And how can one into the System by booting from a CD if it still
requires the Password even in Single User mode?
Booting from CD, floppy or hard disk is slected at BIOS level.
Booting in single or multi user mode is at Operating system level.
Booting is in the following order:
1) BIOS select what medium to boot from
2) the operating system boot from the selected medium
So when it comes to the Single user password, itis already at stage 2)
it has passed the stage 1 (booting from hard disk ofr CD) without
password.

So, it means, that I should take the following steps
1. Password on BIOS
2. Change the order of booting i.e. When system is installed and working
once, then I just the change the Booting FIRST from HardDisk.
3. Put the password on Single User mode.
So, what more? Do you people think that I have got somehow security
for unauthorized access?
Physically _LOCK_ the server up. Anyone who can get physical access to
the
unit can remove the drive and access it from another machine, bypassing
all
this stuff.
Another option is to encrypt the hard drives, but this will require you
(or
someone else) to enter the password for the encrypted drives every time
the
system boots up, so it's generally a maintenance nightmare.
Well, I am not an expert on FreeBSD. And thats why I don't know that how it
works that
If 4 Disks of same size for example 146GB each and they are configured with
RAID 10, and Root, SWAP, /usr, /var File systems have been created on them.
And if one takes one or two harddisks and how come he would be able to read
the data when data is splited on 4 disks?
Your logic escapes me. If someone were to physically break in to the machine
to steal your data, why would they only take some of the drives?
