The open syscall can be used to create new files
when O_CREAT flag is specified.
The following audit rules will assure that successful attempts to create a
file via open syscall are collected.
If the auditd daemon is configured to use the augenrules
program to read audit rules during daemon startup (the default), add the
rules below to a file with suffix .rules in the directory
/etc/audit/rules.d.
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the rules below to
/etc/audit/audit.rules file.
-a always,exit -F arch=b32 -S open -F a2&0100 -F success=1 -F auid>=1000 -F auid!=unset -F key=successful-create
If the system is 64 bit then also add the following lines:
-a always,exit -F arch=b64 -S open -F a2&0100 -F success=1 -F auid>=1000 -F auid!=unset -F key=successful-create
