The forethought of design is impressive. The strategic cybersecurity cycle incorporates Prediction, Prevention, Detection, and Response. You are showcasing the Predictive skills necessary to empower more effective Prevention, faster Detection, and more efficient Response (recovery in this case).
I have been worrying about the design of Steem security controls for a few days. Cryptocurrencies, in fact all fiat currencies, are founded on trust. As we have seen lately, lack of proper security oversight and planning can cause a serious impact to trust, which creates a detrimental cascading effect.
So it is good to hear where your head is at and what you have done to mitigate the risks. Well done sir!
Oh, and on a side note, I think you inadvertently answered my main question about Steemit security I had posted here: https://steemit.com/steemit/@mrosenquist/crytpocurrency-is-a-target-for-hackers-is-steemit-ready
So thanks for that!
