We believe that this is currently the only practically viable approach to implementing strong isolation while simultaneously providing compatibility with existing applications and drivers. users to get a laptop that can run Qubes OS well. This also means that it is possible to update the software for several qubes simultaneously by running a single update process in the template upon which those qubes are based. in This could jeopardize all the information stored on or accessed by this computer, such as health records, confidential communications, or thoughts written in a private journal. Kali Linux Landing Page. an upstream project, which just adds to our ongoing maintenance burden. Let's install a secure os on your usb hard drive and take a new test on a secure operating system. Therefore, it is largely outside of our control. Therefore, when you need privacy, you should use Whonix qubes. By contrast, Tor onion service | The rules below will become issue is closed as not our bug.). For further discussion about the potential for GPU passthrough on Xen/Qubes, please see the following threads: No. development works, wonder why we sometimes close issues developers specialize. Tor onion service | One of the most important security improvements that we plan to document.write(new Date().getFullYear()); assigned to your NetVM and USB VM if you move between different machines. easier for users of Qubes 3.2 to evaluate whether their machines will be We discuss this in much greater depth in our Architecture Specification document. All the editions can run on the computer alone, or in a virtual machine. affect Qubes OS. In addition, if your system lacks VT-x/AMD-V, then it also lacks VT-d/AMD-Vi/AMD IOMMU. For me, Qubes is usable as a main OS; it's been my exclusive OS since August 2015 (I ran it from an external drive for about a month before deciding to install it on my internal drive).. Wed have to spend either time or money to implement a solution ourselves or pay someone to do so, and we cant spare either one right now. Privacy policy | A virtual private network (VPN) extends a private network across a public network and enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network. Qubes OS Landing Page. These are known as Type 2 or hosted hypervisors. (As a reminder, its capacity must be at least 32 GiB.) Apart from running Qubes As a free and open-source software project, we rely on donations from users like you in order to keep running. Jabal Omar Development is one of the largest real estate developers, My responsibilities in Jabal Omar include leading the Interior design team (Design, Fit-out, FF&E, and OS&E) and managing the interior designs of the entire project phases, coordinating with the international hotel operators from the design phase up to completion, as well as supervising the design implementation, Develop . In addition, with features like improved ASLR, it is often more difficult to exploit a bug on x64 Linux than x86 Linux. Whenever starting a discussion about another (micro)kernel or hypervisor in relation to Qubes, we strongly suggest including answers to the following questions first: Here are the answers for Xen 4.1 (which we use as of 2014-04-28): Here is an overview of the VM virtualization modes: We have designed the GUI virtualization subsystem with two primary goals: security and performance. 64-bit Intel or AMD processor (x86_64 aka x64 aka AMD64). Qubes uses lightweight VMs to create security qubes (e.g., work, personal, and banking,). . Qubes R4. more TOP Choice Qubes takes an approach called security by compartmentalization, which (You can also in principle remove sys-firewall and only use sys-net combined with sys-usb, even though it will be less secure). Therefore, a system running Qubes without VT-d/AMD-Vi/AMD IOMMU would still be significantly more secure than one running Windows, Mac, or Linux. Full disk encryption is enabled by default. By then, its too late for those who have already been compromised. Qubes are creating from templates. In your templates, open a terminal and run sudo dnf upgrade. I explain the basic usage of Qubes OS, its a fantastic Operating System for Privacy and Security that creates security thro. By release series. Please see the system requirements for the latest information. After Tails using this comparison chart. SLAT (EPT) is an extension to Intel VT-x virtualization, which See introductions on Wikibooks: here, here and here. This approach allows you to keep the different things you do on your computer securely separated from each other in isolated qubes so that one qube getting compromised wont affect the others. obligatory for hardware to be certified for the upcoming Qubes 4.x branch. The Qubes OS Project and others table construction. The number of machines coreboot currently supports is limited and the use of some vendor supplied blobs is generally still required. For example, if you use your computer to conduct financial transactions, the malware might allow its creator to make fraudulent transactions in your name. For the user, both programs seem to be running on the same workspace. Press OK to reboot the system. affects me! This means that, without VT-x/AMD-V, no VMs will start in a default Qubes installation. We do not provide GPU virtualization for Qubes. is a list of Intel processors that meet the minimum requirements for The System requirements | Qubes OS specifies 32 GB as the "minimum" storage requirements and 128+ GB as recommended (with an SSD being strongly recommended). There is hardly a discussion needed in this regard - Qubes enables all these requirements in a very flexible, liberal and secure way: You choose the underlying OS that you want to use as a baseline. Physically separate computers running conventional OSes are still independently vulnerable to most conventional attacks due to their monolithic nature. Users who plan on using Qubes in an air-gap scenario expect the first release candidate (4.0-rc1) to be out in September and the With Qubes, you're not limited to just one OS. Categories: Linux Operating Systems Linux Distribution. (e.g. Qubes takes an approach called security by compartmentalization, which allows you to compartmentalize the various parts of your digital life into securely isolated compartments called qubes. The recommended approach is to pass only the specific partition you intend to use from sys-usb to another qube via qvm-block. Terms of use | (Recommended) Clone an existing Debian template, (Recommended) Clone an existing Fedora template, Attach USB device to qube - it should be attached as, Q System Tools Window Manager Tweaks Compositor uncheck Enable display compositing. The other two popular approaches are Security by Correctness and Security by Obscurity. kernel protection do not require special hardware. Another important requirement were introducing today is that Qubes-certified View all repositories. E.g. This has nothing to do with Qubes. upstream but hasnt yet arrived in your Qubes OS release, please see If its recognized, they scramble their code until its no longer recognizable by the antivirus programs, then send it out. The 64-bit option provides some (little perhaps, but some) more protection against some classes of attacks, and at the same time does not have any disadvantages except the extra requirement of a 64 bit processor. The Qubes OS Project is now accepting donations on Ethereum! ask, Why dont you fix every upstream bug that affects Qubes OS? In light the bare necessities that a device must meet in order to run Qubes at all. There are two distinct senses of the word free when it comes to free software. The problem is fixed in Stretch, and does not affect Fedora-based qubes. Fully virtualized VMs (HVMs)? Our platform supports it, but weve decided not to enable it. If you need to support not-fully-updated systems, check for the existence of /usr/bin/qrexec-client-vm. However, this could theoretically lead to an attack because it forces the destination qube to parse the devices partition table. The Qubes OS Project and others Qubes OS is regarded as one of the most secure oper. introducing additional conditions, designed to also make such devices actually the greatest benefit, on doing security-related work that only they can do. The four essential freedoms are part of the core of our philosophy, but so is security. Because the host system does not have network access, only a few components need updates, which the admin installs at the command line. Specifically: Since 2013 Xen has not supported 32-bit x86 architecture and Intel VT-d, which Qubes uses to isolate devices and drivers, is available on Intel 64-bit processors only. document.write(new Date().getFullYear()); If it seems like the issue described in this thread, try disabling the window compositor: Please report (via the mailing lists) if you experience this issue, and whether disabling the compositor fixes it for you or not. supported by the 4.x series. Recommended system requirements are typically less specific than hardware Such systems will still offer significant security improvements Qubes aims to maximize both security and software freedom to the extent that they are compatible in the world today. So, if feature X isnt enabled, its most likely for one of three reasons: If it seems like a feature that we can and should enable, please let us know! And what underlying h/w technology is used (ring0/3, VT-x)? Personally, I have found that, with Qubes OS R4.0.4, that 32 GB is not enough to install all of the default templates, so I would say 64 GB should be considered the bare minimum. Those wont fly. Xubuntu (/ z b n t u /) is a Canonical Ltd.-recognized, community-maintained derivative of the Ubuntu operating system.The name Xubuntu is a portmanteau of Xfce and Ubuntu, as it uses the Xfce desktop environment, instead of Ubuntu's Unity and GNOME desktop.. Xubuntu seeks to provide "a light, stable and configurable desktop environment with conservative workflows" using Xfce . Similarly, if youre concerned about malicious email attachments, Qubes can make it so that every attachment gets opened in its own single-use disposable qube. Also see: Will Qubes seek to get certified under the GNU Free System Distribution Guidelines (GNU FSDG)? Runs unmodified usermode apps (binaries). It begins with an explanation of the risks with such a setup. A 100% free operating system that excludes all such blobs is vulnerable to known exploits and is therefore unsuitable for any use case where security matters. Besides, they own the report, will be updated in Qubes 3.2. already use internally) or a separate USB controller only for input devices. And even though Qubes now needs a 64 bit processor, it didnt make sense to run Qubes on a system without 3-4GB of memory, and those have 64-bit CPUs anyway. (See next question.). Programs are isolated in their own separate qubes, but all windows are displayed in a single, unified desktop environment with unforgeable colored window borders so that you can easily identify windows from different security levels. But if you understand the risk and accept it, read documentation on multibooting. As a free and open-source project, our valued community of users and contributors from around the world are in the best position to help. important to the Qubes user experience. (and which we require). The r-10 supports several different operating systems; you can choose from Qubes OS, Ubuntu, or Windows 10 pre-installed. Specifically, we use LUKS/dm-crypt. Still need that one Windows program for work? This would not make much sense. Minimum system requirements are the least stringent. A device which was previously assigned to a less trusted qube could attack dom0 if it were automatically reassigned there. It also has a very unique GUI virtualization infrastructure. has shown that this works very well. world: There are a huge number of different open-source projects that each devices but merely recommended for non-certified Qubes-specific features - a change in one supported distribution should be own bare-metal hypervisor (Xen). Yes, Qubes natively supports automation via Salt (SaltStack). : https. In the 4.x release series, both people, especially those who arent familiar with how open-source software 2016-09-02 Moreover, the question is based on a faulty assumption in the first place, It is very difficult to securely implement multi-user support. youll also be helping all downstream users of that software! In addition to the convenience back then was actually less attractive than the PV approach). For example, popular live OSes (such as Tails and other Linux distributions) are still monolithic in the sense that all software is still running in the same OS. Ubuntu is a popular operating system for cloud computing, with .

(For example, you might find it natural to lock your secure laptop in a safe when you take your unsecure laptop out with you.). But since you can read the whole memory, it isnt that hard. Yes. laptops on the market that we have seen satisfy this condition out of the box, Qubes 4.x, QSB-086: Speculative security issues on AMD CPUs (XSA-422), QSB-085: Xenstore: Guests can crash xenstored (XSA-414), New user guide: How to organize your qubes. verify the PGP signatures on the commits and/or tags, intentionally written in Markdown so as to be readable as plain text for this very reason, Enable the appropriate RPMFusion repos in the desired Fedora template. exposed through our carefully designed protocol only to select AppVMs when the Kodachi is a live operating system that you can start on almost any computer from a DVD, USB stick, or SD card. See Admin API and Core Stack for more details. convenient mechanical switch. Qubes has been installed on the flash drive, it can then be plugged into This includes disposables. However, in Qubes 4.x we will be implementing management functionality. So as soon as you boot into this operating system, it boots into Xen, which is a hypervisor, and then once the operating system starts. Our GUI infrastructure introduces only about 2,500 lines of C code (LOC) into the privileged domain (Dom0), which is very little, and thus leaves little space for bugs and potential attacks. aspects of Qubes OS engineering work for which they are uniquely qualified. Users are advised to check the specifications of any AMD Please see the coreboot website / their IRC channel for further information. releases. (This list should automatically be updated whenever and hence required a complex Shadow Page Tables approach (which we believed unreasonable expectation. Were less likely to introduce Qubes-specific issues. The Qubes OS Project and others reports for We dont consider this a problem, however, since we explicitly distrust the infrastructure. In short: we believe the Xen architecture allows for the creation of more secure systems (i.e. Intel releases new processors.) Of course, to be compatible with Qubes OS, the BIOS must properly expose Very well, you might be thinking, but theres still an upstream bug that You may need to install a binary blob, which provides drivers, from the linux-firmware package. Qubes OS is a free and open-source, security-oriented operating system for single-user desktop computing. See here for details. Privacy policy | Learn more. In short: these are non-realistic solutions today. roadmap. the open-source world works. Still need that one Windows program for work? Will Qubes seek to get certified under the GNU Free System Distribution Guidelines (GNU FSDG)? Qubes OS Project is small, lean, and focused on one goal: creating and What kinds of containers does it use for isolation? easy-to-flip-by-mistake switches, while others should benefit from the Qubes Qubes OS is mostly free as in speech, but not entirely. Installing and Using Anti Evil Maid (AEM) with Qubes OS Background Please read this blog article. Not only will you be helping all other affected Qubes users, While we designed Qubes from the beginning to limit potential attack vectors, we still realize that some of the code running in Dom0, e.g. Although you can also attach the entire USB device to a qube by selecting it from the bottom part of the list, in general this approach should not be used because you are exposing the target qube to unnecessary additional attack surface. documentation. . details). Qubes is a security-oriented, free and open-source operating system for personal computers that allows you to securely compartmentalize your digital life. Its free (as in beer). store) before deciding on which computer to purchase. Moreover, all of these isolated qubes are integrated into a single, usable system. Moreover, Intel VT-x must support Extended Page Tables introduce with the release of Qubes 4 is to ditch paravirtualization (PV) The innovative Template system separates software installation from software use, allowing qubes to share a root filesystem without sacrificing security (and saving disk space, to boot). Very paranoid users, or those who are high-profile targets, might use a dozen or more qubes. Everything inside this operating system is separated into different domains, you'll have a domain for work at domain . Compare Qubes OS vs. The upstream documentation matches the distribution running in the Qubes VM. the piece of software using it said to be downstream. For example, Qubes OS Now, how does this apply to Qubes OS? Qubes brings to your personal computer the security of the Xen hypervisor, the same software relied on by many major hosting providers to isolate websites and services from each other. Report a problem | Theres generally no secure way to transfer data between physically separate computers running conventional OSes. hardware (see the hardware certification In contrast to some of the large upstream projects whose software we use, the We previously announced the new hardware certification requirements for Qubes CPU-vendor code can cause, we are also pragmatic enough to realize that we need obscure this fact or avoid using upstream software in favor of doing everything Announcements, Still others focus on combining many different tools ark.intel.com. Then, we could just install Qubes without having to install any programs in it or adjust any settings. Sitemap, High-speed solid-state drive strongly recommended, AMD GPUs have not been formally tested, but Radeons (especially RX580 and submitting HCL Minimum CPU: 64-bit Intel or AMD processor (also known as x86_64, x64, and AMD64 ) Intel VT-x with EPT or AMD-V with RVI Intel VT-d or AMD-Vi (also known as AMD IOMMU) Memory: 6 GB RAM Storage: 32 GB free space Recommended Qubes OS is a security-focused operating system that allows you to organize your digital life into compartments called "qubes." If one qube is compromised, the others remain safe, so a single cyberattack can no longer take down your entire digital life in one fell swoop. Intel Integrated Graphics Processor (IGP) is recommended. This is probably because one of the controllers does not support reset. of software, the piece of software being used is said to be upstream, while PV and HVM Virtual Machines (ring0/3 for PV domains, VT-x/AMD-v for HVMs). a huge upstream project with ample time and resources, and that the upstream Then load the ISO file by clicking browse and load the Qube OS ISO file. Hackers are unable to steal information or attack the system as a result of this. While we also recommend a physical kill switch on the built-in camera (or, if Whonix is an easy way to force all your traffic to go through Tor. Below is the minimum and recommended specifications needed to run Qubes OS: 64-bit Intel or AMD processor (aka x86_64, x64, AMD64). Non-USB keyboard. please see the new hardware certification requirements for Qubes 4.x However, the fact that Type 2 hypervisors run under the host OS means that theyre really only as secure as the host OS itself. It is free and open-source software (FOSS) that means anyone can use it for free, copy, distribute or change in any way. Website source code | Qubes brings to your personal computer the security of the Xen hypervisor, the same software relied on by many major hosting providers to isolate websites and services from each other. Figure 3: The architecture of Qubes OS: Depending on their security requirements, applications are assigned to app VMs; Qubes abstracts hardware with its own VMs. Report a problem | Tor onion service | The text of this QSB is reproduced below. Officially supported template VMs include Debian, Fedora . requirements, we aim to set the highest reasonable standard of security and Terms of use | You shouldnt do that, because it poses a security risk for your Qubes OS installation. Common attack vectors like network cards and USB controllers are isolated in their own hardware qubes while their functionality is preserved through secure networking, firewalls, and USB device management. The following are required for Qubes-certified hardware However, it should be noted that the majority of 32GB eMMC flash memory, This ultracompact memory system is ideal for mobile devices and applications, providing enhanced storage capabilities, streamlined data management, quick boot-up times and support for high-definition video playback. But this isnt that hard, because there is a lot of complex code handling network traffic. We have just published Qubes Security Bulletin (QSB) 086: Speculative security issues on AMD CPUs (XSA-422). Some users have been able to do this, but it is neither recommended nor supported. You can install the Qubes OS on systems that do not meet the recommended requirements, the developers noted. For this reason, we generally do not grant requests for peoples favorite programs to be installed by default or for some setting that obviously varies by user preference to be changed so that it matches the requesters preference. You can probably run two useful qubes with it and get a more secure environment than on regular operating systems. fixes into the entire code base for maintainability.
