A method and system for controlling access to a service by increasing security and/or authentication is described. A security controller comprises: a processor that receives event data and is connected to a state data store comprising state data indicating a status of a first device in a computing system. The state data comprises a proximity status of the first device relative to at least one other device in the computing system and a security status of the first device relative to at least one other device in said computing system. A policy data store stores a policy determining the required proximity status and security status of the first device. The processor is configured to read the event data, state data and the policy; determine whether the proximity status of the first device meets the required proximity status defined in the policy; determine whether the security status of the first device meets the required security status defined in the policy and output action data via an action output if both said determining steps are complied with. |
