Abstract: A segmentation server updates enforcement of a segmentation policy based on detection of core services. The segmentation server obtains characteristics of workloads and identifies workloads that provide core services using port matching, supervised learning based classification, semi supervised learning based classification, or a combination thereof. The segmentations server applies labels to workloads identified as core service providers indicative of the detection. Rules of the segmentation are distributed to enforcement modules based on the label sets of associated workloads to enable the enforcement modules to enforce the segmentation policy. Detection of core services reduces the likelihood of administrator inadvertently enforcing a policy that blocks essential core services.

Abstract: A secure private network connectivity system (SNCS) within a cloud service provider infrastructure (CSPI) is described that provides secure private network connectivity between external resources residing in a customer's on-premise environment and the customer's resources residing in the cloud. Secure access to an external resource is enabled by the SNCS by creating an external resource representation (i.e., a computing instance) for the external resource in the customer's virtual cloud network (VCN) in the cloud and creating a virtual network interface card for the external resource representation. Using the SNCS, the customer can securely access the external resource residing in their on-premise network from within their VCN by connecting to the virtual IP address assigned to the VNIC without requiring to set up elaborate site-to-site networking, without making changes to their on-premise routing configuration or without making any changes to the configuration of the external resource.
