Abstract: Techniques for selectively filtering data are discussed herein. For example, a request to include data in an electronic message or a request to copy the data to a portable storage device may be received. If the data is sensitive data, the techniques may determine a software application that was opened or closed prior to receiving the request, or information that was accessed prior to receiving the request. The techniques may determine if including the data in the electronic message or copying the data to the portable storage device poses a security risk. If a security risk is identified, a task may be performed, such as alerting a network administrator, providing a notification to a user regarding the data, or preventing copying or transmission of the data.

Abstract: A software-based security agent that hooks into the operating system of a computer device in order to continuously audit the behavior and conduct of the end user of the computer device. The detected actions of the end user can be stored in a queue or log file that can be continuously monitored to detect patterns of behavior that may constitute a policy violation and/or security risk. When a pattern of behavior that may constitute a policy violation and/or security risk is detected, an event may be triggered. A frequency vector string matching algorithm also is disclosed. The frequency vector string matching algorithm may be used to detect the presence or partial presence of subject strings within a target string of alphanumeric characters. The frequency vector string matching algorithm could be used to detect typos in stored computer records or to search for records based on partial information.
