A security function is provided by an intermediate device located between hosts and devices requesting for access to the hosts in a computerized network. The intermediate device receives a request for access to a host, and obtains at least one authenticator for use in the requested access to the host. The intermediate device then monitors for communications that use the at least one authenticator.

Accessing hosts in a computer network

Methods and apparatuses for authentication in a computer network system based on security credentials issued for client hosts by a remote security authority are disclosed. In response to detection that a client host is prevented from obtaining security credentials from the remote security authority for use in accessing a target host, the client host can obtain an emergency security credential from a storage of emergency security credentials. The emergency security credential with an error state indication can be send from the client host to the target host for use in the authentication.

Authentication in a computer network system

A virtual smart card entity enabling a data processing apparatus to request for access to at least one service provider host in the computer network is disclosed. A credential management server provides credential information associated with the virtual smart card entity to the data processing apparatus where after the virtual smart card entity is configured according to the credential information. The data processing apparatus can then send a request for access to at least one service provider host using the configured virtual smart card entity.

Access security in computer networks

The disclosure relates to apparatuses and methods for a computer network comprising hosts accessible by directory users whose user identity information is maintained in a user information directory. The apparatus comprises at least one processor, and at least one memory for storing instructions that, when executed, cause the apparatus to manage information of configurations for attribute based filtering of access requests by the directory users for a plurality of hosts and separately from the user information directory.

Access control in a computer system

Apparatuses and methods for authenticating a user to a host by an agent are disclosed. In the method the agent receives a connection request to the host from the user. In response to the received connection request, the agent determines an ephemeral authenticator, and acquires using the ephemeral authenticator a second authenticator. The second authenticator is based at least in part on use of the ephemeral authenticator. The agent then authenticates the user to the host using the second authenticator.

Authentication of users in a computer network

The disclosure relates to apparatuses and methods for managing authenticator information in a computerized system. An access request to a host comprising an authenticator is processed to cause searching in an authenticator management host for information corresponding to the authenticator and searching in a directory internal to the host for information corresponding to the authenticator. Modification of information corresponding to the authenticator can then be provided based on the searching.

Management of authenticator information in a computer system

A hybrid computer network environment can include a first type of hosts and a second type of hosts. An apparatus adapted to receive requests for access to hosts obtains authenticators for accessing the hosts. The apparatus can further determine the type of the hosts and process the requests for access using a first type of authenticator for access to the first type of hosts and a second type of authenticators for access to the second type of hosts.

Accessing hosts in a hybrid computer network

A method, device, system and computer program for providing a transport distribution scheme for a security protocol are disclosed. A first packet data connection is established to a remote node for transmitting packet data over a network with a security protocol. An authentication procedure is performed with the remote node via the first packet data connection for establishing a security protocol session with the remote node. At least one security parameter is negotiated with the remote node for transmitting packets through the first packet data connection. A second packet data connection is established to the remote node, and at least one security parameter is negotiated with the remote node for use with the second packet data connection. The first and second packet data connections are handled as packet data subconnections associated with the security protocol session.
