# Fail2Ban filter to match web requests for selected URLs that don't exist
|
||
|
|
#
|
||
|
|
# This filter is aimed at blocking specific URLs that don't exist. This
|
||
|
|
# could be a set of URLs places in a Disallow: directive in robots.txt or
|
||
|
|
# just some web services that don't exist caused bots are searching for
|
||
|
|
# exploitable content. This filter is designed to have a low false positive
|
||
|
|
# rate due.
|
||
|
|
#
|
||
|
|
# An alternative to this is the apache-noscript filter which blocks all
|
||
|
|
# types of scripts that don't exist.
|
||
|
|
#
|
||
|
|
#
|
||
|
|
# This is normally a predefined list of exploitable or valuable web services
|
||
|
|
# that are hidden or aren't actually installed.
