    Exercise: Suppose tomorrow morning a credible group of researchers published a paper that verifiably cracks open the most common encryption algorithm used today, AES. What would you do? How much would it cost you? How long would it all take?

        Probably just reorder ciphers to prioritize chacha and des3.

        3DES doesn't seem like a good idea! What about durable data?

        Step 1 would be to understand the conditions and cost of how AES would be practically broken as stated in that hypothetical research

        Step 2: don’t naively fall back to securing data using only access control if access control is also susceptible to the same AES breakage

        Step 3: check your IR/DR plans for cost benefit trade offs of keeping at-risk parts of your business online (write a plan if you don’t have one)

        All I’m sure of is that 90% of the time would be trying to determine what dependencies I now need to be worried about.
