Kernel Sandboxing

A security technique that isolates processes from interacting with the operating system kernel to prevent exploitation.

Understanding:


Kernel sandboxing isolates untrusted applications from the OS kernel to prevent security breaches.

Common Applications and Use Cases:


  • Web Browsers (Chrome, Firefox) – Prevents malware from affecting the OS.

  • Mobile Security (Android, iOS) – Isolates apps from critical system components.

  • Virtual Machines (VMs) – Enhances container security.

Best Practices and Security Considerations:


  • Use Hardened Sandbox Mechanisms – Enforce strong process isolation.

  • Apply Mandatory Access Controls (SELinux, AppArmor) – Limits app permissions.

  • Enable Secure Boot & Trusted Execution Environments (TEE) – Ensures system integrity.
