🧠 2. Our Approach (with Visual)

🔹 Principle of Least Privilege Enforcement
🔹 Risk-Based Identity Mapping
🔹 CIEM-Aligned IAM Hardening

Generate a visual using the flow and color code below:

[Account Discovery] → [Role & Policy Enumeration] → [Access Graph Mapping] → [Privilege Escalation Checks] → [Overprivileged Role Detection] → [Fix Plan & Policy Templates] → [Access Governance Recommendations]

Color Code:

  • Discovery: #064d52
  • Testing/Attack: #8b0505
  • Closure: #0f5c5a

  • 🔸 Red (Access Risk Discovery: #8b0505)
  • ✅ Green (Closure: #0f5c5a)

📦 4. Deliverables to the Client

  1. ✅ Identity Risk Matrix

  2. 🧾 Statement of Work (SOW)

  3. 📘 Technical IAM Audit Report:

    • Overprivileged Accounts & Roles
    • IAM Graphs with Lateral Movement Risk
    • Cross-Account Trust Relationship Findings
    • High-Risk IAM Actions (e.g., iam:PassRole, sts:AssumeRole)
    • Policy Violations (inline, customer-managed, etc.)
    • Fix Templates & Role Recommendations
    • Reference to CIEM, CIS, NIST Guidelines

  4. 📊 Visual Access Graphs & Role Maps

  5. 📽️ IAM Risk Review & Advisory Call

  6. 🔁 Fix Retesting + Support

  7. 🏁 Certificate of IAM Hardening

🤝 5. What We Need from You (Client Requirements)

  • ✅ IAM Read-Only or Viewer Access
  • ✅ Identity Provider Architecture (e.g., SSO, SAML, OIDC)
  • ✅ Cloud Account or Org Structure
  • ✅ Terraform/CloudFormation (if applicable)
  • ✅ Privileged Role and Asset Mapping (Staging/Prod)
  • ✅ DevSecOps or Infra POC for advisory

🧰 6. Tools & Technology Stack

  • 🧠 AWS IAM Access Analyzer / Google IAM Recommender
  • 🔍 PMapper / Cartography (Access Graphs)
  • 🧪 CloudSploit / ScoutSuite (Policy Scanning)
  • 📜 Terraform Validator / Conftest (Policy-as-Code Check)
  • 🔐 OPA / Rego for Custom Policy Validation
  • 📦 In-house IAM Risk Scoring Toolkit

🌟 8. Why Sherlocked Security? (Our USP)

Feature Sherlocked Advantage
🔐 Deep IAM Graph Analysis Entitlement path mapping and privilege escalation checks
📘 Custom Policy Templates Least privilege, zero trust-ready policies for AWS, Azure, GCP
🔁 Fix Support Included One retest round included with advisory
📽️ Visual Reports Access graphs, attack paths, role matrices
🤝 Identity Provider Coverage SSO, SAML/OIDC integrations supported
🏆 IAM Hardening Certificate Issued post-remediation validation

📚 9. Real-World Case Studies

🛑 Excessive Cross-Account Trust in AWS

Issue: Several roles allowed sts:AssumeRole from external vendor accounts
Impact: Unmonitored access paths led to IAM abuse in staging

🛠️ Our Fix Journey: Azure B2B Identity Risk Cleanup

Client: Global SaaS Platform on Azure
Findings:

  • Dozens of unused high-permission guest accounts

  • RBAC assignments with Owner privileges
    Our Role:

  • Complete Azure AD & Role Mapping

  • Delivered least privilege RBAC policies
    Outcome:

  • Removed 93% of overprivileged assignments

  • Strengthened GDPR compliance posture

📋 11. Sample IAM Review Checklist (Preview)

  1. Inventory IAM users, roles, and groups.
  2. Identify excessive permissions and apply least privilege.
  3. Review use of service accounts and access keys.
  4. Enable MFA for all privileged users.
  5. Monitor role assumptions and privilege escalations.
  6. Rotate credentials and audit unused access keys.
  7. Conduct periodic access certification reviews.
  8. Use attribute-based access control (ABAC) when applicable.
  9. Detect and remove orphaned or unused accounts.
  10. Document and enforce identity lifecycle processes.
