🔒 Security Model

Jibril's security model is built on multiple layers of protection that work together to ensure robust, tamper-proof monitoring with minimal attack surface.

🛡️ Kernel-Level Safety​

✅ eBPF Verifier Protection​

The Linux kernel's eBPF verifier provides production-safe execution:

🔒 Memory Safety​

  • ✅ Every program verified before execution
  • 🚫 No unauthorized memory access
  • 🧱 Complete kernel/userspace isolation
  • 💚 Cannot crash the kernel

🎯 Execution Safety​

  • 🚫 No infinite loops possible
  • 📏 Bounded resource usage
  • ✅ All code paths validated
  • 🔐 Security policies enforced

🚫 Tamper-Proof Monitoring​

Jibril's kernel-level operation cannot be bypassed:

Why Jibril Cannot Be Evaded

  • 🎯 Kernel-level enforcement - Runs in kernel space, not userspace
  • 👑 Root cannot hide - Even privileged processes monitored
  • 📦 Container escapes visible - Monitors from host kernel perspective
  • 🚨 Unauthorized changes detected - eBPF map tampering flagged immediately
  • ⚠️ Rogue programs blocked - Unauthorized eBPF loads identified

🔐 Access Control​

Jibril implements least-privilege principles throughout its operation:

🛡️ Required Permissions​

Kernel Space Initialization

  • 👑 Root access for eBPF loading
  • 🔐 CAP_BPF or CAP_SYS_ADMIN required
  • 🚫 No unauthorized program inspection
  • ⚠️ Bypass attempts flagged

⬇️ Runtime Privileges​

Minimal Privilege After Init

  • ✅ Unnecessary capabilities dropped
  • 🔒 Minimal runtime privileges only
  • 🛡️ Prevents privilege escalation
  • 📉 Reduced attack surface

🧩 System Isolation​

🔧 Component Isolation​

Each system component runs independently to prevent cascading failures:

🧵 Plugin Threads​

  • 🔒 Dedicated thread per plugin
  • 🛡️ Failures contained to single plugin
  • ♻️ Automatic recovery mechanisms
  • ⚡ No interference between plugins

🔍 Detection Isolation​

  • 📋 Each detection recipe independent
  • 🔀 Distinct execution pathways
  • 🚫 No cross-contamination
  • ⚡ Safe parallel processing

🖥️ Reaction Sandboxing​

  • ⚡ Separate JavaScript VM per reaction
  • 🧱 Complete environment encapsulation
  • 🔒 Resource limits enforced
  • 🛡️ Cannot impact monitoring

💡 This isolation ensures that a single faulty component cannot compromise the entire system.

🧠 Detection Intelligence​

🎭 Confidential Detection Logic​

Jibril's core detection patterns remain proprietary:

🕵️ Security Through Obscurity​

  • 🔒 Hard to reverse-engineer patterns
  • 🛡️ Public guidelines show what, not how
  • 🎯 Adaptive detection evolves with threats
  • ✅ Minimizes evasion opportunities

⏱️ Smart Rate-Limiting​

  • 📊 Sophisticated event deduplication
  • 🔄 Repetitive events aggregated
  • 📉 Significant noise reduction
  • ✅ No security events lost

🤖 AI Powered Features​

  • 🧠 False positive identification and blocking
  • ✅ Automated detection classification
  • 📈 Continuous learning from patterns*
  • 🎯 Improved accuracy over time*

* Features backed by Garnet Security.

🌐 Data Immutability​

Once captured, event data cannot be modified:

🔐 Forensic Integrity​

  • 🛡️ Tamper-proof evidence collection
  • 🔑 Cryptographic hashing ensures integrity
  • 📋 Trustworthy audit trails
  • 🔍 Reliable investigation data

📊 Complete Context​

  • 🎯 Full system state at event time
  • 🌳 Process ancestry preserved
  • 🔧 Environment and arguments captured
  • 🌐 Network peer information retained

✅ Compliance Readiness​

Jibril's architecture supports multiple regulatory frameworks:

🌍 GDPR-Focused​

Privacy by Design

  • 📊 Metadata only (no file contents)
  • 🔒 Filenames, PIDs, timestamps
  • 🚫 No sensitive data collection
  • 🎯 Future anonymization support

📋 ISO 27001​

Security Framework Support

  • 📝 Comprehensive audit logging
  • 🔐 Granular access controls
  • 🚨 Tamper alerting mechanisms
  • ✅ Compliance-ready architecture
