# Fail2Ban filter to block web requests for scripts (on non scripted websites)
|
||
|
|
#
|
||
|
|
# This matches many types of scripts that don't exist. This could generate a
|
||
|
|
# lot of false positive matches in cases like wikis and forums where users
|
||
|
|
# no affiliated with the website can insert links to missing files/scripts into
|
||
|
|
# pages and cause non-malicious browsers of the site to trigger against this
|
||
|
|
# filter.
|
||
|
|
#
|
||
|
|
# If you'd like to match specific URLs that don't exist see the
|
||
|
|
# apache-botsearch filter.
