HardWhale: A Hardware-Isolated Network Security Enforcement System for Cloud Environments
Bibliographic record
Abstract
With the increasing popularity of containers for deploying microservices, ensuring the security of container networks has become a vital concern. However, current security solutions rely on a host's operating system (OS) to enforce network policies for container traffic. This design incurs severe overhead and cannot guarantee container network security when attackers gain access to the host's OS. Therefore, we propose HardWhale, a hardware-isolated network security enforcement system for containers that delivers high-performance and robust network security without depending on the host's OS. HardWhale leverages a smartNIC, physically isolating the entire container traffic inspection stack from the host and accelerating inspection tasks. Inspection policies securely reside within the smartNIC and are updated in runtime without involving the host, due to our isolated policy management mechanism. This design ensures robust network security for containers, even if the host is exposed to attackers. Evaluations show that HardWhale protects containers against various network attacks in compromised environments and improves HTTP throughput threefold and HTTP latency 2.3-fold compared to state-of-the-art solutions.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
