There are only 10 - 15 apps that are "trusted apps". They are logging events 
that are required by various security standards such as common criteria, DISA 
STIG, PCI DSS, etc.

While that may be true, it is generally not the case that they do in fact 
log.

If you must, sure. Trusted app events are in the 1100-1199 range. But which 
app is causing the problems that you see? In the past, we had to silence 
crond because it was noisy.

The rules in that dir are insufficient to fulfill regulatory requirements. If 
you are doing some kind of syscall experiment, then I can see that you might 
want to turn them off. But if your aim is meeting some kind of standard, then 
other events are required.
