No matter how many security systems you have in place, you should always
stick with these 5 rules for Internet safety:
1. Always use good passwords.
Choose gibberish words that are not
from the dictionary and use uppercase and lowercase letters, punctuation, and
numbers. The more random the password, the more difficult it is to crack.
2. Don't turn on services unnecessarily.
File sharing is the No. 1
problem. If you don't have a reason to use file sharing, turn it off. Don't run
an FTP or a Web server unless you have a reason. These services open ports and
make your computer accessible. If you have to use these services, then refer to
rule No. 1.
3. Be stealthy and don't name your computer something
obvious.
Don't put your name or anything associated with you on the
computer. Otherwise, if people sniff you (this is very easy to do) and find out
your name, they have more reason to attack. Don't put your name or address in
your computer.
4. When you're on the Internet, hide your IP address.
If you're
using an ICQ, make sure you use the security feature and turn off your IP
address. You can use a program such as Freedom from Zero Knowledge to hide your
IP address from all comers.
5. As long as you're connected with broadband, you're at some
risk.
Using a firewall greatly reduces your risk, but if you're not
actively using the Internet and you're still concerned, unplug your Net
connection.
