Internet-Draft   MIB Module for the RPKI-Router Protocol      March 2012


1.  Introduction

   This document defines a portion of the Management Information Base
   (MIB) for use with network management protocols in the Internet
   community.  In particular, it defines objects used for monitoring the
   RPKI Router protocol [I-D.ietf-sidr-rpki-rtr].

1.1.  Requirements Language

   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 RFC 2119 [RFC2119].


2.  Internet-Standard Management Framework

   For a detailed overview of the documents that describe the current
   Internet-Standard Management Framework, please refer to section 7 of
   [RFC3410].  Managed objects are accessed via a virtual information
   store, termed the Management Information Base or MIB.  MIB objects
   are generally accessed through the Simple Network Management Protocol
   (SNMP).  Objects in the MIB are defined using the mechanisms defined
   in the Structure of Management Information (SMI).  This document
   specifies a MIB module that is compliant to the SMIv2, which is
   described in STD 58, [RFC2578], STD 58, [RFC2579] and STD 58,
   [RFC2580].


3.  Overview

   The objects defined in this document are used to monitor the RPKI
   Router protocol [I-D.ietf-sidr-rpki-rtr].  The MIB module defined in
   this draft is broken into these tables: the RPKI Router Cache Server
   (connection) Table, the RPKI Router Cache Server Errors Table, and
   the RPKI Router Prefix Origin Table.

   The RPKI Router Cache Server Table contains information about state
   and current activity of connections with the RPKI Router Cache
   Servers.  It also contains counters for the number of messages
   receibd and sent plus the number of accouncements, withdrawals and
   active records.  The RPKI Router Cache Server Errors Table contains
   counters of occurences of errors on the connections (if any).  The
   RPKI RoOuter Prefix Origin Table contains IP prefixes with their
   minumum and maximum prefix lengths and the Origin AS.  This data is
   the collective set of information received from all RPKI Cache
   Servers that the router is connected with.  The Cache Servers are
   running the RPKI Router protocol.

Internet-Draft   MIB Module for the RPKI-Router Protocol      March 2012


   Two Notification have been defined to inform a Network Management
   Station (NMS) or operators about changes in the connection state of
   the connections listed in the RPKI Cache Server (Connection) Table.


4.  Definitions

   The Following MIB module imports definitions from [RFC2578], STD 58,
   [RFC2579] STD 58, [RFC2580], [RFC4001], [RFC2287].  That means we
   have a normative reference to those documents.

   The MIB module also has a normative reference to the RPKI Router
   protocol [I-D.ietf-sidr-rpki-rtr].  Furthermore, for background and
   informative information, the MIB module refers to [RFC1982],
   [RFC2385], [RFC4252], [RFC5246], [RFC5925].

5.  IANA Considerations

   The MIB module in this document will required an IANA assigned OBJECT
   IDENTIFIER within the SMI Numbers registry.  For example, replacing
   XXX below:

         Descriptor        OBJECT IDENTIFIER value
         ----------        -----------------------

Internet-Draft   MIB Module for the RPKI-Router Protocol      March 2012


         rpkiRouter            { mib-2 XXX }


6.  Security Considerations

   There are no management objects defined in this MIB module that have
   a MAX-ACCESS clause of read-write and/or read-create.  So, if this
   MIB module is implemented correctly, then there is no risk that an
   intruder can alter or create any management objects of this MIB
   module via direct SNMP SET operations.

   Most of the readable objects in this MIB module (i.e., objects with a
   MAX-ACCESS other than not-accessible) may be considered sensitive or
   vulnerable in some network environments.  They are vulnerable in the
   sense that when an intruder sees the information in this MIB module,
   then it might help him/her to setup a an attack on the router or
   cache server.  It is thus important to control even GET and/or NOTIFY
   access to these objects and possibly to even encrypt the values of
   these objects when sending them over the network via SNMP.

   SNMP versions prior to SNMPv3 did not include adequate security.
   Even if the network itself is secure (for example by using IPSec),
   even then, there is no control as to who on the secure network is
   allowed to access and GET/SET (read/change/create/delete) the objects
   in this MIB module.

   It is RECOMMENDED that implementers consider the security features as
   provided by the SNMPv3 framework (see [RFC3410], section 8),
   including full support for the SNMPv3 cryptographic mechanisms (for
   authentication and privacy).

   Further, deployment of SNMP versions prior to SNMPv3 is NOT
   RECOMMENDED.  Instead, it is RECOMMENDED to deploy SNMPv3 and to
   enable cryptographic security.  It is then a customer/operator
   responsibility to ensure that the SNMP entity giving access to an
   instance of this MIB module is properly configured to give access to
   the objects only to those principals (users) that have legitimate
   rights to indeed GET or SET (change/create/delete) them.
