☁️ Sherlocked Security – Cloud Configuration VAPT (AWS / Azure / GCP)

Harden Your Cloud Footprint Before Adversaries Exploit Misconfigurations

📄 1. Statement of Work (SOW)

Service Name: Cloud Configuration Vulnerability Assessment & Penetration Testing (VAPT)
Cloud Platforms: AWS, Azure, GCP
Client Type: SaaS, FinTech, HealthTech, Enterprises, Cloud-Native Startups
Service Model: Agentless + Credentialed API Review
Compliance Coverage: CIS Benchmarks, CSA CCM, NIST 800-53, ISO 27017, PCI-DSS, HIPAA, SOC 2

Scope Includes:

  • IAM Roles, Policies, Trust Relationships
  • S3/GCS Blob Permissions, Buckets, Storage Classes
  • Security Groups, NSGs, Firewall Rules
  • Key Management Systems (KMS, HSM)
  • Secrets Managers, Metadata APIs
  • Publicly Exposed Services (ELB, EC2, Functions, DBs)
  • Container Services (ECS, EKS, AKS, GKE)

🧠 2. Our Approach (with Visual)

🔹 Cloud-native enumeration via APIs
🔹 Attack-path modeling for privilege escalation
🔹 Misconfiguration chaining for real-world impact

  5. 🔁 One Free Retesting Cycle

  6. 🎓 Post-Remediation Cloud VAPT Certificate

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

  • ✅ Temporary IAM user/role with read-only permissions
  • ✅ Cloud inventory (Regions, Services used)
  • ✅ Specific scope (e.g., prod only, exclude dev)
  • ✅ Exclusion list (buckets, VMs, key services)
  • ✅ Admin POC for escalation alerts
  • ✅ Time window for live privilege abuse simulations

🧰 6. Tools & Technology Stack

  • 🔍 ScoutSuite, Prowler (AWS), Azucar (Azure), GCPBucketBrute
  • 🔑 Pacu (AWS Exploitation Framework), CloudSploit
  • 📜 IAM Scanner, Parliament
  • 🧪 Custom Python scripts for policy fuzzing
  • 🌐 Shodan/Censys + CloudGraph for external footprint
  • ☁️ AWS CLI, Azure CLI, GCloud CLI

🌟 8. Why Sherlocked Security? (Our USP)

Feature Sherlocked Advantage
☁️ Deep API-based Analysis No agents or invasive installs required
🔍 Multi-Cloud Support AWS, Azure, GCP – all covered in one go
🔓 Exploitation-First Approach From misconfig to PoC & abuse chain
📘 CIS Benchmark Mapping Findings aligned with compliance frameworks
🧑‍💻 Fix Support + Walkthroughs Slack/Teams support for DevOps/Cloud teams
🎓 VAPT Certificate Post-remediation cloud certification

📚 9. Real-World Case Studies

🔓 S3 Bucket Exposure via Overly Permissive IAM

Issue: IAM policy allowed s3:* on all resources
Impact: Access to confidential PII & logs
Fix: Resource-scoped permissions + KMS enforced

🧪 GCP Service Account Token Abuse

Client: SaaS on GCP
Issue: Token scoped for broader access than needed
Impact: Privilege escalation → DB Admin
Fix: Principle of Least Privilege enforced + token lifetime reduction

🛡️ 10. SOP – Standard Operating Procedure

  1. Kickoff Call & IAM Access Setup
  2. Cloud Service Inventory Mapping
  3. IAM Roles, Trust Policies & KMS Audit
  4. Storage Buckets & Secrets Manager Exposure Checks
  5. Network Layer & Security Groups Review
  6. Privilege Abuse & Role Chaining Simulations
  7. Report Generation with CIS/CVSS Ratings
  8. Fix Guidance & Retest
  9. Final Report + Certificate Delivery

📋 11. Cloud VAPT Checklist (Preview)

  1. Review IAM roles and policies for least privilege.
  2. Assess public access to S3 buckets, blobs, etc.
  3. Evaluate security group and firewall rules.
  4. Check multi-factor authentication enforcement.
  5. Test logging and monitoring configurations.
  6. Analyze cloud storage for sensitive data exposure.
  7. Review key management and secrets storage.
  8. Identify unused or deprecated services.
  9. Test serverless functions for security controls.
  10. Perform compliance checks against cloud benchmarks.
