TSYS School Computer Scientists Utilize Network Traffic Distribution to Detect Stepping-Stone Intrusion

A new study by TSYS School computer scientists Jianhua Yang and Lixin Wang explores the use of network traffic distribution to detect stepping-stone intrusion. Appearing in the latest issue of Electronics, the study acknowledges that over the past three decades, stepping-stone intrusion has become a professional and primary way used by intruders to launch their attacks given that it offers protection via a long transmission control protocol connection chain. According to Yang, "Many different algorithms have been proposed to detect stepping-stone intrusion since 1995. But most algorithms cannot resist intruders’ session manipulation. In this paper, we propose a novel approach using the distribution of round-trip time (RTT) of network traffic to detect stepping-stone intrusion." Among the advantages of the approach developed by Yang and Wang are (1) its ability to bring down false-positive detection errors since it belongs to a network-based detection method, (2) its ability to function as intended without having to collect packets from the beginning to the end of establishing a connection chain, (3) its ability to resist intruders’ chaff-perturbation manipulation, and (4) it achievement of a high detection rate.

Turner College Grad Publishes Academic Study on Corporate Culture and Strategy

Former Turner College student Tamara Todorova , now an associate professor of economics at American University in Bulgaria (AUB), recently published a study on corporate culture and strategy. Todorova earned an MBA from the Turner College in 1996 and then went on to earn a doctorate in international economics from the University of Economics - Varna in 2001. She has been on the faculty at AUB since August of 2000. Todorova's study, which appears in the current issue of the International Journal of Business Performance Management , investigates how corporate culture helps to economize on the transaction costs of internal organization. As she explains, the dimensions of corporate culture that assist in this task include increasing trust and reducing intrafirm opportunism. Todorova's study demonstrates that setting common goals and a common direction reduces the sizeable costs of internal organization. Tamara's prior research appears in Economics of Transition , International

Hammer joins Turner College Finance Faculty

The Turner College's Department of Accounting and Finance welcomes Melissa Ingle Hammer , who joins the group as an adjunct faculty in finance. Hammer graduated from the Turner College in 2005, after earning a BBA in finance. She later went on to earn an MBA from Auburn University, a Specialist Certificate in Conduct Risk from the University of Manchester, a Certificate in Team Culture from the University of Pennsylvania, and a Certificate in Executive Presence from Cornell University. Hammer is the SVP of Fair Lending Product Management with RiskExec at Asurity. She previously worked as Compliance Manager of Fair Lending at Synovus, a senior regulatory consultant with Wolters Kluwer, and as VP of Compliance at TD. This semester Hammer will be teaching FINC 3135, Financial Institutions and Technologies. Turner Business welcomes Melissa and wishes her a great first semester in the Turner College.

TSYS School, Jianhua Yang, Lixin Wang Each among Top Five in the World

New research by computer scientists in the School of Information Technology at Universiti Utara Malaysia that ranks institutions and individuals on the basis of scholarship in the area of stepping-stone attacks heaps praise on the Turner College’s TSYS School of Computer Science and two of its faculty – Jianhua Yang and Lixin Wang . The article, published in the April 2023 issue of the International Journal of Research in Engineering and Science , provides a bibliometric analysis of both publication and citation data from 2000 to September of 2022 related to research on stepping-stone intrusion. Among several results, it reports that Columbus State University ranks second worldwide, trailing only the University of Houston, using total publications on the subject as the basis of comparison. A number of other U.S. institutions appear in the top 10, including third-ranked North Carolina State University, fourth-ranked University of Illinois, sixth-ranked Iowa State University, eig
