[qubes-users] HCL - Dell Latitude E6430

2017-08-30 Thread Santiago R.R.
Hi,

I was forgetting to send the HCL for my Dell Latitude. I have been using
Qubes 3.2 since last March, and everything works great so far. I still
need to test the cdrom drive and bluetooth though.

Thanks for this splendid OS,

Santiago

[qubes-users] HCL - custom build with GIGABYTE Z270N-WIFI and Core i5-7600k

2017-08-30 Thread Daniel Sage
Hello!



I have not done too much testing, but I have found some issues/things of note:



Qubes doesn't even boot to the LUKS password screen unless I have VT-d disabled

This is resolved by removing "iommu=no-igfx" from "/boot/efi/EFI/qubes/xen.cfg" 
and re-enabling VT-d

qubesd would not start after the initial boot until I updated to 
"qubes-dom0-current-testing"

The video keeps flickering/stuttering occasionally while using Firefox in the 
personal domain

This may occur at other times, but I have not noticed it yet

The "current-testing" updates did install an updated kernel but I think I need 
to manually activate it to see if that resolves this issue

Wifi works flawlessly on the 2.4 GHz band

I have not tested 5.0 GHz



Unrelated to Qubes, the BIOS reports it supports a TPM but there is no header 
on the motherboard to actually install one.

[qubes-users] strange dual display mouse issue

2017-08-30 Thread pixel fairy
qubes is always "quirky" :)

this time, i was having trouble with a monitor that was randomly blanking for 
2-3 seconds at a time, so now im using a tv to see if the issue is that 
monitor. 

with the second monitor, when using gnome-terminal on a fedora-25 appvm, on the 
laptop, the mouse scrollwheel doesnt work. when the terminal is dragged up to 
the tv, the wheel works. on a debian-9 appvm, the wheel works in either 
terminal.

dont remember having this issue with the real monitor.

The question as always is, what are you protecting? If it's your user data,

that's a lost cause, as the vm sudo page explains. If it's some kind of malware 
that could get written with root privileges, well, that gets erased by 
rebooting the VM, unless it's persistent in your user data, but if it is, it's 
incredibly unlikely to be runable (at least not without explicit user action).

I raise these questions because the answer to many of the "OMGWTFBBQ passwordless sudo" threads 
that appear every so often, come back down to either "whatever you're proposing wouldn't make a 
difference read the doc again" and "are you sure you read the doc and understood why the decision 
was made the way it was?"


I believe the direction of the recurring discussion has been following a 
somewhat different arc. Joanna and Marek have lately been receptive 
(even supportive) to internal domU security... at least ways to enable 
it. I think the impetus for the shift boils down to these points:


1. VMs shouldn't passively amass malware, even if its not a threat to 
Xen isolation; its a nuisance at best that can affect other 
computers/devices. DispVMs help in prevention, but not for many normal 
PC usage scenarios.


2. DomU OS's have unobtrusive security features ready for use with 
little or no burden to us:


With 'vmsudo' auth prompts configured, using basic domU security is very 
easy: Say yes/no to the prompt shown in dom0. This is not about 
passwords in AppVMs.


3. Such domU defenses, while judged to be inferior in general, do 
receive patches and could allow Qubes systems to thwart attacks 
ultimately aimed at the hypervisor. This matters even if Linux, etc. 
remains "swiss cheese" and saves our bacon in only a small percentage of 
scenarios.


4. Qubes' read-only templates provide a basis for anti-threat 
persistence measures like 'Qubes-VM-hardening'[1], but only if domU auth 
is enabled.


5. Xen security was not quite as good as was hoped.


Guest OS's supposedly compete on the basis of security, so its probably 
best to let them do their job in this regard. Especially if all that 
requires from us is to not switch off security or a little bit of PAM 
configuration.



this wasnt specifically because of the passwordless sudo. its a general access 
control and hardening thing. i see firejail as complementary to qubes-os. ssh 
shouldnt access the x server. firefox shouldnt write outside of its own folder 
and Downloads. neither should shell out and call sudo. when they do, or try to, 
id really like to know about it. firejail can log such access, and you can have 
another process follow that log to alert you.

but having firejail do that, and watching that log, are more processes, more 
attack surface.

to add to extremely unlikely, ive only known of one ssh client exploit in the 
wild, and i think it was over 10 years ago.


FWIW, AppArmor does work with Qubes VMs and doesn't revolve around a 
special launcher.

The tool you would need for doing this is "msed" (name given in my
fedora distro) or "sedutil" (from the drive trust alliance) which allows
you to talk to the drive via sata (not usb afaik) to encrypt or protect
defined ranges that you set up.

Just be careful to learn/test on a test system, because if you create an
encrypted range everything previously there disappears instantly,
including partitions. Its the world fastest way I know to completely
wipe a drive, flip one bit in the key, poof. Like magic. You can always
reset back to the factory default erasing everything on the drive.

Calculate your ranges, partition, setup encryption ranges, and install
stuff, then finally mark your /boot range as read-only. Don't encrypt
your /boot or you will need to install Pre-Boot-Authentication (PBA) and
supply a password at boot time.

Sedutil source and docs

This is interesting. I suppose this would be a way to secure your system, and 
then you could add AEM over it? That way you are using the security features of 
the hardware, but not trusting them.



As far as "trusting" the drive, you first need a TPM for this to even 
work, so not all the apples are in one basket. The key itself is not 
stored anywhere on the drive, but only a partial entropy seed value 
which when combined with the users password the drive can then generate 
the required key on the fly.


If used for encrypting your data, all that work is done within the drive 
hardware thus freeing up your host cpu for other things. If you are the 
paranoid belt and suspenders kind you can also encrypt your data before 
it goes to the drive where it gets encrypted yet again automatically. 
Layers of security are always better.


It is possible to have the drive bound and unlocked by a specific 
TPM/PCR value generated during a trusted boot process. That way not only 
is your drive not writable by the adversary, but the drive itself must 
be physically in that specific machine/TPM otherwise it remains as 
useful to the adversary as a paperweight. In the context of xkcd, even 
beating you over the head for a password won't help if its not in a 
correctly booted known state of that specific machine/TPM combination.

http://imgs.xkcd.com/comics/security.png

For the ultra-ultra-ultra paranoid you can even have a hidden partition 
table such that it exposes the real drive partitioning only after the 
drive is unlocked (aka. the 'done bit is set' to expose the shadow MBR). 
This way you can boot readonly into a stripped down ISO image OS with 
AEM/trusted boot to check for any extra devices connected, then use the 
PCR magic hash to finally unlock and expose the real partition table, 
and then boot again into the actual R/W OS partition. That's the 
use-case that I'm working on for a pet project of mine.


I would think that Whonix devs might like to play with that kind of 
scenario for providing absolute "plausible deniability" when that 
subsystem is not in use. When you don't need it, you could not even tell 
that the partition exists, just unallocated sectors on the drive with 
(encrypted) garbage bytes in it.


Lots of creative things can be done with it, and if you buy a current 
model SSD it likely comes with Opal 2.0 for free.

The USB controllers are hidden only from dom0 (via Xen's PCI device
blacklisting). BIOS or GRUB can, however, still process the device
descriptors or filesystem headers during early boot stages and get
exploited.

AMD seems to have something on the lines of IME:
https://www.reddit.com/r/security/comments/4ot223/do_amdprocessors_have_something_like_intel/

ARM itself is not a specific architecture nor a contained set of them;
for example, a quick google search reveals a thread with your question
on the Raspberry Pi forum:
https://www.raspberrypi.org/forums/viewtopic.php?f=63&t=151542

tl;dr: there does not seem to be some behind-the-scenes management
available for ARM, but this does not stop specific implementations from
having some weirdness like the VideoCore GPU in a RPi - in this case the
GPU "controls" the CPU (it manages CPU boot and manages all CPU RAM at
all times) and is an opaque device.

I just want to make sure that this is not always the case - according to 
https://www.qubes-os.org/doc/usb/, if you create the USB VM automatically 
during install, then Qubes will be set to hide USB devices from dom0 on boot.

You are right. With "proper firewalling" I was implying separate
physical hardware, and that was the basis for "avoid x86 based firewalls".

There's no isolation benefit with a software firewall if the remote
administration packets are received by the local network adapter, since
the "zombie RAT fungus" (Intel ME) fiddles with PCI devices on its own.

Just to be clear for beginners - this means that if you're running Qubes on an 
x86 processor, you cannot trust Qubes as a firewall to prevent IME remote 
administration.

You would need a separate device to act as a firewall. Most routers have 
recently been shown to be compromised in similar ways. It will be difficult, 
but should be possible, to find a device that is secure given current knowledge.

[qubes-users] Qubes 3.2 installation on Lenovo Thinkpad P51

2017-08-30 Thread swami

Hi there,

I'm trying to install Qubes 3.2 on a Lenovo Thinkpad P51, and I know 
that some have succeeded.


But so far my issue is very basic : I can't get the installer to start 
in GUI mode, as X11 fails starting, falling back to the text installaer 
mode which is known to be bugged and unusable (it complains about having 
no disk encryption key provided).


I'm about sure that all I need is a boot option to add to the kernel 
parameters, but googling the group archives didn't help.


Any clue ?

TIA.

Kind regards.
