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


       audispd-zos-remote [ config-file ]


       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 audispd(8)).

       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.


              Use    an    alternate    configuration    file    instead    of


       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

       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 commands:

       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

       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

   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 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 configuration

       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

       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


       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.
