A comprehensive guide to securing your Linux system against cyberattacks and intruders
From creating networks and servers to automating the entire working environment, Linux has been extremely popular with system administrators for the last couple of decades; however, security has always been a major concern. With not many resources available in the Linux security domain, this book will be an invaluable guide to help you get your Linux systems properly secured.
Complete with in-depth explanation of essential concepts, practical examples, and self-assessment questions, this book begins by helping you set up a practice lab environment and takes you through the core functionalities of securing Linux. You,ll practice various Linux hardening techniques and advance to setting up a locked-down Linux server. As you make progress, you will also learn how to create user accounts with appropriate privilege levels, protect sensitive data by setting permissions and encryption, and configure a firewall.
