There are several ways to share a directory across a network. In enterprise settings, you'll find the Network Filesystem (NFS), Samba, and various distributed filesystems. SSHFS isn't used in enterprises quite as much, but it can still come in handy. The beauty of it is that all of its network traffic is encrypted by default, unlike with NFS or Samba. And, other than installing the SSHFS client program and creating a local mount-point directory, it doesn't require any configuration beyond what you've already done. It's especially handy for accessing a directory on a cloud-based Virtual Private Server (VPS) because it allows you to just create files in the shared directory rather than using scp or sftp commands to transfer the files. So, if you're ready, let's jump in.

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.
