The most complete, authoritative technical guide to the FreeBSD kernel's internal structure has now been extensively updated to cover all major improvements between Versions 5 and 11. Approximately one-third of this edition's content is completely new, and another one-third has been extensively rewritten. Three long-time FreeBSD project leaders begin with a concise overview of the FreeBSD kernel's current design and implementation. Next, they cover the FreeBSD kernel from the system-call level down-from the interface to the kernel to the hardware. Explaining key design decisions, they detail the concepts, data structures, and algorithms used in implementing each significant system facility, including process management, security, virtual memory, the I/O system, filesystems, socket IPC, and networking. This Second Edition * Explains highly scalable and lightweight virtualization using FreeBSD jails, and virtual-machine acceleration with Xen and Virtio device paravirtualization * Describes new security features such as Capsicum sandboxing and GELI cryptographic disk protection * Fully covers NFSv4 and Open Solaris ZFS support * Introduces FreeBSD's enhanced volume management and new journaled soft updates * Explains DTrace's fine-grained process debugging/profiling * Reflects major improvements to networking, wireless, and USB support Readers can use this guide as both a working reference and an in-depth study of a leading contemporary, portable, open source operating system. Technical and sales support professionals will discover both FreeBSD's capabilities and its limitations. Applications developers will learn how to effectively and efficiently interface with it; system administrators will learn how to maintain, tune, and configure it; and systems programmers will learn how to extend, enhance, and interface with it.

Kyle Rankin
R873 Discovery Miles 8 730 Ships in 9 - 15 working days

Implement Industrial-Strength Security on Any Linux Server In an age of mass surveillance, when advanced cyberwarfare weapons rapidly migrate into every hacker's toolkit, you can't rely on outdated security methods-especially if you're responsible for Internet-facing services. In Linux (R) Hardening in Hostile Networks, Kyle Rankin helps you to implement modern safeguards that provide maximum impact with minimum effort and to strip away old techniques that are no longer worth your time. Rankin provides clear, concise guidance on modern workstation, server, and network hardening, and explains how to harden specific services, such as web servers, email, DNS, and databases. Along the way, he demystifies technologies once viewed as too complex or mysterious but now essential to mainstream Linux security. He also includes a full chapter on effective incident response that both DevOps and SecOps can use to write their own incident response plan. Each chapter begins with techniques any sysadmin can use quickly to protect against entry-level hackers and presents intermediate and advanced techniques to safeguard against sophisticated and knowledgeable attackers, perhaps even state actors. Throughout, you learn what each technique does, how it works, what it does and doesn't protect against, and whether it would be useful in your environment. Apply core security techniques including 2FA and strong passwords Protect admin workstations via lock screens, disk encryption, BIOS passwords, and other methods Use the security-focused Tails distribution as a quick path to a hardened workstation Compartmentalize workstation tasks into VMs with varying levels of trust Harden servers with SSH, use apparmor and sudo to limit the damage attackers can do, and set up remote syslog servers to track their actions Establish secure VPNs with OpenVPN, and leverage SSH to tunnel traffic when VPNs can't be used Configure a software load balancer to terminate SSL/TLS connections and initiate new ones downstream Set up standalone Tor services and hidden Tor services and relays Secure Apache and Nginx web servers, and take full advantage of HTTPS Perform advanced web server hardening with HTTPS forward secrecy and ModSecurity web application firewalls Strengthen email security with SMTP relay authentication, SMTPS, SPF records, DKIM, and DMARC Harden DNS servers, deter their use in DDoS attacks, and fully implement DNSSEC Systematically protect databases via network access control, TLS traffic encryption, and encrypted data storage Respond to a compromised server, collect evidence, and prevent future attacks Register your product at informit.com/register for convenient access to downloads, updates, and corrections as they become available.

The "Ubuntu 11.04 Desktop: Applications and Administration" covers the Ubuntu 11.04 (Natty Narwhal) release, focusing on applications and administrative tools. The emphasis here is on what users will face when using Ubuntu, covering topics like installation, applications, software management, the Ubuntu desktops (Unity, GNOME, and KDE), shell commands, network connections, and system administration tasks. Ubuntu 11.04 introduces several new features, as well as numerous smaller modifications. It is a short-term support release. The Ubuntu desktop with the new Unity interface is examined in detail, along with the Ubuntu Classic desktop, which uses GNOME 2.3. Unity uses a Launcher and a Dash (dashboard) to manage access to applications and devices. The Kubuntu desktop, which uses KDE, provides a very different interface using plasma containers to support the panel, menu, desktop, configuration tools, and plasmoid applets. Changes include and the new Unity interface with launcher and dash, refinements to the Ubuntu Software Center, Ubuntu One setup and configuration, the Banshee music and media player, LibreOffice (replacement for OpenOffice), Firefox 4 with syncing, and the new time and date application. Ubuntu 11.04 provides improvements to the Software Center, Ubuntu One setup and configuration, and the installation procedure. Banshee is the new default music player. Advanced components are also examined such as the GRUB 2 boot loader, Computer Janitor for removing unused software, PulseAudio sound configuration, and Disk Utility (Udisks) for storage device configuration and information (SMART).
