How to Create a Secure Linux System User - DevDungeon
- https://www.devdungeon.com/content/how-create-secure-linux-system-user
- When deploying a production service in Linux you want to configure itas securely as possible.Ideally, you will create a unique Linux user for each serviceand give them only read and write permission to the exact files they need. You can go even further and create a "system" user that has no home directory,no login shell, and no password. This prevents the user from being able to loginand does not provide a home directory for them to store files. If the service was ever compromised this limits the actions an attacker can takewith the user running the service. This example will show you how to create a system user with: 1. No home directory 2. No logn shell 3. No password (Can't login) We will also cover how to change ownership and permissions for files and directoriesto give your system user write access.
