TARGET HOST A target host is a specific type of target resource that provides access to a Linux or Windows operating system using SSH (port 22 by default). TARGET RESOURCE A target resource is an entity that resides in your organization's VCN (virtual cloud network), which you can connect to by using a In addition to presenting the private key, an authorized user must also attempt the SSHĬonnection to the target resource from an IP address within the range allowed by the bastion's client CIDR block allowlist.

In a security zone cannot have public endpoints. For example, you can use a bastion to access Compute instances in compartments that are associated with a security zone. Targets can include resources like compute instances, DB systems, and Autonomous Database for Transaction Processing and Mixed Workloads databases.īastions are essential in tenancies with stricter resource controls. For example, you can use the Remoteĭesktop Protocol (RDP) to connect to a Windows host, or use Oracle Net Services to connect to a database. Users can interact with the target resource by using any software or protocol supported by SSH.
