Plugin / Authentication and xmlrpc log writer

Federico Rota

Description

Description

This plugin writes the log of failed access attempts (brute force attack) and invalids pingbacks requests ( by xmlrpc.php ). Very useful to process data via fail2ban.
You can activate the log for each pingback request feature and stop the user enumeration method (by redirecting to the home) with log.
If activated it remove the wordpress version number and meta generator in the head section of your site.
If activated it disable xmlrpc methods that require authentication, in order to avoid brute force attack by xmlrpc. Use this feature if you don’t need these xmlrpc methods.
If activated can kill multiple requests in a single xmlrpc call returning a 401 code on xmlrpc login error. This feature may be useful to prevent server overloading on brute force attack by xmlrpc.
You can also view your CUSTOM error log in the admin panel.

You can write error by

  1. SYSLOG
  2. APACHE ERROR_LOG
  3. CUSTOM a custom error log file (the used path need to be writable or APACHE ERROR LOG wil be used)
