  • Patent number: 9645861
    Abstract: A method for managing application containers, comprising: assigning a first application to a master container in a memory of a system; assigning a second application to a slave container in the memory; using a processor, assigning the master and slave containers to a container group by: delegating access to container meta-data of the slave container by a container run-time of the slave container or by the first application to a container meta-data accessor of the master container via a class loader of the master container; and, delegating interaction between the container run-time of the slave container and a container management channel of the slave container to a container management channel of the master container via the class loader of the master container; and, accessing the first and second applications via the container group.

  • Publication number: 20140359777
    Abstract: A mobile device management server and method are provided for determining the security risk for deployed mobile devices. The mobile device management server receives risk measurements from mobile devices that are used to calculate a risk score based on rules. The risk score can also be adjusted by correlating the received risk measurements with past security breaches or typical usage measurements. The calculated risk score is compared to a one or more thresholds to determine whether to take a protective action that is associated with exceeding a threshold.
