  • Network security modeling system and method
    Patent number: 7996201
    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.
    Type: Grant

  • Security framework for dynamically wrapping software applications executing in a computing system
    Patent number: 6658571
    Abstract: A security framework for wrapping standard, commercially-available software applications in order to limit the amount of potential damage that a successful attacker or corrupt program can cause. The security framework includes a security master that coordinates installation and removal of kernel-based security modules and that provides a means for managing these modules. The security module are loadable kernel modules that include security information for enforcing application-specific or resource-specific policies. The security module are easy to install and require no modification to the existing operating system or to the software applications that they are monitoring. The security framework has a number of potential applications, including protecting a computing system from malicious software downloaded via a web browser, for wrapping web servers and firewalls in order to limit possible compromise and for replicating file operations.
