With real property, you can't get sued for negligence just for having lax security. You can incur liability if somebody gets onto your property and hurts themselves (the particulars of which I'm not familiar with since IANAL), and you may lose some protection for property damage/loss, but the standard for that is also very much in favor of the property owner.
