       audispd-zos-remote - z/OS Remote-services Audit dispatcher plugin

SYNOPSIS         top

       audispd-zos-remote [ config-file ]

DESCRIPTION         top

       audispd-zos-remote is a remote-auditing plugin for the Audit
       subsystem. It should be started by the audispd(8) daemon and will
       forward all incoming audit events, as they happen, to a configured
       z/OS SMF (Service Management Facility) database, through an IBM
       Tivoli Directory Server (ITDS) set for Remote Audit service.  See SMF
       MAPPING section below for more information about the resulting SMF
       record format.

       audispd(8) must be configured to start the plugin. This is done by a
       configuration file usually located at
       /etc/audisp/plugins.d/audispd-zos-remote.conf, but multiple instances
       can be spawned by having multiple configuration files in
       /etc/audisp/plugins.d for the same plugin executable (see

       Each instance needs a configuration file, located by default at
       /etc/audisp/zos-remote.conf.  Check zos-remote.conf(5) for details
       about the plugin configuration.

SIGNALS         top

       audispd-zos-remote reacts to SIGTERM and SIGHUP signals (according to
       the audispd(8) specification):

       SIGHUP Instructs the audispd-zos-remote plugin to re-read it's
              configuration and flush existing network connections.

              Performs a clean exit.  audispd-zos-remote will wait up to 10
              seconds if there are queued events to be delivered, dropping
              any remaining queued events after that time.

IBM z/OS ITDS Server and RACF configuration         top

       In order to use this plugin, you must have an IBM z/OS v1R8 (or
       higher) server with IBM Tivoli Directory Server (ITDS) configured for
       Remote Audit service. For more detailed information about how to
       configure the z/OS server for Remote Auditing, refer to z/OS
       V1R8.0-9.0 Intergrated Security Services Enterprise Identity Mapping
       (EIM) Guide and Reference
       ( ),
       chapter "2.0 - Working with remote services".

   Enable ITDS to process Remote Audit requests
       To enable ITSD to process Remote Audit requests, the user ID
       associated with ITDS must be granted READ access to the IRR.AUDITX
       FACILITY Class profile (the profile used to protect the R_Auditx
       service). This user ID can usually be found in the STARTED Class
       profile for the ITDS started procedure. If the identity associated
       with ITDS is ITDSUSER, the administrator can configure RACF to grant
       Remote Auditing processing to ITDS with the following TSO commands:

       TSO Commands: Grant ITDSUSER READ access to IRR.AUDITX FACILITY Class
              rdefine FACILITY IRR.RAUDITX uacc(none)
              permit IRR.RAUDITX class(FACILITY) id(ITDSUSER) access(READ)

   Create/enable RACF user ID to perform Remote Audit requests
       A z/OS RACF user ID is needed by the plugin - Every Audit request
       performed by the plugin will use a RACF user ID, as configured in the
       plugin configuration zos-remote.conf(5).  This user ID needs READ
       access to FACILITY Class resource IRR.LDAP.REMOTE.AUDIT. If the user
       ID is BINDUSER, the administrator can configure RACF to enable this
       user to perform Remote Auditing requests with the following TSO

       TSO Commands: Enable BINDUSER to perform Remote Audit requests
              rdefine FACILITY IRR.LDAP.REMOTE.AUDIT uacc(none)
              permit IRR.LDAP.REMOTE.AUDIT class(FACILITY) id(BINDUSER) access(READ)

   Add @LINUX Class to RACF
       When performing remote auditing requests, the audispd-zos-remote
       plugin will use the special @LINUX CDT Class and the audit record
       type (eg.: SYSCALL, AVC, PATH...)  as the CDT Resource Class for all
       events processed.  To make sure events are logged, the RACF server
       must be configured with a Dynamic CDT Class named @LINUX with correct
       sizes and attributes. The following TSO commands can be used to add
       this class:

       TSO Commands: Add @LINUX CDT Class
              rdefine cdt @LINUX cdtinfo(posit(493) FIRST(alpha,national,numeric,special) OTHER(alpha,national,numeric,special) RACLIST(REQUIRED) case(asis) generic(allowed) defaultuacc(none) maxlength(246))
              setr classact(cdt)
              setr raclist(cdt)
              setr raclist(cdt) refresh
              setr classact(@LINUX)
              setr raclist(@LINUX)
              setr generic(@LINUX)

   Add profiles to the @LINUX Class
       Once the CDT Class has been defined, you can add profiles to it,
       specifying resources (wildcards allowed) to log or ignore. The
       following are examples:

       TSO Commands: Log only AVC records (One generic and one discrete
              rdefine @LINUX * uacc(none) audit(none(read))
              rdefine @LINUX AVC uacc(none) audit(all(read))
              setr raclist(@LINUX) refresh

       TSO Commands: Log everything (One generic profile):
              rdefine @LINUX * uacc(none) audit(all(read))
              setr raclist(@LINUX) refresh

       Resources always match the single profile with the best match.

       There are many other ways to define logging in RACF. Please refer to
       the server documentation for more details.

SMF Mapping         top

       The ITDS Remote Audit service will cut SMF records of type 83 subtype
       4 everytime it processes a request. This plugin will issue a remote
       audit request for every incoming Linux Audit record (meaning that one
       Linux record will map to one SMF record), and fill this type's
       records with the following:

   Link Value
       The Linux event serial number, encoded in network-byte order
       hexadecimal representation. Records within the same Event share the
       same Link Value.

       Always zero (0) - False

   Event Code
       Always two (2) - Authorization event

   Event Qualifier
       Zero (0) - Success, if the event reported success=yes or res=success,
       Three (3) - Fail, if the event reported success=no or res=failed, or
       One (1) - Info otherwise.

       Always @LINUX

       The Linux record type for the processed record. e.g.:

   Log String
       Textual message bringing the RACF user ID used to perform the
       request, plus the Linux hostname and the record type for the first
       record in the processed event. e.g.: Remote audit request from
       RACFUSER. Linux (hostname.localdomain):USER_AUTH

   Data Field List
       Also known as relocates, this list will bring all the field names and
       values in a fieldname=value format, as a type 114 (Appication
       specific Data) relocate. The plug-in will try to interpret those
       fields (i.e.: use human-readable username root instead of numeric
       userid 0) whenever possible. Currently, this plugin will also add a
       relocate type 113 (Date And Time Security Event Occurred) with the
       Event Timestamp in the format as returned by ctime(3).

ERRORS         top

       Errors and warnings are reported to syslog (under DAEMON facility).
       In situations where the event was submitted but the z/OS server
       returned an error condition, the logged message brings a name
       followed by a human-readable description. Below are some common
       errors conditions:

       NOTREQ - No logging required
              Resource (audit record type) is not set to be logged in the
              RACF server - The @LINUX Class profile governing this audit
              record type is set to ignore. See IBM z/OS RACF Server

       UNDETERMINED - Undetermined result
              No profile found for specified resource. There is no @LINUX
              Class configured or no @LINUX Class profile associated with
              this audit record type. See IBM z/OS RACF Server configuration

       UNAUTHORIZED - The user does not have authority the R_auditx service
              The user ID associated with the ITDS doesn't have READ access
              to the IRR.AUDITX FACILITY Class profile. See IBM z/OS RACF
              Server configuration

       UNSUF_AUTH - The user has unsuficient authority for the requested
              The RACF user ID used to perform Remote Audit requests (as
              configured in zos-remote.conf(5)) don't have access to the
              IRR.LDAP.REMOTE.AUDIT FACILITY Class profile. See IBM z/OS
              RACF Server configuration

BUGS         top

       The plugin currently does remote auditing in a best-effort basis, and
       will dischard events in case the z/OS server cannot be contacted
       (network failures) or in any other case that event submission fails.
