Abstract: A method is provided for authorizing an authenticated user into a teleconference session as a participant that avoids some of the costs and disadvantages of doing so in the prior art. The authorization is a combination of the enterprise user's authentication at work and cryptographic authorization to the teleconference system by the inviter. When a user goes to work and connects with his or her office computer to the network of the user's employer, a secure single sign-on (SSO) access control procedure is executed. In a secure single sign-on (SSO) access control procedure, the user submits authentication information, such as a user name and password, to an identity provider and receives back a credential token when the identity provider determines that the user name/password pair is valid. The credential token is saved on the user's computer and used for further authentication.

Abstract: A method is provided in which a permission for running a system software instance alongside another system software instance is issued on the basis of a first policy rule concerning the operation of a first software application and a second policy rule concerning the execution of second software application.

Abstract: Software interoperability is determined in a system comprising components capable of operating using different combinations of software applications. Training data is received for the system indicating changes to a system metric as a function of the different combinations of software applications. From the training data, it is determined which of the components directly or through interactions with other components have a statistically significant effect on the system metric when changing between the different combinations of software applications. From the training data, a software interoperability decision tree for the system is formulated. The software interoperability decision tree uses those components determined to have a statistically significant effect on the system metric as decision tree attributes.
