Syscall-Interception Sandbox
Infrastructure resourceSafety & SecuritySafety, Security & Governancearc:SyscallInterceptionSandbox
An execution sandbox that intercepts application system calls in a user-space kernel implementation, validating or rejecting them before they reach the host kernel.
Responsibility. Provides stronger-than-container isolation without per-container guest kernels.
Also known as: User-space kernel sandbox
Variant of Execution Sandbox abstract
When to choose. Choose when stronger isolation than standard containers is needed with modest overhead, e.g., interactive real-time services that cannot tolerate VM boot latency, provided the workload's syscalls are supported.

As stated by the sources; verify before use.
- Typically 10-20% performance degradation for syscall-intensive workloads (Ch9.3).
