Abstract: The disclosed embodiments provide a system that secures a network. During operation, the system obtains a request for a resource from a client connected to the network. Next, the system uses a domain name from the request to obtain one or more properties associated with the domain name and assesses a level of risk associated with the domain name based on the one or more properties. Finally, the system processes the request based on the assessed level of risk.

Abstract: Embodiments of a computer system, a method and a computer-program product (e.g., software) for use with the computer system are described. These embodiments may be used to assist users while they are filling in forms. In particular, based at least in part on a current location of a user (such as a location of a portable electronic device associated with the user), an association with location and non-location information for an entity may be identified. For example, a predetermined relationship between the user's current location and the location of the entity may be accessed. Alternatively, a relationship between the user's current location and the location of the entity may be determined, for example, based at least in part on proximity. This identified location and/or non-location information for the entity may be used to fill in one or more fields in a form associated with an application.

Abstract: Embodiments of a computer system, a method, and a computer-program product (e.g., software) for use with the computer system are described. These embodiments may be used to customize displayed content in a document, such as a web page or a user interface in a software application. In particular, by monitoring user activities while one or more users view the document during multiple sessions, the computer system can identify the most relevant content at a particular time. Then, the computer system selectively modifies the displayed content in the document based on the monitored user activity. For example, the computer system may selectively filter the content in the document so that a subset of the content is displayed. Moreover, the displayed content may be dynamically revised based on subsequent user actions.

Abstract: One embodiment of the present invention provides a system that facilitates defining relationships between tags. During operation, the system receives a user-specified tag that describes a data item. Next, the system displays this tag to a user via a user interface that gives the user the option to suggest additional relationships for the tag. Based on user input, the system may define a relationships between the two tags, thereby facilitating the definition of a set of related tags for an organization.
