Nessus扫出问题,请教解决方案

用Nessus 扫描自己的IIS机器发现:

Synopsis :
It is possible to enumerate web directories.
Description :
This plugin attempts to determine the presence of various
common dirs on the remote web server.

Plugin output :
The following directories were discovered:
/help, /html, /images, /js, /public, /search, /service, /styles, /member

While this is not, in and of itself, a bug, you should manually inspect
these directories to ensure that they are in compliance with company
security standards
