🔐 CloudCSF Day 3
Control #2: Identity & Access Management – Enforce Least Privilege Like a Pro
“Every extra permission is a future breach waiting for an opportunity.”
⚠️ The Access Explosion Nobody Sees
In today’s cloud-first world:
- A developer creates an IAM role with full admin rights “just for testing.”
- A former intern still has access to production databases.
- A service account with elevated privileges hasn’t rotated keys in 3 years.
🚨 Identity sprawl and over-permissioning are silent killers of cloud security.
The biggest breaches of the last decade?
➡️ They started with over-privileged access.
🔍 What Is IAM & Least Privilege?
IAM (Identity and Access Management) is the gatekeeper of your cloud.
It ensures that:
- The right people (or machines)
- Have the right access
- To the right resources
- For the right time — and nothing more.
🔐 Least Privilege = Give only the access needed to perform the task — no more, no less.
✅ 5-Step Control Test – IAM (Cloud Edition)
- List All Human + Machine Identities
- AWS IAM, Azure Active Directory, GCP IAM
- Include service accounts, roles, federated identities
- Scan for Admin Rights + Wildcards
- Find
*:*permissions - Identify
AdminAccess,Owner, orFullAccessroles
- Find
- Test Identity Age + Usage
- Who hasn’t logged in in 90 days?
- Which roles haven’t been used?
- Review Access Policies
- Inline vs. managed policies
- Are they scoped to resources or overly broad?
- Enforce MFA + Key Rotation
- Identify users with no MFA
- Rotate keys older than 90 days
🎯 IAM Maturity Levels
| Level | Description |
|---|---|
| 🚫 0 – Open Access | Most users have full admin |
| ⚠️ 1 – Reactive | Users removed manually after issues |
| 🔁 2 – Scoped Access | Roles defined, but not reviewed |
| 🔐 3 – Enforced Least Privilege | All users/roles reviewed quarterly |
| 🛡️ 4 – Automated IAM | Just-in-time access, identity lifecycle governed |
➡️ Where do you stand?
🛠️ Tools You Can Use
- ✅ AWS IAM Access Analyzer, Azure PIM, GCP IAM Recommender
- ✅ Cloudsplaining, PMapper (for AWS IAM graph visualization)
- ✅ Audit logs + IAM credential reports
- ✅ CIEM tools: Sonrai, Ermetic, Wiz
💡 CloudCSF Pro Tip
“Access once granted is rarely revoked — unless you make it a culture.”
