Abstract: An information processing system includes an event analyzer that detects an occurrence of an event on a basis of data measured by a predetermined sensor; a storage that stores a security policy that defines a user attribute allowed to access to each type of the event; and an access controller that controls whether or not an access from a user to data on which the event is occurring is permitted on a basis of the security policy.
