Concept: A provider-agnostic Cloud Access Broker that delivers time-bound, least-privilege administrative access across Azure, AWS, and GCP.
Designed for environments where engineers require elevated access under controlled, auditable, and policy-driven conditions.

• Enable Just-in-Time (JIT) elevation across multiple cloud providers.
• Integrate identity governance, conditional access, and short-lived credentials.
• Maintain full audit visibility and compliance alignment (ISO 27001, SOC2, CIS).
• Remove standing admin permissions and reduce attack surface.

1. Discover — Identify privileged roles, identities, and elevation pathways across all clouds.
2. Design — Define JIT RBAC roles, durations, and approval workflows.
3. Build — Establish trust models (Azure PIM, AWS IAM + External ID, GCP WIF).
4. Integrate — Implement automation and approval logic using Entra, ITSM, or custom brokers.
5. Pilot — Validate least-privilege, time-limited access across selected accounts or projects.
6. Harden — Enforce MFA, device compliance, location restrictions, and logging.
7. Cutover — Transition from standing admin access to JIT-managed access.
8. Operate — Maintain runbooks, periodic access reviews, and SIEM correlation.
9. Evolve — Extend model to additional tenants, accounts, or environments.

• Entra ID PIM with eligible roles.
• Conditional Access enforcing MFA + compliant device.
• Role duration limited to ≤ 60 minutes.

• IAM Roles trusted to an IdP using OIDC/SAML with External ID.
• Session policies restrict actions and enforce short TTL.
• CloudTrail logging enabled for all activity.

• Workload Identity Federation (WIF) using OIDC trust.
• Role bindings use temporary impersonation tokens.
• Audit logs streamed to Cloud Logging and SIEM.

• Every elevation is linked to a ticket or change reference.
• Logs captured in Entra, Azure Activity, CloudTrail, and GCP Audit Logs.
• Access reviews scheduled quarterly per compliance framework.
• Break-glass accounts held under dual control, reviewed post-use.

• Least privilege enforced by role design and session policies.
• Conditional Access gates all privileged sessions.
• Credentials expire automatically.
• Repository contains no secrets, IPs, tenant identifiers, or customer data.
