Hacking Safeguard 5 Integrity of Information

Government authorities must not add, alter or delete data on the target system, except to the extent technically necessary to carry out the authorised hacking measure. They must maintain an independently verifiable audit trail to record their hacking activities, including any necessary additions, alterations or deletions. Where government authorities rely on data obtained through an authorised hacking measure, they must disclose the method, extent and duration of the hacking measure and their audit trail so that the target person can understand the nature of the data obtained and investigate additions, alterations or deletions to information or breaches of the chain of custody, as appropriate.
