这是我的 Netgear 6300 路由器 2 天的过滤日志。看来我经常受到 SMURF 攻击。
根据我的路由器设置，我似乎受到了保护。我没有选中“禁用端口扫描和 DoS 保护”。
我应该担心吗？

答案1
蓝精灵：
以小增量从实体中获取或给予实体。
为了制造甲基苯丙胺，毒品制造者让“蓝精灵”每天购买 2 盒 Advil 感冒药和鼻窦药，直到足够为止。
（分布式）DoS 攻击：
使服务器超载并将其瘫痪，从而“拒绝”向任何为了合法目的连接到服务器的人提供服务。
有人正在缓慢地占用您的所有带宽并试图破坏……某些东西。您运行 Web 服务器吗？如果没有，那么恶意软件完全有可能像僵尸网络一样缓慢地使您的计算机发起 DoS 攻击。
