Hi,
I have done some analysis and digging into how both the watch rules and
syscall rules are translated.
From my understanding, in terms of logging, both the below rules are
similar. There is no difference in either of the rules.
1. -w /etc -p wa -k ETC_WATCH
They are similar in this case.
-w behaves differently depending on the existance of the watched entity
and the presence of a trailing "/". This is why the form above is
deprecated.
2. -a always,exit -F arch=b64 -S <all syscalls part of the write
and attr
classes> -F dir=/etc -F perm=wa -k ETC_WATCH
The write and attr classes consist of syscalls in
“include/asm-generic/audit_*.h“.
The perm flag is needed in the second case for including open/openat
syscalls which are not a part of the write and attr syscall list.
I'd like to verify if what I mentioned earlier is accurate, and I have an
additional point but depends on whether this is accurate.
