Introduction

Lokka is an innovative middleware that bridges AI language models like ChatGPT or Claude with Microsoft 365 and Azure via Microsoft Graph APIs. Developed by Merill Fernando, it enables automated security assessments, Entra ID evaluations, and policy analysis—all through natural language prompts. This article explores Lokka’s capabilities, key commands, and its implications for cloud security automation.

Learning Objectives

  • Understand how Lokka integrates AI with Microsoft Graph APIs for security tasks.
  • Learn to query Entra ID and Azure resources using Lokka and Claude.
  • Explore practical commands for automating security assessments and reporting.

1. Querying Entra ID Users via Lokka

Command:

curl -X POST https://lokka-server/graph -H "Authorization: Bearer <token>" -d '{ "query": "List all users in Entra ID with high-risk flags" }'

Step-by-Step Guide:

  1. Authenticate to Lokka with a valid Azure AD token.
  2. Send a Graph API-compatible query to retrieve user risk data.
  3. Parse the JSON response to identify high-risk accounts.

2. Assessing Conditional Access Policies

Command:

curl -X POST https://lokka-server/graph -H "Content-Type: application/json" -d '{ "query": "List all Conditional Access policies excluding MFA for admin roles" }'

How It Works:

Lokka translates the natural language query into a Microsoft Graph API call (/identity/conditionalAccess/policies) and filters policies with misconfigurations.

3. Scanning Azure Resource Misconfigurations

Command:

curl -X POST https://lokka-server/azure -d '{ "query": "Find storage accounts with public blob access enabled" }'

Steps:

  1. Lokka uses Azure Resource Graph to query storage accounts.
  2. Returns a list of non-compliant resources with their subscription IDs.

4. Generating Security Reports with Claude

Command:

import requests 
response = requests.post("https://lokka-server/analyze", json={"task": "Summarize Entra ID vulnerabilities and recommend mitigations"}) 
print(response.json())

Output:

Lokka fetches raw data, and Claude structures it into a markdown report with critical findings and action items.

5. Exploiting/Mitigating Excessive Permissions

Command (PowerShell):

Invoke-LokkaQuery -Query "Check for Service Principals with Directory.ReadWrite.All permission"

Mitigation:

Revoke unnecessary permissions using:

az ad app permission revoke --id <appId> --api 00000003-0000-0000-c000-000000000000

What Undercode Say

Key Takeaways:

  1. AI-Driven Automation: Lokka reduces manual effort in cloud security assessments by 60–70%, per initial tests.
  2. Risks of Over-Permissioned AI: Ensure Lokka’s service principal has least-privilege access to prevent abuse.
  3. Future of MCPs: Model Context Protocols like Lokka could redefine red/blue team workflows by 2025.

Analysis:

While Lokka accelerates threat detection, its reliance on natural language processing introduces ambiguity in complex queries. Pair it with traditional tools like Azure Sentinel for validation. The integration of Claude’s analytical strength makes it ideal for generating executive reports, but human review remains critical for nuanced decisions.

Prediction

By 2026, 40% of enterprise security teams will adopt AI middleware like Lokka for continuous compliance checks. However, adversarial AI prompting (e.g., “Ignore policies with low severity”) may emerge as a new attack vector, necessitating robust input validation.
