This ^^^ is wrong. For example, it does not limit the syscall by the arch. So what this means is that it will look up the open syscall for the arch that auditctl is. So, lets see what that does: # ausyscall open open 2 OK, now what does the 32 bit API think of it? # ausyscall 2 i386 fork So, that rule will watch for all 32 bit forks and 64 bit opens. Is that what your security folks want? Additionally, the intent of the STIG is to catch failed opens due to permission problems. You are going to trap normal system activity when glibc goes looking around for library resolution information. This will waste space in your logs and make it hard to find actual problems. > PDI Number: GEN002720 > Finding Category: CAT II > Reference: UNIX STIG: 3.16 > Description: The audit system is not configured to audit failed attempts to > access files and programs.

So, they need to have some understanding that you either want a system configured right but failing the SRR's or matching the SRR's but configured wrong. I'd hate to be in your position, but that's where you are. > We are using the rules as found here: > https://fedorahosted.org/audit/browser/trunk/contrib/stig.rules These rules are correct.
