Abstract
This document defines a portion of the Management Information Base
(MIB) for use with network management protocols in TCP/IP-based
internets. In particular, it defines objects for monitoring firewall
devices.
Table of Contents
1. The Network Management Framework
The Internet-standard Network Management Framework consists of three
components. They are:
RFC 1902 [4] which defines the SMI, the mechanisms used for
describing and naming objects for the purpose of management.
Grall [Page 1]
Internet-Draft Firewall MIB 24 November 1997
STD 17, RFC 1213 [5] defines MIB-II, the core set of managed
objects for the Internet suite of protocols.
RFC 1157 [6] and RFC 1905 [7] which define two versions of the pro-
tocol used for network access to managed objects.
The Framework permits new objects to be defined for the purpose of
experimentation and evaluation.
Managed objects are accessed via a virtual information store, termed the
Management Information Base or MIB. Within a given MIB module, objects
are defined using RFC 1902's OBJECT-TYPE macro. At a minimum, each
object has a name, a syntax, an access-level, and an implementation-
status.
The name is an object identifier, an administratively assigned name,
which specifies an object type. The object type together with an object
instance serves to uniquely identify a specific instantiation of the
object. For human convenience, we often use a textual string, termed
the object descriptor, to also refer to the object type.
The syntax of an object type defines the abstract data structure
corresponding to that object type. The ASN.1[9] language is used for
this purpose. However, RFC 1155[3] purposely restricts the ASN.1 con-
structs which may be used. These restrictions are explicitly made for
simplicity.
2. Overview
This document specifies a working draft of a Management Information Base
(MIB) definition intended for use in monitoring firewall systems with
network management protocols in TCP/IP-based internets. All object
identifiers defined herein are under the private enterprises MIB tree.
This positioning would change if and when this MIB is adopted as stan-
dard.
This MIB is currently under review and revision by Internet security
management service providers. There will be at least two independent
reference implementations by the time this document reaches the Internet
Standard status. Furthermore, the immediate use of this MIB is focused
on the generation and interpretation of TRAP-signaled events and on
querying specific MIB objects.

Internet-Draft Firewall MIB 24 November 1997
2.1. Textual Conventions
Several new data types are introduced including Utf8String, EventTypeUn-
itTC, and ProtocolUnitTC.
2.1.1. Utf8String
The Utf8String textual convention is used for all string variables.
2.1.2. EventTypeUnitTC
This textual convention enumerates many kinds of common events that may
happen on a firewall. The list represents error conditions, unusual
events, and normal activities.
2.1.3. ProtocolUnitTC
This textual convention is an enumeration of the most common protocols
used with TCP/IP-based network firewalls.
2.2. Structure of MIB
The objects are arranged into the following groups:
- service identifiers (service)
- firewall event variables and logs (fwevent)
- firewall status and statistics data (fwquery)
- firewall traps (fwtrap)
These groups are the basic units of conformance. If a firewall imple-
ments a group, then it should implement all objects in that group. The
fwevent, fwquery and fwtrap groups are optional. If the fwtrap group is
implemented, the fwevent group must also be implemented. The services
group must be implemented if any of the other groups are implemented.
These groups are defined to provide a means of assigning object identif-
iers, and to provide a method for managed agents to know which objects
they must implement.
Grall [Page 3]
Internet-Draft Firewall MIB 24 November 1997
2.2.1. The Service Identifiers Group
The service group defines object identifiers (OIDs) for classes of ser-
vices and particular services handled by firewalls. These OIDs are used
as values in variables in other groups of the MIB to designate a ser-
vice.
2.2.2. The Firewall Event Variables and Logs Group
The fwevent group defines tables for logging events that take place on
the firewall. Management stations are notified of the events via traps
from the fwtrap group.
2.2.3. The Status and Statistics Group
The fwquery group contains status and statistic information. It
includes version information for the firewall and its modules, status
information for firewall services, and statistics measured by firewall
modules.
2.2.4. The Firewall Traps Group
The fwtrap group defines the traps that a firewall can send.
3. Monitoring of Firewall Devices
The scope of the MIB defined here is to provide information for the pur-
pose of monitoring firewall activity. The objects defined here provide
information about urgent events, security, health and status, and per-
formance of a firewall. This information is provided in two ways, via
traps and through objects that must be queried. The traps also have
associated information that can be queried.
It is worth noting areas this MIB is not meant to address. It is not
meant to replicate all firewall audit information or perform all of a
firewall's logging. The information provided by the MIB objects is not
necessarily all the information needed for a full audit capability. For
example, suspicious monitoring entities would probably require audit
information which should not be provided as part of this MIB. The MIB
is also not meant to be used for configuring a firewall. There are many
varieties of firewalls on the market and therefore many different ways
to configure them. This MIB does not have any variables related to con-
figuration items and currently does not have any variables with write
permission. So, SETs are not supported.
Grall [Page 4]
Internet-Draft Firewall MIB 24 November 1997
This section provides details on the expected use of the objects defined
in section "Definitions" below. It also presents some implementation
issues.
3.1. Events
Many of the objects in the MIB are related to events on the firewall.
An event as far as this MIB is concerned is what a trap is created for,
and what is stored in the event logs. An event can represent the
activity of a single user on the firewall, the status of a program on
the firewall, or a collection of firewall activities. It is up to the
firewall vendor to decide what activities on the firewall are
represented as events in the MIB.
In order to provide a common set of events for MIB users and management
status, the MIB includes an enumeration of event type, EventTypeUnitTC.
The list includes the most common events that happen on a firewall. The
comments included in the list describe the firewall activities each
entry is meant to represent. It is understood that the list will prob-
ably not represent all possible events any particular firewall may
report on and there are generic entries that can be used for these
cases.
While the MIB's main purpose is to report about "unusual" events on a
firewall, it was felt that the MIB should not disallow reporting related
to "normal" events. Items are included in EventTypeUnitTC to represent
"normal", "okay", "good", and "up" activities and conditions. A
firewall vender can then choose to report any kind of activity through
MIB events. For example, a firewall could equate a MIB event with an
audited event and report on all firewall activity with the MIB.
3.1.1. Event Logs and Traps
The fwevent group defines a set of log tables for storing information
about events. The fwtrap group defines a set of traps for reporting
about the events that have been recorded in the logs. These two groups
are meant to work together. Although it is possible to implement the
fwevent group without any trap support, this is not the purpose of the
logs in the fwevent group.
The event logs are represented by a set of tables. There is a basic
table that holds information common to every event, and there are other
tables that contain different sets of detailed information. Figure 1
provides a conceptual view of the tables. The basic table points to one
of the MIB detail tables by table OID and row index. The basic table
also (optionally) points to a firewall vendor defined details table.

Figure 1: Conceptual view of event log tables.
When an event (see section "Events") occurs on the firewall, the basic
table information is collected and, based on the event, a details table
is chosen and its information is collected as well. This information is
stored on the firewall and a trap from the fwtrap group is sent. The
trap contains the same information contained in the basic table. The
management station then has the option to query the firewall and ask for
the rows from the tables specified in the trap.
Which trap is sent depends on the details table chosen. For the
type1NetEventsLogTable, type2NetEventsLogTable, and
type3NetEventsLogTable details tables use the networkEventTrap trap.
For the healthEventsLogTable details table, use the healthEventTrap.
For the managementEventsLogTable details table use the managemen-
tEventTrap.
Since the trap contains the EventTypeUnitTC and EventDescription values
for the event, a user or management station can use these values to make
decisions on whether the event details are useful or not. The retrieval
of the details can be automated for many management stations. Appendix
A contains some configuration and script examples for some of the more
popular management tools.
Grall [Page 6]
Internet-Draft Firewall MIB 24 November 1997
3.1.2. Details Table Use
The MIB defines five log tables to record details about an event. Each
table includes a different set of information. Multiple tables were
defined rather than have one large table to lower the likelihood that
queries (and traps) would have many unneeded or undefined values.
The MIB does not dictate which details table must be used for recording
a particular event. In order to ease management station configuration
this section lists the preferred details table for each of the sets of
event in EventTypeUnitTC.
The following lists each of the sets from the EventTypeUnitTC and the
preferred details table used:

3.1.3. Trap Flooding
Under normal network conditions, one should not see many traps sent by a
firewall to a management station. There is a potential for a large
number of traps to be sent by a firewall implementing this MIB. This
depends on how the firewall maps activities to events and how many of a
particular event can occur in a short time. The MIB has no variables
related to controlling which traps are sent or to limit the number of
Grall [Page 7]
Internet-Draft Firewall MIB 24 November 1997
traps sent [@?@ if this turns out to be a widespread problem after ini-
tial reference implementation testing, it will be addressed in a later
draft of this MIB].
To provide firewall and SNMP management user some control it is sug-
gested that agent implementation provide some on/off configuration
options for the events a firewall will report about. Whether and how to
implement this and the granularity of the configuration control is
beyond the scope of this document.
3.1.4. Thresholds
It was stated earlier that a particular firewall vendor defines what a
MIB event is on their firewall. It is expected that some MIB events
will actually represent a set of activities on the firewall. For exam-
ple, EventTypeUnitTC has an event called login attempts. What is not
specified by the MIB is how many attempts happened before the event was
handled by the SNMP agent.
Individual thresholds for controlling which firewall activities are
represented as events in the MIB or for controlling which events should
generate traps are not specified in this MIB. Some activities are unin-
teresting when they occur occasionally, but more interesting when they
are more frequent. Firewall vendors decide which activities have thres-
holds and what kind of thresholds are available.
3.1.5. Log Tables
All of the log tables defined in the fwevent group are used and indexed
in the same way. This section addresses some implementation issues to
consider. The MIB does not dictate how the tables are implemented, just
how the values of the variables in a table row are used.
3.1.5.1. Table Size and Index Value
Table size is an implementation specific matter. Each table has an
index variable to uniquely identify a row in the table. The index is
assigned beginning with 1 when the table is created and increases by one
with each new log entry. Table creation will generally happen at
firewall system reboot, but may happen at any time (eg., when the
firewall's SNMP agent is restarted).
[@?@ comments received relate to preventing loss of the table informa-
tion between reboots, is this desired?]
Grall [Page 8]
Internet-Draft Firewall MIB 24 November 1997
The agent may choose to delete the rows of a table as needed. This may
be due to lack of space for the entries or due to other reasons (eg.,
the entries are too old). A query to the table cannot assume anything
about the table's size of whether a particular index value in the table
is valid or not.
Deletion of rows in the table may be based on age (ie., the smallest
valid index is deleted) or based on some other scheme (eg., the priority
of the event is lower than other events in the log). The MIB does not
place any requirements on which rows may or may not be deleted.
Each log table has a corresponding '...LogTableLastValidRow' object.
This variable can be used to obtain the index value of the last (or
newest) valid row in the table Since the index value starts at 1 and
monotonically increases with each new entry, one can see how many events
have been recorded since the creation of the table by obtaining this
variable.
3.1.5.2. Entry Order
The MIB places no requirements on the order of entries in the log
tables. The order of entries in a table will not necessarily be in the
same order as the traps that arrive at the management station. The
order of the entries in the basicEventsLogTable will not necessarily be
in order by the basicEventTime value.
3.1.5.3. MIB Walks
There is a concern that for implementations that choose to use a large
log table size (eg., 300 entries), that a MIB walk into the log table
will take a long time and will not necessarily be what the MIB walker
had in mind. For the log tables defined in the fwevent group (not the
tables in the fwquery group) the implementation may not return the first
valid row of the table, but instead may choose to return another row.
The row chosen may be, for instance, only 20 rows before the last valid
row. The default behavior will be to return the first valid row. In
particular, a GET NEXT on the '...LogTableLastValidRow' object will
return the '...EventLogIndex' variable. The value of the index will be
implementation defined. The value will be the index of a valid row in
the table, but whether that is the first valid row of the tenth from the
last is firewall specific.
[@?@ to walk through the whole table, should we provide a
'...LogTableFirstValidRow' object?]
Grall [Page 9]

4. Conventions
The following conventions are used throughout the Firewall MIB.
Good Packets
Good packets are error-free packets that have a valid frame length.
For example, on Ethernet, good packets are error-free packets that
are between 64 octets long and 1518 octets long. They follow the
form defined in IEEE 802.3 section 3.2.all.
Bad Packets
Bad packets are packets that have proper framing and are therefore
recognized as packets, but contain errors within the packet or have
an invalid length. For example, on Ethernet, bad packets have a
valid preamble and SFD, but have a bad CRC, or are either shorter
than 64 octets or longer than 1518 octets.
5. Definitions

Internet-Draft Firewall MIB 24 November 1997
-- This document specifies a working draft of a Management Information
-- Base (MIB) definition intended for use in managing firewall systems
-- with network management protocols in TCP/IP-based internets.
-- The object identifiers defined are used to identify
-- firewall entities such as the firewall services, packet filtering,
-- operating system services, etc.
-- In addition to traps, there are a number of variables which
-- could be queried by the management station in this MIB related to
-- the firewall resources, firewall statistics, etc.
-- Firewall Event Scheme
-- The event scheme used in the design of the trap messages is one based
-- on the idea of providing notification that an exceptional event occurred
-- and that the details can be queried from the firewall.
-- Event Examples
-- The following examples are included to illustrate the use of object
-- identifiers and additional trap variables in a TRAP to describe a
-- firewall event.
-- eg 1:
-- Event: a telnet proxy running on a firewall system 199.94.211.1, is
-- configured to deny access to users not connecting from a network, say
-- 199.94.200.0. When denying access to a user coming from 199.94.222.2,
-- the proxy service might generate the following trap.
-- The trap type is set to 6 (enterprise specific). A specific trap of
-- type 1 (networkEventTrap) is chosen to best describe this event. The
-- networkEventTrap includes variables to point to the basicEventsTable
-- and the type3NetLogEventDetailsTable.
--
-- For this specific event the details table describes the entity making
-- the connection attempt and why the attempt failed.

-- This fwmib is divided into four main groups. The first, spfw.service,

-- second, spfw.fwevent, Event variables and logs, is described briefly
-- above in the trap examples text. Third main group is spfw.fwquery,
-- the set of variables for queries. For a firewall this set is read only.
-- The fourth group, spfw.fwtrap, defines the traps for notification of
-- extraordinary events on the firewall.
--
-- There is also a group for specifying MIB conformance as described in
-- RFC1444, "Conformance Statements for version 2 of the Simple Network
-- Management Protocol (SNMPv2)".

--
-- service group
--
-- The service group defines OIDs that are used by other parts of the MIB.
-- The OIDs are used by traps to designate the generic service type
-- causing the trap. Expect this list to change occasionally as new service
-- types emerge in the network/firewall community. Once a service type
-- is in use by two or more firewall vendors it can be considered for
-- inclusion in the services group. This change is treated as any other
-- update to the MIB and will be included during a revision cycle.
-- This list does not differentiate between a local service (eg., local
-- login into the firewall via telnet) and a proxied service (eg., use of
-- a telnet application gateway). This information can be provided in a
-- string, since each use of these OIDs in a MIB variable (usually as
-- part of a table entry) has a corresponding description or information
-- variable.
-- Use of these OIDs in the MIB variables:
Grall [Page 21]
Internet-Draft Firewall MIB 24 November 1997
--
-- If a new service emerges that is not in the MIB yet, but that has been
-- assigned a port number or other identifying number, then it can be
-- represented by choosing the appropriate service category and using the
-- assigned number. For example, a new service called Foo Protocol (fp)
-- is the latest rage on the Internet. It is a multi-media protocol and
-- has been assigned port number XXX. The OID used to represent the
-- service would be spfw.service.svcMultimedia.XXX. The corresponding
-- information variable can provide the protocol name.
--
-- If the firewall supports a service or protocol that is very unique or
-- specific to that firewall, then the OID used to represent the service
-- will include that vendor's enterprise number. For example, the Foo
-- firewall has a Bar service. The firewall company's enterprise number
-- is ZZZ and they have chosen W to represent the Bar service. The
-- OID used would be spfw.service.svcOther.ZZZ.W It is the vendor's
-- responsibility to publish definitions of the numbers used.
--
-- In any of the cases above where a service listed below cannot be used,
-- the service can be further described with the serviceInformation object.
--
-- The numbers assigned in the list correspond, when possible, to the
-- assigned port number for a protocol or other assigned number as
-- appropriate (eg., the protocol number for IP protocols).
--
-- Alternatively a vendor can define an OID in their enterprise tree and
-- use that value for genericService. It is the vendor's responsibility
-- to publish these OIDs.

-- The firewall event group
--
-- The firewall event group defines a set of variables and tables used to
-- log and track extraordinary firewall events. The tables are filled in
-- when an event occurs and then trap is sent referencing the filled in
-- row.
-- For any particular event up to three tables will be referenced. The
-- general event information will go into one table and the details are
-- placed in another. A third vendor defined table can also be used.
-- There is only one table defined for general information.
-- The table chosen for event details depends on the event type and the
-- set of detailed information available at the time the event took place.
-- The general table has a value to point to the table and row containing
-- the event's details. A trap is sent once the relevant tables are
-- filled in. The trap contains pointers to the tables used.
-- A management station can wait for a trap to get details on an event.
-- Alternatively the management station can query the objects in this
-- group at any time to retrieve event information.

-- Traps are defined using the conventions in SNMPv2-SMI
--
-- The networkEventTrap is used for events related to the network
-- operation in the firewall. This includes packet screening events and
-- serviceevents. Thetrap contains OID and row indexes of both the
-- details table and the vendor private table. Then the management
-- station can choose to access the event details without having to query
-- the base table.
