UNIX for Dummies Questions & Answers

you auditd config should like the following:


run

/etc/security/bsmconv

make sure the /etc/system has been update
(set c2audit:audit_load = 1)

reboot


vi audit_startup

/usr/bin/echo "Starting BSM services."
/usr/sbin/auditconfig -conf
/usr/sbin/auditconfig -aconf
/usr/sbin/auditconfig -setpolicy +argv

Add the following class to you /etc/security/audit_class

0x08000000:cc:CIS custom class

vi the audit_event

find entry 23 and add cc, just like the following entry:

23:AUE_EXECVE:execve(2)s,ex,cc

vi audit_control

make sure that you have the following lines:

dir:/var/audit
flags:lo,ad,cc
minfree:20
naflags:lo

vi audit_user

where userX is the name of the user you want to audit.

userX:lo:no
userX:lo,ad,cc,exec,all
userX:lo,ad,cc,exec,al


to get any reading from your logs use the below command:

auditreduce -c lo /var/audit/20070329110000.not_terminated.*servername* |praudit

and that will give you what you want !!
good luck.

hi auditd. Its ok now
Thanks for yor help.

Hello all,

I am working with a solaris 10 system that has minimum 250 users on it during any business day. I need to track all +ex where the effective uid is root and nothing more. BSM seems like the best tool for this because of how well it tracks each user with it's audit-id.

I have root:+ex in my audit_user file, however this setting applies only for console logins of root because we do not allow remote. I have flags: +ex in my audit_control file, however this setting with the number of users I have will generate an audit trail which is too large for my file system with a ton of unnecessary data. Does anyone know how I could setup BSM to audit only the effective UID of root?

I need to find some answers for this, according to the manuals this BSM auditing when turned on uses up a lot of disk space, my question is how much disk will the logs use up every month?

Also does anybody also know what is the equivalent of solaris BSM on hpux, does HPUX have any built in auditing capabilities similiar to solaris?

How long is a piece of string?

The problem is that it depends on a lot of things, like:
The best way is to start auditing using the settings you want and closely monitor the audit trail, and then tune the settings if they grow too large.

I have system which generates over 100 MB/day and I have others which generates less than 1 MB/day - using the same audit settings.
