To enhance the effectiveness of health care, many medical institutions have started transitioning to electronic health and medical records and sharing these records between institutions. The large amount of complex and diverse data makes it difficult to identify and track relationships and trends, such as disease outbreaks, from the data points. INFERD: Information Fusion Engine for Real-Time Decision-Making...
Mission impact assessment for computer networks has become increasingly important as the prevalent cyber assets support more and more mission critical infrastructure for daily operations as well as emergency responses. Existing work lacks comprehensive and systematic treatment and thus may not be able to provide timely assessment. Evolving from a general graphical representation of cyber assets, this...
In cyberspace, attackers are becoming increasingly agile, coordinated, and advanced. In response, defenders have deployed cyber sensors in order to gain visibility into both network and host activities. However, the data generated by these sensors must be correlated to identify individual attacks. This is currently a highly manual process. Unfortunately, this approach does not scale as the number...
Intelligence collection, while critical in mission planning, lacks systematic means to quantify its value for optimal prioritization. This work proposes a framework that starts with analyzing the plausible impacts imposed on assets and mission due to predicted adversary activities. The candidate collection requirements, derived from plausible futures, are evaluated for their benefits to mitigate potential...
With expanding network infrastructures, increasing vulnerabilities and uncertain malicious activities, cyber security research has begun to provide situation assessment beyond Intrusion Detection Systems (IDSs). A key goal of cyber situation assessment is to efficiently and effectively project the likely future targets of ongoing multistage attacks. This work presents two ensemble techniques that...
The use of computer networks has become a necessity for government, industry, and personal businesses. Protection and defense against cyber attacks on computer networks, however, are becoming inadequate as attackers become more sophisticated and as the networks and systems become more complex. Drawing analogies from other application domains, this paper introduces information fusion to provide situation...
