Details

If auditing is enabled late in the startup process, the actions of some startup processes may not be audited. Some audit systems also maintain state information only available if auditing is enabled before a given process is created.

Solution

Configure the Ubuntu operating system to produce audit records at system startup.

Edit /etc/default/grub file and add ‘audit=1’ to the GRUB_CMDLINE_LINUX option.

To update the grub config file run,

sudo update-grub
