Steven Noonan sends us to a page where he is collecting and updating results for various browsers on the newly released Acid 3 test. No browser yet scores 100 on this test. (We discussed Acid 3 when it came out.) He writes, “It’s not surprising that Internet Explorer is losing to every other modern browser, but how did IE 5.5 beat IE 6.0 and 7.0?” All of the IE versions score below 20 on Acid 3.Read more of this story at Slashdot.

If you spend a lot of time on the internet and you are not behind a firewall, then you are living on borrowed time. Putting some protection between you and the internet is probably the third most important thing that you can do (after getting virus checking software and performing regular backups).
The diagram to the left shows an unprotected system using a DSL modem. As you can see, someone on the internet can attack the computer system easily as the DSL modem provides no protection (some DSL modems have built-in firewalls). An attacker can get through any type of modem - DSL, cable, 56K, 28.8 or whatever. If the device gets you on the internet, you are vulnerable.

Social Engineering is the attempt to gain access to sensitive data (such as password, usernames and credit card numbers) by gaining trust. This method of gaining access to a system is very popular among hackers. It is often surprisingly easy and even more often successful. THIS IS PROBABLY THE MOST SUCCESSFUL AND MOST USED METHOD OF GAINING ENTRY TO ACCOUNTS!
Here’s how it works. You might receive a phone call from a representative of your computer company claiming there is a problem which requires immediate attention. He may offer to come right over and fix it (or, n a variation, he might send you a disk in the mail). Of course, while he is there, he reboots your system with a “diagnostic” floppy inserted into the drive. When the “tests” are done you will be relieved to find out from him that nothing is wrong with your system. Naturally, you were just infected with a Trojan house which gives this stranger complete access to your system and all of your data files.
