PORTKnockOut: Data Exfiltration via Port Knocking over UDP Analyst Paper
by Matthew Lichtenberger - September 29, 2016
Data Exfiltration is arguably the most important target for a security researcher to identify. The seemingly endless breaches of major corporations are done via channels of various stealth, and an endless array of methods exist to communicate the data to remote endpoints while bypassing Intrusion Detection Systems, Intrusion Prevention Systems, firewalls, and proxies. This research examines a novel way to perform this data exfiltration, utilizing port knocking over User Datagram Protocol. It focuses specifically on the ease at which this can be done, the relatively low signal to noise ratio of the resultant traffic, and the plausible deniability of receiving the exfiltration data. Particular attention is spent on an implemented Proof of Concept, while the complete source code may be found in the Appendix.

Measuring Psychological Variables of Control In Information Security by Josh More - January 12, 2011
Perceived Control is a core construct used in the psychology field that can be considered an aspect of empowerment (Eklund, & Backstrom, 2006). Effectively, it is a measure of how much control people feel that they have, as opposed to the amount of Actual Control that they may have. It is often paired against constructs such as Vicarious Control and Vicarious Perceived Control, which measure the amount of control that outside entities have over the subject. Often, these are variables measured in the psychology/health field. For example, in the world of medicine, when patients report a lack of perceived control over controllable illnesses such as diabetes (Helgeson, & Franzen, 1997), breast cancer (Helgeson, 1992) and heart disease (Helgeson, 1992), they often do more poorly than patients who feel that they have a greater sense of control over their illness. There is also evidence that students with high perceived control do substantially better academically than those with low, though this seems to also link with emotions surrounding the tasks at hand (Ruthig, Perry, Hladkyj, Hall, & Pekrun, 2008). In short, people who are interested in and excited by what they are doing tend to perform better.
