I enabled the auditd service using the following configuration to trace all user activities (belonging to group ID 555) on RedHat OS:

vim /etc/audit/audit.rules
-a always,exit -F gid=555 -F arch=b64 -S execve
-a always,exit -F gid=555 -F arch=b32 -S execve

vim /etc/audisp/plugins.d/syslog.conf
active = yes
args = LOG_LOCAL6

vim /etc/rsyslog.conf
local6.* @@<IP address>

However, for each executed command, several logs are generated (usually 3 logs), and there isn't any unique log that includes all necessary information, i.e.:

  • Command
  • Username
  • Timestamp
  • Server IP
  • Source IP

Is it possibile to configure auditd to write/forward just one log for each executed command? For instance, if user foobar runs rm -f /root/test.txt, the written/forwarded log should be something like this:

2017-05-10 10:14 <SourceIP> foobar@<DestinationIP> rm -f /root/test.txt

Thanks, Francesco
