Preface

Introduction


The recipes in this chapter will help you provide remote access to your CentOS system in a security-conscious way. You'll learn how to execute commands on a remote system through SSH, configure the OpenSSH SSH server to increase security surrounding remote logins, and use key-based authentication to connect. You'll also learn how to allow or deny access to different users, configure Fail2ban to automatically block suspected IP addresses to protect your server from brute force attacks better, and restrict users to a chroot jail once they've logged in. The concluding recipes show you how to provide remote access to a complete desktop environment using VNC, and how to secure that access by tunneling VNC traffic through an SSH tunnel.
