The Network Security Research Group is part of Network Systems Research at the Communications Research Centre (CRC) Canada. The Group conducts research in technologies and techniques to advance the current state of network security.

With technical expertise arising from two decades of R&D supporting the design of secure and survivable networks for DND, the research team is well positioned to address basic cybersecurity research problems.

Because of the complexity of networks, network failures and attacks on networks, network management centers require automated tools to simplify network control and reconfiguration. As much information as possible about the network infrastructure, knowledge of host connectivity, network topology and equipment configuration is essential for effectively deploying and positioning network sensors, intrusion detection systems and other defensive tools, such as firewalls, to detect and react to cyber-attacks. To support these requirements the Network Security research program is focused on three interrelated themes:

• Network Monitoring,
  
• Identification and Discovery, and
  
• Network Traffic Flow Analysis.
