The paper introduces Kumo, a novel security-focused simulator that enables controlled analysis of resource sharing and scheduling risks in serverless cloud environments, demonstrating that scheduler c…
The paper proposes an architectural proxy (MCP) to enforce robust, reliable tool access control for LLM agents, demonstrating that this structural enforcement is necessary because prompt-based restric…
The paper introduces a secure, manifest-based framework that allows unprivileged processes to safely update and promote narrowly scoped privileged software components without requiring full administra…
PS-UIE proposes a privilege-separated architecture to continuously enforce the integrity of file-backed user-space executable objects within Confidential Virtual Machines (CVMs) like AMD SEV-SNP.

Grimlock is an Agent Guard that enhances security for high-agency systems by enforcing identity, authorization, and scope-bound communication through eBPF and attested TLS channels, without modifying…
The paper introduces PAuth, a new authorization model that grants agents only the precise permissions needed for a specific natural-language task, preventing overprivileging inherent in existing opera…
The paper proposes an attestation-aware promotion gate to mitigate supply-chain risks in LLM pipelines by cryptographically verifying and enforcing claims about training and release artifacts before d…
