Is it really possible to "Quarantine" three system hard drives from a
single hard drive when that hard drive is used for internet related
purposes?(The idea is to keep them from from viruses, hacking, ect.).

Thanks a lot.

There was a retail product called "Hard Drive Sherrif" that might help you.

I always thought a nice product would be a big red switch and a
modification of defrag. You decide, with some assistance from the
software, which files you don't want changed, probably forever.
The software moves all those to one side of "the fence." Things
that you are expecting to change are kept on the other side of "the
fence." When it is finished moving files it asks you to flip the
switch. Then any attempt to write on the wrong side of the fence
results in a disk write error and it doesn't do the write. No
software can then flip that switch, and that is the essential part
of providing that security. (It actually wouldn't be too difficult
for a company to build such a product)

It would seem to me that a substantial fraction of your hard drive
is stuff that you likely very very rarely want to change, and if
something does try to change that then it is almost certainly a
bug or a virus. (Now if Microsoft just didn't need to patch their
code every week we would be set!)

I believe in the past I have seen hard drives with a jumper that write
protects a hard drive (SCSI drives ?)
Maybe you could go into the bios at startup and disable the IDE controller
the drives are connected to.
Or put the drives into an external USB case and leave the drive disconnected
when not in use.

I'll be using Windows XP. All four drives will be in a single case.
And I really need to be able to access any of the drives on a dime,
but will be spending most of the time using drive "C".

Basically, what I'm looking for is something simular in principle to
the way the "Recycle Bin" works. Data/apps in there cannot be changed.
One would have to restore them first.

Since those "brains" over at Microsoft will never come up with a
secure OS, you'd think that a simple "Quarantine" function would be
incorporated into their products.

Thanks a lot.

I have not personally done what you are trying to do. That said
simply typed in
" password protect hard drive " on Google and got a ton of hits.
This one looks promising...... http://www.softstack.com/hidedrv.html

Hide and Protect Drives will apparently password protect hard drives,
floppy drives...... even CD and DVD drives. ( BTW....It's $29.95 )

Let us know if you find something better. Good luck!

Such a "quarantine" function would be no more reliable than the security of
the OS. While you can't call up a file from the recycle bin and edit it
with Word someone who knows what he's about should be able to alter the
contents regardless--those files aren't really protected in any special
manner.

If you're running 2K/XP I believe you can set policies on the drives that
deny writing to specific users--I know you can do that if you have a domain
going just don't recall if it's possible to do it with workstation working
standalone. That's fairly robust.

_Safest_ bet is to put the files you want to protect on a server that has no
Internet access and then use the security features of the OS on that server
to prevent writing. That way security is handled independently of anything
that happens on your working machine. You can use Linux or BSD on the
server if you can't afford Windows Server or if you feel like doing a
little "sweet talking" you can probably get a 5 user copy of Netware for
Small Business (or whatever they're calling it this week) out of your local
Novell authorized reseller--the 5 user is officially free but available
only through resellers.

Format the drives as NTFS, set the security permissions "Read" for everybody
and "modify" for Administrators.
Then, to copy files there, you'll need to be logged as an administrator. Any
account will be able to read those files.

To make sure the malware won't be able to install on your computer: never
work as an administrator or a member of Administrators group. Make your user
account "limited user". Then, even some security hole or your own fault will
allow some malware install to run, it won't be able to copy anything to the
system folders and register itself in the OS.

I just need a *simple* way to protect 3 out of 4 drives when not in
use, and save to them quickly when I have to. So having to create Zip
drives or getting a server to store my files is not an option. And
paying $30 for an unproven app(wiht very little comments about it on
the net) that *might* protect my drives from hacking and viruses
doesn't seem plausible. And I don't know how it is possible to get 3
out of four drives to recognize me as an "Administrator" with the one
single drive allowing full access.

I guess a firewall should be my first line of defense, but shouldn't I
be able to set up a SCSI system to spin down 3 out of 4 drives until I
access them?

(I guess if there was an easy way to do this, it would be widely
know).

Thanks.

You don't. He's telling you how do operate the machine so ALL 'drives' are
as protected as they can be. You should not normally be logged on as an
administrator so that any malicious code you run across then has full
administrator rights to run through the system at will.

Then you can change write rights on the 'protected' drives, or anything
else you want 'protected', so that nothing but an administrator has write
rights and since you will not be logged on as administrator no malicious
code can use your rights to alter them.

You may not want to hear this, but it's a trivial task in Linux.

Via Samba, you can integrate that with Windows.

How quick is quickly? How about USB2/Firewire enclosures - and pull the
plug to protect??

Why is a server not an option? speed?

Under Linux just umount them :)

Gee, that is how the more than 260+ FREE, Open Source, Operating
Systems, and, MAC OSX, all work, NOW! The /ROOT system can ONLY be
changed by the Sys.Admin.! (Unlike XP, which can be cracked, via a
floppy, usb drive, or, through remote access!).

Here ar 190+ LiveCDs to play with!

Uhuh, and when exactly did you inform this group that your drives are SCSI?

It is, but for you to accept anything and not moan about it, that is the problem.
Or maybe your uncanny ability to misunderstand what you read.

But since as I said, I'll be working with my "C" drive(and will only
occasionally need to copy to the other three), it seems that I won't
have the freemdom I need with that drive until I login in as an
"Administrator", which of course opens up the other drives to
malicious code.

It seems that you're talking about an all-or-nothing solution, and I
need complete freedom with *one* drive while protecting the others. Or
is there sommething I'm not being told?

Basically, I'd need for the "C" drive to "see" me as an
"Administrator", but not the other three drives. IS that possible?

Nevertheless, the system doesn't exist yet. I want to build two with
one of them being SCSI. I haven't decided if the one to be connected
to the internet is to be that one.

What's your point?

I understand that you are a troll looking for someone to harass. Find
someone else to start with. There are a lot of other threads.

And what does 'working with' the C drive mean?

Your 'plan' opens them to malicious code by leaving your C: drive
completely unprotected, so that it can become infected, and then it infects
the other drives the instant you 'spin them up'.

You're asking for 'complete freedom', why I don't know, for the drive on
which an infection is most likely since every targeted vulnerability
resides on it, and the one where it matter most, yet want to be
'protected'. Just ain't going to happen.

Yes. Format them NTFS and then mount/dismount them when needed. Or buy
'removable' drives and 'unplug' them when not needed. Doesn't really matter
because whatever vulnerability you're protecting them from will simply
infect them the moment you activate them.

So, asking a question here, what would it take in terms of hardware
between the IDE cable and the drive to make a (non-boot) drive
read-only? Or maybe non-existant? Back in the old ST506/MFM days
I imagine that a switch to disconnect the write signal to the drive
would have done it. The same might be possible with (non-boot) IDE
drives.

And you might be able to accomplish the same with SCSI drives.

Then you don't need any suspicious software to pay for, you don't
need another operating system to use, any attempt to write to the
drive would likely just get an error reported by your OS, and on
the rare occasions you want to write to the drive you close the
switch.

I'm going to give you a rather extreme suggestion that is quite workable and
about as secure as you're going to get with a single machine, but not
particularly simple or cheap. Run your Windows under VirtualPC for OS/2
with Netware 4.1 for OS/2, accessing your additional drives via Netware.
All runs on one box, quite reliable, performance is acceptable on modern
hardware, primary Internet exposure is OS/2 which if not bulletproof (and
OS/2 fans, I didn't say it wasn't bulletproof, just that even if it isn't)
is at least uncommon enough to be below the radar for crackers, you have
Novell's very robust and fine-grained security, you can do your
administration from a separate Windows session that is set up under IPX/SPX
and has no Internet access, so you can turn on and off privilege for your
working session as required, and your working Windows session is isolated
in the VirtualPC sandbox.

Less extreme, you could run your Windows session under VMWare on a Linux
box, with your additional drives accessed via SAMBA. Security is not as
fine-grained as Netware but should be plenty for what you want to do, you
can enable write access when desired from the Linux console without closing
Windows or unplugging anything, again Windows is isolated in a
virtual-machine sandbox, and primary internet exposure is Linux, which
while not below the radar doesn't have a whole heck of a lot of known
exploits extant.

Could also do this with VMware or VirtualPC under Windows, running
"dangerous" activities in the virtual session--this would be more secure
than running it in your console session but Windows would be exposed on the
Net, and there are known exploits that require only exposure. Again you'd
enable or disable write access from the console session.

That you're trying to reinvent the wheel to a certain extent,
that having protected data is the whole purpose behind removable
media and/or disconnected backup storage?

The moment you are in a position to access those other drive(s),
so is any virus/etc. If it were simply a matter of "denial" of
access to drives, would viri exist at all? Could we not simply
assign all file transfers to a ramdrive and deny all traditional
physical storage rights?

WinXP should be able to pick up a drive connected to a SCSI IDE
controller if it is powered on, from being off, while system
stays running, providing your SCSI controller also supports this.
In other words, you'd be closing power circuit to drive to use
it, then opening circuit again when done. If you can settle for
manually flipping a switch, it is relatively easy, or you could
go a more complicated route and have software commands to cause a
port to drive a relay to do it.

But I'm talking about the option of keeping all my data in one
place(case) and protecting it.

I'm not trying to reinvent the wheel. The wheel is inherently faulty.

There is no great technological hurdle in hardware manufacturers
making systems that give the user total control over the writing
between drives(without having to power them down), but they will not
do it.

Perhaps in the future one will have the option of "flipping a switch"
to quarantine specific drives, keeping them from being written to.

As I recall, to read an IDE drive you have to write to its registers.

I believe that is true, something like 8 registers make up IDE. You
fill some of those with the block number on the drive and then fill
a command register with a read command. But I've never found any
info on someone trying to protect drives with this, or do other
silly things like display the current block number on the front of
the case, the way some wierd off-brand pc did fifteen years ago.

thanks
