AUDITCONFIG(1M) Maintenance Commands AUDITCONFIG(1M)

auditconfig - configure auditing

auditconfig option...

auditconfig provides a command line interface to get and set kernel audit parameters.

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; setting these policies requires the privileges of a global zone administrator. perzone and ahlt are described under the -setpolicy option, below.

-aconf

Set the non-attributable audit mask to the value set using the -setnaflags option. For example:


# auditconfig -aconf
Configured non-attributable event mask.

-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 that the current non-attributable event flags set in the kernel matches the configuration. 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 mappings are changed to match those in the audit event to class database 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); or nospace, meaning there is no space for saving audit records. See auditon(2) and auditd(1M) for further information.

-getcwd

Prints current working directory (anchored from zone root at system boot). For example:


# cd /usr/tmp
# auditconfig -getcwd
current working directory = /var/tmp

-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

-getflags

Display the current active and configured user default audit flags. For example:


# auditconfig -getflags
active user default audit flags = no(0x0,0x0)
configured user default audit flags = ex,lo(0x40001000,0x40001000)

-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.

-getnaflags

Display the current active and configured non-attributable audit flags. For example:


# auditconfig -getnaflags
active non-attributable audit flags = no(0x0,0x0)
configured non-attributable audit flags = lo(0x1000,0x1000)

-getpinfo pid

Display the audit ID, preselection mask, terminal ID, and audit session ID for the specified process.

-getplugin [plugin]

Display the currently installed plugins and their attributes. If plugin is specified, -getplugin only shows information for that plugin. For example:


# auditconfig -getplugin
Plugin: audit_binfile (active)
        Attributes: p_dir=/var/audit;p_fsize=0;p_minfree=0;
Plugin: audit_syslog (inactive)
        Attributes: p_flags=;
Plugin: audit_remote (inactive)
        Attributes: p_hosts=;p_retries=3;p_timeout=5;

-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.

-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

# auditconfig -getqhiwater
audit queue hiwater mark (records) = 100

-getqlowater

Get low water point in undelivered audit records where blocked processes will resume. For example:


# auditconfig -getqlowater
audit queue lowater mark (records) = 10

-getstat

# 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.

-setflags audit_flags

Sets the user default audit flags. For example, to set execute and login auditing for all users:


# auditconfig -setflags ex,lo
user default audit flags = ex,lo(0x40001000,0x40001000)

-setkaudit IP-address_type IP_address

Set the preselection mask of the specified process.

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 policies 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 arguments to the audit record. This information is not included by default.

argv

Include the execv(2) system call parameter arguments 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 operations 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 perzone 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.

Example 1 Using auditconfig

The following is an example of an auditconfig program:


#
# map kernel audit event number 10 to the "fr" audit class
#
% auditconfig -setclass 10 fr
#
# turn on inclusion of exec arguments in exec audit records
#
% auditconfig -setpolicy +argv

0
Successful completion.

1

An error occurred.

/etc/security/audit_event
Stores event definitions used in the audit system.

/etc/security/audit_class

Stores class definitions used in the audit system.

See attributes(5) for descriptions of the following attributes:

ATTRIBUTE TYPE ATTRIBUTE VALUE
Interface Stability Committed

audit(1M), auditd(1M), auditstat(1M), praudit(1M), auditon(2), execv(2), audit_class(4), audit_event(4), attributes(5), audit_binfile(5), audit_remote(5), audit_syslog(5)

If the audit_remote or audit_syslog plugins are active, 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 continue 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 overridden by means of the qsize attribute.

The auditconfig options that modify or display process-based information 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 disable auditing.

The -getfsize and -setfsize options have been removed. Use audit_binfile(5) p_fsize to set the audit file size.
