Description: Topic: Secure Software-Defined Integrated Space Communication Service Networks
Location: Lester W. Cory Conference Room, Science & Engineering Building (SENG), Room 213A
Abstract:
Software-defined networking (SDN) has enabled elastic networking and resource distribution in cloud computing. The centralization and separation of the control plane also offers a high degree of network configurability and management, which can be used to mitigate and manage threats to the network. This thesis examines the potential role of SDN in enabling flexible and secure space communication networks. Space communication networks have historically been restricted and circuit switching in these networks has been a manual process. The networking security needs of spacecraft missions and their associated assets are evaluated, along with the challenges, opportunities and considerations with SDN. A risk assessment identifies vulnerabilities in an SDN-based communications architecture. Security challenges introduced into the network from integrating SDN are also considered. A risk register summarizes the severity of the attack outcomes, as well as occurrence likelihood. Denial-of-Service is identified as a risk that existing controls for space communication networks wouldn't fully address in this scenario. Flow and port sampling with centralized intelligence is evaluated and tested as a tool for identifying malicious behavior on the network, while network flow reconfiguration is used to isolate attacks. This thesis proposes a solution to spacecraft communication networks using SDN with mitigation strategies for meeting security challenges and improving asset resilience.
Note: All ECE Graduate Students are ENCOURAGED to attend.
