Jim Hacker: How am I going to explain the missing documents to The Mail?

Sir Humphrey: Well, this is what we normally do in circumstances like these.

Jim Hacker: (reading) This file contains the complete set of papers, except for a number of secret documents, a few others which are part of still active files, some correspondence lost in the floods of 1967… Was 1967 a particularly bad winter?

Sir Humphrey: No, a marvelous winter. We lost no end of embarrassing files.

The government official who insisted that commercial AWS/GCP/Azure couldn't possibly be trusted with keeping the information will be keeping their head low for a few days then... "The Interior Ministry explained that while most systems at the Daejeon data center are backed up daily to separate equipment within the same center and to a physically remote backup facility, the G-Drive’s structure did not allow for extern…

The issue here is not refusing to use a foreign third party. That makes sense. The issue is mandating the use of remote storage and not backing it up. That’s insane. It’s like the most basic amount of preparation you do. It’s recommended to even the smallest of companies specifically because a fire is a risk. That’s gross mismanagement.

Yeah, the whole supposed benefit of an organization using storage the cloud is to avoid stuff like this from happening. Instead, they managed to make the damage far worse by increasing the amount of data lost by centralizing it.

Samsung's software is generally terrible; they're decent at hardware, not software.

I was going to say, Samsung anything immediately makes me assume the software is awful. With a dose of zero privacy, cloud enabled door-knob or something.

The hardware is highly engineered to fail at a specific time window after the warranty is over.

If you (as the SK government) were going to do a deal with " AWS/GCP/Azure" to run systems for the government, wouldn't you do something like the Jones Act? The datacenters must be within the country and staffed by citizens, etc.

One of the lessons I learned from my Network Administration teacher was that if you're ultimately responsible for it and they say no backups?

You tack on the hours required to do it yourself (this includes the time you must spend actually restoring from the backups to verify integrity, anything less can not be trusted). You keep one copy in your safe, and another copy in a safety deposit box at the bank. Nobody ever has to know. It is inevitable that you will save your own ass, and theirs too.

Shit happens.

Backups should be far away, too. Apparently some companies lost everything on 9/11 because their backups were in the other tower.

They deserved to lose everything... except the human lives, of course.

That's like storing lifeboats in the bilge section of the ship, so they won't get damaged by storms.

As of today, there's no way to prove the security of any available cryptosystem. Let me say that differently: for all we know, ALL currently available cryptosystems can be easily cracked by some unpublished techniques. The only sort-of exception to that requires quantum communication, which is nowhere near practicability on the scale required. The only evidence we have that the cryptography that we commonly use is ac…

One-time pad is provable secure. But it is not useful for backups, of course.

OTP can be useful especially for backups. Use a fast random number generator (real, not pseudo), write output to fill tape A. XOR the contents of tape A to your backup datastream and write result to Tape B. Store tape A and B in different locations.

Funnily enough, Germany has laws for where you are allowed to store backups exactly due to these kinda issues. Fire, flood, earthquake, tornadoes, whatever you name, backups need to be stored with appropriate security in mind.

Germany, of course. Like my company needs government permission to store backups.

No it doesn’t. It does however need to follow the appropiate standards commensurate with your size and criticality. Feel free to exceed them.

Of course you'd encrypt the data before uploading it to a third party, but there's no reason why that third party should be under control of a foreign government. South Korea has more than one data center they can store data inside of, there's no need to trust other governments sigh every byte of data you've gathered, even if there are no known backdoors or flaws in your encryption mechanism (which I'm sure some gove…

There is a reason that NIST recommends new encryption algorithms from time to time. If you get a copy of ALL government data, in 20 years you might be able to break encryption and get access to ALL government data from 20yr ago, no matter how classified they were, if they were stored in that cloud. Such data might still be valuable, because not all data is published after some period.

The reason is because better ones have been developed, not because the old ones are "broken". Breaking algos is now a matter of computer flops spent, not clever hacks being discovered.

When the flops required to break an algo exceed the energy available on the planet, items are secure beyond any reasonable doubt.
