☁️ Cloud Security Implementation: IAM Hardening in AWS & Azure

🔒 Least Privilege Access | NIST 800-53 Compliance | Zero Trust Architecture

This project presents a complete IAM (Identity and Access Management) implementation across AWS and Azure, focused on enforcing least-privilege access, aligning with NIST 800-53, and integrating Zero Trust Architecture to harden cloud environments.

📌 Project Overview

This initiative strengthens access control mechanisms within cloud infrastructure by:

• Reducing excessive permissions through precise IAM policy configurations
• Integrating Zero Trust principles for resource-level authentication
• Enhancing compliance alignment with frameworks like NIST 800-53

---

🛠️ Key Features

✅ IAM Policy Configuration

• Configured IAM policies for 50+ AWS S3 buckets and Azure VMs
• Enforced least-privilege access across user roles and services

✅ Vulnerability Reduction

• Achieved 30% reduction in access-related vulnerabilities (Qualys Scan Reports)
• Blocked public access to sensitive buckets, services, and resources

✅ Compliance Alignment

• Aligned with NIST 800-53 Access Control (AC-2, AC-3, AC-6, AC-17, AC-24)
• Implemented automated IAM audits and access lifecycle management

✅ Zero Trust Architecture

• Enforced MFA, just-in-time (JIT) access, and conditional resource-level controls
• Integrated Privileged Identity Management (PIM) for Azure elevated accounts

---

📊 Security Dashboard Highlights

• Real-time visualizations of access control metrics and IAM logs
• IAM audit logs showing access attempts, denied requests, and policy changes
• Vulnerability heatmaps for AWS S3, Azure VMs, and RBAC configurations

📂 Case Studies

🧾 S3 Bucket Exposure (AWS)

A prior misconfiguration allowed public read access to sensitive PII data. Remediation included:

• Enforcing S3 Block Public Access
• Automated detection using AWS Config + Lambda

🧾 VM Over-Permission (Azure)

A contributor role exposed multiple VMs to a compromised service account. Remediation included:

• Creating custom RBAC roles
• Enforcing JIT Access and access reviews using Azure PIM
