Fail2WP vs WP Fail2Ban Redux

This WordPress plugin provides security functionality and integration with fail2ban. It does not require fail2ban to function. Basic security functionality includes: Disabling login with username (require e-mail address) Allow/Deny login from IP address, hostname (including wildcard support) Preventing user enumeration (?author=nnn) Less detailed error messages on login failures Minimum username length Blocking specific usernames from being used to register new users Requiring e-mail address matching for new user registrations Warning about new user role setting Blocking of portions or all of WordPress REST API Disabling of RSS and Atom feeds Removal of “Generator” information from HTML and feeds Detection of Cloudflare IP addresses for logging of actual IP addresses Blocking/Allowing logins from IP addresses, IP ranges, and/or hostnames Partially or fully disable XMLRPC access Monitoring administrator accounts for unexpected role/account changes The plugin also plays nicely with Fail2ban, which is an advanced way of blocking IP addresses dynamically upon suspicious behavior.

WP Fail2Ban Redux records various WordPress events to your server’s system log for integration with Fail2Ban. This plugin is (mostly) a drop-in replacement for WP fail2ban by Charles Lecklider. While WP fail2ban is a great plugin, there are a number of improvements that could be made. In order to facilitate these improvements, a major refactoring of the codebase was necessary. The core functionality between WP Fail2Ban Redux and WP fail2ban remains the same. WP Fail2Ban Redux is considered to be mostly a drop-in replacement, because all constants have been replaced with filters, and will, possibly, require some upgrade work. Don’t work it’s as simple as implementing the constants. The following events are recorded by default: Failed XML-RPC authentication attempts. Successful authentication attempts. Failed authentication attempts — differentiated by a user’s existence. Pingback errors. The following events can be enabled via filter: Pingback requests. Blocked user enumeration attempts. Authentication attempts for blocked usernames. Spammed comments. Extra documentation is available on the WP Fail2Ban Redux GitHub Wiki.
