SOFTWARE DEFINED NETWORK SECURITY

Software-defined networking (SDN) has emerged as an efficient network technology capable of supporting the dynamic nature of future network functions and intelligent applications while lowering operating costs through simplified hardware, software, and management. However, this new networking model brings with it challenges of network performance, scalability, security, and interoperability.

At CSIT, significant research has been undertaken in the area of traffic management technologies and flow-based, performance-driven network hardware development. We build on this expertise in our current research on SDN targeting the specific security challenges of SDN and deriving advanced security architectures without compromising network performance.
