TL;DR: SDLC supply chain attacks now target developer endpoints, VCS, CI/CD, registries, and production because point controls leave gaps between layers, according to StepSecurity. The practical lesson is that defenders need coordinated coverage across the software factory, not isolated checks that attackers can route around.

Questions worth separating out
Q: What breaks when SDLC security is split across separate tools?
A: Attackers use the seams.
Q: Why do privileged developer and pipeline identities increase supply chain risk?
A: Because they can write code, approve changes, publish artefacts, or trigger deployments with minimal friction.
Q: How do security teams know whether CI/CD risk gates are actually working?
A: Look for enforced outcomes, not just alert volume.
Practitioner guidance
- Inventory identities across the software factory Map human users, service accounts, CI/CD tokens, signing credentials, package publishing rights, and AI coding agent permissions across developer endpoints, version control, build systems, registries, and production.
- Enforce policy before code can progress Block newly published or untrusted packages, require provenance checks, and restrict workflow permissions so unreviewed code and third-party automation cannot reach build or deploy stages.
- Add runtime detection to build infrastructure Monitor CI/CD processes, file access, and network egress for anomalous behaviour so compromised jobs can be detected while they are executing, not only after artefacts ship.
What's in the full article
StepSecurity's full blog post covers the operational detail this post intentionally leaves for the source:
- Dev Machine Guard behaviour for endpoint monitoring, AI coding agent security, and MCP server monitoring in real developer environments.
- Cooldown and compromised-package checks that gate dependency adoption before a pull request is merged.
- Harden-Runner runtime monitoring patterns for CI/CD process, file, and network controls.
- Artifact and registry monitoring details for preventing compromised packages from entering the supply chain.

SDLC security is now an identity governance problem as much as a software integrity problem. The article’s core point is that modern supply chain attacks travel on trusted identities, not just on vulnerable code. Developer accounts, build tokens, registry permissions, and automation credentials all become security boundaries when attackers target the software factory. Practitioners should treat every SDLC control plane as an identity boundary with its own lifecycle, privilege, and audit requirements.
A question worth separating out:
Q: Should organisations treat AI coding agents like privileged software identities?
A: Yes. If an AI agent can install code, access secrets, or modify repositories, it is functionally acting as a privileged non-human identity and should be governed that way. That means task-scoped access, explicit boundaries, and monitoring of its downstream actions, especially when it can touch build and release systems.
