your computer onrepparttar 118975 internet. Ifrepparttar 118976 primary DNS server cannot be reached for some reason, thenrepparttar 118977 secondary DNS server will be queried.

Okay, now it gets a little more complicated so we will work with an example. Assumerepparttar 118978 address "www.internet-tips.net". A name server may or may not (depending upon what type of name server and how it is configured) remember addresses that have been requested before. If they remember, then they will simply returnrepparttar 118979 translation directly back to your computer.

Most likely, though,repparttar 118980 primary DNS does not know how to translaterepparttar 118981 hostname, so it will go out and ask some other name servers. It will start withrepparttar 118982 root domain (.NET in our example) and ask it if it knows how to translate "internet-tips". The .NET name server may or may not know. So it will either say "sure, here'srepparttar 118983 address" or "no, I don't know, but here arerepparttar 118984 addresses of some other name servers in .NET that may know." These servers will be asked, and will performrepparttar 118985 same actions. This will continue until there is no where to turn forrepparttar 118986 answer (there is no resolution) orrepparttar 118987 translation is found.

Oncerepparttar 118988 name server who knowsrepparttar 118989 address of "internet-tips" is found, it will be asked if it knowsrepparttar 118990 address ofrepparttar 118991 "www". It will either returnrepparttar 118992 address (this is very likely) or returnrepparttar 118993 name(s) of name servers that might knowrepparttar 118994 answer themselves.

Now thatrepparttar 118995 name server (primary or secondary) asrepparttar 118996 actual TCP/IP address it sends it back to your machine.

I hope that helps explain, just a little, howrepparttar 118997 magic really works underrepparttar 118998 covers.
