Security tips?

Making my first bike purchase this week and in prep I want to get all the correct security items to keep it safe! For context, I'll be leaving my bike around the rear of my property, which has a lane access with no through road (for shortcuts etc) and from the road my bike won't be visible whatsoever.. So far I plan on purchasing a Litelok, throttle lock and will be keeping the bike under a cover. Can anyone recommend any further bits of kit that I should consider to keep my precious bike safe!?
