Expires March 13, 2017 [Page 11] Internet-Draft SACM Information Model September 2016 1. Introduction The SACM Information Model (IM) serves multiple purposes: o to ensure interoperability between SACM data models that are used as transport encodings, o to provide a standardized set of Information Elements - the SACM Vocabulary - to enable the exchange of content vital to automated security posture assessment, and o to enable secure information sharing in a scalable and extensible fashion in order to support the tasks conducted by SACM components. A complete set of requirements imposed on the IM can be found in [I-D.ietf-sacm-requirements]. The SACM IM is intended to be used for standardized data exchange between SACM components (data in motion). Nevertheless, the Information Elements (IE) and their relationships defined in this document can be leveraged to create and align corresponding data models for data at rest. The information model expresses, for example, target endpoint (TE) attributes, guidance, and evaluation results. The corresponding Information Elements are consumed and produced by SACM components as they carry out tasks. The primary tasks that this information model supports (on data, control, and management plane) are: o TE Discovery o TE Characterization o TE Classification o Collection o Evaluation o Information Sharing o SACM Component Discovery o SACM Component Authentication o SACM Component Authorization Waltermire, et al. Expires March 13, 2017 [Page 12] Internet-Draft SACM Information Model September 2016 o SACM Component Registration These tasks are defined in [I-D.ietf-sacm-terminology]. 2. Conventions used in this document 2.1. Requirements Language 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]. 2.2. Information Element Examples The notation used to define the SACM Information Elements (IEs) is based on a customized version of the IPFIX information model syntax [RFC7012] which is described in Figure 2. However, there are several examples presented throughout the document that use a simplified pseudo-code to illustrate the basic structure. It should be noted that while they include actual names of subjects and attributes as well as values, they are not intended to influence how corresponding SACM IEs should be defined in Section 7. The examples are provided for demonstration purposes only. 3. Information Elements The IEs defined in this document comprise the building blocks by which all SACM content is composed. They are consumed and provided by SACM components on the data plane. Every Information Element has a unique label: its name. Every type of IE defined by the SACM IM is registered as a type at the IANA registry. The Integer Index of the IANA SMI number tables can be used by SACM data models. 3.1. Context of Information Elements The IEs in this information model represent information related to assets in the following areas (based on the use cases described in [RFC7632]): o Endpoint Management o Software Inventory Management o Hardware Inventory Management o Configuration Management o Vulnerability Management Waltermire, et al. Expires March 13, 2017 [Page 13] Internet-Draft SACM Information Model September 2016 3.2. Extensibility of Information Elements A SACM data model based on this information model MAY include additional information elements that are not defined here. The labels of additional Information Elements included in different SACM data models MUST NOT conflict with the labels of the Information Elements defined by this information model, and the names of additional Information Elements MUST NOT conflict with each other or across multiple data models. In order to avoid naming conflicts, the labels of additional IEs SHOULD be prefixed to avoid collisions across extensions. The prefix MUST include an organizational identifier and therefore, for example, MAY be an IANA enterprise number, a (partial) name space URI, or an organization name abbreviation. 4. Structure of Information Elements There are two basic types of IEs: o Attributes: an instance of an attribute type is the simplest IE structure comprised of a unique attribute name and an attribute value. o Subjects: a subject is a richer structure that has a unique subject name and one or more attributes or subjects. In essence, instances of a subject type are defined (and differentiated) by the attribute values and subjects associated with it. hostname = "arbutus" coordinates = ( latitude = N27.99619, longitude = E86.92761 ) Figure 1: Example instance of an attribute and subject. In general, every piece of information that enables security posture assessment or further enriches the quality of the assessment process can be associated with metadata. In the SACM IM, metadata is represented by specific subjects and is bundled with other attributes or subjects to provide additional information about them. The IM explicitly defines two kinds of metadata: o Metadata focusing on the data origin (the SACM component that provides the information to the SACM domain) Waltermire, et al. Expires March 13, 2017 [Page 14] Internet-Draft SACM Information Model September 2016 o Metadata focusing on the data source (the target endpoint that is assessed) Metadata can also include relationships that refer to other associated IEs (or SACM content in general) by using referencing labels that have to be included in the metadata of the associated IE. Subjects can be nested and the SACM IM allows for circular or recursive nesting. The association of IEs via nesting results in a tree-like structure wherein subjects compose the root and intermediary nodes and attributes the leaves of the tree. This semantic structure does not impose a specific structure on SACM data models regarding data in motion or data repository schemata for data at rest. The SACM IM provides two conceptual top-level subjects that are used to ensure a homogeneous structure for SACM content and its associated metadata: SACM statements and SACM content-elements. Every set of IEs that is provided by a SACM component must provide the information contained in these two subjects although it is up to the implementer whether or not the subjects are explicitly defined in a data model. The notation the SACM IM is defined in is based on a modified version of the IP Information Flow Export (IPFIX) Information Model syntax described in Section 2.1 of [RFC7012]. The customized syntax used by the SACM IM is defined below in Figure 2. elementId (required): The numeric identifier of the Information Element. It is used for the compact identification of an Information Element. If this identifier is used without an enterpriseID, then the elementId must be unique, and the description of allowed values is administrated by IANA. The value "TBD" may be used during development of the information model until an elementId is assigned by IANA and filled in at publication time. enterpriseId (optional): Enterprises may wish to define Information Elements without registering them with IANA, for example, for enterprise-internal purposes. For such Information Elements, the elementId is Waltermire, et al. Expires March 13, 2017 [Page 15] Internet-Draft SACM Information Model September 2016 not sufficient when used outside the enterprise. If specifications of enterprise- specific Information Elements are made public and/or if enterprise-specific identifiers are used by SACM components outside the enterprise, then the enterprise-specific identifier MUST be made globally unique by combining it with an enterprise identifier. Valid values for the enterpriseId are defined by IANA as Structure of Management Information (SMI) network management private enterprise numbers. name (required): A unique and meaningful name for the Information Element. dataType (required): There are two kinds of datatypes: simple and structured. Attributes are defined using simple datatypes and subjects are defined using structured datatypes. The contents of the datatype field will be either a reference to one of the simple datatypes listed in Section 5.1, or the specification of structured datatype as defined in Section 5.2. status (required): The status of the specification of the Information Element. Allowed values are "current" and "deprecated". All newly defined Information Elements have "current" status. The process for moving Information Elements to the "deprecated" status is TBD. description (required): Describes the meaning of the Information Element, how it is derived, conditions for its use, etc. structure (optional): A parsable property that provides details about the definition of Waltermire, et al. Expires March 13, 2017 [Page 16] Internet-Draft SACM Information Model September 2016 structured Information Elements as described in Section 5.2. references (optional): Identifies other RFCs or documents outside the IETF which provide additional information or context about the Information Element. Figure 2: Information Element Specification Template 4.1. Information Element Naming Convention SACM Information Elements must adhere to the following naming conventions. o Names SHOULD be descriptive o Names MUST be unique within the SACM registry. Enterprise- specific names SHOULD be prefixed with a Private Enterprise Number [PEN]. o Names MUST start with lowercase letters unless it begins with a Private Enterprise Number o Composed names MUST use capital letters for the first letter of each part 4.2. SACM Content Elements Every piece of information that is provided by a SACM component is always associated with a set of metadata, for example, the timestamp at which this set of information was produced (e.g. by a collection task) or what target endpoint this set of information is about (e.g. the data-source or a target endpoint identifier, respectively). The subject that associates content IE with content-metadata IE is called a content-element. Content metadata can also include relationships that express associations with other content-elements. Waltermire, et al. Expires March 13, 2017 [Page 17] Internet-Draft SACM Information Model September 2016 content-element = ( content-metadata = ( collection-timestamp = 146193322, data-source = fb02e551-7101-4e68-8dec-1fde6bd10981 ), hostname = "arbutus", coordinates = ( latitude = N27.99619, longitude = E86.92761 ) ) Figure 3: Example set of IEs associated with a timestamp and a target endpoint label. 4.3. SACM Statements One or more SACM content elements are bundled in a SACM statement. In contrast to content-metadata, statement-metadata focuses on the providing SACM component instead of the target endpoint that the content is about. The only content-specific metadata included in the SACM statement is the content-type IE. Therefore, multiple content- elements that share the same statement metadata and are of the same content-type can be included in a single SACM statement. A SACM statement functions similar to an envelope or a header. Its purpose is to enable the tracking of the origin of data inside a SACM domain and more importantly to enable the mitigation of conflicting information that may originate from different SACM components. How a consuming SACM component actually deals with conflicting information is out-of-scope of the SACM IM. Semantically, the term statement implies that the SACM content provided by a SACM component might not be correct in every context, but rather is the result of a best- effort to produce correct information. Waltermire, et al.

Relationships An IE can be associated with another IE, e.g. a user-name attribute can be associated with a content-authorization subject. These references are expressed via the relationships subject, which can be included in a corresponding content-metadata subject. The relationships subject includes a list of one or more references. The SACM IM does not enforce a SACM domain to use unique identifiers as Waltermire, et al. Expires March 13, 2017 [Page 20] Internet-Draft SACM Information Model September 2016 references. Therefore, there are at least two ways to reference another o The value of a reference represents a specific content-label that is unique in a SACM domain (and has to be included in the corresponding content-element metadata in order to be referenced), or o The reference is a subject that includes an appropriate number of IEs in order to identify the referenced content-element by its actual content. It is recommended to provide unique identifiers in a SACM domain and the SACM IM provides a corresponding naming-convention as a reference in Section 4.1. The alternative highlighted above summarizes a valid approach that does not require unique identifiers and is similar to the approach of referencing target endpoints via identifying attributes included in a characterization record. content-element = ( content-metadata = ( collection-timestamp = 1461934031, te-label = fb02e551-7101-4e68-8dec-1fde6bd10981 relationships = ( associated-with-user-account = f3d70ef4-7e18-42af-a894-8955ba87c95d ) ), hostname = "arbutus" ) content-element = ( content-metadata = ( content-label = f3d70ef4-7e18-42af-a894-8955ba87c95d ), user-account = ( username = romeo authentication = local ) ) Figure 6: Example instance of a content-element subject associated with another subject via its content metadata. Waltermire, et al. Expires March 13, 2017 [Page 21] Internet-Draft SACM Information Model September 2016 4.5. Event Event subjects provide a structure to represent the change of IE values that was detected by a collection task at a specific point of time. It is mandatory to include the new values and the collection timestamp in an event subject and it is recommended to include the past values and a collection timestamp that were replaced by the new IE values. Every event can also be associated with a subject- specific event-timestamp and a lastseen-timestamp that might differ from the corresponding collection-timestamps. If these are omitted the collection-timestamp that is included in the content-metadata subject is used instead. sacm-statement = ( statement-metadata = ( publish-timestamp = 1461934031, data-origin = 24e67957-3d31-4878-8892-da2b35e121c2, content-type = event ), event = ( event-attributes = ( event-name = "host-name change", content-element = ( content-metadata = ( collection-timestamp = 146193322, data-source = fb02e551-7101-4e68-8dec-1fde6bd10981, event-component = past-state ), hostname = "arbutus" ), content-element = ( content-metadata = ( collection-timestamp = 146195723, data-source = fb02e551-7101-4e68-8dec-1fde6bd10981, event-component = current-state ), hostname = "lilac" ) ) ) Figure 7: Example of a SACM statement containing an event. Waltermire, et al. Expires March 13, 2017 [Page 22] Internet-Draft SACM Information Model September 2016 4.6. Categories Categories are special IEs that enable to refer to multiple types of IE via just one name. Therefore, they are similar to a type-choice. A prominent example of a category is network-address. Network- address is a category that every kind of network address is associated with, e.g. mac-address, ipv4-address, ipv6-address, or typed-network-address. If a subject includes network-address as one of its components, any of the category members are valid to be used in its place. Another prominent example is EndpointIdentifier. Some IEs can be used to identify (and over time re-recognize) target endpoints - those are associated with the category endpoint-identifier. 5. Abstract Data Types This section describes the set of valid abstract data types that can be used for the specification of the SACM Information Elements in Section 7. SACM currently supports two classes of datatypes that can be used to define Information Elements. o Simple: Datatypes that are atomic and are used to define the type of data represented by an attribute Information Element. o Structured: Datatypes that can be used to define the type of data represented by a subject Information Element. Note that further abstract data types may be specified by future extensions of the SACM information model. 5.1. Simple Datatypes 5.1.1. IPFIX Datatypes To facilitate the use of existing work, SACM supports the following abstract data types defined in Section 3 of [RFC7012]. o unsigned8, unsigned16, unsigned32, unsigned64 o signed8, signed16, signed32, signed64 o float32, float64 o boolean o macAddress Waltermire, et al. Expires March 13, 2017 [Page 23] Internet-Draft SACM Information Model September 2016 o octetArray o string o dateTimeSeconds, dateTimeMilliseconds, dateTimeMicroseconds, dateTimeNanoSeconds o ipv4Address, ipv6Address 5.2. Structured Datatypes 5.2.1. List Datatypes SACM defines the following abstract list data types that are used to represent the structured data associated with subjects. o list: indicates that the Information Element order is not significant but MAY be preserved. o orderedList: indicates that Information Element order is significant and MUST be preserved. The notation for defining a SACM structured datatype is based on regular expressions, which are composed of the keywords "list" or "orderedList" and an Information Element expression. IE expressions use some of the regular expression syntax and operators, but the terms in the expression are the names of defined Information Elements instead of character classes. The syntax for defining list and orderedList datatypes is described below, using BNF: -> ("list"|"orderedList") "(" ")" -> ? ( ("," | "|") ?)* -> "*" | "+" | "?" | ( "(" ("," )? ")" ) Figure 8: Syntax for Defining List Datatypes As seen above, multiple occurences of an Information Element may be present in a structured datatype. The cardinality of an Information Element within a structured Information Element definition is defined by the following operators: Waltermire, et al. Expires March 13, 2017 [Page 24] Internet-Draft SACM Information Model September 2016 * - zero or more occurrences + - one or more occurrences ? - zero or one occurrence (m,n) - between m and n occurrences Figure 9: Specifying Cardinality for Structured Datatypes The absence of a cardinality operator implies one mandatory occurrence of the Information Element. Below is an example of a structured Information Element definition. personInfo = list(firstName, middleNames?, lastName) firstName = string middleNames = orderedList(middleName+) middleName = string lastName = string As an example, consider the name "John Ronald Reuel Tolkien". Below are instances of this name, structured according to the personInfo definition. personInfo = (firstName="John", middleNames(middleName="Ronald", middleName="Reuel"), lastName="Tolkien") personInfo = (middleNames(middleName="Ronald", middleName=" Reuel"), lastName="Tolkien", firstName="John") The instance below is not legal with respect to the definition of personInfo because the order in middleNames is not preserved. personInfo = (firstName="John", middleNames(middleName=" Reuel", middleName="Ronald"), lastName="Tolkien") Figure 10: Example of Defining a Structured List Datatype 5.2.2. Enumeration Datatype SACM defines the following abstract enumeration datatype that is used to represent the restriction of an attribute value to a set of values. Waltermire, et al. Expires March 13, 2017 [Page 25] Internet-Draft SACM Information Model September 2016 name, hex-value, description -> -> ";" ";" -> [0-9a-zA-Z]+ -> 0x[0-9a-fA-F]+ -> [0-9a-zA-Z\.\,]+ Figure 11: Syntax for Defining an Enumeration Datatype Below is an example of a structured Information Element definition for an enumeration. Red ; 0x1 ; The color is red. Orange ; 0x2 ; The color is orange. Yellow ; 0x3 ; The color is yellow. Green ; 0x4 ; The color is green. ... Figure 12: Example of Defining a Structured Enumeration Datatype 6. Information Model Assets In order to represent the Information Elements related to the areas listed in Section 3.1, the information model defines the information needs (or metadata about those information needs) related to following types of assets which are defined in [I-D.ietf-sacm-terminology] (and included below for convenience) which are of interest to SACM. Specifically: o Endpoint o Software Component o Hardware Component o Identity o Guidance o Evaluation Results The following figure shows the make up of an Endpoint asset which contains zero or more hardware components and zero or more software components each of which may have zero or more instances running an endpoint at any given time as well as zero or more identities that act on behalf of the endpoint when interfacing with other endpoints, tools, or services. An endpoint may also contain other endpoints in the case of a virtualized environment. Waltermire, et al.

Asset As defined in [RFC4949], an asset is a system resource that is (a) required to be protected by an information system's security policy, (b) intended to be protected by a countermeasure, or (c) required for a system's mission. In the scope of SACM, an asset can be composed of other assets. Examples of Assets include: Endpoints, Software, Guidance, or Identity. Furthermore, an asset is not necessarily owned by an organization. 6.2. Endpoint From [RFC5209], an endpoint is any computing device that can be connected to a network. Such devices normally are associated with a particular link layer address before joining the network and potentially an IP address once on the network. This includes: laptops, desktops, servers, cell phones, or any device that may have an IP address. To further clarify, an endpoint is any physical or virtual device that may have a network address. Note that, network infrastructure Waltermire, et al. Expires March 13, 2017 [Page 27] Internet-Draft SACM Information Model September 2016 devices (e.g. switches, routers, firewalls), which fit the definition, are also considered to be endpoints within this document. Physical endpoints are always composites that are composed of hardware components and software components. Virtual endpoints are composed entirely of software components and rely on software components that provide functions equivalent to hardware components. The SACM architecture differentiates two essential categories of endpoints: Endpoints whose security posture is intended to be assessed (target endpoints) and endpoints that are specifically excluded from endpoint posture assessment (excluded endpoints). 6.3. Hardware Component Hardware components are the distinguishable physical components that compose an endpoint. The composition of an endpoint can be changed over time by adding or removing hardware components. In essence, every physical endpoint is potentially a composite of multiple hardware components, typically resulting in a hierarchical composition of hardware components. The composition of hardware components is based on interconnects provided by specific hardware types (e.g. mainboard is a hardware type that provides local busses as an interconnect). In general, a hardware component can be distinguished by its serial number. Examples of a hardware components include: motherboards, network interfaces, graphics cards, hard drives, etc. 6.4. Software Component A software package installed on an endpoint (including the operating system) as well as a unique serial number if present (e.g. a text editor associated with a unique license key). It should be noted that this includes both benign and harmful software packages. Examples of benign software components include: applications, patches, operating system kernel, boot loader, firmware, code embedded on a webpage, etc. Examples of malicious software components include: malware, trojans, viruses, etc. 6.4.1. Software Instance A running instance of the software component (e.g. on a multi-user system, one logged-in user has one instance of a text editor running and another logged-in user has another instance of the same text editor running, or on a single-user system, a user could have multiple independent instances of the same text editor running). Waltermire, et al. Expires March 13, 2017 [Page 28] Internet-Draft SACM Information Model September 2016 6.5. Identity Any mechanism that can be used to identify an asset during an authentication process. Examples include usernames, user and device certificates, etc. Note, that this is different than the identity of assets in the context of designation as described in Section 11.1. 6.6. Guidance Guidance is input instructions to processes and tasks, such as collection or evaluation. Guidance influences the behavior of a SACM component and is considered content of the management plane. Guidance can be manually or automatically generated or provided. Typically, the tasks that provide guidance to SACM components have a low-frequency and tend to be sporadic. A prominent example of guidance are target endpoint profiles,but guidance can have many forms, including: Configuration, e.g. a SACM component's name, or a CMDB's IPv6 address. Profiles, e.g. a set of expected states for network behavior associated with target endpoints employed by specific users. Policies, e.g. an interval to refresh the registration of a SACM component, or a list of required capabilities for SACM components in a specific location. 6.6.1. Collection Guidance A collector may need guidance to govern what it collects and when. Collection Guidance provides instructions for a Collector that specifies which endpoint attributes to collect, when to collect them, and how to collect them. Collection Guidance is composed of Target Endpoint Attribute Guidance, Frequency Guidance, and Method Guidance. o Target Endpoint Attribute Guidance: Set of endpoint attributes that are supposed to be collected from a target endpoint. The definition of the set of endpoint attributes is typically based on an endpoint characterization record. o Frequency Guidance: Specifies when endpoint attributes are to be collected. o Method Guidance: Indicates how endpoint attributes are to be collected. Waltermire, et al. Expires March 13, 2017 [Page 29] Internet-Draft SACM Information Model September 2016 6.6.2. Evaluation Guidance An evaluator typically needs guidance to govern what it considers to be a good or bad security posture. Evaluation Guidance provides instructions for an Evaluator that specifies which endpoint attributes to evaluate, the desired state of those endpoint attributes, and any special requirements that enable an Evaluator to determine if the endpoint attributes can be used in the evaluation (e.g. freshness of data, how it was collected, etc.). Evaluation Guidance is composed of Target Endpoint Attribute Guidance, Expected Endpoint Attribute Value Guidance, and Frequency Guidance. o Target Endpoint Attribute Guidance: Set of target endpoint attributes that are supposed to be used in an evaluation as well as any requirements on the endpoint attributes. The definition of the set of endpoint attributes is typically based on an endpoint characterization record. o Expected Endpoint Attribute Value Guidance: The expected values of the endpoint attributes described in the Target Endpoint Attribute Guidance. o Frequency Guidance: Specifies when endpoint attributes are to be evaluated. o Method Guidance: Indicates how endpoint attributes are to be collected. 6.6.3. Classification Guidance A SACM Component carrying out the Target Endpoint Classification Task may need guidance on how to classify an endpoint. Specifically, how to associate endpoint classes with a specific target endpoint characterization record. Target Endpoint Classes function as guidance for collection, evaluation, remediation and security posture assessment in general. Classification Guidance is composed of Target Endpoint Attribute Guidance and Class Guidance. o Target Endpoint Attribute Guidance: Set of target endpoint attributes that are supposed to be used to identify the endpoint characterization record. o Class Guidance: A list of target endpoint classes that are to be associated with the identified target endpoint characterization record. Waltermire, et al. Expires March 13, 2017 [Page 30] Internet-Draft SACM Information Model September 2016 6.6.4. Storage Guidance An SACM Component typically needs guidance to govern what information it should store and where. Storage Guidance provides instructions for a SACM Component that specifies which security automation information should be stored, for how long, and on which endpoint. Storage Guidance is composed of Target Endpoint Attribute Guidance, Expected Security Automation Information Guidance, and Retention Guidance. o Target Endpoint Attribute Guidance: Set of target endpoint attributes that are supposed to be used to identify the endpoint where the security automation information is to be stored. o Expected Security Automation Information Guidance: The security automation information that is expected to be stored (guidance, collected posture attributes, results, etc.). o Retention Guidance: Specifies how long the security automation information should be stored. 6.6.5. Evaluation Results Evaluation Results are the output of comparing the actual state of an endpoint against the expected state of an endpoint. In addition to the actual results of the comparison, Evaluation Results should include the Evaluation Guidance and actual target endpoint attributes values used to perform the evaluation. 7.

Acknowledgements Many of the specifications in this document have been developed in a public-private partnership with vendors and end-users. The hard work Waltermire, et al. Expires March 13, 2017 [Page 143] Internet-Draft SACM Information Model September 2016 of the SCAP community is appreciated in advancing these efforts to their current level of adoption. Over the course of developing the initial draft, Brant Cheikes, Matt Hansbury, Daniel Haynes, Scott Pope, Charles Schmidt, and Steve Venema have contributed text to many sections of this document. 9. IANA Considerations This document specifies an initial set of Information Elements for SACM in Section 7. An Internet Assigned Numbers Authority (IANA) registry will be created and populated with the Information Elements in Section 7. New assignments for SACM Information Elements will be administered by IANA through Expert Review [RFC2434]. The designated experts MUST check the requested Information Elements for completeness and accuracy of the submission with respect to the template and requirements expressed in Section 4 and Section 4.1. Requests for Information Elements that duplicate the functionality of existing Information Elements SHOULD be declined. The smallest available Information Element identifier SHOULD be assigned to a new Information Element. The definition of new Information Elements MUST be published using a well-established and persistent publication medium. 10. Security Considerations Posture Assessments need to be performed in a safe and secure manner. In that regard, there are multiple aspects of security that apply to the communications between components as well as the capabilities themselves. This information model only contains an initial listing of items that need to be considered with respect to security and will need to be augmented as the model continues to be developed. Security considerations include: Authentication: Every SACM Component and asset needs to be able to identify itself and verify the identity of other SACM Components and assets. Confidentiality: Communications between SACM Components need to be protected from eavesdropping or unauthorized collection. Some communications between SACM Components and assets may need to be protected as well. Integrity: The information exchanged between SACM Components needs to be protected from modification. Some exchanges between assets and SACM Components will also have this requirement. Waltermire, et al. Expires March 13, 2017 [Page 144] Internet-Draft SACM Information Model September 2016 Restricted Access: Access to the information collected, evaluated, reported, and stored should only be viewable and consumable to authenticated and authorized entities. Considerations with respect to the operational aspects of collection, evaluation, and storage security automation information can be found in Section 11. Considerations concerning the privacy of security automation information can be found in Section 12. 11. Operational Considerations The following sections outline a series of operational considerations for SACM deployments within an organization. This section may be expanded to include other considerations as the WG gains additional operational experience with SACM deployments and extending the information model. 11.1. Endpoint Designation In order to successfully carry out endpoint posture assessment, it is necessary to be able to identify the endpoints on a network and track the changes to them over time. Specifically, enabling SACM Components to: o Tell whether two endpoint attribute assertions concern the same endpoint o Respond to compliance measurements, for example by reporting, remediating, and quarantining (SACM does not specify these responses, but SACM exists to enable them). Ideally, every endpoint would be identified by a unique identifier present on the endpoint, but, this is complicated due to different factors such as the variety of endpoints on a network, the ability of tools to reliably access such an identifer, and the ability of tools to correlate disparate identifiers. As a result, it is necessary for an endpoint to be identified by a set of attributes that uniquely identify it on a network. The set of attributes that uniquely identify an endpoint on a network will likely vary by organization; however, there are a number of properties to consider when selecting identifying attributes as some are better suited for identification purposes than others. Multiplicity: Is the attribute typically associated with a single endpoint or with multiple endpoints? If the attribute is Waltermire, et al. Expires March 13, 2017 [Page 145] Internet-Draft SACM Information Model September 2016 associated with a single endpoint, it is better for identifying an endpoint on a network. Persistence: How likely is the attribute to change? Does it never change? Does it only change when the endpoint is reprovisioned? Does it only change due to an event? Does it change on an ad-hoc and often unpredictable basis? Does it constantly change? The less likely it is for an attribute to change over time, the better it is for identifying an endpoint on a network. Immutability: How difficult is it to change the attribute? Is the attribute hardware rooted and never changes? Can the attribute be changed by a user/process with the appropriate access? Can the attribute be changed without controlled access. The less likely an attribute is to change over time, the better chance it will be usable to identify an endpoint over time. Verifiable: Can the attribute be corroborated? Can the attribute be externally verified with source authentication? Can the attribute be externally verified without source authentication? Is it impossible to externally verify the attribute. Attributes that can be externally verified are more likely to be accurate and are better for identifying endpoints on a network. With that said, requiring SACM Components and end users to constantly refer to a set of attributes to identify an endpoint, is particularly burdensome. As a result, SACM supports the concept of a target endpoint label which associates an identifier (unique to a SACM domain) with the set of attributes used by an organization to identify endpoints on a network. Once defined for an endpoint, the target endpoint label can be used in place of the set of identifying attributes. 11.2. Timestamp Accuracy An organization will likely have different collectors deployed across the network that will be configured to collect posture attributes on varying frequencies (periodic, ad-hoc, event-driven, on endpoint, off endpoint, etc.). Some collectors will detect changes as soon as they occur whereas others will detect them at a later point during a periodic scan or when an event has triggered the collection of posture attributes. Furthermore, some changes will be detected on the endpoint and others will be observed off of the endpoint. As a result of these differences, the accuracy of the timestamp associated with the collected information will vary. For example, if a Waltermire, et al. Expires March 13, 2017 [Page 146] Internet-Draft SACM Information Model September 2016 collector is only running once every 12 hours, the change probably happened at some point in time prior to the scan and the timestamp is likely not accurate. Due to this, it is important for system administrators to determine if the accuracy of a timestamp is good enough for their intended purposes. 12. Privacy Considerations In the IETF, there are privacy concerns with respect to endpoint identity and monitoring. This is especially true when the activity on an endpoint can be linked to a particular person. For example, by correlating endpoint attributes such as usernames, certificates, etc. with browser activity, it may be possible to gain insight in to user behavior and trends beyond what is required to carry out endpoint posture assessments. In the hands of the wrong person, this information could be used to negatively influence a user's behavior or to plan attacks against the organization's infrastructure. As a result, SACM data models should incorporate a mechanism by which an organization can designate which endpoint attributes are considered sensitive with respect to privacy. This will allow SACM Components to handle endpoint attributes in a manner consistent with the organization's privacy policies. Furthermore, organization's should put the proper mechanism in place to ensure endpoint attributes are protected when transmitted, stored, and accessed to ensure only authorized parties are granted access. It should also be noted that some of this is often mitigated by organizational policies that require a user of an organization's network to consent to some level of monitoring in return for access to the network and other resources. The information that is monitored and collected will vary by organization and further highlights the need for a mechanism by which an organization can specify what constitutes privacy sensitive information for them. 13.

Expires March 13, 2017 [Page 148] Internet-Draft SACM Information Model September 2016 Appendix A. Change Log A.1. Changes in Revision 01 Added some proposed normative text. For provenance: Added a class "Method" Added the produced-using relationship between an AVP and a method Added the produced-by relationship between a Guidance and a SACM Component Added the hosted-by relationship between a SACM Component and an Endpoint asserted-by and summarized-by have been renamed to produced-by. "User" is now "Account". If a user has different credentials, SACM cannot know that they belong to the same user. But, per Kim W, many organizations do have accounts that associate credentials. The multiplicity of the based-on relationships has been corrected. More relationships now have labels, per UML convention. The diagram no longer has causal arrow. They had become redundant and were nonstandard and clutter. Renamed "credential" to "identity", following industry usage. A credential includes proof, such as a key or password. A username or a distinguished name is called an "identity". Removed Session, because an endpoint's network activity is not SACM's initial focus Removed Authorization, for the same reason Added many-to-many relationship between Hardware Component and Endpoint, for clarity Added many-to-many relationship between Software Component and Endpoint, for clarity Added "contains" relationship between Network Interface and Network Interface Waltermire, et al. Expires March 13, 2017 [Page 149] Internet-Draft SACM Information Model September 2016 Removed relationship between Network Interface and Account. The endpoint knows the identity it used to gain network access. The PDP also knows that. But they probably do not know the account. Added relationship between Network Interface and Identity. The endpoint and the PDP will typically know the identity. Made identity-to-account a many-to-one relationship. A.2. Changes in Revision 02 Added Section Identifying Attributes. Split the figure into Figure Model of Endpoint and Figure Information Elements. Added Figure Information Elements Take 2, proposing a triple-store model. Some editorial cleanup A.3. Changes in Revision 03 Moved Appendix A.1, Appendix A.2, and Mapping to SACM Use Cases into the Appendix. Added a reference to it in Section 1 Added the Section 4 section. Provided notes for the type of information we need to add in this section. Added the Section 6 section. Moved sections on Endpoint, Hardware Component, Software Component, Hardware Instance, and Software Instance there. Provided notes for the type of information we need to add in this section. Removed the Provenance of Information Section. SACM is not going to solve provenance rather give organizations enough information to figure it out. Updated references to the Endpoint Security Posture Assessment: Enterprise Use Cases document to reflect that it was published as an RFC. Fixed the formatting of a few figures. Included references to [RFC3580] where RADIUS is mentioned. Waltermire, et al. Expires March 13, 2017 [Page 150] Internet-Draft SACM Information Model September 2016 A.4. Changes in Revision 04 Integrated the IPFIX [RFC7012] syntax into Section 4. Converted many of the existing SACM Information Elements to the IPFIX syntax. Included existing IPFIX Information Elements and datatypes that could likely be reused for SACM in Section 7 and Section 4 respectively. Removed the sections related to reports as described in https://github.com/sacmwg/draft-ietf-sacm-information-model/ issues/30. Cleaned up other text throughout the document. A.5. Changes in Revision 05 Merged proposed changes from the I-D IM into the WG IM (https://github.com/sacmwg/draft-ietf-sacm-information-model/ issues/41). Fixed some formatting warnings. Removed a duplicate IE and added a few IE datatypes that were missing. A.6. Changes in Revision 06 Clarified that the SACM statement and content-element subjects are conceptual and that they do not need to be explicitly defined in a data model as long as the necessary information is provided. Updated the IPFIX syntax used to define Information Elements. There are still a couple of open issues that need to be resolved. Updated some of the Information Elements contained in Section 7 to use the revised IPFIX syntax. The rest of the Information Elements will be converted in a later revision. Performed various clean-up and refactoring in Sections 6 and 7. Still need to go through Section 8. Removed appendices that were not referenced in the body of the draft. The text from them is still available in previous revisions of this document if needed. Waltermire, et al. Expires March 13, 2017 [Page 151] Internet-Draft SACM Information Model September 2016 A.7. Changes in Revision 07 Made various changes to the IPFIX syntax based on discussions at the IETF 96 Meeting. Changes included the addition of a structure property to the IE specification template, the creation of an enumeration datatype, and the specification of an IE naming convention. Provided text to define Collection Guidance, Evaluation Guidance, Classification Guidance, Storage Guidance, and Evaluation Results. Included additional IEs related to software, configuration, and the vulnerability assessment scenario. Added text for the IANA considerations, security considerations, operational considerations, and privacy considerations sections. Performed various other editorial changes and clean-up.
