Top Highlights Spark’s lack of robust policy enforcement mechanisms poses risks of data breaches from malicious users and cloud managers exploiting physical plan manipulations or system vulnerabilities. The proposed framework, Laputa, introduces pattern matching-based policy checks at the physical plan level, enabling fine-grained and generally applicable policy enforcement on Spark applications. Laputa employs confidential computing to partition Spark applications, safeguarding the entire data analysis pipeline from malicious actors while maintaining ease of use with minimal modifications for users. Evaluation results show that Laputa effectively blocks malicious activities with moderate performance overheads, enhancing security without significantly sacrificing functionality. The Issue The…
