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.
