This workshop is held in conjunction with ICCCN 2017 which is co-sponsored by IEEE communication society. It provides a forum for researchers to explore promising new approaches to enable enterprises to quickly determine courses of action in response to ever changing computer network threats. Emphasis will be focused on building a sustained ecosystem for network security and using big data analytics techniques to determine appropriate responses to prevent massive attack events by neutralizing threats before they have a chance to gather momentum. To this end effective and safe automation and integration of security tools are critical. Topics of interest include, but not limited to:

· Cyber threat information sharing standards, ontologies, and infrastructure
· Assessing the reputation of cyber threat intelligence sources
· Course of action planning based on shared information
· Enrichment of shared threat information
· Application of big data analytics to identify threats
· Visualization of logs and attack information
· Integration of network security responses
· Orchestration of responses to threats
· Automation of responses
· Safety controls for automation
· Network resiliency
· Network end point security, including mobile device
· Wireless network security
· Security of IoT and cyber-physical systems
· Education and curriculum development related to topics listed above
