Outside of regular order, cybersecurity will tend to be flailing, spasmodic, political, and threatening to privacy and liberty. We should not want a system of Soviet-style regulatory dictates for that reason—and because it is unlikley to produce better cybersecurity.
The better systems for discovering and responding to cybersecurity risks are already in place. One is the system of profit and loss that companies enjoy or suffer when they succeed or fail to secure their assets. Another is common law liability, where failure to prevent harms to others produces legal liability and damage awards.
