9. National Center for Supercomputing Applications Network/System/Audit Log Anonymization NCSA produces ~5 GBytes of logs per day. Real-world logs are useful for investigations, education, testing of tools, and network/security research. However, real-world logs often contain sensitive information. –Privacy issues exist for both the individual users and the organization. –Network topology could be useful to attackers. –Services running on machines and trust relationships between systems could be useful to attackers.

10. National Center for Supercomputing Applications FLAIM – Framework for Log Anonymization and Information Management Solution – Anonymization to meet the needs of both parties –Data owner is concerned with privacy/security –Analyst is concerned with information loss –FLAIM has a rich policy language expressive enough to often define policies that meet needs of both E.g., one can obscure IP addresses, but preserve the subnet structure for networking researchers FLAIM is very flexible –Modular, allowing I/O modules for multiple logs to be built –Plethora of anonymization primitives to apply to many fields http://flaim.ncsa.uiuc.edu/flaim.html

11. National Center for Supercomputing Applications FLAIM – Into the future Analyze trade-offs between information loss and privacy –Create a metric of log utility and analyze effect of anonymization on metric. –Create a metric of the strength of an anonymization scheme. We can move beyond computer/network logs –Reuse the anonymization engine and policy engine, a.ka. FLAIM-Core. –Module API is flexible enough to support any data in a record/field format.
