Using the NETCONF Protocol over Transport Layer Security (TLS)
with Mutual X.509 Authentication
Abstract
The Network Configuration Protocol (NETCONF) provides mechanisms to
install, manipulate, and delete the configuration of network devices.
This document describes how to use the Transport Layer Security (TLS)
protocol with mutual X.509 authentication to secure the exchange of
NETCONF messages. This revision of RFC 5539 documents the new
message framing used by NETCONF 1.1 and it obsoletes RFC 5539.

RFC 7589 NETCONF over TLS June 2015
1. Introduction
The NETCONF protocol [RFC6241] defines a mechanism through which a
network device can be managed. NETCONF is connection-oriented,
requiring a persistent connection between peers. This connection
must provide integrity, confidentiality, peer authentication, and
reliable, sequenced data delivery.
This document defines how NETCONF messages can be exchanged over
Transport Layer Security (TLS) [RFC5246]. Implementations MUST
support mutual TLS certificate-based authentication [RFC5246]. This
assures the NETCONF server of the identity of the principal who
wishes to manipulate the management information. It also assures the
NETCONF client of the identity of the server for which it wishes to
manipulate the management information.
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in [RFC2119].
2. Connection Initiation
The peer acting as the NETCONF client MUST act as the TLS client.
The TLS client actively opens the TLS connection and the TLS server
