Being a less attractive target than your neighbours, either by being a bigger hassle or by looking like there's nothing worth stealing.

Reinforce your doorframes and window frames, preferably with steel. The dinky pine wood frames of residential doors and windows are hilariously easy to kick in, and the thickest steel door and the meanest window bars in the world won't mean much when an attacker can simply kick them out of the frame with a minimum of effort.

You will probably find that doing this is in fact deemed illegal by at least one entity in your local hierarchy of state/county/municipality. I'll give everyone three guesses as to why.

Judging by the link in the OP, the concern is the possibility of ICE or other federal agents breaking in. It's not the same as dealing with a random intruder. About the best you can hope for is to slow them down, maybe giving you time to get away or for legal assistance and the media to arrive.

Given that, I'd concentrate on making the house more sturdy: steel framed doors, steel rolling garage door, properly installed security bars/screens on windows and so forth. And maybe start with a solid masonry house.

Probably not realistic for most people, but then a few years ago I wouldn't have considered the risk realistic either, and here we are.

As a locksmith, I can tell you what I tell my paranoid customers. Buying the greatest lock in the world doesn't do shit if you still have first floor windows.

Layers.

Plant something with thorns or pointy leaves to block easy access to windows. Even better as a hedge around the whole property. Anti break film on windows. Heavy duty exterior doors. Motion sensing lights. Cameras, +1 for cameras with built in lights that can recognize people and automatically turn on.

Every layer should either strengthen, increase risk of being caught, or make access painful. They will go towards easier targets.

Gravel around your house. Bad guys don't want to be heard.

Exterior lighting everywhere, bad guys don't want to be seen.

Provide universal health care, low cost.of living to income ratio, free higher education, strong community building, and walkable cities.

Have you seen the film Home Alone 2?

Having two locks including a proper deadbolt with a decent type of key. You want a deadbolt that goes deep into the door frame, not a cheap one that barely hits the strike plate. That and locking windows with window film will keep most people out.

Nothing will keep someone out who really wants to get in. You just need to make the hassle greater than their desire to get in.

Lesson from South Africa: by the time they are at your door it's too late. Perimeter fencing, preferably a 2m high wall with razor wire AND electric fence on top (including on gate). Garden: floodlights, motion sensing alarms, beams, AI cameras. All doors and windows: bars and security gates. Inside: separate living and sleeping area with lockable gate in the hall between. Panic buttons..

None of that is going to stop a legal intrusion, each just buys you time before the paid security company arrive with guns to chase away intruders. Given time, any determined attacker will get in eventually..

Home Alone has some solid ideas

If you asking how you secure your residence against ICE…good luck with that. They have legal access to an expansion of the Patriot Act for warrants, and they have toys they’d love to use against any home security. All that physical security is going to do is give them probable cause.

The ONLY way to stop someone who really really really wants into your house from entering your house. Is to not have a house.

In response to law enforcement, make sure you know your rights. If they are truly just conducting door to door operations, they would have no legal basis to enter your house. That might not stop them from fabricating some exigent circumstances (legally defined term that would come into play). But unless you open the door and/or invite them in, they can't legally come in.

There are two levels to this:

1. Do you want to stop someone on the outside from gaining entry?

2. Or do you mean stopping someone AFTER they have gained entry?

If 1 - The usual steps, cameras, lights, barriers to entry, no trespassing signs, that kind of thing. In our case, an automated light worked wonders. Dude walked up our driveway, took one step on the lawn, lights came on, and he went home to re-think his life choices.

For 2, if they have already gained entry, know your local laws on lethal force, duty to retreat, stand your ground, and castle doctrine. Easy to Google - "your city/state" + any of those terms.

In MY state, lethal force is only allowed in 3 circumstances, one of those three is burglary.

"Committing or attempting to commit a burglary in a dwelling"

Were I in a less secure neighborhood: Deadbolt, second deadbolt, dog.

Better door, better lock, better strike plate, longer and stronger screws. The rest can be visual deterrents like cameras, window sensors, and proximity lights that make them visible to neighbors and drivers.

The goal is to make your house a slightly harder target than some other house. Go for the easy stuff first like keeping the property well lit, lock your windows and doors. Close your blinds so valuables cant be seen from outside. Something people dont often talk about is getting friendly with your neighbors. They can be an extra set of eyes out for anything suspicious.

If you're willing to spend some money, plant thorny bushes under vulnerable windows. Get a security system, or just put a fake security system sign in your yard. Put up cameras.

An easy one is to replace the screws for your door hinges and deadbolt with nice, long, 3 inch screws in place of the tiny ones that are usually used. They longer screws will extend into the wall studs instead of only the doorframe. Makes it harder to kick in. You can also buy metal strips for reinforcing your door jam that aren't too expensive.

One access point I think people tend to overlook are garage doors. I put mine on remote switches so I can completely power them off at night. Even if someone got my garage door opener or one of those spoofers, they wouldn't be able to open the doors.

Just a few ideas off the top of my head.

If you just want to prevent opporitunistic break ins then you just need to make your house a less appealing target than the neighbors. A sturdy door, motion activated lights, and a dog can do that easily enough. If you want to go the extra mile then put up a few cameras. The cameras don't even need to be real. I used to work for a fortune 500 company that made extensive use of fake cameras on their properties. The trick there was that they also had a few identical looking real cameras as well so unless you had insider knowledge, you would have to consider all of the cameras real.

Now if you want to stop someone who is determined to break into your house specifically then that gets trickier. You will never stop someone determined enough so the goal is to just make the process of breaking in as noisy and difficult as possible. You will want a good and properly mounted deadbolt on all your doors. By properly mounted I mean, throw out those dinky 1" screws that came with the deadbolt plate and mount that plate with some big old 4" long screws. A deadbolt plate just screwed into the doorframe does little good. But if you screw that thing clear through the door frame and into the (preferably doubled up) stud behind it, then bashing in your door goes from requiring a swift kick to requiring a ram or a sledge. Also, if you don't like the look of bars on your windows, you can just apply huricane laminate to your windows instead. It's a film that is designed to be applied to windows in huricane prone areas to prevent debris from flying through the windows. It also makes smashing in your windows a tremendous pain in the ass. The glass will still break but it will all be held in place by the film similar to a broken car windshield. It is possible to get through but it is a very time consuming and conspicuous process. Finally, cameras. Now that you've made it a pain to get through your doors and windows, you want to be sure that anyone who would still be willing to put in the effort also knows that they're being watched the entire time they're breaking in. Yes you can still smash in a door with a proper deadbolt or smash in a laminated window but few people are willing to spend that much time on camera being recorded committing a crime. Beyond those measures your walls become the weak point and there isn't much you can do about that without rebuilding the house.

Oh right. Can you get some pet geese for the outside? Nothing louder than geese

Adopt a pair of Doberman Pinscher's that were trained Elite Spec Ops.

Not really much, tbh.

Decent quality door locks
Clear line of sight from the street to likely entry points
Loud alarms so if they do break in they're not likely to stay long

If someone wants to get into a house, there isn't much you can do to stop them unless you're rich and can afford exotic shit like bullet proof glass windows and thick metal reinforced doors.
All to can really do is discourage crimes of opportunity by making them seem like bad opportunities.
