5. Privacy Protection vs. Computational Complexity 5 Strongest Protection Slow Performance Limited Query Capabilities Offline Mode Only Strong Protection Moderate Performance Moderate Query Capabilities Limited Operational Mode Best-effort Protection Fast Performance Flexible Query Capabilities Supports Operational Mode Performance Differential Privacy Searchable Encryption Syntactic Privacy (k- anonymity, l-diversity) Tradeoff in privacy and computation overheads

6. Preserving Data Privacy in AMIS 6

7. Measurement Data Management and Processing Decentralized hierarchical resource management common data integration schema to be used across analytic, communication, and storage components Distributed system for high volume streaming data processing GUI, reporting tools, data repo 7

8. Network Flow Analytics Distinguish traffic matrix and traffic types –identify project association of traffic flows –file transfers, interactive sessions, short-lived Stochastic modeling –descriptive statistics –auto-correlation Derive network activity patterns and trends Provide insights to network management –What if scenarios 8
