Until you learn what and how things are effected learning mode is where you start and then on to interactive or smart mode. If unsure of installation issues with hips and how to adjust, throw it back into learning mode during installation. Rule creation will come with time as you learn. There are manuals on all products if one digs.HIPS is useless if you don't know how to write rules and which rules are needed. I hope this major upgrade includes preinstalled rules so the average user can make use of it.
Changes to HIPS settings should only be made by an experienced user. Incorrect configuration of HIPS settings can lead to system instability.
