This document discusses VirtFS, a paravirtual file system that allows file system access between a KVM hypervisor and guest virtual machines. It uses the 9P protocol for communication and the VirtIO transport for efficient data transfer. The file system is exported from the host to guests using QEMU and provides security isolation of guest credentials from the host through user ID mapping.
Dealing with Hardware Heterogeneity Using EmbeddedXEN, a Virtualization Frame...The Linux Foundation
EmbeddedXEN is a particularly efficient virtualization framework tailored to ARM-based core embedded systems.
While security and OS isolation are key features of conventional virtualizuation frameworks, the main concerns for EmbeddedXEN are device heterogeneity and realtime aspects, which are particularly important in the embedded world.
EmbeddedXEN mainly relies on the original XEN architecture but with major differences in the way guest OS are handled: the hypervisor has been simplified, and only two guest OS (dom0 and domU) can run simultaneously; while dom0 is used to manage the native OS with drivers (original and backend splitted drivers), a paravirtualized OS (domU) can be cross-compiled on a different ARM device, and user applications can run seamlessly on the (virtualized) host device. Another important difference is that no user space tools are required to manage the VMs; the framework produces a compact single binary image containing both dom0 and domU guests, which can be easily deployed. The Xenbus architecture has been adapted to that context.
EmbeddedXEN therefore allows the porting of an OS and its applications from an ARM embedded device to last generation ARM hardware, such as HTC Smartphone for example.
Not all networks are created equal. Brocade Ethernet Fabrics, as joined in the IBM Flex EN4023 embedded switch, revolutionizes by automating and optimizing your network, enabling you to reduce total cost of ownership, not just capital expenses. Lab tests have validated the Opex and Capex advantages of VCS Ethernet Fabrics over traditional networking. Learn how customers have reduced network infrastructure requirements by 25% and increases the networks performance by up to 30%. See how Dynamic Ports on Demand can save hardware costs. Learn the dramatic Operational impact VCS Fabric switches have on decreasing time to deploy the network by 79% and decreasing the time to implement network changes by 85%.
This session provides a schematic overview of the security properties, architecture, tweaks and settings of a SUSE Linux Enterprise 11 installation. It will also deliver a systematic, hands-on experience for analyzing and adjusting these security properties. This session will cover both networked and non-networked security properties, and may be applied to both the desktop and the server use of the system.

This talk will discuss the challenges of client virtualization and introduce at a technical level XenClient XT, a security-oriented client virtualization product by Citrix. By describing XenClient XT architecture and features, it will be shown how the unique Xen's design and its support for modern x86 platform hardware can increase security and isolation among VMs.
Disaggregation of services provided by the platform will be a key of this talk. It will also be shown how third party software components can provide services to VMs in a secure and controlled way.

A tale of scale & speed: How the US Navy is enabling software delivery from l...sonjaschweigert1
Rapid and secure feature delivery is a goal across every application team and every branch of the DoD. The Navy’s DevSecOps platform, Party Barge, has achieved:
- Reduction in onboarding time from 5 weeks to 1 day
- Improved developer experience and productivity through actionable findings and reduction of false positives
- Maintenance of superior security standards and inherent policy enforcement with Authorization to Operate (ATO)
Development teams can ship efficiently and ensure applications are cyber ready for Navy Authorizing Officials (AOs). In this webinar, Sigma Defense and Anchore will give attendees a look behind the scenes and demo secure pipeline automation and security artifacts that speed up application ATO and time to production.
We will cover:
- How to remove silos in DevSecOps
- How to build efficient development pipeline roles and component templates
- How to deliver security artifacts that matter for ATO’s (SBOMs, vulnerability reports, and policy evidence)
- How to streamline operations with automated policy checks on container images

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
