After an incident, establish the facts that support recovery
First secure systems, preserve relevant records and avoid premature conclusions.
Combine internal records with public context
A website outage, compromised mailbox or unusual access attempt first requires an operational response. Responsible staff should contain the exposure, preserve records that may disappear and identify which providers to engage. OSINT can supply public technical context but cannot replace authorised examination of affected systems.
Internal logs may establish an event time, while vendor notices, domain changes and published outages offer wider context. Correlation should be cautious: simultaneous events are not necessarily related. A failure, configuration mistake and malicious action must be distinguished before classifying an incident. Intrusive analysis requires the right scope and skills.
Practical checkpoints
- Prioritise containment and business continuity.
- Preserve relevant logs without altering originals.
- Distinguish timing correlations from proven causes.
- Document corrective actions after recovery.
Discuss a technical or training requirement
Describe your technical environment, documentation question or prevention needs. The scope of any service is agreed in advance.

After services recover, the review asks what enabled the incident, what limited its effects and what delayed restoration. Improvements may involve access controls, backups, documentation or supplier communication. Where the situation exceeds routine IT diagnosis, the organisation should engage appropriate specialists and, where necessary, legal advisers or competent authorities.
