Sharing of network data between organizations is desperately needed as attackers bounce between targets in different security domains and launch attacks across security domains. Anonymization to protect private/sensitive information has emerged as a promising approach to sharing network data between security domains. However, a fundamental tradeoff exists between the anonymization of data for privacy protection and the utility of anonymized for security analysis. While many researchers have referred to this tradeoff, no one has characterized it with testing. In this paper we present a testing framework we have developed to characterize privacy/analysis anonymization tradeoffs along with some preliminary results.
