网络命名空间
Linux Namespace机制的七种隔离类型之一，每个命名空间拥有独立的网络栈（网络接口、路由表、iptables规则、端口空间），是容器网络隔离的基石，在Linux内核3.0之后趋于成熟
Timeline (last 90 days)
In production environments, structural network isolation should be implemented using network namespaces (such as no default route and allowing access only to an egress proxy), because application-layer checks can be bypassed by creative tool calls.
A network namespace is a network isolation mechanism provided by the Linux kernel; each namespace has its own independent network interfaces, routing table, and firewall rules.
Using eBPF or network namespaces allows monitoring and restricting an agent's outbound connections, implementing a destination-address allowlist.
A network namespace is Linux's mechanism for isolating the network stack; each namespace has its own network interfaces, routing table, firewall rules, and port space; attacking across namespaces requires a kernel vulnerability rather than a simple configuration change.
