While thisprotocol was originally developed on the University of CaliforniaBerkeley Software Distribution (BSD) TCP/IP system implementations, itsvalue to operations and management has led it to be ported to many otheroperating systems as well as being embedded into many other networkeddevices. This document is a product of the Security Issues in NetworkEvent Logging Working Group of the IETF.
