As TSYS School computer scientists Jianhua Yang and Lixin Wang, along with their student Maochang Qin, explain in a new study, hackers usually send attacking commands through compromised hosts, called stepping-stones, for
the purpose of decreasing the chance of being discovered. An effective approach for stepping-stone
intrusion detection is to estimate the length of a connection chain. This type of detection
method is referred to as the network-based stepping-stone intrusion detection. According to Yang, "All of the existing network-based stepping-stone intrusion detection approaches use
the distribution of packet round-trip times to estimate the length of a connection chain. Our study explores a novel approach – Fast Fourier Transformation – to analyze the
distribution of packet round-trip times." To do so, Yang and his colleagues first capture network packets from different stepping-stones in a
connection chain, after which they identify and match the Send and Echo packets in each stepping-stone. Packet round-trip times can be obtained from matched pairs of packets. "We then apply the round-trip time interpolation method
to obtain a round-trip time function and finally conduct Fast Fourier Transformation to the round-trip time function in each
stepping-stone host. Finally, we conduct a complete Fast Fourier Transformation analysis for the distribution of packet round-trip times and present the Fast Fourier Transformation analysis results in this paper," Yang explained. Yang et al.'s study appears in the latest issue of the Journal of Mobile Networks, Ubiquitous Computing, and Dependable Applications.
The Turner College's new marketing intern Lizzy Grant , a senior marketing major from Newnan who previously attended Gordon State College, where she played varsity soccer, and is scheduled to graduate from the Turner College in May of 2024, has hit the ground running in her new position. She recently played a large role in the creation of a video tour of the Synovus Center, the main campus home of the Turner College. The video helps to guide new students on where to go in the building and who they can talk to if they help. The video showcases the Student Services Center, the main lobby, and more. The video is played as part of a loop on video screens placed throughout the Synovus Center. Lizzy's list of activities at CSU is impressive. She is the Treasurer of the Turner College's Marketing Club, the President of Marketing for the Turner College's chapter of the Financial Management Association, and an Ambassador for the Turner College. She is also the Treasurer of her s
