7. The Visible Ops Handbook, by Kevin Behr, Gene Kim, George Spafford

Book Description: The Core of Visible Ops Visible Ops is a methodology designed to jumpstart implementation of controls and process improvement in IT organizations needing to increase service levels, security, and auditability while managing costs. Visible Ops is comprised of four prescriptive and self-fueling steps that take an organization from any starting point to a continually improving process. Making ITIL Actionable Although the Information Technology Infrastructure Library (ITIL) provides a wealth of best practices, it lacks prescriptive guidance: What do you implement first, and how do you do it? Moreover, the ITIL books remain relatively expensive to distribute. Other information, publicly available from a variety of sources, is too general and vague to effectively aid organizations that need to start or enhance process improvement efforts. The Visible Ops booklet provides a prescriptive roadmap for organizations beginning or continuing their IT process improvement journey. Why Do You Need Visible Ops? The Visible Ops methodology was developed because there was not a satisfactory answer to the question: “I believe in the need for IT process improvement, but where do I start?” Since 2000, Gene Kim and Kevin Behr have met with hundreds of IT organizations and identified eight high-performing IT organizations with the highest service levels, best security, and best efficiencies. For years, they studied these high-performing organizations to figure out the secrets to their success. Visible Ops codifies how these organizations achieved their transformation from good to great, showing how interested organizations can replicate the key processes of these high-performing organizations in just four steps: 1. Stabilize Patient, Modify First Response – Almost 80% of outages are self-inflicted. The first step is to control risky changes and reduce MTTR by addressing how changes are managed and how problems are resolved. 2. Catch and Release, Find Fragile Artifacts – Often, infrastructure exists that cannot be repeatedly replicated. In this step, we inventory assets, configurations and services, to identify those with the lowest change success rates, highest MTTR and highest business downtime costs. 3. Establish Repeatable Build Library – The highest return on investment is implementing effective release management processes. This step creates repeatable builds for the most critical assets and services, to make it “cheaper to rebuild than to repair.” 4. Enable Continuous Improvement – The previous steps have progressively built a closed-loop between the Release, Control and Resolution processes. This step implements metrics to allow continuous improvement of all of these process areas, to best ensure that business objectives are met.

8. Automating Linux and Unix System Administration, by Nathan Campi, Kirk Bauer

Book Description: Whether you need a network of ten Linux PCs and a server or a data center with a few thousand UNIX nodes, you need to know how to automate much of the installation, configuration, and standard system administration.

Build your network once using cfengine, and the network build will work, without user intervention, on any hardware you prefer. Automating Linux and Unix System Administration, Second Edition is unique in its focus on how to make the system administrator’s job easier and more efficient: instead of just managing the system administrator’s time, the book explains the technology to automate repetitive tasks and the methodology to automate successfully.

- Both new and seasoned professionals will profit from industry–leading insights into the automation process.

- System administrators will attain a thorough grasp of cfengine, kickstart, and shell scripting for automation.

- After reading all chapters and following all exercises in this book, the reader will be able to set up anything from a Linux data center to a small office network.

What you’ll learn

See how to make changes on many UNIX and Linux hosts at once in a reliable and repeatable manner.

- Learn how to automate things correctly so you only have to do it once, by leveraging the authors’ experience in setting up small, medium, and large networks.

- Set up a Linux data center or a network correctly.

- Explore handling real–world environments where not all hosts are configured alike via a case study of a fictional new data center build-out.

- Examine real–world examples for core infrastructure services (DNS, mail, monitoring, log analysis, security, cfengine, imaging) to build on in your environment.

- Understand core system administration best practices, which are a key part of how cfengine and automations deployments are outlined in the book.

- Learn how to make changes reversible, repeatable, and correct the first time through interaction with product/application stakeholders (programmers, product managers, customers, etc.).

Who this book is for

This book is for Linux system administrators who want to learn about the software and methodology to automate repetitive tasks—regardless of network or data center size—in one place. System managers will also find it much easier to think about network technology and automation projects if they read this book. This book is also for anyone who is interested in repeatable and secure infrastructure.

9. Python for Unix and Linux System Administration, by Noah Gift, Jeremy Jones

Book Description: Python is an ideal language for solving problems, especially in Linux and Unix networks. With this pragmatic book, administrators can review various tasks that often occur in the management of these systems, and learn how Python can provide a more efficient and less painful way to handle them. Each chapter in Python for Unix and Linux System Administration presents a particular administrative issue, such as concurrency or data backup, and presents Python solutions through hands-on examples. Once you finish this book, you'll be able to develop your own set of command-line utilities with Python to tackle a wide range of problems. Discover how this language can help you: Read text files and extract information Run tasks concurrently using the threading and forking options Get information from one process to another using network facilities Create clickable Guis to handle large and complex utilities Monitor large clusters of machines by interacting with Snmp programmatically Master the Ipython Interactive Python shell to replace or augment Bash, Korn, or Z-Shell Integrate Cloud Computing into your infrastructure, and learn to write a Google App Engine Application Solve unique data backup challenges with customized scripts Interact with MySql, Sqlite, Oracle, Postgres, Django Orm, and Sqlalchemy With this book, you'll learn how to package and deploy your Python applications and libraries, and write code that runs equally well on multiple Unix platforms. You'll also learn about several Python-related technologies that will make your life much easier.

10. Linux Firewalls, by Michael Rash

Book Description: System administrators need to stay ahead of new security vulnerabilities that leave their networks exposed every day. A firewall and an intrusion detection systems (IDS) are two important weapons in that fight, enabling you to proactively deny access and monitor network traffic for signs of an attack.

Linux Firewalls discusses the technical details of the iptables firewall and the Netfilter framework that are built into the Linux kernel, and it explains how they provide strong filtering, Network Address Translation (NAT), state tracking, and application layer inspection capabilities that rival many commercial tools. You'll learn how to deploy iptables as an IDS with psad and fwsnort and how to build a strong, passive authentication layer around iptables with fwknop.

Concrete examples illustrate concepts such as firewall log analysis and policies, passive network authentication and authorisation, exploit packet traces, Snort ruleset emulation, and more with coverage of these topics:

- Passive network authentication and OS fingerprinting

- iptables log analysis and policies

- Application layer attack detection with the iptables string match extension

- Building an iptables ruleset that emulates a Snort ruleset

- Port knocking vs. Single Packet Authorization (SPA)

- Tools for visualising iptables logs

Perl and C code snippets offer practical examples that will help you to maximize your deployment of Linux firewalls. If you're responsible for keeping a network secure, you'll find Linux Firewalls invaluable in your attempt to understand attacks and use iptables-along with psad and fwsnort-to detect and even prevent compromises.
