Backups for ransomware
There is no dearth of advice about protection from ransomware and it always mentions (glibly) the importance of making backups and keeping them offline. But the data may be crypto-locked before it gets backed up.

The key is to verify that the (daily) backups are clean, as a means of early ransomware detection and preventing good backups from being over-written.  Nowhere do I see detailed advice on verifying backup integrity:  a) How do you verify that a backup is not encrypted? Can it be automated or would it need a human to detect encrypted data?  b) Keep in mind databases, Exchange, Active Directory and data in non-readable formats.

One solution to automating the integrity check is to seed your data with known static data- static files, database records, a mailbox, etc. Only the seed data could be restored and checked against the expected value.  But this would be a custom solution, not something off the shelf as far as I know.  In fact, seed data could be copied (low-level copy to bypass ransomware hooks into the OS) to another system and checked against expected values even hourly, as an early warning system for ransomware.  Has anyone tried this approach?

Re: weighing in
Indeed, I asked the CFO this question, and he was totally stunned by it.  He just told me a less graceful version of "I'd trust your recommendations" -- which is nice, but tells me nothing about the financial or risk-management side of things from his office's perspective.  Which apparently means they wanted me to do that part of it too.  CFO Jr.

Okay.  Fine.  That's cool.

But, you know, like, pay me for it maybe?  ;)

Re: weighing in
Well, it can't *always* be the case -- by virtue of what "below average" means.  ;)

But yes, I get the "Murphy's Law-ness" of it all.

In general, I've found that the companies that have better business plans, better business models, and better product or service quality tend to have better approaches to data protection.

(Emphasis on "tend")

I assume because what we have here is a public data.

This is quite common, there is no real budget for security, it comes in after the attacks.

I really do not have an answer but this is the reality. Just one step at a time. Unless we start using robots.

Unfortunately this is  always the case. They want you to do more work with less salary.

I would like to know why Darkreading/Information Week still to this day does not offer a secure member login? I suppose this is also a risk for any Authors that post articles to the site as well.
