Knoppix is a portable Linux distribution replete with hundreds of valuable programs and utilities -- a veritable Swiss Army knife in bootable CD form. It includes Linux software and desktop environments, automatic hardware detection and hundreds of other quality open source programs.

Whether you're a system administrator or power user, you can use Knoppix for many different purposes. Knoppix boots and runs completely from a single CD so you don't need to install anything to your hard drive. Due to on-the-fly decompression, the CD can have up to 2 GB of executable software installed on it.

What you do need, however, is a comprehensive reference guide so you can benefit from all that Knoppix has to offer. The "Knoppix Pocket Reference" from O'Reilly fits the bill. This handy book shows you how to use Knoppix to troubleshoot and repair your computer, how to customize the Knoppix CD, running RAM memory checks, recovering data from a damaged hard drive, cloning hard drives, using Knoppix as a Terminal Server, using Knoppix as a kiosk OS, scanning for viruses on a Windows system, editing the Registry of a Windows system, and much more.

If you want more information than the average Knoppix user, "Knoppix Pocket Reference" is an absolutely essential addition to your personal library.

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of mass surveillance, when advanced cyberwarfare weapons rapidly migrate into every hacker's toolkit, you can't rely on outdated security methods-especially if you're responsible for Internet-facing services.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.
