Best Practices for Identity and Access Management (IAM)

  • As part of the “Best Practices” series by Uplatz

 

Welcome to another foundational post in the Uplatz Best Practices series — helping you secure access, manage permissions, and enforce controls in dynamic IT environments.
 Today’s spotlight: Identity and Access Management (IAM) — the gatekeeper of your cloud and application infrastructure.

🧱 What is Identity and Access Management?

IAM is the framework of policies and technologies that ensures the right individuals and systems have the right access to the right resources, at the right time, for the right reasons.

It includes:

  • User identity verification

  • Role and permission assignment

  • Policy enforcement

  • Access auditing and governance

✅ Best Practices for IAM

IAM is the first line of defense in modern security architectures. Here’s how to manage it effectively across cloud, apps, and APIs:

1. Follow the Principle of Least Privilege

🔐 Grant Minimum Necessary Permissions for the Shortest Time
 🧾 Avoid Wildcards (*) in Permissions
 📆 Periodically Review and Revoke Unused Access

2. Use Role-Based Access Control (RBAC) or Attribute-Based Access Control (ABAC)

👥 Group Users by Function and Assign Roles Accordingly
 📌 Use Tags/Attributes (e.g., department, region) for Fine-Grained Access
 🔀 Avoid Granting Direct Permissions to Individual Users

3. Implement Multi-Factor Authentication (MFA)

📱 Enforce MFA for Console, Admin, and Privileged Access
 🔁 Require Second Factors Across All Entry Points
 🛡 Leverage MFA via SSO Providers (e.g., Okta, Azure AD, Ping)

4. Centralize Identity Using Federation and SSO

🌐 Integrate IAM with Enterprise Directory Services (LDAP, AD, etc.)
 🔁 Use Identity Providers (IdPs) With SAML, OIDC, or OAuth2
 🚪 Simplify User Onboarding/Offboarding via HRMS Integration

5. Rotate Credentials and Use Short-Lived Tokens

🔐 Avoid Long-Lived Access Keys and Passwords
 🧰 Use Services Like AWS STS or GCP IAM Workload Identity Federation
 🔄 Set Expiration Policies for API Keys, Tokens, and Secrets

6. Audit and Log All Access Activities

📋 Log User Logins, Role Assumptions, and API Calls
 📊 Use SIEM Tools for Threat Detection and Anomaly Analysis
 🔎 Enable Session Recording for Privileged Access

7. Separate Duties with Admin Boundaries

⚠️ Create Tiered Access Levels (View, Edit, Admin)
 🧑‍⚖️ Enforce Dual-Control or Just-in-Time Access for Sensitive Actions
 🔓 Log All Privileged Access Requests

8. Use Machine Identities with Boundaries

🤖 Create IAM Roles for Applications and Services
 📦 Bind Access to Context (e.g., IP, VPC, Namespace)
 🔁 Rotate Certificates and Machine Credentials Automatically

9. Automate Identity Governance

⚙️ Use Tools Like SailPoint, Saviynt, Azure PIM for Lifecycle Management
 📆 Automate Access Reviews, Certification, and Policy Enforcement
 🔔 Alert on Orphaned Accounts or Excessive Permissions

10. Test IAM Policies Before Deployment

🧪 Simulate IAM Permissions (e.g., AWS IAM Policy Simulator)
 ✅ Use Staging Environments for Policy Validation
 📜 Apply Policy-as-Code for Version Control and Review

💡 Bonus Tip by Uplatz

Identity is the new perimeter.
 Make IAM visible, auditable, and adaptive — because every breach starts with compromised access.
