Abstract: Management instructions for a particular managed server within an administrative domain are generated according to an administrative domain-wide management policy that comprises a set of one or more rules. A bound service executed by the particular managed server is identified. The bound service has different high-level characteristics from other services executed by the particular managed server. Relevant rules within the set of rules are determined that are relevant to the bound service. A set of relevant managed servers that are relevant to the bound service are selected by identifying managed servers of the plurality that are referenced by the relevant rules. Function-level instructions are generated that regulate communication between the bound service and the set of relevant managed servers based on the relevant rules. The function-level instructions are sent to the particular managed server for use in configuring a management module to implement the administrative domain-wide management policy.

Abstract: Management instructions for a managed servers are updated according to a set of rules included in management policy. A global manager computer receives information describing a change in a bound service executed by the particular managed server. The global manager generates an updated description of the particular managed server is generated by modifying an initial description of the particular managed server according to the received information describing the change in the bound service. The global manager determines currently relevant rules for the particular managed server. If the currently-relevant rules differ from previously-relevant rules, the global manager determines a rule is that should be added. The global manager generates a function-level instruction including a reference to an authorized actor-set of actors permitted to communicate with the bound service. The global manager configures the particular managed server to enforce the function-level instruction.

Abstract: A segmentation server defines a segmentation policy and distributes the segmentation policy to be enforced by a plurality of operating system (OS) instances. The segmentation policy includes rules controlling which workloads executing on the OS instances can communicate with other workloads and controlling how the workloads may communicate. When a connection between two OS instances is requested, each OS instance provides an identity and a cryptographic proof of the identity. The OS instances each authenticate the identity received from the other OS instance, and once authenticated, determines based on the authenticated identities if the rules permit the communication. If the rules permit the communication, the OS instances obtain session parameters that enable the OS instances to validate integrity of the messages communicated between the workloads and optionally encrypt the messages.

Abstract: An access control rule authorizing communication between a plurality of managed servers within an administrative domain is determined. Communication information describing past communication between the plurality of managed servers is obtained. A subset of managed servers from the plurality of managed servers is identified by grouping the plurality of managed servers based on the obtained communication information. A group-level label set is determined to associate with the subset of managed servers. Role labels are determined for managed servers in the subset of managed servers. A managed server is associated with one role label. Based on the group-level label set and the role labels, an access control rule is generated authorizing communication between a first managed server of the subset of managed servers and a second managed server. The access control rule is stored as part of an administrative domain-wide management policy.

Abstract: A server is paired. A pairing request that includes a pairing key is received from an unpaired server. A determination is made regarding whether to approve or reject the pairing request. Making the determination comprises attempting to validate the pairing key in the pairing request. Responsive to determining to approve the pairing request: the unpaired server is notified that the unpaired server is now a managed server; a description of the managed server is generated, wherein the managed server description includes a set of one or more labels that describe the managed server; management instructions are generated for the managed server based on the managed server description and based on an administrative domain-wide management policy that includes a rule that refers to managed servers using a label; and the management instructions are sent to the managed server.

Abstract: A change to a state of a particular managed server within an administrative domain is processed. The administrative domain includes a plurality of managed servers that use management instructions to configure management modules so that the configured management modules implement an administrative domain-wide management policy that comprises a set of one or more rules. A first description of the particular managed server is modified to indicate the particular managed server's changed state, thereby specifying a second description of the particular managed server. The unmodified first description is compared to the second description, thereby specifying a description change. A determination is made, based on the description change, regarding whether to update management instructions previously sent to the particular managed server.

Abstract: A global manager computer generates management instructions for a particular managed server within an administrative domain according to a set of rules. A global manager computer identifies a traffic midpoint device through which the provider managed server provides a service to a user device. The global manager determines a relevant rule from the set of rules that is applicable to communication between the provider managed server and the user device and generates a backend rule that is applicable to communication between the provider managed server and the traffic midpoint device. The global managed generates a backend function-level instruction including a reference to an actor-set authorized to communicate with the provider managed server to use the service. The global manager sends the backend function-level instruction to the provider managed server to configure the provider managed server to enforce the backend rule on communication with the actor-set including the traffic midpoint device.

Abstract: A managed server (MS) within an administrative domain is quarantined. The administrative domain includes multiple MSs that use management instructions to configure management modules so that the configured management modules implement an administrative domain-wide management policy that comprises a set of one or more rules. The quarantined MS is isolated from other MSs. A description of the MS is modified to indicate that the MS is quarantined, thereby specifying a description of the quarantined MS. Cached actor-sets are updated to indicate the quarantined MS's changed state, thereby specifying updated actor-sets. A determination is made regarding which updated actor-sets are relevant to an other MS, thereby specifying currently-relevant updated actor-sets. A determination is made regarding whether the currently-relevant updated actor-sets differ from actor-sets previously sent to the other MS.

Abstract: A system enforces administrative domain wide policies specified using labels that describe characteristics of servers or services. A label comprises a label value describing a characteristic of one or more computing devices for a label dimension. The system infers label values for devices using features describing characteristics of the computing devices, for example, hardware characteristics, software characteristics, or connectivity characteristics. The system obtains communication information indicating the destination, source, volume, and duration of network traffic between computing devices. The system identifies providers of services and consumers of services based on the communication information. The system generates rules for regulating communications between computing devices and enforces the rules.

Abstract: State information is received from a server indicating an identity of a user logged into the server. An administrative domain wide policy is determined that specifies a relationship between user a group and services or servers accessible to users belonging to the user group. Relevant servers are sent updated management instructions corresponding to rules of the administrative domain wide policy. Such rules provide access to a service or server to users belonging to user groups related to the service. As a result, the servers allow communications that provide access to users based on the specified relationships.
