Employee data-theft investigations can be damaged by acting too visibly or too quickly. The goal is to protect the organisation while preserving the logs, accounts and devices that may show what happened.
Preserve before confrontation
If lawful and proportionate, protect relevant logs, cloud records, email data and devices before alerting the subject. Premature confrontation can trigger deletion or destruction of evidence.
Identify likely routes of data movement
Consider USB storage, personal email, cloud storage, collaboration platforms, remote access, printing and file-transfer services. The relevant evidence may sit across several systems.
Coordinate HR, legal and security
Access to employee data should be controlled and justified. Technical investigators should work within the organisation’s legal authority, policy and employment process.
Keep an action log
Document account restrictions, device collection, log exports and any contact with the employee. Response activity itself becomes part of the case chronology.
- Endpoint and EDR logs
- USB and removable-media history
- Cloud and file-access logs
- Email and collaboration records
- Company devices and relevant backups
- Employment and access-control timeline
- Reassigning or wiping the user device before preservation
- Browsing the device informally
- Deleting accounts before mailbox and cloud data is retained
- Collecting more personal data than the investigation requires
