• Chris Buechler - Network perimeter redundancy with pfsense

  PDF (6.2 Kb, 30 pages)
  

  This session will first provide an introduction and overview of pfSense and its common uses. It will then go on to cover means of providing redundancy for the critical portions of your network perimeter using pfSense, including redundancy for your Internet connections, firewalls and DNS. Live configuration examples will be shown for as many of these topics as the session's length permits. This session will cover pfSense 1.2.1, but will also offer an overview of some of the enhanced capabilities in this area that pfSense 2.0 will provide in the future.

• Richard Bejtlich - Network security monitoring using FreeBSD

  I've been using FreeBSD as my preferred platform for Network Security Monitoring (NSM) since 2000. In this presentation I'll discuss my latest thinking on using FreeBSD to identify normal, suspicious, and malicious traffic in enterprise networks. FreeBSD is a powerful platform for network traffic inspection and log analysis, and I'll share a few ways I use it in production environments.

• Kristaps Dzonsons - Process isolation for NetBSD and OpenBSD

  In NetBSD and OpenBSD, user-land process and process-context isolation is limited to credential cross-checks, file-system chroot and explicit systrace/kauth applications. I'll demonstrate a working mechanism of isolated process trees in branched OpenBSD-4.4 and NetBSD-5.0-beta kernels where an isolated process is started by a system call similar to fork; following that, the child process and its descendants execute in a context isolated from the caller. This system is the continued work of "mult" -- first prototyped in a branched NetBSD-3.1 kernel and isolating all system resources -- pared down to a lightweight, auditable patch of process-only separation for both OpenBSD and NetBSD. I specifically address solutions to performance issues and mechanism design with an eye toward more resources being isolated in the future.

• Robert Luciani - M:N threading in DragonflyBSD

  Ineffective concurrency mechanisms in an operating system can lead to low performance in both single and multiprocessor environments. Practical setbacks involved with attempting overly invasive kernel changes have made it difficult in the past to implement new and innovative concurrency systems. This paper describes the rationale behind interfaces in the DragonFly BSD operating system intended to provide high performance and scalability on multiprocessor architectures. Using a lock-free processor centric approach, DragonFly BSD has developed a unique thread system with the potential for excellent scalability.

• Brooks Davis - Isolating cluster jobs for performance and predictability

  At The Aerospace Corporation, we run a large FreeBSD based computing cluster to support engineering applications. These applications come in all shapes, sizes, and qualities of implementation. To support them and our diverse userbase we have been searching for ways to isolate jobs from one another in ways that are more effective than Unix time sharing and more fine grained than allocating whole nodes to jobs. In this paper we discuss the problem space and our efforts so far. These efforts include implementation of partial file systems vitalization and CPU isolation using CPU sets.

  Tired of tape and their weaknesses? So am I!

  Epitome is the next generation backup mechanism. It is based on the idea of providing instant available backup data while removing duplicate files & blocks from backups (yes really!). It is a disk based WORM backup system.

  This talk will go into the Epitome protocol and its application. The code is generic enough that it can address all 3 major (buzzword compliant) technologies known as: CAS, DEDUP & SIS.

  In this session, Kurt will discuss OpenBSD's PIE implementation, its impact on existing security mechanisms such as W^X on i386, and the various enhancements needed to the runtime linker, kernel and other system libs.

• Ted Unangst - OpenBSD vs SMP, threading, and concurrency

  I will discuss the current status of kernel SMP support, the rthreads thread library, and relevant future developments. Over the years, we have accumulated several concurrency primitives in the kernel, causing some confusion amongst developers, so I will lay out the origin and correct usage for each. The talk is primarily targeted at the budding OpenBSD kernel developer, but I will also describe the end-user effects of each topic.

• George Neville-Neil - Performance analysis with (hwpmc)

  FreeBSD has included support for Hardware Performance Monitoring Counters (hwpmc) for several years now. The hwpmc system provides access to counters that are present in all modern Intel and AMD CPUs, as well as other chipsets, and which give the programmer the ability to understand the low level performance issues that may effect their code. This talk will cover the motivation behind and basic usage of HWPMC.
