Secure SDLC control plane

The Secure Software Development Lifecycle for Distributed Teams is the most operationally specific source. Its thesis is that security failures in distributed delivery are operating-model failures caused by gaps in tooling, ownership and enforcement.

Phase controls

Phase	Minimum control	Evidence	Failure to prevent
Planning	security requirements, risk classification, asset/data inventory	approved requirements and risk record	building an insecure design into scope
Design	threat model, trust boundaries, abuse cases, architecture review	model, decisions and accepted risks	unexamined attack paths
Development	secure coding, peer review, SAST, SCA, secret scanning	PR, scan results and remediation	defects and leaked credentials
Build	reproducible build, dependency validation, policy gates	build provenance and gate result	tampered or untraceable artifacts
Test	DAST/IAST, API and authorization tests, regression tests	test reports and triage	runtime flaws escaping static checks
Deploy	approval, IaC review, rollback plan, environment parity	deployment record and rollback owner	uncontrolled production change
Operate	monitoring, vulnerability intake, incident response, patch SLAs	alerts, tickets, postmortems	persistent exposure and slow recovery

Ownership model

Every finding needs an owner, severity, due date and escalation path. Every exception needs an approver, rationale, expiry and compensating control. Every rollback needs a named decision-maker. The blog's strongest insight is that an unowned finding is an architectural defect in the process.

Distributed-team design rules

• Use shared CI/CD templates instead of team-specific security folklore.
• Standardize minimum controls but allow risk-based extensions.
• Put remediation and rollback ownership in the RACI.
• Track control coverage and remediation time across teams.
• Make the secure path the easiest path.
