Investigative response modeling and predictive data collection

While most enterprise computing environments are proactively monitored for threats and security violations using automated detection engines, the ability to validate reported events as true incidents still requires a non-trivial amount of time and information gathering as well as investment in staffing and training of personnel. To improve an organization´s overall reactive security posture and reduce some of the associated costs we propose an investigation model supported by predictive, automated data collection and guided presentation of the resulting information. By modeling the investigative goals and requirements for each event type, this approach can automate proactive data collection actions wherever possible thus reducing the investigation time as well as providing a consistent framework for the monitoring staff. By providing the goals of the alert validation process the framework also reduces the minimum skill required of monitoring staff. Furthermore, the collected information is presented in a formatted manner with documented requirements for validation therefore guiding the analyst to the appropriate conclusion. By following this method, false positive alerts are more quickly pared down allowing for better utilization of skilled resources by focusing efforts on only those alerts validated as genuine.
