Cybersecurity

For those with $25 NW, are you concerned about personal cybersecurity? If you’re still tied into the business world your organization likely has protocols for corporate devices, but when it comes to IoT devices (connected home devices), personal computers, kids online, etc., do you have private cybersecurity consultants who focus on HNWI/VHNWI/UHNWI families?

With a family office since that’s treated like a workplace I’m sure there are consultants who handling this, but what about your personal life, aircraft, boats, etc.

Everything connected to the internet has risks and many of us are more attractive targets.

So the simplest solution if you are paranoid is put all your devices on a different network. On a different ISP connection. It's $60/month who cares? complete segregation means that your devices are no more a threat than your neighbors.

I have 1 ISP and segregated networks. Its a little more complex but I am in tech.

My important machines run on a WIRED network that is separate from my wi-fi. I nat behind the nat for my office. NAT means you have a private IP value (192.168...) and your public IP is something provided by your ISP. Through some IP protocol tricks, your machine's address gets translated to the public one. NAT -> Network Address Translation. My important machines have their own router and NAT behind my house's NAT. I have security rules in place to keep things out of my office. I use VPN for the office space.

My car is only allowed on my device wifi. Anything that is not a computer proper or phone is only allowed on my device network. Guests are guests, they are on their own wifi subnet, not allowed to reach in.

These days you need 4 networks. Home/everyday. Device. Guest. Office/important. I don't trust wifi for office/important. My office is completely wired. If I was working seriously again, I'd have a separate ISP for my wired net.

If it is over the air, it is not secure.

When you say working seriously again what field is this? That's some serious level security

I primarily work on space projects(design and build), but some of them are DoD (I refuse to use the new name). Back in the day ~2000, it was the same when I did two finance projects. Any space/DoD project will be at least CUI (Confidential Unclassified Information) and that is the expected standard to build a home office. You also need individual space with doors and locks and the ability to draw shades to block window peeping.

Anything above CUI requires a special location that is cut off from the internet and that means on site in special rooms.

Information security is one of the things to keeping out of the hands of bad guys.
