Security operations

A practical managed detection and response operating model.

Managed detection and response depends on useful evidence, clear escalation paths, and a shared understanding of what needs investigation first.

Prioritise useful telemetry

Begin with systems, identities, and activity that matter to the organisation rather than attempting to collect every possible signal.

Known gaps should be visible so leaders can decide whether additional coverage is warranted.

An investigation moves faster when contacts, business context, technical owners, and escalation expectations are already known.

The operating model should make clear what information is needed for different levels of response.

Service reviews should look beyond individual alerts to recurring control gaps, high-friction investigations, and improvement opportunities.

Those themes provide a practical link between security operations and longer-term risk reduction.

Decision tools

Name the systems, identities and activity that require prioritised detection.
Define investigation, notification and escalation ownership for each severity path.
Agree what business and technical context must accompany an escalation.
Set a review rhythm for coverage gaps, recurring investigations and improvement actions.

A telemetry inventory showing sources, owners, retention and known collection gaps.
Critical-service, asset and identity records used to set investigation priority.
Existing alert, triage, escalation and incident-management procedures.
Named contacts and decision paths for the agreed operating periods.

Collecting more telemetry without agreeing which investigations it must support.
Escalating technical detail without the owner or business context needed for a decision.
Leaving coverage gaps and repeated investigation friction outside the service review.
