Abstract 
 
   This document presents an object-oriented model of IPsec policy 
   designed to: 
   o    facilitate agreement about the content and semantics of IPsec 
        policy 
   o    enable derivations of task-specific representations of IPsec 
        policy such as storage schema, distribution representations, 
        and policy specification languages used to configure IPsec-
        enabled endpoints 
   The schema described in this document models the IKE phase one 
   parameters as described in [IKE] and the IKE phase two parameters 
   for the IPsec Domain of Interpretation as described in [COMP, ESP, 
   AH, DOI].  It is based upon the core policy classes as defined in 
   the Policy Core Information Model (PCIM) [PCIM].

Internet Draft     IPsec Configuration Policy Model         March 2001 
 
 
1. Introduction 
    
   Internet Protocol security (IPsec) policy may assume a variety of 
   forms as it travels from storage to distribution point to decision 
   point.  At each step, it needs to be represented in a way that is 
   convenient for the current task.  For example, the policy could 
   exist as, but is not limited to: 
    
   o   a Lightweight Directory Access Protocol (LDAP) [LDAP] schema in 
       a directory 
   o   an on-the-wire representation over a transport protocol like the 
       Common Object Policy Service (COPS) [COPS, COPSPR] 
   o   a text-based policy specification language [SPSL] suitable for 
       editing by an administrator 
   o   an Extensible Markup Language (XML) document 
    
   Each of these task-specific representations should be derived from a 
   canonical representation that precisely specifies the content and 
   semantics of the IPsec policy.  The purpose of this document is to 
   abstract IPsec policy into a task-independent representation that is 
   not constrained by any particular task-dependent representation. 
    
   This document is organized as follows: 
    
   o   Section 2 provides a quick introduction to the Unified Modeling 
       Language (UML) graphical notation conventions used in this 
       document. 
    
   o   Section 3 provides the inheritance hierarchy which that describes 
       where the IPsec policy classes fit into the policy class 
       hierarchy already defined by PCIM. the Policy Core Information Model 
       (PCIM). 
    
   o   The remainder of the document describes the classes which that make up 
       the IPsec policy model. 
    
   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 [KEYWORDS]. 
    
2. UML Conventions 
    
   For this document, a UML static class diagram was chosen as the 
   canonical representation for the IPsec policy model.  The reason 
   behind this decision is that UML provides a graphical, task-
   independent way to model systems.  A treatise on the graphical 
   notation used in UML is beyond the scope of this paper.  However, 
   given the use of ASCII drawing for UML static class diagrams, a 
   description of the notational conventions used in this document is 
   in order: 
    
   o   Boxes represent classes, with class names in brackets ([]) 
       representing a virtual an abstract class.

   o   A line that terminates with an arrow (<, >, ^, v) denotes 
       inheritance.  The arrow always points to the parent class.  
       Inheritance can also be called generalization or specialization 
       (depending upon the reference point).  A base class is a 
       generalization of a derived class, and a derived class is a 
       specialization of a base class. 
   o   Associations are used to model a relationship between two 
       classes.  Classes that share an association are connected using 
       a line.
       There are two  A special kinds kind of associations - aggregations and
       compositions.  Both model association is also used:  an 
       aggregation.  An aggregation models a whole-part relationship 
       between two classes.  Associations, and therefore aggregations and
       compositions, aggregations, 
       can also be modeled as classes. 
   o   A line that begins with a an "o" denotes aggregation.  Aggregation 
       denotes containment in which the contained class and the 
       containing class have independent lifetimes. 
   o   A line that begins with an "x" denotes composition.  Composition
       denotes containment in which the contained class and the
       contianing class have coincident lifetimes.
   o   Next to a line representing an association appears a
       multiplicity.  Multiplicities 
       cardinality.  Cardinalities indicate the constraints on the 
       number of objects object instances in
       the relationship.  The multiplicity may be:
       - a range in the form "lower bound..upper set of relationships.  Every 
       association instance has a single set of references.  The 
       cardinality indicates the number of instances that may refer to 
       a given object instance.  The cardinality may be: 
       - a range in the form "lower bound..upper bound" indicating the 
       minimum and maximum number of objects.  
       - a number that indicates the exact number of objects. 
       - an asterisk indicating any number of objects, including zero.  
       Using an asterisk is shorthand for 0..n. 
       - the letter n indicating from 1 to many.  Using the letter n is 
       shorthand for 1..n. 
   o   A class that has an association may have a "w" next to the line 
       representing the association.  This is called a weak association 
       and is discussed in [PCIM]. 
 

   It should be noted that the UML static class diagram presented is a 
   conceptual view of IPsec policy designed to aid in understanding.  
   It does not necessarily get translated class for class into another 
   representation.  For example, an LDAP implementation may flatten out 
   the representation to fewer classes (because of the inefficiency of 
   following references). 
 
3. IPsec Policy Model Inheritance Heirarchy Hierarchy 
    
   Like PCIM from which it is derived, the IPsec Configuration Policy 
   Model derives from and uses classes defined in the DMTF Common 
   Information Model (CIM).  The following diagram tree represents the 
   inheritance hierarchy and how for the IPsec policy model classes and how 
   they fit into PCIM.

Jason PCIM and the other DMTF models (see Appendices for 
   descriptions of classes that are not being introduced as part of 
   IPsec model).  CIM classes that are not used as a superclass from 
   which to derive new classes but are only referenced are not included 
   this inheritance hierarchy, but are included in the appropriate 
   appendix.

4.1. The Class IPsecPolicyGroup 
    
   The class IPsecPolicyGroup serves as a container of either other 
   IPsecPolicyGroups or a set of IKERules and a set of IPsecRules.
   Rules contained within an IPsecPolicyGroup MUST have a unique
   Priority value.  The 
   class definition for IPsecPolicyGroup is as follows: 
    
   NAME         IPsecPolicyGroup 
   DESCRIPTION  Either a set of IPsecPolicyGroups or a set of IKERules 
                and a set of IPsecRules.

   may follow all of IPsecPolicyGroupInPolicyGroup associations and 
   create one policy group which is simply a set of all of the IKE

4.2. The Property IKERuleOverridePoint

   This property specifies the rule priority at which the policy author
   is willing to allow IKERule insertions by Class SARule 
    
   The class SARule serves as a local administrator.
   For example, base class for IKERule and IPsecRule.  
   Even though the IT department may define the policy on class is concrete, it MUST not be instantiated.  It 
   defines a company-
   wide basis, but allow groups or individuals to insert rules into the
   policy to override defaults.  Rules are ordered in decreasing order
   of their priority (i.e., higher priorities come first).  The
   override common connection point specifies that if rules are inserted, they are to be
   inserted before all rules equal for associations to or less than conditions and 
   actions for both types of rules.  Through its derivation from 
   PolicyRule, an SARule (and therefore IKERule and IPsecRule) also has 
   the override
   priority value.

   For example, assume that PolicyRuleValidityPeriod association. 
    
   An SARule inherits the property Priority from PolicyRule.  Since 
   there is a group G1 with IKE rules as
   follows:

   G1 = { Rule A (priority 50),
          Rule B (priority 25),
          Rule C (priority 15) }

   The IKE override value need for G1 is 20.  Now assume that a local
   administrator wants to insert a set an unambiguous ordering of IKE rules {Rule D, Rule E}
   where Rule D has a higher priority than Rule E.  The new rules will
   be added before rules in G1 with priority equal to or less than 20.
   So, when evaluating rules, the order of evaluation would be A, B, D,
   E, C.  Note that the an IPsec 
   system, all SARules contained within an IPsecPolicyGroup must have 
   unique priority of the rules in override set are

   negotiation is willing stopped. Note that this only applies to allow new IKE phase 
   1 negotiations and has no effect on either renegotiation or refresh 
   operations with peers for which an established SA already exists.  
    
   Before proceeding with a phase 2 negotiation, the LimitNegotiation 
   property of the IPsecRule insertions is first checked to determine if the 
   negotiation role indicated for the rule matches that of the current 
   negotiation (Initiator, Responder, or Either).  Note that this limit 
   applies only to new phase 2 negotiations.  It is ignored when an 
   attempt is made to refresh an expiring SA (either side can initiate 
   a refresh operation).  The IKE system can determine that the 
   negotiation is a refresh operation by checking to see if the 
   selector information matches that of an existing SA. If 
   LimitNegotiation does not match and the selector corresponds to a local
                administrator.

   The IKE service of a security endpoint may have multiple identities 
   for use in different situations.  The combination of the interface 
   (represented by the IPProtocolEndpoint), the identity type (as 
   specified in the IKEAction) and the IdentityContexts specifies a 
   unique identity.

   The IdentityContexts property specifies the context to select the 
   relevant IKE identity to be used during the further IKEAction.  A 
   context may be a VPN name or other identifier for selecting the 
   appropriate identity for use on the protected IPProtocolEndpoint. 
    
   IdentityContexts is an array of strings.  The multiple values in the 
   array are ORed together in evaluating the IdentityContexts.  Each 
   value in the array may be the composition of multiple context names.  
   So, a single value may be a single context name (e.g., 
   "CompanyXVPN") or it may be combination of contexts.  When an array 
   value is a composition, the individual values are ANDed together for 
   evaluation purposes and the syntax is: 
    
        <ContextName>[&&<ContextName>]*  
   
   where the individual context names appear in alphabetical order 
   (according to the collating sequence for UCS-2).  So, for example, 
   the values "CompanyXVPN", "CompanyYVPN&&TopSecret", 
   "CompanyZVPN&&Confidential" means that, for the appropriate 
   IPProtocolEndpoint and IdentityType, the contexts are matched if the 
   identity specifies "CompanyXVPN" or "CompanyYVPN&&TopSecret" or 
   "CompanyZVPN&&Confidential". 
    
   The property is defined as follows:

   The property SequenceNumber specifies, for a given rule, ActionOrder specifies the order relative position of this

   fallback SAAction is successfully applied, then subsequent fallback
   SAActions should be ignored. PolicyRule.  
   The property is defined ActionOrder MUST be unique so as follows:

   order.  In addition, the

   VALUE        Lower valued fallback SAActions actions in an SARule are attempted first. executed as 
   follows. 
    
   For an initiator, if there is more than one action in the rule, the 
   additional actions are 'backup' actions in the event that the first 
   action is not able to be completed successfully.  They are tried in 
   the ActionOrder until the list is exhausted or one completes 
   successfully.  For example, an IKE initiator may have several 
   IKEActions for the same SACondition. The initiator will try all 
   IKEActions in the order defined by ActionOrder.  I.e. it will 
   possibly try several phases 1 possibly with different modes (main 
   mode then aggressive mode) and/or with possibly multiple IKE peers. 
    
   For a responder, there can be more than one action in the rule, this 
   provides alternative actions depending on the received proposals.  
   For example, the same IKERule may be used to handle aggressive mode 
   and main mode negotiations with different actions.  The first 
   appropriate action in the list of attempt actions is used by the responder. 
    
   The property is defined as follows:

                precedence).  The merging order of ContainedActions two SAActions with 
                the same

5.1. The Class SACondition 
    
   The class SACondition defines the preconditions conditions of rules for IKE and 
   IPsec negotiations.  Conditions are associated with policy rules via 
   the SAConditionInRule aggregation. It is used as an anchor point to 
   associate various types of filters with policy rules via the
   FilterOfSACondition association. It also defines whether Credentials 
   can be accepted for a particular policy rule via the 
   AcceptCredentialsFrom association.

   Associated objects represent components of the condition that may or 
   may not apply at a given rule evaluation.  For example, an 
   AcceptCredentialsFrom evaluation is only performed when a credential 
   is available to be evaluated against the list of trusted credential 
   management services.  Similarly, a PeerIDPayloadFilterEntry may only 
   be evaluated when an IDPayload value is available to compared with 
   the filter.  Condition components that do not have corresponding 
   values with which to evaluate are evaluated as TRUE unless the 
   protocol has completed without providing the required information. 
    
   The class definition for SACondition is as follows:

   uses the various tables that contain information about IKE peers as 
   well as the configuration for specifying security associations that 
   are started automatically.  The information in the PeerGateway, 
   PeerIdentityTable and related classes is necessary to completely 
   specify the policies. 
    
   An interface (represented by an IPProtocolEndpoint) has an 
   IKEService that provides the negotiation services for that 
   interface.  That service MAY also have a list of security 
   associations for that are automatically started at the time the IKE 
   service is initialized. 
    
   The IKEService also has a set of identities that it may use in 
   negotiations with its peers.  Those identities are associated with 
   the interfaces (or collections of interfaces).

                IdentityContexts 
    
8.6.1. The Property IdentityType 
    
   The property IdentityType is an enumeration that specifies the type 
   of the IdentityValue.  The property is defined as follows: 
    
   NAME         IdentityType 
   DESCRIPTION  IdentityType is the type of the IdentityValue. 
   SYNTAX       unsigned 8-bit integer 
   VALUE        The enumeration values are specified in [DOI] section 
                4.6.2.1. 
    
8.6.2. The Property IdentityValue 
    
   The property Identity specifies Value contains a string encoding of 
   the Identity payload.  For IKEIdentity instances that are address 
   types, the IdentityValue string value may be omitted and the 
   associated IPProtocolEndpoint or appropriate member of the 
   Collection of endpoints is used.  The property is defined as 
   follows: 
    
   NAME         IdentityValue 
   DESCRIPTION  IdentityValue contains a string encoding of the 
                Identity payload. 
   SYNTAX       string 
    
8.6.3. The Property IdentityContexts 
    
   The IdentityContexts property is used to constrain the use of 
   IKEIdentity instances to match that specified in the 
   IKERule.IdentityContexts.  The IdentityContexts are formatted as 
   policy roles and role combinations [PCIM].  Each value represents 
   one context or context combination.  Since this is a multi-valued 
   property, more than one context or combination of contexts can be 
   associated with a single IKEIdentity.  Each value is a string of the 
   form:        <ContextName>[&&<ContextName>]* 
   where the individual context names appear in alphabetical order 
   (according to the collating sequence for UCS-2). If one or more 
   values in the IKERule.IdentityContexts array match one or more 
   IKEIdentity.IdentityContexts then the identity's context matches.  
   (That is, each value of the IdentityContext array is an ORed 
   condition.)  In combination with the address of the 
   IPProtocolEndpoint and IKEAction.UseIKEIdentityType, there SHOULD be 
   1 and only 1 IKEIdentity.  The property is defined as follows: 
    
   NAME         IdentityContexts 
   DESCRIPTION  The IKE service of a security endpoint may have 
                multiple identities for use in different situations. 
                The combination of the interface (represented by 
                the IPProtocolEndpoint), the identity type (as

8.16.1. The Reference Antecedent 
    
   The property Antecedent is inherited from ElementAsUser and is 
   overridden to refer to an IPProtocolEndpoint instance.  The [0..1] 
   cardinality indicates that an IKEIdentity instance MUST be 
   associated with at most one IPProtocolEndpoint instance. 
    
8.16.2. The Reference Dependent 
    
   The property Dependent is inherited from ElementAsUser and is 
   overridden to refer to an IKEIdentity instance.  The [0..n] 
   cardinality indicates that an IPProtocolEndpoint instance may be 
   associated with zero or more IKEIdentity instances. 
 
8.17. The Association Class CollectionHasLocalIKEIdentity 
    
   The class CollectionHasLocalIKEIdentity associates a Collection of  
   IPProtocolEndpoint instances with a set of IKEIdentity instances 
   that may be used in negotiating SAs for endpoints in the collection. 
   An IKEIdentity MUST be associated with either an IPProtocolEndpoint 
   using the EndpointHasLocalIKEIdentity association or with a 
   collection of IKEIdentity instances using this association.  The 
   class definition for CollectionHasLocalIKEIdentity is as follows: 
    
   NAME         CollectionHasLocalIKEIdentity 
   DESCRIPTION  CollectionHasLocalIKEIdentity associates a collection 
                of IPProtocolEndpoint instances with a set of

9. Security Considerations 
    
   This document describes a schema for IPsec policy.  It does not 
   detail security requirements for storage or delivery of said schema.  
   Storage and delivery security requirements should be detailed in a 
   comprehensive security policy architecture document.
