SOC Construction methodology

Build a verifiable, operable, and continuously optimized SOC system

From environment and log-source analysis through use cases, runbooks, tuning, and acceptance—every stage defines ownership, outputs, and evidence.

Defined deliverables

Continuous operating loop

01
IT environment & log source analysis
Responsible ownerSecurity architect + customer IT owner
Purpose
Establish attack surface, telemetry coverage, and collection constraints before implementation.
Specialist action
Map systems, identity, network zones, cloud accounts, and controls into a prioritized telemetry inventory.
Key outputs
Asset-to-log-source matrix
Coverage gap analysis
Data ownership map
Customer result
A defensible scope with known blind spots and a sequenced onboarding plan.
Acceptance criteria
Inventory ownership confirmed; critical coverage gaps prioritized.
02
Log source onboarding & normalization
Responsible ownerData engineer + platform owner
Purpose
Turn raw events into reliable, searchable security telemetry.
Specialist action
Configure collection, validate fidelity, normalize fields, and enrich with asset and identity context.
Key outputs
Ingestion runbook
Normalized schema mapping
Parsing & health checks
Customer result
Operational telemetry analysts can trust for correlation and evidence.
Acceptance criteria
Collection health, parsing accuracy, and searchable fields accepted.
03
Use-case design
Responsible ownerDetection engineer + risk owner
Purpose
Translate priority threats into detections with clear hypotheses and response intent.
Specialist action
Model adversary behavior, define detection logic and severity, rank by risk reduction.
Key outputs
Use-case backlog
ATT&CK coverage map
Detection specifications
Customer result
A measurable detection roadmap aligned to business risk.
Acceptance criteria
Threat hypothesis, severity, test data, and expected response approved.
04
Runbook design
Responsible ownerIncident lead + business approver
Purpose
Make each alert actionable with consistent decisions and escalation rules.
Specialist action
Design triage, investigation, containment, ownership, and hand-offs across teams.
Key outputs
Response runbooks
Escalation matrix
Evidence checklist
Customer result
Repeatable response that shortens MTTR without losing control.
Acceptance criteria
Decision points, contacts, evidence, and approval boundaries rehearsed.
05
Detection validation & tuning
Responsible ownerDetection engineer + SOC lead
Purpose
Prove detections work in your environment before go-live.
Specialist action
Replay scenarios, measure noise, tune thresholds, and document acceptance evidence.
Key outputs
Validation report
False-positive tune log
Go-live checklist
Customer result
Detections that are both sensitive and operationally sustainable.
Acceptance criteria
Scenario replay passes agreed precision, noise, and latency thresholds.
06
Service acceptance & continuous optimization
Responsible ownerService manager + customer sponsor
Purpose
Hand over an operable SOC and keep improving coverage and process.
Specialist action
Complete acceptance criteria, train operators, and set a cadence for use-case and runbook iteration.
Key outputs
Acceptance package
Ops playbooks
Optimization backlog
Customer result
A living SOC capability—not a one-time project deliverable.
Acceptance criteria
Acceptance package signed; operating cadence and improvement owners assigned.
