GULP: Do You Really Know Who Your Users Are?

Thursday, April 12 | 8:00AM–9:00AM ET | Maryland Ballroom D, Fifth Floor
Session Type: Breakout Session
Delivery Format: Interactive Presentation
Columbia University uses the "free love" method of network IP management. Instead of registration, we rely on GULP (Grand Unified Logging Program), using authentication log entries and DHCP. This gives an excellent picture of who is using our network and from where. We mine that data to discover things like missing students and compromised passwords. In 2016, GULP was updated to include real-time data from our controlled access system. This gives us immediate access to the actual location of people as they swipe into buildings, making the discovery of stolen accounts more accurate.

Outcomes: Understand why preregistration is not needed to know who your users are * See how real-time data can be used to discover compromised accounts * See a practical application of big data processing
