Mains Strategy

Open with the public service at risk, then identify its dependencies and possible consequences. An online hospital system may need both confidentiality of records and rapid availability to authorised staff. This framing prevents a generic answer from recommending maximum restriction without considering service continuity. The appropriate control depends on the threat, required access and operational setting.

Organise the response through governance, technical protection, detection, incident handling and recovery. Give each recommendation a purpose: access reviews reduce unnecessary privilege; segmentation limits spread; monitoring supports timely response; tested backups provide evidence of recoverability. Include responsible teams and escalation arrangements rather than assuming tools operate themselves.

Use a hypothetical failure to test the proposal. If a backup exists but restoration has not been exercised, recovery time and completeness remain uncertain. If alerts are collected without triage, detection may not produce action. Conclude with regular review and exercises tied to essential-service outcomes, while avoiding unsupported claims that one product or certification guarantees security.
