Identity and Access Management (IAM) Design for Cloud Environment

Objective

To design a secure and scalable IAM model that minimizes unauthorized access and reduces identity-related security risks in a cloud environment.

---

Role Definition

The following roles were defined:

Administrator

• Full infrastructure access
• MFA enforced
• All actions logged and audited

Developer

• Access limited to application resources
• No infrastructure-level permissions
• No access to security logs

SOC Analyst

• Read-only access to logs and monitoring systems
• No modification privileges

---

Access Control Strategy

• Role-Based Access Control (RBAC)
• Separation of duties across roles
• No shared user accounts
• Least privilege enforced for all roles

---

Authentication Strategy

• Multi-factor authentication for privileged roles
• Strong password policies
• Centralized identity management

---

Risk Mitigation Mapping

Risk	Control	Outcome
Credential theft	MFA	Reduced account compromise
Privilege abuse	RBAC	Limited blast radius
Insider threat	Logging and audits	Improved accountability

---

Conclusion

A well-designed IAM strategy significantly reduces unauthorized access risks while maintaining operational efficiency in a cloud environment.
