問題 #104
Which Linux kernel feature restricts a process's access to a subset of system calls, commonly used by container runtimes and sandboxing tools to reduce attack surface?

A. namespaces
B. capabilities
C. seccomp
D. cgroups

答案：C

解題說明：
Secure Computing Mode (seccomp) is a Linux kernel feature that allows a process to restrict the set of system calls it is permitted to make, typically by loading a filter (often defined using BPF) that allows, denies, or traps specific syscalls. This significantly reduces a process's attack surface by preventing it from invoking syscalls it does not need, and is widely used by container runtimes like Docker and by sandboxing frameworks. cgroups control resource usage, namespaces provide isolated views of system resources, and capabilities divide root privileges into discrete units.
