Securing NRPE with certificate based authentication
Posted by Michael Medin at 2012-12-02
NRPE is a common easy to use option for monitoring remote machines from Nagios or Icinga. Unfortunately NRPE, with **out of the box setup,* is not what I would consider secure.*
This tutorial looks at how you can secure your NRPE traffic by using NSClient++ both as a client and server (yes it runs on Linux as well) in conjunction with SSL certificates to provide certificate based authentication.
