Abstract

   This document defines a SMIv2 Management Information Base (MIB)
   module for configuring the security policy database of a device
   implementing the IPSec protocol.  The policy-based packet filtering
   and the corresponding execution of actions is of a more general
   nature than for IPsec configuration only, such as for configuration
   of a firewall.  This MIB module is designed with future extensibility
   in mind.  It is thus possible to externally add other packet filters
   and actions to the policy-based packet filtering system defined in
   this document.

1.  Introduction

   This document defines a MIB module for configuration of an IPsec
   security policy database (SPD).  The policy-based packet filtering
   and the corresponding execution of actions is of a more general
   nature than for IPsec configuration only, such as for configuration
   of a firewall.  It is possible to add other packet transforming
   actions to this MIB module if those actions needed to be performed
   conditionally on filtered traffic.

   Companion documents [RFCXXXX], [RFCYYYY] document actions which are
   specific to IPsec and IKE.  No IPsec or IKE specific actions are
   defined within this document.

2.  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].

3.  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 contents of this document are also
   reflected in the "IPsec Configuration Policy Model" (IPCP) [RFC3585].
   This MIB module is a task specific derivation of the IPCP for use
   with SNMPv3.

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

   o  Policies, Groups, Conditions, and some levels of Action are
      generically named.  That is we dropped prefixes like "SA", or
      "ipsec".  This is because we feel that packet classification and
      matching of conditions to actions is more general than IPsec and
      could 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 and their
      restrictions upon the user.  The MIB module offers a compound
      filter object to provide for greater flexibility when creating
      complex filters.

4.  MIB Module Overview

   The MIB module is modularized into several different parts: rules,
   filters, and actions.  The rules section connects endpoints and
   groups of rules together.  This is partially made up of the
   ipspEndpointToGroupTable, ipspGroupContentsTable, and the
   ipspRuleDefinitionTable.  Each row of the ipspRuleDefinitionTable
   connects a filter(s) with an action(s).  It 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 do just that to define IPsec and IKE specific
   actions to be used within this SPD configuration MIB.

   The filter section of the MIB module is composed of all the different
   types of filters in the Policy Model.  It is partially made up of the
   trueFilter, ipspCompoundFilterTable, ipspIpHeaderFilterTable,
   ipspIpOffsetFilterTable, ipspTimeFilterTable, and the
   ipspIpsoHeaderFilterTable.

   The action section of the MIB module contains different action types
   from the Policy Model.  This document contains only the basic actions
   needed for firewall processing (accept, drop, log, ...) that an SPD
   implementation will need.  The companion documents define the IPsec
   and IKE specific actions.

4.1  Usage Tutorial

   In order to make use of the tables contained in this document, a
   general understanding of firewall processing must be first
   understood.  The processing of the security policy database involves
   applying a set of firewall rules to an interface on a device.  The
   given set of rules to apply to any given interface is defined within
   the ipspEndpointToGroupTable table.  This table maps a given
   interface to a group of rules.  The interface itself with in this
   table is specified using its assigned address.  There is also one
   group of rules per direction (inbound and outbound).

4.1.1  Notational conventions

   Notes about the following example operations:

   1.  All of the example operations in the following section make use
       of default values for all columns not listed.  The operations and
       close are the minimal SNMP Varbinds that must be sent.

   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 the that row.  It is left as an
       exercise for the reader to turn these into real SNMP operations
       using real OIDs and real varbinds in a SET PDU.  Example:

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

4.1.2  Implementing an example SPD policy

   For our example, let us define and apply the following policy for all
   incoming traffic on a network interface:

   o  Drop all packets from the host 10.6.6.6.

   o  Accept all other packets.

   To do this, let us call the set of rules (as a group) "incoming" and
   apply them to the incoming traffic for the interface associated with
   the IPv4 address "10.0.0.1".  For these rules, let us apply a policy
   that accepts all traffic except for packets that arrive from a host
   with an IPv4 address of "10.6.6.6".  To achieve this policy, we would
   follow these steps:

   First, we need to create the rules to institute this policy.  To
   accomplish this, first we have to create the filter for the host.  We
   could do this using the following row insertion into the
   spdIpHeaderFilterTable table:

   SpdIpHeaderFilterEntry(spdIpHeadFiltName = "10.6.6.6")
         = (spdIpHeadFiltType            = 0x80,        -- sourceAddress
            spdIpHeadFiltIPVersion       = 1,           -- IPv4
            spdIpHeadFiltSrcAddressBegin = 0x0a060606,
            spdIpHeadFiltSrcAddressEnd   = 0x0a060606,
            spdIpHeadFiltRowStatus       = 5)           -- createAndGo

   Next, we need to bind this filter to an action of "drop" in a new
   rule.  We can do this as follows:

   spdRuleDefinitionEntry(spdRuleDefName = "drop from 10.6.6.6")
         = (spdRuleDefFilter             =
                   spdIpHeadFiltType.8.49.48.46.54.46.54.46.54,
            spdRuleDefAction             = spdDropAction.0,
            spdRuleDefRowStatus          = 5)           -- createAndGo

   We also need a rule to accept all other packets:

   spdRuleDefinitionEntry(spdRuleDefName = "accept all")
         = (spdRuleDefFilter             = spdTrueFilter.0,
            spdRuleDefAction             = spdAcceptAction.0,
            spdRuleDefRowStatus          = 5)           -- createAndGo

   Now, we need to put these two rules into a group.  We will put the
   "accept all" rule at the very end (i.e.  assign it the highest
   priority number), so it is matched last.  Then, at an earlier
   priority (1000), we will insert the "drop from 10.6.6.6" rule.  We
   will do this by putting the rules into the group "incoming".

   SpdGroupContentsEntry(spdGroupContName     = "incoming",
                         spdGroupContPriority = 65535)
        = (spdGroupContComponentName          = "accept all",
           spdGroupContRowStatus              = 5)      -- createAndGo

   SpdGroupContentsEntry(spdGroupContName     = "incoming",
                         spdGroupContPriority = 1000)
        = (spdGroupContComponentName          = "drop from 10.6.6.6",
           spdGroupContRowStatus              = 5)      -- createAndGo

   Finally, we apply this group of rules to our interface:

   SpdEndpointToGroupEntry(spdEndGroupDirection = 1,    -- incoming
                           spdEndGroupIdentType = 4,    -- IPv4
                           spdEndGroupAddress   = 0x0a000001)

        = (spdEndGroupName = "incoming",
           spdEndGroupRowStatus = 5)                    -- createAndGo

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

            ANDed together to produce the result of the entire
            filter.  When processing this filter, it is recommended
            for efficiency reasons that the filter halt processing
            the instant any of the specified tests fail.

            Once a row is 'active', this object's value may not be
            changed unless all the appropriate columns needed by the
            new value to be imposed on this object have been
            appropriately configured.

            The various tests definable in this table are as
            follows:

            sourceAddress:
              - Tests if the source address in the packet lies
                between the spdIpHeadFiltSrcAddressBegin and
                spdIpHeadFiltSrcAddressEnd objects.

                Note that setting these two objects to the same
                address will limit the search to the exact match of
                a single address.  The format and length of the
                address objects are defined by the
                spdIpHeadFiltIPVersion column.

                A row in this table containing a spdIpHeadFiltType
                object with the sourceAddress object bit but without
                the spdIpHeadFiltIPVersion,
                spdIpHeadFiltSrcAddressBegin and
                spdIpHeadFiltSrcAddressEnd objects set will cause
                the spdIpHeadFiltRowStatus object to return the
                notReady state.

            destinationAddress:
              - Tests if the destination address in the packet lies
                between the spdIpHeadFiltDstAddressBegin and
                spdIpHeadFiltDstAddressEnd objects.  Note that
                setting these two objects to the same address will
                limit the search to the exact match of a single
                address.  The format and length of the address
                objects are defined by the spdIpHeadFiltIPVersion
                column.

                A row in this table containing a spdIpHeadFiltType
                object with the destinationAddress object bit but
                without the spdIpHeadFiltIPVersion,
                spdIpHeadFiltDstAddressBegin and

                spdIpHeadFiltDstAddressEnd objects set will cause
                the spdIpHeadFiltRowStatus object to return the
                notReady state.

            sourcePort:
              - Tests if the source port of IP packets using a
                protocol that uses port numbers (at this time, UDP
                or TCP) lies between the spdIpHeadFiltSrcLowPort and
                spdIpHeadFiltSrcHighPort objects.  Note that setting
                these two objects to the same address will limit the
                search to the exact match of a single port.

                A row in this table containing a spdIpHeadFiltType
                object with the sourcePort object bit but without
                the spdIpHeadFiltSrcLowPort, and
                spdIpHeadFiltSrcHighPort objects set will cause the
                spdIpHeadFiltRowStatus object to return the notReady
                state.

            destinationPort:
              - Tests if the source port of IP packets using a
                protocol that uses port numbers (at this time, UDP
                or TCP) lies between the spdIpHeadFiltDstLowPort and
                spdIpHeadFiltDstHighPort objects.  Note that setting
                these two objects to the same address will limit the
                search to the exact match of a single port.

                A row in this table containing a spdIpHeadFiltType
                object with the sourcePort object bit but without
                the spdIpHeadFiltDstLowPort, and
                spdIpHeadFiltDstHighPort objects set will cause the
                spdIpHeadFiltRowStatus object to return the notReady
                state.

            protocol:
              - Tests to see if the packet being processed is for
                the given protocol type.

                A row in this table containing a spdIpHeadFiltType
                object with the protocol object bit but without the

                spdIpHeadFiltRowStatus object to return the notReady
                state.

            ipv6FlowLabel:
              - Tests to see if the packet being processed contains
                an ipv6 Flow Label which matches the value in the
             ipfIPv6FlowLabel object.  Setting this bit mandates
             that for the packet to match the filter, it must be
             an IPv6 packet.

                A row in this table containing a spdIpHeadFiltType
                object with the ipv6FlowLabel object bit but without
                the ipfIPv6FlowLabel object set will cause the
                spdIpHeadFiltRowStatus object to return the notReady
                state."

6.  Security Considerations

6.1  Introduction

   This document defines a MIB module used to configure IPsec policy
   services.  Since IPsec provides security services it is important
   that the IPsec configuration data be at least as protected as the
   IPsec provided security service.  There are two main threats you need
   to thwart when configuring IPsec devices.

   1.  Malicious Configuration: 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 IPSP MIB in
       a non-secure environment, without proper protection, can have a
       negative effect on the security of the network traffic affected
       by the IPSP MIB.

   2.  Disclosure of Configuration:  Malicious parties should not be
       able to read configuration data while the data is in network
       transit.  Any knowledge about a device's IPsec policy
       configuration could help an unfriendly party compromise that
       device and/or the network(s) it protects.  It is thus important
       to control even GET 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.

   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.

6.2  Protecting against in-authentic 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 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 is not yet provided by standards track documents,
   although RFC2786 defines an experimental method of doing so.

6.3  Protecting against involuntary disclosure

   While sending IPsec configuration data to a PEP, there are a few
   critical parameters which MUST NOT be observed by third parties.
   These include 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
   your 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 DES encryption algorithm.  Support for
   other (stronger) cryptographic algorithms is in the works and may be
   done as you read this.  Policy administrators SHOULD use a privacy
   security service to configure their IPsec policy which is at least as
   strong as the desired IPsec policy.  E.G., it is unwise to configure
   IPsec parameters implementing 3DES algorithms while only protecting
   that conversation with single DES.

6.4  Bootstrapping your configuration

   Hopefully vendors will not ship new products with a default SNMPv3
   user/password pair, but it is possible.  Most SNMPv3 distributions
   should hopefully require an out-of-band initialization over a trusted
   medium, such as a local console connection.
