The director can remotely manage the configuration of the fielded sensors. The remote management tool is a Java-based tool called nrconfigure.

Through nrconfigure, the user can define attack signatures on the remote sensors. Cisco supplies built-in signatures of known attacks, and users can create custom signatures to match the needs of their corporate networks.

Version management is also offered through nrconfigure, and a rollback feature is available that allows the user to go back to a previous configuration at any time.
