AUDITCONFIG(1M)AUDITCONFIG(1M)NAMEauditconfig - configure auditing
SYNOPSISauditconfig option...
DESCRIPTIONauditconfig provides a command line interface to get and set kernel
audit parameters.
This functionality is available only if the Solaris Auditing feature
has been enabled. See bsmconv(1M) for more information.
The setting of the perzone policy determines the scope of the audit
setting controlled by auditconfig. If perzone is set, then the values
reflect the local zone except as noted. Otherwise, the settings are for
the entire system. Any restriction based on the perzone setting is
noted for each option to which it applies.
A non-global zone administrator can set all audit policy options except
perzone and ahlt. perzone and ahlt apply only to the global zone; set‐
ting these policies requires the privileges of a global zone adminis‐
trator. perzone and ahlt are described under the -setpolicy option,
below.
OPTIONS-aconf
Set the non-attributable audit mask from the audit_control(4) file.
For example:
# auditconfig-aconf
Configured non-attributable events.
-audit event sorf retval string
This command constructs an audit record for audit event event using
the process's audit characteristics containing a text token string.
The return token is constructed from the sorf (success/failure
flag) and the retval (return value). The event is type char*, the
sorf is 0/1 for success/failure, retval is an errno value, string
is type *char. This command is useful for constructing an audit
record with a shell script. An example of this option:
# auditconfig-audit AUE_ftpd 0 0 "test string"
#
audit record from audit trail:
header,76,2,ftp access,,Fri Dec 08 08:44:02 2000, + 669 msec
subject,abc,root,other,root,other,104449,102336,235 197121 elbow
text,test string
return,success,0
-chkaconf
Checks the configuration of the non-attributable events set in the
kernel against the entries in audit_control(4). If the runtime
class mask of a kernel audit event does not match the configured
class mask, a mismatch is reported.
-chkconf
Check the configuration of kernel audit event to class mappings. If
the runtime class mask of a kernel audit event does not match the
configured class mask, a mismatch is reported.
-conf
Configure kernel audit event to class mappings. Runtime class map‐
pings are changed to match those in the audit event to class data‐
base file.
-getasid
Prints the audit session ID of the current process. For example:
# auditconfig-getasid
audit session id = 102336
-getaudit
Returns the audit characteristics of the current process.
# auditconfig-getaudit
audit id = abc(666)
process preselection mask = lo(0x1000,0x1000)
terminal id (maj,min,host) = 235,197121,elbow(172.146.89.77)
audit session id = 102336
-getauid
Prints the audit ID of the current process. For example:
# auditconfig-getauid
audit id = abc(666)-getcar
Prints current active root location (anchored from root [or local
zone root] at system boot). For example:
# auditconfig-getcar
current active root = /
-getclass event
Display the preselection mask associated with the specified kernel
audit event. event is the kernel event number or event name.
-getcond
Display the kernel audit condition. The condition displayed is the
literal string auditing meaning auditing is enabled and turned on
(the kernel audit module is constructing and queuing audit
records); noaudit, meaning auditing is enabled but turned off (the
kernel audit module is not constructing and queuing audit records);
disabled, meaning that the audit module has not been enabled; or
nospace, meaning there is no space for saving audit records. See
auditon(2) and auditd(1M) for further information.
-getestate event
For the specified event (string or event number), print out classes
event has been assigned. For example:
# auditconfig-getestate 20
audit class mask for event AUE_REBOOT(20) = 0x800
# auditconfig-getestate AUE_RENAME
audit class mask for event AUE_RENAME(42) = 0x30
-getkaudit
Get audit characteristics of the current zone. For example:
# auditconfig-getkaudit
audit id = unknown(-2)
process preselection mask = lo,na(0x1400,0x1400)
terminal id (maj,min,host) = 0,0,(0.0.0.0)
audit session id = 0
If the audit policy perzone is not set, the terminal id is that of
the global zone. Otherwise, it is the terminal id of the local
zone.
-getkmask
Get non-attributable pre-selection mask for the current zone. For
example:
# auditconfig-getkmask
audit flags for non-attributable events = lo,na(0x1400,0x1400)
If the audit policy perzone is not set, the kernel mask is that of
the global zone. Otherwise, it is that of the local zone.
-getpinfo pid
Display the audit ID, preselection mask, terminal ID, and audit
session ID for the specified process.
-getpolicy
Display the kernel audit policy. The ahlt and perzone policies
reflect the settings from the global zone. If perzone is set, all
other policies reflect the local zone's settings. If perzone is not
set, the policies are machine-wide.
-getcwd
Prints current working directory (anchored from zone root at system
boot). For example:
# cd /usr/tmp
# auditconfig-getcwd
current working directory = /var/tmp
-getqbufsz
Get audit queue write buffer size. For example:
# auditconfig-getqbufsz
audit queue buffer size (bytes) = 1024
-getqctrl
Get audit queue write buffer size, audit queue hiwater mark, audit
queue lowater mark, audit queue prod interval (ticks).
# auditconfig-getqctrl
audit queue hiwater mark (records) = 100
audit queue lowater mark (records) = 10
audit queue buffer size (bytes) = 1024
audit queue delay (ticks) = 20
-getqdelay
Get interval at which audit queue is prodded to start output. For
example:
# auditconfig-getqdelay
audit queue delay (ticks) = 20
-getqhiwater
Get high water point in undelivered audit records when audit gener‐
ation will block. For example:
# ./auditconfig -getqhiwater
audit queue hiwater mark (records) = 100
-getqlowater
Get low water point in undelivered audit records where blocked pro‐
cesses will resume. For example:
# auditconfig-getqlowater
audit queue lowater mark (records) = 10
-getstat
Print current audit statistics information. For example:
# auditconfig-getstat
gen nona kern aud ctl enq wrtn wblk rblk drop tot mem
910 1 725 184 0 910 910 0 231 0 88 48
See auditstat(1M) for a description of the headings in -getstat
output.
-gettid
Print audit terminal ID for current process. For example:
# auditconfig-gettid
terminal id (maj,min,host) = 235,197121,elbow(172.146.89.77)
-lsevent
Display the currently configured (runtime) kernel and user level
audit event information.
-lspolicy
Display the kernel audit policies with a description of each pol‐
icy.
-setasid session-ID [cmd]
Execute shell or cmd with specified session-ID. For example:
# ./auditconfig -setasid 2000 /bin/ksh
#
# ./auditconfig -getpinfo 104485
audit id = abc(666)
process preselection mask = lo(0x1000,0x1000)
terminal id (maj,min,host) = 235,197121,elbow(172.146.89.77)
audit session id = 2000
-setaudit audit-ID preselect_flags term-ID session-ID [cmd]
Execute shell or cmd with the specified audit characteristics.
-setauid audit-ID [cmd]
Execute shell or cmd with the specified audit-ID.
-setclass event audit_flag[,audit_flag ...]
Map the kernel event event to the classes specified by audit_flags.
event is an event number or name. An audit_flag is a two character
string representing an audit class. See audit_control(4) for fur‐
ther information. If perzone is not set, this option is valid only
in the global zone.
-setkaudit IP-address_type IP_address
Set IP address of machine to specified values. IP-address_type is
ipv6 or ipv4.
If perzone is not set, this option is valid only in the global
zone.
-setkmask audit_flags
Set non-attributes selection flags of machine.
If perzone is not set, this option is valid only in the global
zone.
-setpmask pid flags
Set the preselection mask of the specified process. flags is the
ASCII representation of the flags similar to that in audit_con‐
trol(4).
If perzone is not set, this option is valid only in the global
zone.
-setpolicy [+|-]policy_flag[,policy_flag ...]
Set the kernel audit policy. A policy policy_flag is literal
strings that denotes an audit policy. A prefix of + adds the poli‐
cies specified to the current audit policies. A prefix of - removes
the policies specified from the current audit policies. No policies
can be set from a local zone unless the perzone policy is first set
from the global zone. The following are the valid policy flag
strings (auditconfig -lspolicy also lists the current valid audit
policy flag strings):
all
Include all policies that apply to the current
zone.
ahlt
Panic is called and the system dumps core if an
asynchronous audit event occurs that cannot be
delivered because the audit queue has reached the
high-water mark or because there are insufficient
resources to construct an audit record. By
default, records are dropped and a count is kept of
the number of dropped records.
arge
Include the execv(2) system call environment argu‐
ments to the audit record. This information is not
included by default.
argv
Include the execv(2) system call parameter argu‐
ments to the audit record. This information is not
included by default.
cnt
Do not suspend processes when audit resources are
exhausted. Instead, drop audit records and keep a
count of the number of records dropped. By default,
process are suspended until audit resources become
available.
group
Include the supplementary group token in audit
records. By default, the group token is not
included.
none
Include no policies. If used in other than the
global zone, the ahlt and perzone policies are not
changed.
path
Add secondary path tokens to audit record. These
are typically the pathnames of dynamically linked
shared libraries or command interpreters for shell
scripts. By default, they are not included.
perzone
Maintain separate configuration, queues, and logs
for each zone and execute a separate version of
auditd(1M) for each zone.
public
Audit public files. By default, read-type opera‐
tions are not audited for certain files which meet
public characteristics: owned by root, readable by
all, and not writable by all.
trail
Include the trailer token in every audit record. By
default, the trailer token is not included.
seq
Include the sequence token as part of every audit
record. By default, the sequence token is not
included. The sequence token attaches a sequence
number to every audit record.
windata_down
Include in an audit record any downgraded data
moved between windows. This policy is available
only if the system is configured with Trusted
Extensions. By default, this information is not
included.
windata_up
Include in an audit record any upgraded data moved
between windows. This policy is available only if
the system is configured with Trusted Extensions.
By default, this information is not included.
zonename
Include the zonename token as part of every audit
record. By default, the zonename token is not
included. The zonename token gives the name of the
zone from which the audit record was generated.
-setqbufsz buffer_size
Set the audit queue write buffer size (bytes).
-setqctrl hiwater lowater bufsz interval
Set the audit queue write buffer size (bytes), hiwater audit record
count, lowater audit record count, and wakeup interval (ticks).
Valid within a local zone only if perzone is set.
-setqdelay interval
Set the audit queue wakeup interval (ticks). This determines the
interval at which the kernel pokes the audit queue, to write audit
records to the audit trail. Valid within a local zone only if per‐
zone is set.
-setqhiwater hiwater
Set the number of undelivered audit records in the audit queue at
which audit record generation blocks. Valid within a local zone
only if perzone is set.
-setqlowater lowater
Set the number of undelivered audit records in the audit queue at
which blocked auditing processes unblock. Valid within a local zone
only if perzone is set.
-setsmask asid flags
Set the preselection mask of all processes with the specified audit
session ID. Valid within a local zone only if perzone is set.
-setstat
Reset audit statistics counters. Valid within a local zone only if
perzone is set.
-setumask auid flags
Set the preselection mask of all processes with the specified audit
ID. Valid within a local zone only if perzone is set.

NOTES
If plugin output is selected using audit_control(4), the behavior of
the system with respect to the -setpolicy +cnt and the -setqhiwater
options is modified slightly. If -setpolicy +cnt is set, data will con‐
tinue to be sent to the selected plugin, even though output to the
binary audit log is stopped, pending the freeing of disk space. If
-setpolicy-cnt is used, the blocking behavior is as described under
OPTIONS, above. The value set for the queue high water mark is used
within auditd as the default value for its queue limits unless overrid‐
den by means of the qsize attribute as described in audit_control(4).
The auditconfig options that modify or display process-based informa‐
tion are not affected by the perzone policy. Those that modify system
audit data such as the terminal id and audit queue parameters are valid
only in the global zone, unless the perzone policy is set. The display
of a system audit reflects the local zone if perzone is set. Otherwise,
it reflects the settings of the global zone.
The -setcond option has been removed. Use audit(1M) to enable or dis‐
able auditing.
The -getfsize and -setfsize options have been removed. Use audit_bin‐
file(5) p_fsize to set the audit file size.
