Backup is important but, can be dangerous when we cannot track and delete old data. This is where "Cryptographic Erasure" can be useful. It is a simple process, you encrypt the data and when it is time to delete it, DELETE THE ENCRYPTION KEY INSTEAD . Data is as good as deleted.

It has two important advantages:
1. We do not need to restrict ourselves to using a single key that encrypts an entire drive or data set. Instead, we can have as many unique keys as we need, encrypting data at the granularity that serves our purposes

2. Second,it entirely bypasses the issue of tracking data flows. Whether the data resides in a remote data center, in someone else's cloud, is irrelevant. It is sufficient to know where our keys and delete them.

Data security - Boring idea but,data have become a new form and flow of currency. How much have we adapted to this idea?

Customer data, market data, intellectual property, resource consumption data, productivity data, and dozens of other categories are a new form and flow of currency in the data-driven enterprise. However, as data flow has achieved parity with cash flow, the CISO or the CSO has not achieved parity with the CFO.

• Rather than using application names or table or column names, group data at the lowest level into buckets like "high-sensitivity personally identifiable information" or "customer payment information."
• 
  
• Too often companies focus on the relationship between users and application access. This is important, but it doesn't take into account which applications have access to what data, and therefore ignores the direct relationship between users and data
• 
  
• Through new technologies like blockchain, data flows can be recorded directly as they happen, making the resulting audit trail immutable and virtually impossible for the record to be manipulated.

Free additional feature called "Spying on You" (my nick name to the service) without your permission - In windows 7 and 8

I am not surprised, if you are then you are not from this planet


From the article

Back in April, Microsoft released a non-security update for both Windows 7 and 8. This update, 3022345, created a new Windows service called the Diagnostics Tracking service.

The concern with the new Diagnostic Tracking service is much the same as with Windows 10's tracking: it's not clear what's being sent, and there are concerns that it can't be readily controlled.

(good news) Additionally, most or all of the traffic appears to be contingent on participating in the CEIP in the first place. If the CEIP is disabled, it appears that little or no traffic gets sent.
