Overview of this book

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 limited resources available in the Linux security domain, this book will be an invaluable guide in helping you get your Linux systems properly secured. Complete with in-depth explanations 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 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. The book will help you set up mandatory access control, system auditing, security profiles, and kernel hardening, and finally cover best practices and troubleshooting techniques to secure your Linux environment efficiently. By the end of this Linux security book, you will be able to confidently set up a Linux server that will be much harder for malicious actors to compromise.

Although, understand that, even though this sounds like a cool idea, creating files in the normal way will cause files to have the read/write permissions set for the group, and the read permission set for others. So, if you're setting this up for a directory where users just create files normally, the best that you can hope to do is to create an ACL that adds either the write or execute permissions for someone. Either that or ensure that users set the 600 permissions settings on all files that they create, assuming that users really do need to restrict access to their files.

On the other hand, if you're creating a shell script that creates files in a specific...
