Qubes OS is an open source operating system that provides strong security for desktop computing using the principle of security by compartmentalization. It runs Fedora in a special administrative domain (dom0) and allows other template virtual machines like Debian and Arch Linux. Rather than providing process-level isolation like other operating systems, Qubes OS takes advantage of virtual machine isolation to compartmentalize different tasks and restrict what software can access. This allows it to address security issues with allowing applications to access keystrokes, screenshots, clipboard contents and devices on traditional desktop operating systems.

XPDS16: Hypervisor Enforced Data Loss Prevention - Neil Sikka, A1LOGICThe Linux Foundation
Data Breaches are all over the news these days, and no organization is safe. Nobody, from the largest governments to the biggest banks to the most advanced security companies is able to adequately protect themselves. The difficulty is that there are infinite number of ways to exfiltrate data from an organization ranging from stolen/lost hardware to steganography to malicious insiders to 0Day exploits installing malware to side channels. The industry is trying to solve this problem using detection, heuristics, pattern matching and behavioral analysis. A new approach is clearly needed to fight the Data Breach problem and keep data inside an organization.
Come find out how to use Hypervisors to repurpose hardware to protect sensitive data under the assumption of compromised networks, devices and users (Malicious Insiders). In addition, find out how to do so without using any type of detection, heuristics, pattern matching or behavioral analysis, but rather a strictly algorithmic approach rooted in hardware. Finally, learn about how this technology can be used in a generic manner to protect data of DataBases, Server Software, unmodified legacy applications, and unmodified consumer applications such as word processing and spreadsheet software.
The document describes an Automated Flashing and Testing (AFT) tool that enables continuous integration by automatically deploying and verifying software images on hardware devices. The AFT tool minimizes requirements, easily integrates with existing setups, and scales to support multiple device types and numbers in a cost-effective way. It allows developers to test software builds before submission using the same means as continuous integration. The tool addresses challenges like long build/test times and costs of supporting multiple targets by optimizing the deployment and testing process.
XPDDS19: Implementing AMD MxGPU - Jonathan Farrell, Assured Information SecurityThe Linux Foundation
Jon Farrell summarizes his experience implementing AMD MxGPU virtualization. He began by learning about MxGPU on GitHub and setting up an Ubuntu server with Xen. Initial setup involved building a custom kernel, blacklisting amdgpu, and enabling IOMMU. Guest preparation required installing a VNC server and driver. Difficulties included choosing the right Xen version, starting modules, kernel building, and MxGPU patches. Performance metrics were estimated based on similar benchmarks. Overall, Farrell learned about building Xen, custom kernels, guest VMs, and device passthrough with XL. He sees potential for this technology in cloud gaming platforms and Xen virtualization.

https://archive.org/details/ShmooCon2014_Controlling_USB_Flash_Drive_Controllers
With stories of "BadBIOS" infecting PCs simply by connecting a malicious USB flash drive to a PC, it's time we learned about flash drives and their controllers. Consumer USB flash drives are cheap, growing in capacity and shrinking in physical size. There are only around 15 prominent controller chip manufacturers whom you have never heard of, but OEM for all the popular and respected "name brands" on the market. These flash controllers have capabilities that aren't mentioned on product packaging, and can be enabled with programming you will learn during this presentation. These flash controllers can be *reprogrammed entirely* via software to do whatever you want.
Turn an old flash drive into an emulated CDROM or a CDROM + flash drive. Update the controller's firmware, disassemble it, etc. This talk will touch on the various controller manufacturers, features, and show you how to leverage them for yourself. Why spend $100 on an old SanDisk[tm] U3 Cruiser when you can spend $4 for the same features?

Virtualization allows multiple operating systems to run on a single physical machine by dividing the machine's resources virtually. It works by applying hardware and software partitioning to create isolated execution environments for each virtual system. There are different types of virtualization functions such as sharing, aggregating, emulating, and insulating virtual resources. While virtualization started on mainframes to improve resource utilization, modern virtualization aims to address challenges like rising infrastructure costs and insufficient disaster protection. Virtualization abstracts computer resources and separates privilege levels through defined interfaces, but this also introduces constraints that virtualization aims to overcome.

Virtualization, The future of computing (archived)Bud Siddhisena
Virtualization allows multiple operating systems, called virtual machines, to run simultaneously on a single physical computer. It works by emulating or partially emulating the processor, BIOS, and other hardware for the virtual machines. This provides benefits like better hardware utilization, scalability, fault tolerance, and easier deployment (paragraphs 1-4). Popular virtualization technologies include Qemu, KVM, VirtualBox, and VMWare, which emulate x86, ARM, and PowerPC architectures using native CPU instructions or full emulation (paragraphs 5-7). Virtualization saves costs by improving hardware utilization and allowing dynamic scalability. It also improves maintainability, availability, and deployment times (paragraphs 8-10). Para-virtualization requires modifying

This document discusses different types of virtualization architectures and virtualization concepts. There are three main types of virtualization architectures: 1) traditional virtualization, 2) hosted virtualization, and 3) bare-metal virtualization. It also discusses key virtualization concepts like rings and how they work in virtualized systems. Rings refer to different privilege levels on x86 CPUs, with ring 0 being the most privileged for the operating system kernel. In virtualized systems, the virtual machine monitor runs in ring -1 or ring 0 and guests are fooled into thinking they run in ring 0. Hosted products have performance overhead from the host OS, while bare-metal products like ESX install directly on hardware for higher performance. A
Rmll Virtualization As Is Tool 20090707 V1.0guest72e8c1
Virtualization can be used as a tool for consolidating information systems. There are several common issues that come up with virtualization including ensuring sufficient processor architecture support, network capacity, and dealing with legacy physical hardware. It is important to analyze legacy systems and map application relationships before starting virtualization. Popular hypervisors include KVM, Xen, and OpenVZ. KVM is recommended due to its integration with Linux. Libvirt provides an abstraction layer for different hypervisors. Orchestrators like Enomalism can help manage large virtualized environments through a web interface. Tools were also discussed for snapshotting images, configuring networks, and preventing out-of-memory issues.

Kernel Mode Threats and Practical DefensesPriyanka Aash
Recent advancements in OS security from Microsoft such as PatchGuard, Driver Signature Enforcement, and SecureBoot have helped curtail once-widespread commodity kernel mode malware such as TDL4 and ZeroAccess. However, advanced attackers have found ways of evading these protections and continue to leverage kernel mode malware to stay one step ahead of the defenders. We will examine the techniques from malware such as DoublePulsar, SlingShot, and Turla that help attackers evade endpoint defenses. We will also reveal a novel method to execute a fully kernel mode implant without hitting disk or being detected by security products. The method builds on publicly available tools which makes it easily within grasp of novice adversaries.
While attacker techniques have evolved to evade endpoint protections, the current state of the art in kernel malware detection has also advanced to hinder these new kernel mode threats. We will discuss these new defensive techniques to counter kernel mode threats, including real-time detection techniques that leverage hypervisors along with an innovative hardware assisted approach that utilizes performance monitoring units. In addition, we will discuss on-demand techniques that leverage page table entry remapping to hunt for kernel malware at scale. To give defenders a leg up, we will release a tool that is effective at thwarting advanced kernel mode threats. Kernel mode threats will only continue to grow in prominence and impact. This talk will provide both the latest attacker techniques in this area, and a new tool to curtail these attacks, proving real-world strategies for immediate implementation.
This document provides an overview of virtualization technologies for high performance computing environments. It discusses what virtualization and hypervisors are, as well as common hypervisors like Xen, KVM, and VirtualBox. The document analyzes these hypervisors based on features, usability, and performance benchmarks. Benchmark results are presented from running SPEC CPU, memory, and I/O benchmarks, as well as HPCC benchmarks, on virtual machines created with each hypervisor compared to native hardware. The analysis finds that all hypervisors provide acceptable virtualization features for HPC and that Xen supports the most resources but also has more complex installation.
