Introduction This document defines a MIB module for monitoring IP Flow Information Export (IPFIX) Devices including Exporters and Collectors. The full configuration of the IPFIX Metering Process is out of the scope this MIB. 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]. Dietz, et al. draft-ietf-ipfix-mib-05.txt [Page 4] Internet-Draft IPFIX MIB November 2008 2. IPFIX Documents Overview The IPFIX protocol provides network administrators with access to IP Flow information. The architecture for the export of measured IP Flow information out of an IPFIX Exporting Process to a Collecting Process is defined in [I-D.ietf-ipfix-architecture], per the requirements defined in [RFC3917]. The protocol document [RFC5101] specifies how IPFIX Data Record and Templates are carried via a congestion-aware transport protocol from IPFIX Exporting Processes to IPFIX Collecting Process. IPFIX has a formal description of IPFIX Information Elements, their name, type and additional semantic information, as specified in [RFC5102]. Finally [I-D.ietf-ipfix-as] describes what type of applications can use the IPFIX protocol and how they can use the information provided. It furthermore shows how the IPFIX framework relates to other architectures and frameworks. It is assumed that Flow metering, export and collection is performed according to the IPFIX architecture defined in [I-D.ietf-ipfix-architecture]. The monitored configuration parameters of the export and collection of Flow Templates and Records is modeled according to [RFC5101]. Packet selection and filtering methods that may be optionally used by the IPFIX Metering Process are not considered in this MIB module. They are defined in the Packet Sampling (PSAMP) framework [I-D.ietf-psamp-framework] and sampling techniques [I-D.ietf-psamp-sample-tech] documents. Nevertheless the entry point for those methods [I-D.ietf-psamp-mib] is given within this MIB module since PSAMP export protocol [I-D.ietf-psamp-protocol] is based on the IPFIX protocol. Dietz, et al. draft-ietf-ipfix-mib-05.txt [Page 5] Internet-Draft IPFIX MIB November 2008 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]. Dietz, et al. draft-ietf-ipfix-mib-05.txt [Page 6] Internet-Draft IPFIX MIB November 2008 4. Terminology The definitions of the basic terms like IP Traffic Flow, Exporting Process, Collecting Process, Observation Points, etc. can be found in the IPFIX protocol document [RFC5101]. Dietz, et al. draft-ietf-ipfix-mib-05.txt [Page 7] Internet-Draft IPFIX MIB November 2008 5. Structure of the IPFIX MIB The IPFIX MIB consists of six main tables, the Transport Session table, the Template table and the corresponding Template Definition table, the Export table, the Metering Process table and the Observation Point table. Since the IPFIX architecture [I-D.ietf-ipfix-architecture] foresees the possibility of using filtering and/or sampling functions to reduce the data volume the MIB provides the basic objects for these functions with the Selector Table and a subtree for hooking standard filtering and sampling functions. All remaining objects contain statistical values for the different tables contained in the MIB. Finally an entry point for extensions of the IPFIX MIB is given that can be used e.g. for the PSAMP MIB [I-D.ietf-psamp-mib]. The following subsections describe all tables in the IPFIX MIB module. 5.1. Textual Convention IpfixFunctionAvailabilty In conjunction with the Selector Functions described in section 5.9 the textual convention IpfixFunctionAvailabilty is defined in the MIB. It MUST be used within all Selector Functions to indicate if a standard function is currently available at the Device or not. The Select All function described in the same section below is always available. 5.2. The Transport Session Table The Transport Session is the basis of the MIB. The Transport Session table (ipfixTransportSessionTable) contains all Transport Sessions between Exporter and Collector. The table specifies the layer 4 protocol of the Transport Session and, depending on the protocol, further parameters for the Transport Session. In case of UDP and TCP these are the source and destination address as well as the source and destination port. For SCTP the table contains the SCTP Assoc Id which is the index for the SCTP association in the SCTP MIB [RFC3873]. The mode of operation, i.e. if the Transport Session is used for collecting or exporting is given in the ipfixTransportSessionMode object. Further on it contains the configured refresh parameters for Templates and Option Templates that are used across unreliable connections as UDP. Finally a status of the Transport Session is given in the table. To illustrate the use of the above tables let us assume the following scenario: We have an Exporter on IP address 192.0.2.22 and a Dietz, et al. draft-ietf-ipfix-mib-05.txt [Page 8] Internet-Draft IPFIX MIB November 2008 Collector on IP address 192.0.2.37. The Exporter uses TCP to export Templates and Data Records. The same Exporter also exports to a Collector with the IP address of 192.0.2.44. This would lead to the following Transport Session Table on the Exporter: ipfixTransportSessionTable (2) | +- ipfixTransportSessionEntry (1) | +- index (5) (ipfixTransportSessionIndex) | +- ipfixTrasportSessionIndex (1) = 5 | +- ipfixTransportSessionProtocol (2) = 6 (TCP) | +- ipfixTransportSessionAddressType (3) = 1 (ipv4) | +- ipfixTransportSessionSourceAddress (4) = 192.0.2.22 | +- ipfixTransportSessionDestinationAddress (5) = 192.0.2.37 | +- ipfixTransportSessionSourcePort (6) = 7653 | +- ipfixTransportSessionDestinationPort (7) = 4739 | +- ipfixTransportSessionSctpAssocId (8) = 0 | +- ipfixTransportSessionMode (9) = exporting(1) | +- ipfixTransportSessionTemplateRefreshTimeout (10) = 0 | +- ipfixTransportSessionOptionTemplateRefreshTimeout (11) = 0 | +- ipfixTransportSessionTemplateRefreshPacket (12) = 0 | +- ipfixTransportSessionOptionTemplateRefreshPacket (13) = 0 | +- ipfixTransportSessionStatus (14) = 2 (active) . . . +- index (11) (ipfixTransportSessionIndex) +- ipfixTrasportSessionIndex (1) = 11 +- ipfixTransportSessionProtocol (2) = 17 (UDP) +- ipfixTransportSessionAddressType (3) = 1 (ipv4) +- ipfixTransportSessionSourceAddress (4) = 192.0.2.22 +- ipfixTransportSessionDestinationAddress (5) = 192.0.2.44 +- ipfixTransportSessionSourcePort (6) = 14287 +- ipfixTransportSessionDestinationPort (7) = 4739 +- ipfixTransportSessionSctpAssocId (8) = 0 +- ipfixTransportSessionMode (9) = exporting(1) +- ipfixTransportSessionTemplateRefreshTimeout (10) = 100 +- ipfixTransportSessionOptionTemplateRefreshTimeout (11) | = 100 +- ipfixTransportSessionTemplateRefreshPacket (12) = 10 +- ipfixTransportSessionOptionTemplateRefreshPacket (13) = 10 +- ipfixTransportSessionStatus (14) = 2 (active) The values in brackets are the OID numbers. The Collectors would then have the same entry except that the index would most likely differ. Dietz, et al. draft-ietf-ipfix-mib-05.txt [Page 9] Internet-Draft IPFIX MIB November 2008 5.3. The Template Table The Template table lists all Templates (including Option Templates) that are sent (by an Exporter) or received (by a Collector). The (Option) Templates are unique per Transport Session which also gives the mode (Exporter or Collector) and Observation Domain, thus the table is indexed by o the Transport Session Index (ipfixTransportSessionIndex) o and the Observation Domain Id (ipfixObservationDomainId). It contains the Set Id and an Access Time denoting the time when the (Option) Template was last sent or received. To resume the above example the Exporter may want to export a Template and an Option Template for each Transport Session defined above. This leads to the following Template Table defining Template and Option Template: Dietz, et al. draft-ietf-ipfix-mib-05.txt [Page 10] Internet-Draft IPFIX MIB November 2008 ipfixTemplateTable (3) | +- ipfixTemplateEntry (1) | +- index (5) (ipfixTransportSessionIndex) | +- index (3) (ipfixObservationDomainId) | + index (257) (ipfixTemplateId) | | +- ipfixObservationDomainId (1) = 3 | | +- ipfixTemplateId (2) = 257 | | +- ipfixTemplateSetId (3) = 2 | | +- ipfixTemplateAccessTime (4) | | = 2008-7-1,12:49:11.2,+2:0 | | | + index (264) (ipfixTemplateId) | +- ipfixObservationDomainId (1) = 3 | +- ipfixTemplateId (2) = 264 | +- ipfixTemplateSetId (3) = 3 | +- ipfixTemplateAccessTime (4) . = 2008-7-1,12:47:04.8,+2:0 . . . +- index (11) (ipfixTransportSessionIndex) +- index (3) (ipfixObservationDomainId) + index (273) (ipfixTemplateId) | +- ipfixObservationDomainId (1) = 3 | +- ipfixTemplateId (2) = 273 | +- ipfixTemplateSetId (3) = 2 | +- ipfixTemplateAccessTime (4) | = 2008-7-1,12:49:11.2,+2:0 | + index (289) (ipfixTemplateId) +- ipfixObservationDomainId (1) = 3 +- ipfixTemplateId (2) = 289 +- ipfixTemplateSetId (3) = 3 +- ipfixTemplateAccessTime (4) = 2008-7-1,12:47:04.8,+2:0 We assume that the Transport Session that is stored with index 5 in the Transport Session table of the Exporter is stored with index 17 in the Transport Session table of the (corresponding) Collector. Then, the Template table would look as follows: Dietz, et al. draft-ietf-ipfix-mib-05.txt [Page 11] Internet-Draft IPFIX MIB November 2008 ipfixTemplateTable (3) | +- ipfixTemplateEntry (1) | +- index (17) (ipfixTransportSessionIndex) +- index (3) (ipfixObservationDomainId) + index (257) (ipfixTemplateId) | +- ipfixObservationDomainId (1) = 3 | +- ipfixTemplateId (2) = 257 | +- ipfixTemplateSetId (3) = 2 | +- ipfixTemplateAccessTime (4) | = 2008-7-1,12:49:11.8,+2:0 | + index (264) (ipfixTemplateId) +- ipfixObservationDomainId (1) = 3 +- ipfixTemplateId (2) = 264 +- ipfixTemplateSetId (3) = 3 +- ipfixTemplateAccessTime (4) = 2008-7-1,12:47:05.3,+2:0 The table on the second Collector would be analog to the one shown above. 5.4. The Template Definition Table The Template Definition table lists all the Information Elements contained in a Template or Option Template. Therefore it has the same indexes as the corresponding Template table plus the Template Id. Its own index denotes the order of the Information Element inside the Template if necessary. Besides the Information Element Id and the length of the encoded value the table contains the enterprise number for enterprise specific Information Elements and flags for each Information Element. The flags indicate if the Information Element is used for scoping or as a Flow key. To resume the above example again the Exporter may want to export the octets received and dropped at the Observation Point since the last export of these values. In addition it exports the start and end time of the flow relative to the timestamp contained in the IPFIX header. This leads to the following Template Definition table on the Exporter: Dietz, et al. draft-ietf-ipfix-mib-05.txt [Page 12] Internet-Draft IPFIX MIB November 2008 ipfixTemplateDefinitionTable (4) | +- ipfixTemplateDefinitionEntry (1) | +- index (5) (ipfixTransportSessionIndex) +- index (3) (ipfixObservationDomainId) + index (257) (ipfixTemplateId) +- index (1) (ipfixTemplateDefinitionIndex) | +- ipfixTemplateDefinitionIndex (1) = 1 | +- ipfixTemplateDefinitionIeId (2) = 158 | | (flowStartDeltaMicroseconds) | +- ipfixTemplateDefinitionIeLength (3) = 4 | +- ipfixTemplateDefinitionEnterprise (4) = 0 | +- ipfixTemplateDefinitionFlags (5) = 0 | +- index (2) (ipfixTemplateDefinitionIndex) | +- ipfixTemplateDefinitionIndex (1) = 2 | +- ipfixTemplateDefinitionIeId (2) = 159 | | (flowStartDeltaMicroseconds) | +- ipfixTemplateDefinitionIeLength (3) = 4 | +- ipfixTemplateDefinitionEnterprise (4) = 0 | +- ipfixTemplateDefinitionFlags (5) = 0 | +- index (3) (ipfixTemplateDefinitionIndex) | +- ipfixTemplateDefinitionIndex (1) = 3 | +- ipfixTemplateDefinitionIeId (2) = 1 | | (octetDeltaCount) | +- ipfixTemplateDefinitionIeLength (3) = 8 | +- ipfixTemplateDefinitionEnterprise (4) = 0 | +- ipfixTemplateDefinitionFlags (5) = 0 | +- index (4) (ipfixTemplateDefinitionIndex) +- ipfixTemplateDefinitionIndex (1) = 4 +- ipfixTemplateDefinitionIeId (2) = 132 | (droppedOctetDeltaCount) +- ipfixTemplateDefinitionIeLength (3) = 8 +- ipfixTemplateDefinitionEnterprise (5) = 0 +- ipfixTemplateDefinitionFlags (4) = 0 The corresponding table entry on the collector is the same except that it would have another ipfixTransportSessionIndex, e.g. 17 to as in the previous example. 5.5. The Export Table On Exporters, the Export table (ipfixExportTable) can be used to support features like failover, load-balancing, duplicate export to several Collectors etc. The table has 5 indexes that link an entry Dietz, et al. draft-ietf-ipfix-mib-05.txt [Page 13] Internet-Draft IPFIX MIB November 2008 with o the Metering Process table (ipfixMeteringProcessCacheId, see below), o the Exported Template table (ipfixObservationDomainId and ipfixTemplateId) o and the Transport Session table (ipfixTransportSessionIndex). Those entries with the same ipfixExportIndex, the same ipfixMeteringProcessCacheId and the same ipfixObservationDomainId define a Transport Session group. The member type for each group member describes its functionality. All Transport Sessions referenced in this table MUST have the ipfixTransportSessionMode exporting(1). If the Exporter does not use Transport Session grouping then each ipfixExportIndex contains a single ipfixMeteringProcessCacheId and thus a singe Transport Session (ipfixTransportSessionIndex) and this session MUST have the member type primary(1). For failover a Transport Session group can contain one Transport Session with member type "primary" and several Transport Sessions with type "secondary". Entries with other member types are not allowed for that type of group. For load-balancing or parallel export all Transport Sessions in the group MUST have the same member type either "loadBalancing" or "duplicate". The algorithms used for failover or load-balancing are out of the scope of this document. To continue the example we assume that the Exporter uses the two connections shown in the examples above as the primary export for a session protected by a secondary backup connection. The Exporter then has the following entries in the ipfixExportTable: Dietz, et al. draft-ietf-ipfix-mib-05.txt [Page 14] Internet-Draft IPFIX MIB November 2008 ipfixExportTable (5) | +- ipfixExportEntry (1) | +- index (7) (ipfixExportIndex) | +- index (9) (ipfixMeteringProcessCacheId) | +- index (3) (ipfixObservationDomainId) | +- index (257) (ipfixTemplateId) | | +- index (5) (ipfixTransportSessionIndex) | | +- ipfixExportIndex (1) = 7 | | +- ipfixExportMemberType (2) = 1 (primary) | | | +- index (273) (ipfixTemplateId) | +- index (11) (ipfixTransportSessionIndex) | +- ipfixExportIndex (1) = 7 | +- ipfixExportMemberType (2) = 2 (secondary) | +- index (8) (ipfixExportIndex) +- index (9) (ipfixMeteringProcessCacheId) +- index (3) (ipfixObservationDomainId) +- index (264) (ipfixTemplateId) | +- index (5) (ipfixTransportSessionIndex) | +- ipfixExportIndex (1) = 8 | +- ipfixExportMemberType (2) = 2 (secondary) +- index (289) (ipfixTemplateId) +- index (11) (ipfixTransportSessionIndex) +- ipfixExportIndex (1) = 7 +- ipfixExportMemberType (2) = 1 (primary) The example shows that the Exporter uses the Metering Cache 9 explained below to export IPFIX Records for the Templates 257, 273, 264 and 289. Templates 257 and 264 are exported to Transport Session 5 and Templates 273 and 289 are exported to Transport Session 11. If we assume that Templates 257 and 264 are identical then the Collector that receives Transport Session 11 is a backup for the Collector of Transport Session 5. 5.6. The Metering Process Table The Metering Process as defined in [RFC5101] consists of a set of function. Maintaining the Flow Records is one of them. This function is responsible for passing the Flow Records to the Exporting Process and also for detecting Flow expiration. The Flow Records that are maintained by the Metering Process can be grouped by the Observation Points they are observed. The instance that maintains such a group of Flow Records is a kind of cache. For this reason the Metering Process table (ipfixMeteringProcessTable) is grouped by cache IDs (ipfixMeteringProcessCacheId). Each cache can be Dietz, et al. draft-ietf-ipfix-mib-05.txt [Page 15] Internet-Draft IPFIX MIB November 2008 maintained by a separate instance of the Metering Process which is represented by the Metering Process ID (ipfixMeteringProcessId). To specify the Observation Point(s) where the Flow Records are gathered the ipfixObservationPointGroupReference may contain an ipfixObservationPointGroupId from the Observation Point table (ipfixObservationPointTable) described in the next section. If an Observation Point cannot be given the ipfixObservationPointGroupReference MUST be zero(0). The timeouts (ipfixMeteringProcessCacheActiveTimeout and ipfixMeteringProcessCacheInactiveTimeout) specify when Flow Records are passed to the Exporting Process. ipfixMeteringProcessTable(6) | +- ipfixMeteringProcessEntry(1) | +- index(9) (ipfixMeteringProcessCacheId) +- ipfixMeteringProcessCacheId(1) = 9 +- ipfixMeteringProcessId(2) = 287 +- ipfixObservationPointGroupReference(3) = 17 +- ipfixMeteringProcessCacheActiveTimeout(4) = 100 +- ipfixMeteringProcessCacheInactiveTimeout(5) = 100 5.7. The Observation Point Table The Observation Point Table (ipfixObservationPointTable) groups Observation Points with the ipfixObservationPointGroupId. Each entry contains a reference to the ENTITY MIB [RFC4133]. The objects in the ENTITY MIB denote the Observation Point. In addition a direction can be given to render more specific which Flow to monitor. ipfixObservationPointTable(7) | +- ipfixObservationPointEntry(1) | +- index(17) (ipfixObservationPointGroupId) +- index(1) (ipfixObservationPointIndex) | +- ipfixObservationPointGroupId(1) = 17 | +- ipfixObservationPointIndex(2) = 1 | +- ipfixPhysicalEntity(3) = 6 | +- ipfixPhysicalEntityDirection(4) = 3 (both) | +- index(2) (ipfixObservationPointIndex) +- ipfixObservationPointGroupId(1) = 17 +- ipfixObservationPointIndex(2) = 2 +- ipfixPhysicalEntity(3) = 0 +- ipfixPhysicalEntityDirection(4) = 1 (ingress) Dietz, et al. draft-ietf-ipfix-mib-05.txt [Page 16] Internet-Draft IPFIX MIB November 2008 5.8. The Selector Table This table supports the usage of filtering and sampling functions as described in [I-D.ietf-ipfix-architecture]. The implementation and use of this table is optional. If implemented it contains lists of functions per Metering Process cache (ipfixMeteringProcessCacheId). The Selector Index indicates the order of the functions i.e, the order in that the functions are applied to the packets observed at the Observation Points associated with the Metering Process cache. The functions are referred by object identifiers pointing to the function with its parameters. If the table is implemented and no filtering or sampling is used for a Template then an entry for the Template should be created pointing to the Select All function (ipfixFuncSelectAll). 5.9. The Selector Functions The subtree ipfixSelectorFunctions is a placeholder where all standard filtering and sampling functions should be located (if any) and is mainly built for extensibility in future versions. It currently contains the Select All functions (ipfixFuncSelectAll). A future extension could produce e.g., the MIB tree shown in the following figure: ipfixSelectorFunctions | +- ipfixFuncSelectAll | | | +- ipfixFuncSelectAllAvail (is the function available?) | +- ipfixFuncF2 | | | +- ipfixFuncF2Avail (is the function F2 available) | | | +- ipfixFuncF2Parameters (a table with parameters) ... | +- ipfixFunFn... If a Selector Function takes parameters the MIB should contain a table with an entry for each set of parameters used at the Exporter. In this way a future extension could point to an entry in that table to indicate both the used Selector Function as well as the parameters used for that function. Dietz, et al. draft-ietf-ipfix-mib-05.txt [Page 17] Internet-Draft IPFIX MIB November 2008 5.10. The Transport Session Statistical Table The Transport Session Statistical Table (ipfixTransportSessionStatsTable) augments the ipfixTransportSessionTable with statistical values. It contains the rate (in bytes per second) with which it receives or sends out IPFIX Messages, the number of bytes, packets, messages, Records, Templates and Option Templates received or sent and the number of messages that were discarded. 5.11. The Template Statistical Table This table contains a statistical value for each Template. It augments the Template Table (ipfixTemplateTable) and specifies the number of Data Records exported or collected for the Template. 5.12. The Metering Process Statistical Table This table augments the Metering Process Table (ipfixMeteringProcessTable). It contains the statistical values for the IPFIX Messages and Data Records exported, the number of errors that occurred in the Metering Process and the number of active and inactive flows that are currently observed. 5.13. The Selector Statistical Table This table augments the Selector Table (ipfixSelectorTable) and introduces two generic statistical values, the number of packets observed and the number of packets dropped by the selector function. Dietz, et al. draft-ietf-ipfix-mib-05.txt [Page 18] Internet-Draft IPFIX MIB November 2008 6. Relationship to Other MIB Modules Besides the usual imports from the SNMP Standards [RFC2578], [RFC2579] and [RFC2580] the IPFIX MIB references the ENTITY MIB [RFC4133]. 6.1. Relationship to the ENTITY MIB The Observation Point table (ipfixObservationPointTable) contains a reference to the ENTITY MIB[RFC4133] (ipfixPhysicalEntity). If the implementors of the IPFIX MIB want to specify the physical entity where Flows are observed (if that is possible at all) then they should also implement the ENTITY MIB. The implementation of the ENTITY MIB is optional. If it is not implemented then all entries in the Observation Point table contain an ipfixPhysicalEntity of zero(0). 6.2. MIB modules required for IMPORTS The IPFIX MIB requires the modules SNMPv2-SMI[RFC2578], SNMPv2- TC[RFC2579] and SNMPv2-CONF[RFC2580]. Further on it imports the textual conventions InetAddressType and InetAddress from the INET ADDRESS MIB[RFC4001].

Security Considerations There are no management objects defined in this MIB module that have a MAX-ACCESS clause of read-write and/or read-create. So, if this MIB module is implemented correctly, then there is no risk that an intruder can alter or create any management objects of this MIB module via direct SNMP SET operations. Some of the readable objects in this MIB module (i.e., objects with a MAX-ACCESS other than not-accessible) may be considered sensitive or vulnerable in some network environments. It is thus important to control even GET and/or NOTIFY access to these objects and possibly to even encrypt the values of these objects when sending them over the network via SNMP. These are the tables and objects and their sensitivity/vulnerability: o ipfixTransportSessionTable - contains configuration data that might be sensitive o ipfixExportTable - contains configuration data that might be sensitive o ipfixMeteringProcessTable - contains configuration data that might be sensitive o ipfixObservationPointTable - contains configuration data that might be sensitive o ipfixSelectorFunctions - currently contains no sensitive data but might want to be secured anyway since it may contain sensitive data in a future version All other objects and tables contain no data that is considered sensitive. 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 Dietz, et al. draft-ietf-ipfix-mib-05.txt [Page 51] Internet-Draft IPFIX MIB November 2008 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.
