Abstract
-
This document defines a Structure of Management Information Version 2 (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 described in this document are of a more general nature than for IPsec configuration alone, such as for configuration of a firewall. This MIB module is designed to be extensible with other enterprise or standards-based defined packet filters and actions.

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 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:
- 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.
- 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.
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:
- 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.
- 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.
- 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)- 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
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:
- create a filter for 192.0.2.6
- create a rule that connects the 192.0.2.6 filter to a packet drop action
- create a rule that always accepts packets
- group these rules together in the proper order so that the 192.0.2.6 drop rule is checked first.
- 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) -- createAndGoNext, 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) -- createAndGoNext, a rule is created that accepts all packets:
spdRuleDefinitionEntry(spdRuleDefName = "accept all")
= (spdRuleDefFilter = spdTrueFilter.0,
spdRuleDefAction = spdAcceptAction.0,
spdRuleDefRowStatus = 4) -- createAndGo
-
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) -- createAndGoFinally, 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.

-
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'."

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.
- 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.
- 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).
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
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 the advice of a "designated expert". (contact IANA for the current expert)
