Network covert channels on the Android platform
Network covert channels are used to exfiltrate information from a secured environment in a way that is extremely difficult to detect or prevent. These secret channels have been identified as an important security threat to governments and the private sector, and several research efforts have …

Real-Time Detection of Storage Covert Channels
Covert channnels are a class of techniques for hiding the presence of communication between parties. In the context of cybersecurity, covert channels can be used by attackers to evade detection and to exfiltrate sensitive data. In so doing, they create a need for effective detection techniques for …

Sneak-peek: high speed covert channels in data center networks
… In this thesis, we present a novel network-based covert channel that can arise in the context of shared network resources in data-center environments even in the presence of network monitors regulating flow destinations with NAC policies and VLAN-based isolation mechanisms. Through a series of …

Synthetic steganography: Methods for generating and detecting covert channels in generated media
… steganography: generating and detecting covert channels in generated media. We start by demonstrating how to generate synthetic time series data that not only mimic an authentic source of the data, but also hide data at any of several different locations in the reversible generation …

Network-aware Active Wardens in IPv6
… might have a legitimate reason to communicate covertly. And at the same time, the use of digital communications for business, military, and also criminal purposes gives equally compelling reasons for monitoring them thoroughly. Covert channels are communication mechanisms that were never …

Leveraging concurrency for performance and security
… enable the detection of otherwise undetectable covert channel attacks using two techniques -- ReplayConfusion and ReplayEndurance. %These techniques allow the detection of covert channels which flow across the Last Level Cache or across the speculative execution boundary. Covert channels encode …

Application Adaptive Bandwidth Management Using Real-Time Network Monitoring.
… competing for a network’s crucial bandwidth, covert channels of communication via non-standard traffic on well-known ports, and coordinated Denial of Service attacks. The study undertaken here explored the classification, analysis and management of the network traffic on the basis of ports and …

Decentralized information flow control for databases
… in a database and proposes new ways to address covert channels. Finally, the IFDB implementation and case studies with real applications demonstrate that database support for DIFC improves security, is easy for developers to use, and has good performance.

Detection of data leakage and disruption of covert timing channel in secure drone communication using machine and deep learning
… examines the detectability and disruptability of covert timing channel traffic in secure drones. The investigation aims to ascertain the effects of multiple interarrival times, distances ranging from 1 to 330 feet, various detection algorithms, and stream sizes between 32-bit and 256-bits on the …
