-OpenStack projects group VMs together and provide a quota out of which VMs and related resources can be created. A project is unique to a particular cloud. All accounts which are members of a project have the same level of permissions, meaning anyone can create or delete a VM within a project if they are a member. You can view the projects you are a member of by logging into an OpenStack dashboard for the clouds you have access to (see [[Cloud#Cloud_systems|Cloud systems]] for a list of cloud URLs). The active '''project name''' will be displayed in the top left of the dashboard, to the right of the cloud logo. If you are a member of more than one project, you can switch between active projects by clicking on the drop-down menu and selecting the project's name.

-The '''default security group''' contains rules which allow a VM access out to the internet, for example to download operating system upgrades or package installations, but does not allow another machine to access it, except for other VMs belonging to the same default security group. We recommend you do not remove rules from the default security group as this may cause problems when creating new VMs. The image on the right shows the default security group rules that should be present:
