Guidelines for good red teaming

  1. Plan red teaming from the outset. It cannot work as an afterthought.
  2. Create the right conditions. Red teaming needs an open, learning culture, accepting of challenge and criticism.
  3. Support the red team. Value and use its contribution to inform decisions and improve outcomes.
  4. Provide clear objectives.
  5. Fit the tool to the task. Select an appropriate team leader and follow their advice in the selection and employment of the red team.
  6. Promote a constructive approach which works towards overall success.
  7. Poorly conducted red teaming is pointless; do it well, do it properly.
