Next, I'll give an example of an old (but still widely used) attack, which involves sniffing passwords right off the network.

接下来，我将给出一个老的(但仍广泛使用的)攻击示例，它就在网下嗅探密码。

youdao

From packet sniffing to analysis to alerting you or an admin to possible intrusions, Snort protects your work from attack.

从包嗅探、分析一直到向您或管理员发出可能出现入侵的警报，Snort能够保护您的工作成果，使之免受攻击。

youdao

For example, in the simplest case, network sniffing is used to obtain passwords, and those passwords are then used to mount an application-level attack.

例如，在最简单的情况中，网络嗅探能够用于获取密码，然后这些密码可以用于进行应用级攻击。
