There are LOTS of the following:

There are also some like this, but syscall=open instead.
During this time, I am logged in to a GUI, but the screensaver has
activated, and I am doing nothing. No one else has an account.
Well, herein lies the rub...the audit rules you have in place are doing
their job.
:)
The escd is creating device files as it does its thing...do you trust
it? Assuming so, maybe there is a way to filter those out.
Can you send a couple of the results of this command? This will tell you
the top (recent) auditing processes:
% sudo aureport -ts recent -i -x --summary
Also a couple of of these results (since you said there were a lot of
escd process events). Change "recent" to "today" or a specific start
time (see ausearch man page):
% sudo ausearch -ts recent -i -c escd
^^^^^^^^^^^^^^^^
These are the top results for the ausearch command given above:
930 /usr/lib64/esc-1.1.0/escd
82 /usr/libexec/abrt-hook-ccpp
44 /usr/sbin/sshd
43 /usr/sbin/crond
41 /usr/sbin/usermod
34 /sbin/unix_chkpwd
31 /usr/bin/sudo
24 /bin/ls
22 /usr/sbin/abrtd (deleted)
21 /usr/sbin/httpd
17 /usr/libexec/openssh/sftp-server
15 /bin/su
14 /usr/libexec/gnome-screensaver-dialog
14 /usr/sbin/cupsd
OK. It appears that the RH smart card reader software is doing this, which is odd,
considering I'm not using a smart card right now. I'll disable it (for now) and
see what happens. But I'm going to want it working eventually.
