PAPER
RContainer: A Secure Container Architecture through Extending ARM CCA Hardware Primitives
Containers have become widely adopted in cloud platforms due to their efficient deployment and high resource utilization. However, their weak isolation has always posed a significant security concern. In this paper, we propose RContainer, a novel secure container architecture that protects containers from untrusted operating systems and enforces strong isolation among containers by extending ARM Confidential Computing Architecture (CCA) hardware primitives. RContainer introduces a small, trusted mini-OS that runs alongside the deprivileged OS, responsible for monitoring the control flow between the operating system and containers. Additionally, RContainer uses shim-style isolation, creating an isolated physical address space called con-shim for each container at the kernel layer through the Granule Protection Check mechanism. We have implemented RContainer on ARMv9-A Fixed Virtual Platform and ARMv8 hardware SoC for security analysis and performance evaluation. Experimental results demonstrate that RContainer can significantly enhance container security with a modest performance overhead and a minimal Trusted Computing Base (TCB).
ABOUT NDSS
The Network and Distributed System Security Symposium (NDSS) fosters information exchange among researchers and practitioners of network and distributed system security. The target audience includes those interested in practical aspects of network and distributed system security, with a focus on actual system design and implementation. A major goal is to encourage and enable the Internet community to apply, deploy, and advance the state of available security technologies.

PAPER
Secure Data Analytics in Apache Spark with Fine-grained Policy Enforcement and Isolated Execution
Cloud based Spark platform is a tempting approach for sharing data, as it allows data users to easily analyze the data while the owners to efficiently share the large volume of data. However, the absence of a robust policy enforcement mechanism on Spark hinders the data owners from sharing their data due to the risk of private data breach. In this respect, we found that malicious data users and cloud managers can easily leak the data by constructing a policy violating physical plan, compromising the Spark libraries, or even compromising the Spark cluster itself. Nonetheless, current approaches fail to securely and generally enforce the policies on Spark, as they do not check the policies on physical plan level, and they do not protect the integrity of data analysis pipeline. This paper presents Laputa, a secure policy enforcement framework on Spark. Specifically, Laputa designs a pattern matching based policy checking on the physical plans, which is generally applicable to Spark applications with more fine-grained policies. Then, Laputa compartmentalizes Spark applications based on confidential computing, by which the entire data analysis pipeline is protected from the malicious data users and cloud managers. Meanwhile, Laputa preserves the usability as the data users can run their Spark applications on Laputa with minimal modification. We implemented Laputa, and evaluated its security and performance aspects on TPC-H, Big Data benchmarks, and real world applications using ML models. The evaluation results demonstrated that Laputa correctly blocks malicious Spark applications while imposing moderate performance overheads.

Emerging Evidence Provides Basis for Opening Investigation of ICE Agent Who Killed Renee Good (Julia Gegenheimer, Just Security)
The Justice Department’s refusal to investigate ICE Agent Jonathan Ross’s killing of Renee Good breaks with decades of DOJ civil-rights practice and standards.
As a growing number of encounters between civilians and Department of Homeland Security agents — including the widely scrutinized fatal shooting of Renee Good in Minneapolis — are scrutinized in court records and on social media, federal officials are returning to a familiar response: self-defense.
