Fixtext: Add or update the following rules in the "/etc/audit/audit.rules" file: For 64bit architecture: -a always,exit -F arch=b64 -S execve -C uid!=euid -F euid=0 -F key=execpriv -a always,exit -F arch=b64 -S execve -C gid!=egid -F egid=0 -F key=execpriv -a always,exit -F arch=b32 -S execve -C uid!=euid -F euid=0 -F key=execpriv -a always,exit -F arch=b32 -S execve -C gid!=egid -F egid=0 -F key=execpriv Notes: For 32-bit architectures, only the 32-bit specific entries are required. To reload the rules file, issue the following command: $ sudo augenrules --load
