Enhance Your Security Skills

Cybersecurity Ops with bash teaches you how to leverage sophisticated Linux and Windows commands, and the bash shell to enhance your capabilities as a security operator and practitioner. By learning these skills you will be able to rapidly create and prototype complex capabilities with as little as a single line of pipelined commands.

Master the Command Line

If you hope to outmaneuver threat actors, speed and efficiency are key components of 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.
