A method of management of concurrent sessions within a networked electronic system across multiple servers generally comprises defining a model of the system to be managed, and then defining policies, which policies are applicable to components of the model. Then, system components are modelled as entities in the model with hierarchical relationships between the entities. The entities each comprise a single physical or non-physical object in the system. The model is split into parts such that policy information for a given entity is held on a nominated server, with other servers being informed of where to find the policy information, determination of which policies to apply to a given request being made by a policy checker, which policies are then executed.
