author=1forhope link=board=computer_security;num=1077560829;start=0#2 date=02/26/04 at 16:21:15]What is a CMOS password? How do I establish this? Also, how does one acquire a "Firewall"? Where do you get "Zone Alarm", off the net or in the stores?
I am certainly not a security expert, but...... well..........
LOCAL "SECURITY:"
This doesn't really work........ but if you really want to......
A CMOS (complementary metal oxide semiconductor, at least that's what it stands for, but in this context it refers to what is stored there) password, also probably more correctly called a BIOS (basic input/output system) password, is something set to prevent changes to the settings that control the basic hardware operation of your system, such as allowing the computer to be started from a floppy disk or CD-ROM. To minimize local (note local meaning someone actually is physically present at your computer) security risk, look in the manual that hopefully came in your computer for the secret keypress, which you need to enter when you first turn power to your computer and see the manufacturer logo.................. most common would be one of the F? keys........ try F1 first.....
Once in, look for something called "boot order," and set the hard drive first. Then look for "power-on password," which will require a password to start the computer, and a CMOS password, which will prevent changes to what you have just done. Not all BIOSes support these features.
Now buy a padlock, and lock the case shut.
Note someone determined enough, could, of course, break the lock, tear of the case, reset the CMOS jumper, change the boot order, and boot from an evil floppy........... but this is (a little) better than nothing.
Now for the weakest link...... set a windows password.
INTERNET:
A firewall is a piece of software and hardware that sits between you and the internet. Simply put, it lets the things you want in and out, and drops everything else. You can get a firewall in a software store, or from the web. Personally, (because I don't use windows), I use iptables, which (i think) is part of the linux kernel itself, and I configure it through GuardDog, because I haven't really learned how to configure it directly. But I digress....
It would appear Zone Alarm is here:

That said, there is a limit to your security, especially if someone really wants your information in particular.
