A systems analysis of insider data exfiltration : a decentralized framework for disincentivizing and auditing data exfiltration
It has become common place to hear of data breaches. Typically, we hear of external hackers as the perpetrators, however, the reality is there is a high frequency of threats from insiders within an organization and that the cost and challenge in detecting these threats is considerable. The issue …

Monitoring and Preventing Data Exfiltration in Android-hosted Unmanned Aircraft System Applications
… nature which puts the user at the risk of data exfiltration. As most Android-hosted UAS applications are proprietary software, their source code cannot be studied or modified. This thesis discusses an external monitoring system which is devised in order to assess the threat of data exfiltration. …

INVESTIGATING DRONES USING OPEN-SOURCE FORENSIC SOFTWARE
… components because of the potential of exfiltration of sensitive data to foreign nations. Drone sales and usage are growing steadily, but it is difficult to do forensic investigation of drones to determine what they are doing. This research examined storage of three drones using …

Rainfall-runoff control: variably saturated transport for an infiltration system controlling water quality and quantity
… quality and quantity functions of a partial exfiltration reactor (PER) utilizing Fe-coated-sand and porous pavement (CPP) is examined specifically across three representative rainfall-runoff events. Total concentrations and mass for metals (Zn, Pb, Cu and Cd), suspended solids, and Chemical …

eMicro: Real-Time Multi-Hop Access Control for Microservices with eBPF
… systems exposed to unauthorized access and data exfiltration. In this thesis, we present eMicro, a path-aware defense system for microservices that prevents such attacks while remaining efficient and deployable. eMicro enforces real-time multi-hop access control through three key techniques: (1) …

Threat Detection in Program Execution and Data Movement: Theory and Practice
… by other malicious activities such as data exfiltration. The integration of primitive attacks constructs comprehensive attack vectors and forms advanced persistent threats. Along with the rapid development of defense mechanisms, program attacks and data leak threats survive and evolve. …

Digital provenance - models, systems, and applications
… we devise a mechanism for detecting data exfiltration attack in a file system. We then move to the direction of secure provenance communication in streaming environment and propose two secure provenance schemes focusing on WSNs. The basic provenance scheme is extended in order to detect …

Moisture occurrence in roof assemblies containing moisture storing insulation and its impact on the durability of building envelope
… and retrofit construction. Moisture deposited by exfiltration and adsorbed within the envelope reduces the thermal performance of the envelope and favors fungus growth leading to deterioration of the materials and contamination of the indoor air. Roof assemblies thus insulated are particularly …
