Cybersecurity Ops with bash (Attack, Defend, and Analyze from the Command Line)

If you hope to outmaneuver threat actors, speed and efficiency need to be key components of your cybersecurity operations. Mastery of the standard command line interface (CLI) is an invaluable skill in times of crisis because no other software application can match the CLI’s availability, flexibility, and agility. This practical guide shows you how to use the CLI with the bash shell to perform tasks such as data collection and analysis, intrusion detection, reverse engineering, and administration.

Authors Paul Troncone, founder of Digadel Corporation, and Carl Albing, coauthor of bash Cookbook (O’Reilly), provide insight into command line tools and techniques to help defensive operators collect data, analyze logs, and monitor networks. Penetration testers will learn how to leverage the enormous amount of functionality built into every version of Linux to enable offensive operations.

With this book, security practitioners, administrators, and students will learn how to:

• Collect and analyze data, including system logs
• Search for and through files
• Detect network and host changes
• Develop a remote access toolkit
• Format output for reporting
• Develop scripts to automate tasks
