+# 4.71 确保 nftables 未安装
+
+## 安全等级
+
+- level 1
+
+## 描述
+
+`nftables`是Linux内核的一个子系统，它提供网络包/数据报/帧的过滤和分类功能，是`iptables`的替代品。同时运行这两个子系统可能导致冲突。
+
+## 修复建议
+
+移除`nftables`。
+
+1. 执行以下命令以移除`nftables`：
+
+```bash
+# yum remove nftables
+```
+
+## 扫描检测
+
+确保`nftables`已经删除。
+
+1. 执行以下命令，验证`nftables`是否已经移除：
+
+```bash
+# rpm -q nftables
+package nftables is not installed
+```
+
+如果命令执行后返回结果如上所示，则视为通过此项检查。
+
