The protection and security of tools or documents requires at the very least a good, strong cabinet door and a good hinge for cabinet doors. With strong metal or wood to keep something out of reach for others, at least if we're speaking of a cabinet with a proper lock rather than a simple cupboard or something similar which is simply meant to contain things for safekeeping rather than keeping it out of reach from others. Usually, the extra protection is for cabinets within an industry or some other workplace where you want to some items, papers, or equipment to be kept out of the hands of people without the right key or access. Even the hinge for cabinet doors will matter for the safety and security of such things, to avoid someone with intent to break into it through brute force.
There's very little use for a key and lock if the rest of the cabinet is too fragile and easy to get into, so making sure that what you get is durable and of good quality is an important part of designing access solutions or acquiring cabinets and containers. The materials and the handle for cabinet doors can and should be planned out in advance for whatever you're going to use it for, keeping the environment in mind so that it can remain sturdy and last longer without degrading from time so that you will not repair or must get a new cabinet for yourself.
