Abstract: Methods and systems for managing data communications are described. The method includes receiving a data communication; analyzing the data communication to determine a particular type of sender or recipient activity associated with the data communication based at least in part on an application of a plurality of tests to the data communication; assigning a total risk level to the data communication based at least in part on one or more risks associated with the particular type of sender or recipient activity and a tolerance for each of the one or more risks; comparing the total risk level assigned to the data communication with a maximum total acceptable level of risk; and allowing the data communication to be delivered to a recipient in response to the comparison indicating that the total risk level assigned to the data communication does not exceed the maximum total acceptable level of risk.

Abstract: Methods and systems for operation upon one or more data processors for assigning reputation to web-based entities based upon previously collected data.

Abstract: Methods and systems for adjusting control settings associated with filtering or classifying communications to a computer or a network. The adjustment of the control settings can include adjustment of policy and/or security settings associated with the computer or network. Ranges associated with the control settings can also be provided in some implementations.

Abstract: A network security modeling system which simulates a network and analyzes security vulnerabilities of the network. The system includes a simulator which includes a network vulnerabilities database and a network configuration module having network configuration data. The simulator determines vulnerabilities of the simulated network based on the network configuration data and the vulnerabilities database.
