  • Enhance file system security and local and remote user authentication by using various security tools and different versions of Linux for different tasks

Book Description

With the growing popularity of Linux, more and more administrators have started moving to the system to create networks or servers for any task. This also makes Linux the first choice for any attacker now. Due to the lack of information about security-related attacks, administrators now face issues in dealing with these attackers as quickly as possible. Learning about the different types of Linux security will help create a more secure Linux system.

Whether you are new to Linux administration or experienced, this book will provide you with the skills to make systems more secure.

With lots of step-by-step recipes, the book starts by introducing you to various threats to Linux systems. You then get to walk through customizing the Linux kernel and securing local files. Next you will move on to manage user authentication locally and remotely and also mitigate network attacks. Finally, you will learn to patch bash vulnerability and monitor system logs for security.

With several screenshots in each example, the book will supply a great learning experience and help you create more secure Linux systems.

What you will learn

  • Learn about various vulnerabilities and exploits in relation to Linux systems
  • Configure and build a secure kernel and test it
  • Learn about file permissions and security and how to securely modify files
  • Explore various ways to authenticate local users while monitoring their activities.
  • Authenticate users remotely and securely copy files on remote systems
