Incident Response Orchestration
MTTR falls quarter-over-quarter
The first 30 minutes of an incident determine the outcome; those 30 minutes are also when the response is most chaotic. Analysts are IMing each other for context, someone else is trying to page the on-call, a third person is manually gathering system state before anyone has decided what the incident is. By the time IR has coordinated who does what, the attacker has been through the environment for hours. The playbook exists in Confluence; nobody reads it during the incident.
An hour-by-hour walkthrough.
Step by step.
- 01
Open the incident + spin up the channel
On high-severity alert, open incident channel with the alert detail. Page on-call. Set incident status. Naming convention consistent across incidents for easy retrieval.
PagerDuty · Slack · Teams · Incident naming convention - 02
Gather context in parallel
Every relevant plane at once: identity, endpoint, network, code, infra, application logs. Enrichment finishes before the analyst opens their laptop.
Okta · CrowdStrike · SentinelOne · SIEM · Cloud logs · Application logs - 03
Pre-contain per playbook config
Playbook-configured pre-containment actions (isolate device, disable session, revoke tokens) execute immediately with pre-approved authority. Analyst overrides on arrival if wrong; time is more valuable than a rollback.

Orchestrate the analyst-led response
Every containment / eradication / recovery action surfaced with one-click approve. Executes on approval; verifies success; updates the timeline. Every stakeholder briefed as their role becomes relevant.
Slack · Teams · Approval flow · Stakeholder registry - 05
Post-incident evidence + after-action
Timeline, evidence bundle, IOC list, affected-entity list, containment actions, timeline of stakeholder briefings. Post-incident review draft with root cause hypothesis + remediation recommendations.

Answers about this playbook.
Isn't pre-containment risky if the alert is a false positive?
Pre-containment actions are configurable per playbook: high-severity + high-confidence detections isolate; medium severity gathers context only. False-positive rollback is one action (unisolate, re-enable session). Time cost of false-positive containment is minutes; time cost of not containing a real incident is hours.
How does it handle multi-system incidents (endpoint + cloud + application)?
Correlation across planes. Sig maintains one incident with per-plane sub-timelines. Containment actions across planes coordinate (isolate device + revoke cloud credentials + expire application session together).
What about incidents that need external communication (customer, regulator)?
Communication playbook triggers per severity + data-class. Draft notifications to affected parties, legal + comms review, tracked send. Regulator notifications on the regulator's clock (72 hours GDPR, etc.); Sig calendarises the deadline.
How does this coordinate with our incident-command process?
Sig runs the operational orchestration; incident commander runs the strategic decisions. Sig provides the situation report; IC directs actions. Roles complementary, not overlapping.
What if the on-call analyst is unreachable?
Escalation ladder: backup on-call at 5 minutes, security manager at 10, CISO at 20. Pre-containment continues on playbook authority; analyst-required actions wait until human is engaged.
