Recital 9

The secrecy of TLPT is of utmost importance to ensure that the conditions of the testing are realistic. For that reason, testing should be covert, and precautions should be taken to keep the TLPT confidential, including the choice of codenames that should be designed to prevent the identification of the TLPT by third parties. Should staff members responsible for the security of the financial team be aware of a planned or ongoing TLPT, it is likely that they would be more observant and alert than during normal working conditions, thereby resulting in an altered outcome of the testing. Staff members of the financial entity outside of the control team should therefore only be made aware of any planned or ongoing TLPT where there are cogent reasons and subject to the prior agreement of the test managers, inter alia to ensure the secrecy of the test in case a blue team member has detected the testing.
