Patent attributes
Various technologies and techniques are disclosed that provide a centralized model to assign, monitor, and manage security on home electronic devices. A three-dimensional security matrix uses a role-based model that allows users to map security into groupings. Users can be assigned security levels based on application role (what activity is involved), user role (what each family member or guest is allowed to do), and device role (what this device is allowed to do while preserving system integrity). An authorization service determines whether a particular activity requested by the user should be granted or denied based upon whether the user has authorization to access the particular activity and whether the particular device can support the particular activity without comprising the security of the network.
