AWS Access Vendor Risk Management isn’t about ticking boxes on a compliance checklist. It’s about protecting the keys to everything you’ve built. A single weak link in a third‑party integration can open the door to unauthorized access, data breaches, and compliance violations. The more AWS services you use, the more vendors touch your infrastructure, the bigger the attack surface becomes.
Every vendor with AWS access has a trust boundary. If you don’t define and enforce that boundary, you invite risk. Managing this means understanding three things: who has access, what they can do, and how you’ll know if that changes. The fastest way to lose control is to assume AWS IAM policies alone will keep you safe without active monitoring and review.
Start with least privilege. For each vendor, grant the minimum AWS permissions needed to do the job. Use IAM roles with short‑lived, auditable sessions. Rotate these credentials and log every request. AWS CloudTrail can show you exactly what’s being done under a given role, but only if it’s configured and monitored.
Audit vendors like you would your own engineers. Review activity logs for unusual actions or spikes in activity. Use AWS Config and Security Hub to enforce rules on every account vendors can touch. Combine them with real‑time alerting so you know about risky changes before they spread.
