Beschreibung

fail2ban is one of the simplest and most effective security measures you can implement to prevent brute-force attacks.

WP fail2ban logs all login attempts – including via XML-RPC, whether successful or not, to syslog using LOG_AUTH. For example:

Oct 17 20:59:54 foobar wordpress(www.example.com)[1234]: Authentication failure for admin from 192.168.0.1
Oct 17 21:00:00 foobar wordpress(www.example.com)[2345]: Accepted password for admin from 192.168.0.1

WPf2b comes with three fail2ban filters: wordpress-hard.conf, wordpress-soft.conf, and wordpress-extra.conf. These are designed to allow a split between immediate banning (hard) and the traditional more graceful approach (soft), with extra rules for custom configurations.

Features

NEW – Support for 3rd-party Plugins
Version 4.2 introduces a simple API for authors to integrate their plugins with WPf2b, with 2 experimental add-ons:
- Contact Form 7
- Gravity Forms
  NB: Requires PHP >= 5.6
CloudFlare and Proxy Servers
WPf2b can be configured to work with CloudFlare and other proxy servers. For an overview see WP_FAIL2BAN_PROXIES.
Comments
WPf2b can log comments (see WP_FAIL2BAN_LOG_COMMENTS) and attempted comments (see WP_FAIL2BAN_LOG_COMMENTS_EXTRA).
Pingbacks
WPf2b logs failed pingbacks, and can log all pingbacks. For an overview see WP_FAIL2BAN_LOG_PINGBACKS.
Spam
WPf2b can log comments marked as spam. See WP_FAIL2BAN_LOG_SPAM.
Block User Enumeration
WPf2b can block user enumeration. See WP_FAIL2BAN_BLOCK_USER_ENUMERATION.
Work-Arounds for Broken syslogd
WPf2b can be configured to work around most syslogd weirdness. For an overview see WP_FAIL2BAN_SYSLOG_SHORT_TAG and WP_FAIL2BAN_HTTP_HOST.
Blocking Users
WPf2b can be configured to short-cut the login process when the username matches a regex. For an overview see WP_FAIL2BAN_BLOCKED_USERS.
mu-plugins Support
WPf2b can easily be configured as a must-use plugin – see Configuration.

Was simple and great plugin until some 4.x version where it added Freemius marketing component making calls to api.freemius.com. Have to revert to the older version for that reason. At some point the plugin was also vulnerable because of this component.

Been using this for a while now. Integration with fail2ban is pretty straight forward.

This plugin is perfect, essencial - thank you so much the best thing about this plugin after it works perfectly, is that it does not change the directories nor names of the configuration files, something unpleasant that always happens in plugins, you configure everything for the given file, and a certain directory of the plugin and in a new version unnecessarily the plugin changes the things of place. this plugin I have a long time, and I have a command to copy and paste the w2 fail2ban plugin settings to fail2ban, and things continue as usual. Thanks to the developer. Who does not give 5 stars, does not know how to use it.

Great plugin, that worked first time. On Amazon Linux / Centos the location of the log file is /var/log/messages

sillystring März 6, 2017

Great idea if you host your own server and use fail2ban. Thanks!
