Preserve relevant technical records before they disappear

Create a simple handling register

Application logs may rotate, emails can be deleted and web pages change during normal operations. Following an incident, teams should quickly identify relevant records, decide who is authorised to preserve them and avoid unnecessary handling. Collection must remain proportionate to its purpose and consistent with confidentiality obligations.

For each item, record its source, collection date, receiving role, storage location and subsequent handling. Preserve originals where feasible and perform analysis on working copies. Cryptographic hashes help check integrity against a reference, but do not replace a documented handling process.

Practical checkpoints

• Identify relevant records and retention periods promptly.
• Use working copies for technical review.
• Restrict access and transfers to authorised people.
• Document operations that may change the files.

Support the next stage of response

Clear documentation helps subsequent work by specialists, insurers, legal advisers or competent authorities. Unprotected copies containing personal data or business secrets must not circulate freely. Preservation should not delay urgent steps to secure exposed accounts or systems. Teams need a practical balance between operational recovery and record integrity.
