Design DevSecOps security triage and response process
Implementation Effort: Medium – Defining triage ownership, severity and exploitability priorities, response timelines, and finding tracking across scanning tools requires coordination between security and engineering teams. User Impact: Low – Establishing the triage and response process is a security and engineering-leadership activity; end users are not affected. Lifecycle Stage: Govern
Overview
Define a DevSecOps security triage and response process that assigns owners, prioritizes findings by severity and exploitability, and tracks each finding through remediation or approved risk acceptance.
Enabling code scanning, dependency scanning, secret scanning, and infrastructure-as-code scanning produces a continuous stream of security findings. Without a defined triage and response process, those findings accumulate as unaddressed alerts, creating noise that developers learn to ignore and security debt that grows with every sprint. A security triage process establishes who reviews findings, how severity and exploitability determine priority, what the expected response timelines are, and how findings are tracked from detection through remediation or accepted risk.
The triage process must account for the different finding types that DevSecOps tooling produces. Code scanning alerts from CodeQL require a developer who understands the application logic to assess whether a flagged data flow is truly exploitable. Dependency alerts from GitHub Dependabot or GitHub Advanced Security for Azure DevOps can require package upgrades that introduce breaking changes and need testing before release.
Secret exposure alerts demand immediate rotation and scope assessment regardless of severity classification. Infrastructure-as-code findings usually require template changes and redeployment. Each category has different ownership, remediation timelines, and escalation paths, so the process should define severity-based SLAs and assign clear accountability.
Organizations without a triage process do not lack security findings — they lack the operational discipline to act on them. Findings pile up, developer trust in the tooling erodes, and genuine critical vulnerabilities get lost among hundreds of unreviewed alerts. A defined triage model closes the gap between detection and remediation so security signals are evaluated, assigned, and acted on instead of simply collected. A defined triage and response process supports Assume breach by ensuring the organization can rapidly evaluate, prioritize, and act on the findings that reveal exploitable weakness rather than allowing them to accumulate unaddressed.
