8.  Security Considerations

   This MIB module defines objects for the configuration, monitoring,
   and notification of the Neighborhood Discovery Protocol [RFC6130].
   NHDP allows routers to acquire topological information up to two hops
   away by virtue of exchanging HELLO messages.  The information
   acquired by NHDP may be used by routing protocols.  The neighborhood
   information, exchanged between routers using NHDP, serves these
   routing protocols as a baseline for calculating paths to all
   destinations in the MANET, relay set selection for network-wide
   transmissions, etc.

   There are a number of management objects defined in this MIB module
   with a MAX-ACCESS clause of read-write and/or read-create.  Such
   objects may be considered sensitive or vulnerable in some network
   environments.  The support for SET operations in a non-secure
   environment without proper protection can have a negative effect on
   network operations.  These are the tables and objects and their
   sensitivity/vulnerability:

   o  nhdpIfStatus - This writable object turns on or off the NHDP
      process for the specified interface.  If disabled, higher-level
      protocol functions, e.g., routing, would fail, causing network-
      wide disruptions.

   o  nhdpHelloInterval, nhdpHelloMinInterval, and nhdpRefreshInterval -
      These writable objects control the rate at which HELLO messages
      are sent on an interface.  If set at too high a rate, this could
      represent a form of denial-of-service (DoS) attack by overloading
      interface resources.

   o  nhdpHystAcceptQuality, nhdpHystRejectQuality, nhdpInitialQuality,
      and nhdpInitialPending - These writable objects affect the
      perceived quality of the NHDP links and hence the overall
      stability of the network.  If improperly set, these settings could
      result in network-wide disruptions.

   o  nhdpInterfaceTable - This table contains writable objects that
      affect the overall performance and stability of the NHDP process.
      Failure of the NHDP process would result in network-wide failure.
      Particularly sensitive objects from this table are discussed in
      the previous list items.  This is the only table in the NHDP-MIB
      module with writable objects.

   Some 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.  It is thus important to
   control even GET and/or NOTIFY access to these objects and possibly

Top      Up      ToC       Page 63 
   to even encrypt the values of these objects when sending them over
   the network via SNMP.  These are the tables and objects and their
   sensitivity/vulnerability:

   o  nhdpDiscIfSetTable - The object contains information on discovered
      neighbors, specifically their IP address in the
      nhdpDiscIfSetIpAddr object.  This information provides an
      adversary broad information on the members of the MANET, located
      within this single table.  This information can be used to
      expedite attacks on the other members of the MANET without having
      to go through a laborious discovery process on their own.  This
      object is the index into the table and has a MAX-ACCESS of 'not-
      accessible'.  However, this information can be exposed using SNMP
      operations.

   MANET technology is often deployed to support communications of
   emergency services or military tactical applications.  In these
   applications, it is imperative to maintain the proper operation of
   the communications network and to protect sensitive information
   related to its operation.  Therefore, it is RECOMMENDED to provide
   support for the Transport Security Model (TSM) [RFC5591] in
   combination with TLS/DTLS [RFC6353].

   SNMP versions prior to SNMPv3 did not include adequate security.
   Even if the network itself is secure (for example by using IPsec),
   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.

   Implementations MUST provide the security features described by the
   SNMPv3 framework (see [RFC3410]), including full support for
   authentication and privacy via the User-based Security Model (USM)
   [RFC3414] with the AES cipher algorithm [RFC3826].  Implementations
   MAY also provide support for the Transport Security Model (TSM)
   [RFC5591] in combination with a secure transport such as SSH
   [RFC5592] or TLS/DTLS [RFC6353].

   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.

9.  Applicability Statement

   This document describes objects for configuring parameters of the
   Neighborhood Discovery Protocol [RFC6130] process on a router.  This
   MIB module, denoted NHDP-MIB, also reports state, performance
   information, and notifications.  This section provides some examples
   of how this MIB module can be used in MANET network deployments.  A
   fuller discussion of MANET network management use cases and
   challenges will be provided elsewhere.

   NHDP is designed to allow routers to automatically discover and track
   routers one hop remote (denoted "neighbors") and routers two hops
   remote (denoted "two-hop neighbors").  This information is used by
   other MANET protocols in operation on the router to perform routing,
   multicast forwarding, and other functions with ad hoc and mobile
   networks.  In the following, three example scenarios are listed where
   this MIB module is useful:

   o  For a Parking Lot Initial Configuration Situation - It is common
      for the vehicles comprising the MANET being forward deployed at a
      remote location, e.g., the site of a natural disaster, to be off-
      loaded in a parking lot where an initial configuration of the
      networking devices is performed.  The configuration is loaded into
      the devices from a fixed location Network Operation Center (NOC)
      at the parking lot, and the vehicles are stationary at the parking
      lot while the configuration changes are made.  Standards-based
      methods for configuration management from the co-located NOC are
      necessary for this deployment option.

   o  For Mobile Vehicles with Low-Bandwidth Satellite Link to a Fixed
      NOC - Here, the vehicles carrying the MANET routers carry multiple
      wireless interfaces, one of which is a relatively low-bandwidth,
      on-the-move satellite connection that interconnects a fix NOC to
      the nodes of the MANET.  Standards-based methods for monitoring
      and fault management from the fixed NOC are necessary for this
      deployment option.

   o  For Fixed NOC and Mobile Local Manager in Larger Vehicles - for
      larger vehicles, a hierarchical network management arrangement is
      useful.  Centralized network management is performed from a fixed
      NOC while local management is performed locally from within the
      vehicles.  Standards-based methods for configuration, monitoring,
      and fault management are necessary for this deployment option.
