IAM

Foundations ✓Platform ✓OpsProjects

Ops · 3 — DevOps, security, scale · ~10 min · Cloud — Security & Observability

What is this?

Identity and Access Management controls who can do what — users, groups, roles, and policies with least privilege.

Why should you care?

CloudVerse banking separates teller, ops, and pipeline identities with no shared admin passwords.

See it live — copy this example

Use AWS/Azure/GCP free tier or local Docker/Kind. Sketches and YAML are meant to be typed and adapted.

# AWS IAM policy snippet — CloudVerse read-only audit
{
  "Version": "2012-10-17",
  "Statement": [{
    "Effect": "Allow",
    "Action": ["s3:GetObject", "s3:ListBucket"],
    "Resource": [
      "arn:aws:s3:::cloudverse-audit-logs",
      "arn:aws:s3:::cloudverse-audit-logs/*"
    ]
  }]
}
# Attach to role CI-AuditReader — not long-lived user keys

What happened?

  • Humans get SSO + MFA; workloads get roles.
  • Regular access reviews and break-glass accounts are documented.

Practice next

  1. Create a group with read-only scope.
  2. Assign MFA on admin roles.
  3. Use role for CI instead of keys.
  4. Add permission boundary on CI role.
  5. Deny unapproved regions via SCP.

Remember

Least privilege. Roles for machines. MFA on humans.

CloudVerse teller access

Branch staff need statement view, not bucket delete.

Outcome: Scoped policy passes audit.
