Last time it was working for chmod but this time when i am
trying to get log for open system call, i have made similar
changes in rules but did not get any log can you suggest
something. details are given below:
*rules*:
-a always,exit -F arch=b32 -S creat -S open -S openat -S
truncate -F exit=-EACCES -F auid!=4294967295 -k access
-a always,exit -F arch=b32 -S creat -S open -S openat -S
truncate -F exit=-EPERM -F auid!=4294967295 -k access
-a always,exit -F arch=b64 -S creat -S open -S openat -S
truncate -F exit=-EACCES -F auid!=4294967295 -k access
-a always,exit -F arch=b64 -S creat -S open -S openat -S
truncate -F exit=-EPERM -F auid!=4294967295 -k access
*strace output*: file have been attached named as "output for
open sytem call.txt"
strace -o /root/open_output open w
/root/test01
*
*
*auditctl -l output*: file have been attached named "auditctl
-l output.txt"

So that's the problem :)
root user id is 0 and your rule will only match user
id's >=
500 (which is usually used for regular users).
The auid field is the original user id. So if you were
logged
in as a regular user and tried to run chmod using sudo then
your rule would worked.
Try to remove the -F auid>=500.

The rule works for me.
# auditctl -a always,exit -F
arch=b64 -S
chmod -S
fchmod -S
fchmodat -F
'auid>=500' -F
auid!=4294967295 -k

I don't have any asterisk and I
have single
quote marks
since bash
will
interpret the > as a
redirection.
But then
doing a chmod
command,
it does pick
up the fchmodat() syscall.

When you use auditctl -l,
is the
rule just
like you
expected?
LIST_RULES: exit,always
arch=3221225534
(0xc000003e)
auid>=500
(0x1f4) auid!=-1
(0xffffffff) key=perm_mod
syscall=chmod,fchmod,fchmodat
It should just work unless
you are
on a
distribution
that
does not
really
support auditing.
