Secure servers

Type	Description
OpcAccessControlEntry	Represents the access control settings of a single OpcPrincipal in an OpcAccessControlList: the operations allowed or denied and the endpoints enabled or disabled for the principal.
OpcAccessControlList	Provides the abstract base class of the access control lists of an OpcServerSecurity, which authenticate the identity tokens of one OpcAccessControlTokenType and maintain one OpcAccessControlEntry per OpcPrincipal.
OpcAccessControlMode	Specifies how an OpcAccessControlEntry evaluates an operation which has neither been allowed nor denied explicitly and an endpoint which has neither been enabled nor disabled explicitly.
OpcAccessControlRole	Represents a single access control role OpcPrincipal instances can be a member of.
OpcAccessControlTokenType	Specifies the type of the user identity tokens an access control list of a server is responsible for.
OpcAnonymousAcl	Represents the access control list of an OpcServerSecurity which authenticates anonymous identity tokens.
OpcAuthenticationLimits	Provides authentication options used by a server application instance to control the limits of authentications between the opponent applications.
OpcCertificateAcl	Represents the access control list of an OpcServerSecurity which authenticates X.509 certificate identity tokens using the OpcCertificateIdentity instances of its entries.
OpcCertificateChangedEventArgs	Provides the event data for 'CertificateChanged' events.
OpcCertificateIdentity	Represents the identity of a user which is described by a certificate.
OpcCertificateIdentityTokenInfo	Describes an identity a client stated by a certificate.
OpcCertificateManager	Provides a set of static (Shared in Visual Basic) methods to manage certificates.
OpcCertificateRequestedEventArgs	Provides the event data for the CertificateRequested event.
OpcCertificateSettings	Defines the setup of an application instance certificate.
OpcCertificateStoreInfo	Represents a certificate store, which provides access to the certificates stored at its Path.
OpcCertificateStores	Provides access to the set of OPC UA predefined certificate stores typically used by an OPC UA application to maintain its certificates.
OpcCertificateValidationFailedEventArgs	Provides the event data for 'CertificateValidationFailed' events.
OpcCertificateValidationRules	Defines the different validation rules which can be additionally applied to the default validation rules of a certificate validation.
OpcEndpointIdentity	Represents the identity of an endpoint, which consists of its URL and its security policy.
OpcIdentityToken	Represents the user identity token a client passes to the server to identify the user of a session.
OpcIdentityTokenInfo	Describes the identity a client stated, without any secret it stated along with it.
OpcOperationLimits	Provides operation options used by a server application instance to control the limits of operation between the opponent applications.
OpcOperationType	Represents the type of an operation which an OpcAccessControlEntry allows or denies.
OpcPrincipal	Represents a user of the server by its OpcIdentity, to which the entries of the access control lists and the access control roles apply.
OpcRequestType	Specifies the type of a request a client sends to the server, named after the service the request calls.
OpcRequestValidatingEventArgs	Provides the event data for the RequestValidating event.
OpcSecurityPolicy	Describes the configuration used to secure the message exchange.
OpcServer	Represents an OPC UA server which provides the address space defined by its NodeManagers to its clients.
OpcServerBinding	Provides a set of options used when binding a server instance to a network interface.
OpcServerIdentity	Represents the identity of a user of the server, which is identified by a user name and a password.
OpcServerSecurity	Provides the security options of a server, including the access control lists which authenticate the identity tokens of the clients and determine the operations and endpoints available to them.
OpcServerSecurityRoles	Provides the default OpcAccessControlRole instances usually known to the OpcServer.
OpcSession	Represents a session which a client has created on the server.
OpcSessionActivationFailedEventArgs	Provides the data of the SessionActivationFailed event.
OpcSessionActivationFailedEventHandler	Represents the method that handles the SessionActivationFailed event.
OpcTransport	Provides transport options used by an application instance to control the behavior of the operation, communication and data flow between the opponent applications.
OpcUserIdentity	Represents the identity of a user described by an OPC UA user identity token (e.g. an anonymous user, a user name or a certificate).
OpcUserNameAcl	Represents the access control list of an OpcServerSecurity which authenticates user name identity tokens using the OpcServerIdentity instances of its entries.
OpcUserNameIdentityToken	Represents the user identity token of a client which identifies a user using a user name and a password.
OpcUserNameIdentityTokenInfo	Describes an identity a client stated by a user name, without its password.
