“Automated systems can allow mistakes, errors, and attacks to be propagated and multiplied in far more damaging ways than manual systems. As the DevOps comedy account @DevOpsBorat says, “To make error is human. To propagate error to all server in automatic way is #devops.” 2 Furthermore, automated tooling is fallible; and as we know so well in the security world, it can be easy for humans to begin to trust in the computer and stop applying sense or judgment to the results. This can lead to teams trusting that if the tests pass, the system is working as expected, even if other evidence might indicate otherwise.”
