Recital 24

The TLPT should be used as a learning experience to enhance the digital operational resilience of financial entities. In that respect, the blue team and testers should replay the attack and review the steps taken to learn from the testing experience in collaboration with the testers. For that purpose and to allow for adequate preparation, the red team test report and the blue team test report should be made available to all parties involved in the replay activities, prior to conducting any replay activities. Additionally, a purple teaming exercise, in the closure phase, should be carried out to maximise the learning experience. Methods that may be used for purple teaming in the closure phase should include discussions of alternative attack scenarios, exploration on live systems of alternative scenarios or the re-exploration of planned scenarios on live systems that the testers had been unable to complete or execute during the testing phase.
