Security Groups

A security group is a set of firewall rules on a set of instances. Security groups enable to create rules that either drop or allow incoming traffic from certain ports of your instances.

Security Group Schema

  • id String - A unique identifier for each security group. This is automatically generated.
  • name String - The human-readable name for the security group.
  • description String - The human-readable description for the security group.
  • region String - The identifier for the region this security group exists in (eg. ARC-IS-HAF-1).
  • status String - The security group status. Possible values are creating, created and deleting.
  • rules Array - The security group rules.
  • created_at String - A time value given in ISO8601 combined date and time format that represents when the security group was created.

For legacy projects and accounts there are additional statuses updating and error.
