How to enable Audit log for specific users and events in HP-UX 11.31 ?


How to enable Audit log for specific users and events in HP-UX 11.31 ?

Hi All,

As per management decission, I need to enable audit trail in HP-UX .  So I have enable audit by command 

audsys -n . So now how to configure it only for users?


Please need assist  for this issue from expert end.


Re: How to enable Audit log for specific users and events in HP-UX 11.31 ?

Take a look at this technical paper on the subject:

p15 onwards starts to describe how to configure auditing for specific users and events, but I would read the whole thing to get a better understanding of what's really going on.

Enabling auditing on HP-UX requires fair knowlegde on how it works. Since it deals with Security, you must take time to read through the documentation.

One more important aspect is managing the auditing logs. For example, unless you plan properly you run the risk of exhausting file system space. And there is a need to archive them on a regualr basis for record-keeping etc. 

I suggest that you go through the documentations for auditing thouroughly before embarking on this journey. You will find all documents at this location -

Some of the documents I usually refer are:

HP-UX 11iv2 and 11iv3 Security Configuring and Managing the Auditing System

HP-UX System Administrators Guide Security Management HP-UX 11i Version 3

Hope it helps. All the best.

Hello again,

The events, users, calls etc that can be configured are documented in /etc/audit/audit.conf. Site-specific config files will have to be included in another file /etc/audit/audit_site.conf.

The events can also be passed againts AUDEVENT_ARGS in /etc/rc.config.d/auditing

As I mentioned in my earlier post, it is important that you read through the documentation to understand how the auditing on HP-UX works.

As  you can see from the depth of the auditing system, there can be an immense effort to setup and maintain the records. Then there is the question on how to immediately notify sysadmins of a potential problem.

You may find that simply keeping the login shell history would satisfy your management's request. Note that this would cover simple commands and possible mistakes, but would not be adequate for knowledgeable users trying to hide their activities.

Hi All,

I have studied all document as per my strenth.

I have run all command in my test system. Here OS version is HP-UX 11.31   . After success, then we will run on live system

I have set to audit for user root and oracle only. Please check the command output as bellow .(#userdbget -a | grep AUDIT_FLAG=1)
I set only the events associated with the basic profile for auditing, use the following   command:
# audevent -P -F -r basic , please check the config log as bellow  by # cat /etc/audit/audit.conf

Also check the output by # cat /etc/rc.config.d/auditing

From /var/.audit location, I see the bellow file size

bash-4.3# du -sk audfile2.20200211_1235
12312 audfile2.20200211_1235
bash-4.3# du -sk audfile2.20200211_1241
1776 audfile2.20200211_1241

Command output:

bash-4.3# userdbget -a | grep AUDIT_FLAG=1
oracle AUDIT_FLAG=1

bash-4.3# cat /etc/rc.config.d/auditing
