A System For Detecting Malicious Insider Data Theft In Iaas Cloud Environments, Jason Nikolai, Yong Wang
Faculty Research & Publications
The Cloud Security Alliance lists data theft and insider attacks as critical threats to cloud security. Our work puts forth an approach using a train, monitor, detect pattern which leverages a stateful rule based k-nearest neighbors anomaly detection technique and system state data to detect inside attacker data theft on Infrastructure as a Service (IaaS) nodes. We posit, instantiate, and demonstrate our approach using the Eucalyptus cloud computing infrastructure where we observe a 100 percent detection rate for abnormal login events and data copies to outside systems.

Android forensics has evolved over time offering significant opportunities and exciting challenges. On one hand, being an open source platform Android is giving developers the freedom to contribute to the rapid growth of the Android market whereas on the other hand Android users may not be aware of the security and privacy implications of installing these applications on their phones. Users may assume that a password-locked device protects their personal information, but applications may retain private information on devices, in ways that users might not anticipate. In this thesis we will be concentrating on one such application called 'WhatsApp', a …
Covert Shells, John Christian Smith
Covert Shells, John Christian Smith
John Christian Smith
The potential for covert communications exist anywhere that legitimate communication channels are in use. In order to maintain control of the channel once exploited, the insertion of a backdoor Trojan horse server, to be used with a client that provides shell access, is often a necessary prerequisite to establishing and using a covert channel long term.
We discuss covert channel communications methods ranging from embedded channels to disguised protocols. What follows is a review of available covert shell tools. The underground, historical evolution of covert shells is reviewed, focusing on selected, available tools, which range from simple encapsulation methods to …
