bombini
Bombini: eBPFベースのセキュリティ監視およびサンドボックスエージェント Bombini は、Aya ライブラリを使用して完全に Rust で書かれた eBPF ベースのセキュリティエージェントであり、LSM Linux Security Module BPF フック上に構築されています。その中核として、Bombini は Detector と呼ばれるモジュール式コンポーネントを採用しており、各コンポーネントが特定の種類のシステムイベントの監視と報告を担当します。 はじめに まず、互換性に関する問題を確認してください。 現在最も便利な方法は、Bombini...
agent
Bomfather Agent Bomfather Agentは、カーネル空間で動作し、ポリシーに基づいてアクションをブロックするeBPFベースのエージェントです。 私たちは、既存のソリューションで抱えていた問題を解決するためにこのエージェントを開発しました。 1. セットアップと使用が複雑すぎた。 2. 遅く、非効率だった。 3. そして、たとえセットアップが簡単であっても、セキュリティが不十分であったり、さまざまなユースケースに対応できるだけの柔軟性がなかった。 これらの点は、このプロジェクト全体を通じた私たちの北極星です。すべての機能と開発は、これらの点を満たすことを目的としていま...
