Description
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
The plugin also plays nicely with Fail2ban, which is an advanced way of blocking IP addresses dynamically upon suspicious behavior.
