RFC 4807              IPsec SPD configuration MIB             March 2007


1.  Introduction

   This document defines a MIB module for configuration of an IPsec
   security policy database (SPD).  The IPsec model this MIB is designed
   to configure is based on the "IPsec Configuration Policy Model"
   (IPCP) [RFC3585].  The IPCP's IPsec model is, in turn, derived from
   the Distributed Management Task Force's (DMTF) IPsec model (see
   below) and from the IPsec model specified in RFC 2401 [RFC2401].
   Note: RFC 2401 has been updated by RFC 4301 [RFC4301], but this
   implementation is based on RFC 2401.  The policy-based packet
   filtering and the corresponding execution of actions configured by
   this MIB is of a more general nature than for IPsec configuration
   only, such as for configuration of a firewall.  It is possible to
   extend this MIB module and add other packet-transforming actions that
   are performed conditionally on an interface's network traffic.

   The IPsec- and IKE-specific actions are as documented in
   [IPsec-ACTION] and [IKE-ACTION], respectively, and are not documented
   in this document.

2.  Terminology

   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].

3.  The 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
   RFC 3410 [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 memo specifies a MIB
   module that is compliant to the SMIv2, which is described in STD 58,
   RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580
   [RFC2580].

4.  Relationship to the DMTF Policy Model

   The Distributed Management Task Force (DMTF) has created an object
   oriented model of IPsec policy information known as the IPsec Policy
   Model White Paper [IPPMWP].  The "IPsec Configuration Policy Model"
   (IPCP) [RFC3585] is based, in large part, on the DMTF's IPsec policy
   model and on RFC 2401 [RFC2401].  The IPCP document describes a model

RFC 4807              IPsec SPD configuration MIB             March 2007


   for configuring IPsec.  This MIB module is a task-specific derivation
   (i.e., an SMIv2 instantiation) of the IPCP's IPsec configuration
   model for use with Simple Network Management Protocol version 3
   (SNMPv3).

   The high-level areas where this MIB module diverges from the IPCP
   model are:

   o  Policies, Groups, Conditions, and some levels of Actions are
      generically named.  In other words, IPsec-specific prefixes like
      "SA" (Security Association), or "IPsec", are not used.  This
      naming convention is used because packet classification and the
      matching of conditions to actions is more general than IPsec.  The
      tables in this document can possibly be reused by other packet-
      transforming actions, which need to conditionally act on packets
      matching filters.

   o  Filters are implemented in a more generic and scalable manner,
      rather than enforcing the condition/filtering pairing of the IPCP
      and its restrictions upon the user.  This MIB module offers a
      compound filter object providing greater flexibility for complex
      filters than the IPCP.

5.  MIB Module Overview

   The MIB module is modularized into several different parts: rules,
   filters, and actions.

   The rules section associates endpoints and groups of rules, and
   consists of the spdEndpointToGroupTable, spdGroupContentsTable, and
   the spdRuleDefinitionTable.  Each row of the spdRuleDefinitionTable
   connects a filter to an action.  It should also be noted that by
   referencing the spdCompoundFilterTable, the spdRuleDefinitionTable's
   filter column can indicate a set of filters to be processed.
   Likewise, by referencing the spdCompoundActionTable, the
   spdRuleDefinitionTable's action column can indicate multiple actions
   to be executed.

   This MIB is structured to allow for reuse through the future creation
   of extension tables that provide additional filters and/or actions.
   In fact, the companion documents to this one ([IPsec-ACTION] and
   [IKE-ACTION]) do just that and define IPsec- and IKE-specific actions
   to be used within this SPD configuration MIB.  Note: it is expected
   that, in order to function properly, extension action MIBs may impose
   additional limitations on the objects in this MIB and how they can be
   used with the extended actions.  An extension action may only support
   a subset of the configuration options available in this MIB.




Baer, et al.                Standards Track                     [Page 4]

RFC 4807              IPsec SPD configuration MIB             March 2007


   The filter section of the MIB module is composed of the different
   types of filters in the Policy Model.  It is made up of the
   spdTrueFilter, spdCompoundFilterTable, spdSubfiltersTable
   spdIpHeaderFilterTable, spdIpOffsetFilterTable, spdTimeFilterTable,
   spdIpsoHeaderFilterTable.

   The action section of this MIB module contains only the simple static
   actions required for the firewall processing that an IPsec SPD
   implementation requires (e.g., accept, drop, log, etc.).  The
   companion documents of this document define the complex actions
   necessary for IPsec and IKE negotiations.

   As may have been noticed above, the MIB uses recursion in a similar
   manner in several different places.  In particular, the
   spdGroupContentsTable, the spdCompoundFilterTable /
   spdSubfiltersTable combination, and the spdCompoundActionTable /
   spdSubactionsTable combination can reference themselves.

   In the case of the spdGroupContentsTable, a row can indicate a rule
   (i.e., a row in the spdRuleDefinitionTable) or a group (i.e., another
   set of one or more rows in the spdGroupContentsTable).  This way, a
   group can contain a set of rules and sub-groups.  Sub-groups are just
   other groups defined in the spdGroupContentsTable.  There is no
   inherent MIB limit to the depth of nesting of groups.

   The spdCompoundFilterTable / spdSubfiltersTable combination and
   spdCompoundActionTable / spdSubactionsTable combination are designed
   almost identically, with one being for filters and the other for
   actions, respectively.  The following descriptions for the compound
   filter tables can be directly applied to the compound action tables.

   The combination of the tables spdCompoundFilterTable and
   spdSubfiltersTable allow a user to create a set of filters that can
   be referenced from any table as a single filter.  A row in the
   spdCompoundFilterTable has the basic configuration information for
   the compound filter.  The index of spdCompoundFilterTable,
   spdCompFiltname, is also used as a partial index to reference a set
   of ordered rows in the spdSubfiltersTable.  Each row in
   spdSubfiltersTable points to a row in another filter table.  In this
   way, the set of rows in spdSubFiltersTable with a matching
   spdCompFiltName, together with the row in spdCompoundFilterTable
   indexed by spdCompFiltName, create a compound filter.  Note that it
   is possible for a row in the spdSubfiltersTable to point to a row in
   the spdCompoundFilterTable.  This recursion allows the creation of a
   filter set that includes other filter sets within it.  There is no
   inherent MIB limit to the nesting of compound filters within compound
   filters.

5.1.  Usage Tutorial

   In order to use the tables contained in this document, a general
   understanding of firewall processing is helpful.  The processing of
   the security policy database (SPD) involves applying a set of SPD
   rules to an interface on a device.  The given set of rules to apply
   to any given interface is defined within the spdEndpointToGroupTable
   table.  This table maps a given interface to a group of rules.  In
   this table, the interface itself is specified using its assigned
   address.  There is also one group of rules per direction (ingress and
   egress).

5.1.1.  Notational Conventions

   Notes about the following example operations:

   1.  All the example operations in the following section make use of
       default values for all columns not listed.  The operations and
       column values given in the examples are the minimal SNMP Varbinds
       that must be sent to create a row.

   2.  The example operations are formatted such that a row (i.e., the
       table's Entry object) is operated on by using the indexes to that
       row and the column values for that row.

   3.  Below is a generic example of the notation used in the following
       section's examples of this MIB's usage.  This example indicates
       that the MIB row to be set is the row with the index values of
       value1 for index1, and value2 for index2.  Within this row,
       column1 is set to column_value1, and column2 is set to
       column_value2.:

       rowEntry(index1     = value1,
                index2     = value2)
             = (column1        = column_value1,
                column2        = column_value2)

   4.  The below is a specific example of the notation used in the
       following section's examples of this MIB's usage.  This example
       represents the status column of a row in the IP-
       MIB::ipAddressTable table being set to deprecated.  The index
       values for this row are IPv4 and 192.0.2.1.  The example notation
       would look like the following:

       ipAddressEntry(ipAddressAddrType = 1,           -- ipv4
                      ipAddressAddr     = 0xC0000201 ) -- 192.0.2.1
                   = (ipAddressStatus   = 2)           -- deprecated




Baer, et al.                Standards Track                     [Page 6]

RFC 4807              IPsec SPD configuration MIB             March 2007


5.1.2.  Implementing an Example SPD Policy

   As an example, let us define the following administrative policy: On
   the network interface with IP address 192.0.2.1, all traffic from
   host 192.0.2.6 will be dropped and all other traffic will be
   accepted.

   This policy is enforced by setting the values in the MIB to do the
   following:

   o  create a filter for 192.0.2.6

   o  create a rule that connects the 192.0.2.6 filter to a packet drop
      action

   o  create a rule that always accepts packets

   o  group these rules together in the proper order so that the
      192.0.2.6 drop rule is checked first.

   o  connect this group of rules to the 192.0.2.1 interface

   The first step to do this is creating the filter for the IPv4 address
   192.0.2.6:

   SpdIpHeaderFilterEntry(spdIpHeadFiltName = "192.0.2.6")
         = (spdIpHeadFiltType            = 0x80,        -- sourceAddress
            spdIpHeadFiltIPVersion       = 1,           -- IPv4
            spdIpHeadFiltSrcAddressBegin = 0xC0000206,  -- 192.0.2.6
            spdIpHeadFiltSrcAddressEnd   = 0xC0000206,  -- 192.0.2.6
            spdIpHeadFiltRowStatus       = 4)           -- createAndGo

   Next, a rule is created to connect the above "192.0.2.6" filter to an
   action to "drop" the packet, as follows:

   spdRuleDefinitionEntry(spdRuleDefName = "drop from 192.0.2.6")
         = (spdRuleDefFilter             =
                   spdIpHeadFiltType.9.49.57.50.46.48.46.50.46.54,
            spdRuleDefAction             = spdDropAction.0,
            spdRuleDefRowStatus          = 4)           -- createAndGo

   Next, a rule is created that accepts all packets:

   spdRuleDefinitionEntry(spdRuleDefName = "accept all")
         = (spdRuleDefFilter             = spdTrueFilter.0,
            spdRuleDefAction             = spdAcceptAction.0,
            spdRuleDefRowStatus          = 4)           -- createAndGo




Baer, et al.                Standards Track                     [Page 7]

RFC 4807              IPsec SPD configuration MIB             March 2007


   Next, these two rules are grouped together.  Rule groups attached to
   an interface are processed one row at a time.  The rows are processed
   from lowest to highest spdGroupContPriority value.  Because the row
   that references the "accept all" rule should be processed last, it is
   given the higher spdGroupContPriority value.

   SpdGroupContentsEntry(spdGroupContName     = "ingress",
                         spdGroupContPriority = 65535)
        = (spdGroupContComponentName          = "accept all",
           spdGroupContRowStatus              = 4)      -- createAndGo

   SpdGroupContentsEntry(spdGroupContName     = "ingress",
                         spdGroupContPriority = 1000)
        = (spdGroupContComponentName          = "drop from 192.0.2.6",
           spdGroupContRowStatus              = 4)      -- createAndGo

   Finally, this group of rules is connected to the 192.0.2.1 interface
   as follows:

   SpdEndpointToGroupEntry(spdEndGroupDirection = 1,    -- ingress
                           spdEndGroupIdentType = 4,    -- IPv4
                           spdEndGroupAddress   = 0xC0000001)

        = (spdEndGroupName = "ingress",
           spdEndGroupRowStatus = 4)                    -- createAndGo

   This completes the necessary steps to implement the policy.  Once all
   of these rules have been applied, the policy should take effect.

         represents a start date and time and an end date and time.
         For example:

         yyyymmddThhmmss/yyyymmddThhmmss

         Where: yyyy = year     mm = month     dd = day
                  hh = hour     mm = minute    ss = second

         The first 'yyyymmddThhmmss' sub-string indicates the start
         date and time.  The second 'yyyymmddThhmmss' sub-string
         indicates the end date and time.  The character 'T' within
         these sub-strings indicates the beginning of the time
         portion of each sub-string.  The solidus character '/'
         separates the start from the end date and time.  The end
         date and time MUST be subsequent to the start date and
         time.

         There are also two allowed substitutes for a
         'yyyymmddThhmmss' sub-string: one for the start date and
         time, and one for the end date and time.

         If the start date and time are replaced with the string
         'THISANDPRIOR', this sub-string would indicate the current
         date and time and the previous dates and time.

         If the end date and time are replaced with the string
         'THISANDFUTURE', this sub-string would indicate the current
         date and time and the subsequent dates and time.

         Any of the following SHOULD be considered a
         'wrongValue' error:
         - Setting a value with the end date and time earlier than
           or equal to the start date and time.
         - Setting the start date and time to 'THISANDFUTURE'.
         - Setting the end date and time to 'THISANDPRIOR'."

         The value of this object has no effect on whether other
         objects in this conceptual row can be modified.

         This object MUST NOT be set to active until the row to
         which the spdGroupContComponentName points to exists and is
         active.

         If active, this object MUST remain active unless one of the
         following two conditions are met:

         I.  No active row in spdEndpointToGroupTable exists that
             references this row's group (i.e., indicate this row's
             spdGroupContName).

         II. Or at least one other active row in this table has a
             matching spdGroupContName.

         If neither condition is met, an attempt to set this row to
         something other than active MUST result in an
         inconsistentValue error."

    DESCRIPTION
        "The compliance statement for SNMP entities that include
         an IPsec MIB implementation with Endpoint, Rules, and

         When this MIB is implemented with support for read-create,
         then such an implementation can claim full compliance.  Such
         devices can then be both monitored and configured with this
         MIB."

RFC 4807              IPsec SPD configuration MIB             March 2007


7.  Security Considerations

7.1.  Introduction

   This document defines a MIB module used to configure IPsec policy
   services.  Since IPsec provides network security services, all of its
   configuration data (e.g., this entire MIB) SHOULD be as secure or
   more secure than any of the security services IPsec provides.  There
   are two main threats you need to protect against when configuring
   IPsec devices.

   1.  Malicious Configuration: This MIB configures network security
       services.  If an attacker has SET access to any part of this MIB,
       the network security services configured by this MIB SHOULD be
       considered broken.  The network data sent through the associated
       gateway should no longer be considered as protected by IPsec
       (i.e., it is no longer confidential or authenticated).
       Therefore, only the official administrators SHOULD be allowed to
       configure a device.  In other words, administrators' identities
       SHOULD be authenticated and their access rights checked before
       they are allowed to do device configuration.  The support for SET
       operations to the SPD MIB in a non-secure environment, without
       proper protection, will invalidate the security of the network
       traffic affected by the SPD MIB.

   2.  Disclosure of Configuration: In general, malicious parties SHOULD
       NOT be able to read security configuration data while the data is
       in network transit.  An attacker reading the configuration data
       may be able to find misconfigurations in the MIB that enable
       attacks to the network or to the configured node.  Since this
       entire MIB is used for security configuration, it is highly
       RECOMMENDED that only authorized administrators are allowed to
       view data in this MIB.  In particular, malicious users SHOULD be
       prevented from reading SNMP packets containing this MIB's data.
       SNMP GET data SHOULD be encrypted when sent across the network.
       Also, only authorized administrators SHOULD be allowed SNMP GET
       access to any of the MIB objects.

   SNMP versions prior to SNMPv3 do not include adequate security.  Even
   if the network itself is secure (e.g., by using IPsec), earlier
   versions of SNMP have virtually no control as to who on the secure
   network is allowed to access (i.e., read/change/create/delete) the
   objects in this MIB module.

   It is RECOMMENDED that implementers use 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).



Baer, et al.                Standards Track                    [Page 65]

RFC 4807              IPsec SPD configuration MIB             March 2007


   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 GET or SET (change/create/delete) them.

   Therefore, when configuring data in the IPSEC-SPD-MIB, you SHOULD use
   SNMP version 3.  The rest of this discussion assumes the use of
   SNMPv3.  This is a real strength, because it allows administrators
   the ability to load new IPsec configuration on a device and keep the
   conversation private and authenticated under the protection of SNMPv3
   before any IPsec protections are available.  Once initial
   establishment of IPsec configuration on a device has been achieved,
   it would be possible to set up IPsec SAs to then also provide
   security and integrity services to the configuration conversation.
   This may seem redundant at first, but will be shown to have a use for
   added privacy protection below.

7.2.  Protecting against Unauthenticated Access

   The current SNMPv3 User Security Model provides for key-based user
   authentication.  Typically, keys are derived from passwords (but are
   not required to be), and the keys are then used in Hashed Message
   Authentication Code (HMAC) algorithms (currently, MD5 and SHA-1 HMACs
   are defined) to authenticate all SNMP data.  Each SNMP device keeps a
   (configured) list of users and keys.  Under SNMPv3 user keys may be
   updated as often as an administrator cares to have users enter new
   passwords.  But Perfect Forward Secrecy for user keys in SNMPv3 is
   not yet provided by standards track documents, although RFC2786
   defines an experimental method of doing so.

7.3.  Protecting against Involuntary Disclosure

   While sending IPsec configuration data to a Policy Enforcement Point
   (PEP), there are a few critical parameters that MUST NOT be observed
   by third parties.  Specifically, except for public keys, keying
   information MUST NOT be allowed to be observed by third parties.
   This includes IKE Pre-Shared Keys and possibly the private key of a
   public/private key pair for use in a PKI.  Were either of those
   parameters to be known to a third party, they could then impersonate
   the device to other IKE peers.  Aside from those critical parameters,
   policy administrators have an interest in not divulging any of their
   policy configuration.  Any knowledge about a device's configuration
   could help an unfriendly party compromise that device.  SNMPv3 offers
   privacy security services, but at the time this document was written,
   the only standardized encryption algorithm supported by SNMPv3 is the



Baer, et al.                Standards Track                    [Page 66]

RFC 4807              IPsec SPD configuration MIB             March 2007


   DES encryption algorithm.  Support for other (stronger) cryptographic
   algorithms is in the works and may be completed by the time you read
   this.  As of October 2006, there is a stronger standards track
   algorithm: AES [RFC3826].  When configuring the IPsec policy using
   this MIB, policy administrators SHOULD use a privacy security service
   that is at least as strong as the desired IPsec policy, e.g., If an
   administrator were to use this MIB to configure an IPsec connection
   that utilizes a AES algorithms, the SNMP communication configuring
   the connection SHOULD be protected by an algorithm as strong or
   stronger than the AES algorithm.

7.4.  Bootstrapping Your Configuration

   Most vendors will not ship new products with a default SNMPv3 user/
   password pair, but it is possible.  If a device does ship with a
   default user/password pair, policy administrators SHOULD either
   change the password or configure a new user, deleting the default
   user (or, at a minimum, restrict the access of the default user).
   Most SNMPv3 distributions should, hopefully, require an out-of-band
   initialization over a trusted medium, such as a local console
   connection.

8.  IANA Considerations

   Only two IANA considerations exist for this document.  The first is
   just the node number allocation of the IPSEC-SPD-MIB itself within
   the MIB-2 tree.  This is listed in the MIB definition in Section 6.

   The IPSEC-SPD-MIB also allows for extension action MIBs.  Although
   additional actions are not required to use it, the node spdActions is
   allocated as a subtree under which IANA can assign additional
   actions.

   The second IANA consideration is that IANA would be responsible for
   creating a new subregistry for and assigning nodes under the
   spdActions subtree.  This tree should have a prefix of
   iso.org.dod.internet.mgmt.mib-2.spdMIB.spdActions and be listed
   similar to the following:

   Decimal      Name      Description      References
   -------      ----      -----------      ----------

   A documented specification is required in order to assign a number.
   The action and it's meaning can be specified in an RFC or in another
   publicly available reference.  The specification should have
   sufficient detail that interoperability between independent
   implementations is possible.  The product of the IETF or of another
   standards body is acceptable or an assignment can be accepted under
