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 – Remote Tools Add-on
The Remote Tools add-on provides extra features without adding bloat to the core plugin. For more details see the add-on page.

NB: Requires PHP >= 5.6
NEW – Support for 3rd-party Plugins

- 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.

incessant nagging to update to "pro" version if description mentioned that this "free" plugin isn't free, that would be acceptable, but the current practice is deceptive and unethical

negrusti 3. August 2019

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.

herculesnetwork 12. August 2018

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

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