Linux Essentials For Cybersecurity

ALL YOU NEED TO KNOW TO SECURE LINUX SYSTEMS, NETWORKS, APPLICATIONS, AND DATA–IN ONE BOOK

From the basics to advanced techniques: no Linux security experience necessary
Realistic examples & step-by-step activities: practice hands-on without costly equipment
The perfect introduction to Linux-based security for all students and IT professionals

Linux distributions are widely used to support mission-critical applications and manage crucial data. But safeguarding modern Linux systems is complex, and many Linux books have inadequate or outdated security coverage.

Linux Essentials for Cybersecurity is your complete solution. Leading Linux certification and security experts William “Bo” Rothwell and Dr. Denise Kinsey introduce Linux with the primary goal of enforcing and troubleshooting security. Their practical approach will help you protect systems, even if one or more layers are penetrated.

First, you’ll learn how to install Linux to achieve optimal security upfront, even if you have no Linux experience. Next, you’ll master best practices for securely administering accounts, devices, services, processes, data, and networks. Then, you’ll master powerful tools and automated scripting techniques for footprinting, penetration testing, threat detection, logging, auditing, software management, and more.

To help you earn certification and demonstrate skills, this guide covers many key topics on CompTIA Linux+ and LPIC-1 exams. Everything is organized clearly and logically for easy understanding, effective classroom use, and rapid on-the-job training.

LEARN HOW TO:

• Review Linux operating system components from the standpoint of security
• Master key commands, tools, and skills for securing Linux systems
• Troubleshoot common Linux security problems, one step at a time
• Protect user and group accounts with Pluggable Authentication
• Modules (PAM), SELinux, passwords, and policies
• Safeguard files and directories with permissions and attributes
• Create, manage, and protect storage devices: both local and networked
• Automate system security 24/7 by writing and scheduling scripts
• Maintain network services, encrypt network connections, and secure network-accessible processes
• Examine which processes are running–and which may represent a threat
• Use system logs to pinpoint potential vulnerabilities
• Keep Linux up-to-date with Red Hat or Debian software management tools
• Modify boot processes to harden security
• Master advanced techniques for gathering system information

William “Bo” Rothwell At the impressionable age of 14, William “Bo” Rothwell crossed paths with a TRS-80 Micro Computer System (affectionately known as a “Trash 80”). Soon after the adults responsible for Bo made the mistake of leaving him alone with the TRS-80, he immediately dismantled it and held his first computer class, showing his friends what made this “computer thing” work.

Since this experience, Bo’s passion for understanding how computers work and sharing this knowledge with others has resulted in a rewarding career in IT training. His experience includes Linux, Unix, and programming languages such as Perl, Python, Tcl, and BASH. He is the founder and president of One Course Source, an IT training organization.

Denise Kinsey, Ph.D, CISSP, CISCO Dr. Denise Kinsey served as a Unix administrator (HP-UX) in the late 1990s and realized the power and flexibility of the operating system. This appreciation led to her home installation of different flavors of Linux and creation of several academic courses in Linux. With a strong background in cybersecurity, she works to share and implement best practices with her customers and students. Dr. Kinsey is an assistant professor at the University of Houston.
