## 3. Set-up Security Groups
All network traffic is blocked in OpenStack by default. You need to explicitly grant access to individual services by utilising Security Groups. This is similar to setting up firewall rules on your router or server. If setup correctly, you can access your virtual machine via SSH connection from your terminal.[^2]

## Project
## Project
A project (a.k.a. an account) is a group of zero or more users. In Compute, a project owns virtual machines. In Object Storage, a project owns containers. Users can be associated with more than one project. Each project and user pairing can have a role associated with it.
## Role
Roles define which actions users can perform. You assign roles to user-project pairs.
