Cloud Computing Risks And Risk Management, Anthony Hopkins
Cloud Computing Risks And Risk Management, Anthony Hopkins
Senior Seminars
Cloud computing is an emerging technology that is becoming more and more popular every year. With the many benefits that the cloud provides it is hard for corporations not to integrate it into their business operations. With the increase usage in cloud computing substantial risks and concerns are beginning to surface. External data breaches, malicious insiders, outages, vendor lock-in, and insufficient due diligence are a couple of the major risks and concerns that need to be on the minds of the customer and the cloud service provider. The customer and the provider needs to know how to mitigate the risks …
Impact Of The Shodan Computer Search Engine On Internet-Facing Industrial Control System Devices, Roland C. Bodenheim
Impact Of The Shodan Computer Search Engine On Internet-Facing Industrial Control System Devices, Roland C. Bodenheim
Theses and Dissertations
The Shodan computer search engine crawls the Internet attempting to identify any connected device. Using Shodan, researchers identified thousands of Internet-facing devices associated with industrial controls systems (ICS). This research examines the impact of Shodan on ICS security, evaluating Shodan's ability to identify Internet-connected ICS devices and assess if targeted attacks occur as a result of Shodan identification. In addition, this research evaluates the ability to limit device exposure to Shodan through service banner manipulation. Shodan's impact was evaluated by deploying four high-interaction, unsolicited honeypots over a 55 day period, each configured to represent Allen-Bradley programmable logic controllers (PLC). All …
Directed Graph Cryptosystems, Kurt Anson Boberg
Directed Graph Cryptosystems, Kurt Anson Boberg
All Master's Theses
Cryptography is a necessary tool for secrecy in our increasingly connected and data-driven world. As advances are made in both mathematics and computer hardware design, existing cryptosystems must be improved or replaced to maintain privacy of sensitive data. In this paper we propose a novel cryptosystem based upon an algorithmic traversal of a directed graph (digraph). The system is resistant to the most common attacks on stream-type ciphers that do not use known-plaintext attacks. However, given a length n, the minimum number of vertices a digraph must contain to guarantee a cycle of at least n length is unknown, making …
