Yescertified.com Newsletter - Cloud Security Architecture Decisions You Must Avoid (No. 1)
This one is the start of a new series I am calling "Cloud Security Architecture Decisions You Must Avoid," and I am kicking it off with one of the most common mistakes I see in real AWS environments.
Most teams assume that putting workloads in separate VPCs inside the same AWS account is enough isolation. It is not, and I have seen this assumption create security gaps in production environments that passed design reviews without anyone catching it.
In this issue, I break down exactly why the AWS account is the real isolation boundary, not the VPC, and what a proper multi-account architecture actually looks like on the job.
