Initialisation + +```python +engine = ScanEngine(subscription_id="xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx") +``` + +`ScanEngine.__init__` creates an `AzureClient` using `DefaultAzureCredential`, which automatically resolves credentials from (in order): environment variables, managed identity, Azure CLI, or VS Code login. + +### 2. Rule Loading + +```python +engine.load_rules() +``` + +`load_rules()` iterates over every `*.py` file in `scanner/rules/` that does not start with `_`. It uses Python's `importlib.util` to load each file as a module and checks that the module exposes a `scan()` function. This means: + +- **Adding a rule requires no code change to the engine** — drop a file into `scanner/rules/` and it is automatically discovered on next startup. +- Rules that fail to load (syntax errors, missing imports) are logged and skipped. The remaining rules still run. + +### 3. Scan Execution + +```python +result = engine.run_scan() +``` + +`run_scan()` iterates through all loaded rule modules, calling `module.scan(azure_client, subscription_id)` for each. Individual rule failures are caught and logged without stopping the scan. The engine collects all findings and returns a structured result dict. + +### 4. Finding Schema + +Every finding returned by a rule must conform to this schema: + +```python +{ + "rule_id": str, # e.g. "AZ-STOR-001" + "rule_name": str, + "severity": str, # HIGH | MEDIUM | LOW | INFO + "category": str, # Storage | Network | Identity | Database | Compute | KeyVault + "resource_id": str, # full Azure resource ID + "resource_name": str, + "resource_type": str, # e.g. "Microsoft.Storage/storageAccounts" + "description": str, + "remediation": str, + "playbook": str, # path to the CLI remediation script + "frameworks": dict, # {"CIS": "3.5", "NIST": "PR.AC-3", "ISO27001": "A.9.4.1"} + "detected_at": str, # ISO 8601, added by engine + "scan_id": str, # UUID, added by engine +} +``` + +--- + +## How Findings Flow to the API + +``` +run_scan() + → findings[] in memory + → db.save_scan(result) # persists to PostgreSQL + → return scan result JSON + +GET /api/findings + → db.get_findings(filters) # reads from PostgreSQL + → returns JSON array + +GET /api/score + → db.get_score() # severity-weighted 0-100 + → returns {"score": 82} + +GET /api/compliance/cis + → db.get_compliance_score("cis") # joins DB findings with CIS JSON + → returns per-control pass/fail breakdown +``` + +--- + +## How Rules Are Loaded Dynamically + +The engine uses Python's `importlib` to load rule files at runtime. No registry or central list is needed: + +```python +for rule_path in sorted(RULES_DIR.glob("*.py")): + if rule_path.name.startswith("_"): + continue + spec = importlib.util.spec_from_file_location(rule_path.stem, rule_path) + module = importlib.util.module_from_spec(spec) + spec.loader.exec_module(module) + if callable(getattr(module, "scan", None)): + self.rules.append(module) +``` + +Each rule module is a plain Python file — no base class, no registration decorator. The only contract is the `scan(azure_client, subscription_id)` function signature. + +--- + +## How Sentinel Integration Works + +> **Note:** Sentinel push is handled by a separate team. This section documents the integration point. + +After `run_scan()` returns, findings can be forwarded to Microsoft Sentinel via the Azure Monitor Ingestion API.

Attackers don't even need to "hack" anything. Automated tools scan Azure for public blobs constantly. If yours is exposed it will be found, usually within hours. + +**AZ-STOR-002 — Storage account allows unencrypted HTTP** +Any data moving over plain HTTP can be read by anyone on the same network path. This sounds theoretical until you realise most corporate VPNs, shared offices and cloud interconnects are exactly that kind of shared environment. One internal tool uploading customer data over HTTP to Azure storage is all it takes. The fix is one toggle — HTTPS only — but it gets missed constantly. + +**AZ-NET-001 — NSG allows SSH from internet** + +SSH brute force attacks are constant — attackers run automated scripts trying millions of username and password combinations against any open port 22 they find. In 2023 a university research cluster was compromised through an exposed SSH port, with attackers using it to mine cryptocurrency for three months before detection. Restricting SSH to known IP ranges or using Azure Bastion eliminates this risk entirely. + + +**AZ-NET-002 — NSG allows RDP from internet** + +RDP on port 3389 open to 0.0.0.0/0 is one of the most scanned ports on the internet — automated bots find it within minutes of a VM being provisioned. The 2021 Colonial Pipeline attack started with an exposed RDP port and a compromised password. Once an attacker gets in via RDP they have full GUI access to the machine and can move laterally across the entire network. + + +**AZ-IDN-001 — Overprivileged service principal** +Contributor at subscription scope means the service principal can touch everything — every VM, every database, every storage account across the whole subscription. The moment that client secret leaks — through a git commit, a build log, a misconfigured app — the attacker has the keys to the kingdom. This exact pattern showed up in the SolarWinds breach. Least privilege is not optional. + +**AZ-IDN-002 — MFA not enforced on privileged accounts** +Credential stuffing is not sophisticated. Attackers just take leaked password lists from other breaches and try them on Azure AD. Without MFA a matching password is all they need. Microsoft says MFA stops 99.9% of these attacks. A Global Admin account without MFA is genuinely one of the highest risk findings you can have — one leaked password from any other service and your entire tenant is gone. + +**AZ-DB-001 — SQL Server TDE disabled** +The database itself might be behind a firewall, but what about the backups? Backup files get moved around — to blob storage, to tapes, to DR sites. Without TDE the data is sitting in plain text in all of those places. A healthcare company learned this the hard way in 2019 when stolen backup files exposed 2.3 million patient records. The attacker never touched the live database. + +**AZ-DB-002 — SQL Server firewall allows all IPs** +Opening the SQL Server firewall to all IPs is the same as putting your database on the public internet. Shodan and similar tools index these constantly. In 2020 a startup had their production database dumped within days of launching because the firewall rule was still set to 0.0.0.0 from a development config that nobody cleaned up. Lock it to your app service IPs only — nothing else needs direct database access. + +**AZ-CMP-001 — Unencrypted managed disk** +An attacker who gets into your subscription — even temporarily — can snapshot a disk in seconds. They create the snapshot, export it, mount it on their own VM and read everything on it at their leisure. The original VM keeps running, no one notices. A SaaS company found out about this 6 weeks after it happened when their data showed up for sale. The disks were unencrypted so the snapshot was immediately readable. + +**AZ-KV-001 — Key Vault soft delete disabled** +Key Vault is where everything important lives — database passwords, API keys, TLS certificates, encryption keys. Without soft delete an attacker or a disgruntled employee can delete every single secret permanently in about 30 seconds. No recovery, no rollback. A real incident in 2021 saw an employee delete an entire production Key Vault on their last day. The company was down for 6 days rebuilding access from scratch. Soft delete costs nothing to enable.

Linters add style and convention rules that differ across contributors and would generate noise on code written before the linter was introduced. A syntax check has a binary, objective outcome. That is the right scope for a CI gate on an open source project where contributors are writing their first rules. + +### Why `importlib` and not regex for structure validation + +Regex on Python source is fragile. A field could be assigned via a helper function, computed from a base class, or split across continuation lines. `importlib.util.spec_from_file_location` actually executes the module and then `hasattr()` checks the resulting object — the only way to be certain the attribute is present and accessible at runtime. This is the same mechanism the scanner engine uses when loading rules, so the CI check mirrors what production does. + +### Why `bash -n` and not just checking file existence + +An earlier version of this check only verified that a playbook file existed. A `.sh` file with a bash syntax error — an unclosed `if`, a bad heredoc, a missing `fi` — will crash immediately when an operator runs it in response to a real finding. `bash -n` parses without executing, so it catches structural errors at zero risk of touching any Azure resource. Existence alone is not sufficient. + +### Why the credential scan uses grep exclusions rather than an allowlist + +The patterns being scanned (`password=`, `secret=`, `api_key=`) appear legitimately in two contexts: environment variable lookups (`os.environ`, `os.getenv`) and inline comments. Both are explicitly excluded. The scan is scoped to literal assignment — the pattern that indicates a value is hardcoded in source. A grep-based approach is auditable: every exclusion is visible in one place and any contributor can read exactly what is and is not excluded. + +### Why the credential scan excludes `venv/` + +On GitHub Actions the checkout is clean with no `venv/`. Locally, `venv/` contains thousands of lines from third-party packages that match patterns like `password=None` as function arguments. Excluding `venv/` prevents false positives when contributors run the check locally without creating a confusing discrepancy between local and CI results. + +### Why the cross-reference check walks compliance JSONs rather than rule files + +The check is designed to catch a deletion scenario: a rule file is removed but its entry in one or more compliance JSONs is not. Walking the JSONs and looking up each referenced rule ID against the set of existing rule files catches stale references. The inverse check — verifying every rule file has a compliance entry — is not enforced because a rule may legitimately not map to every framework. + +--- + +## Edge cases handled + +**Rule file has syntax error but passes `py_compile`** +Not possible. `py_compile` detects all syntax errors that prevent the AST from parsing. If `py_compile` passes, the file can be imported. + +**Rule file imports a package not in `requirements.txt`** +Check 2 will fail with `import error` when `spec.loader.exec_module` raises `ModuleNotFoundError`. The error message names the missing package. Add it to `requirements.txt`. + +**Two rule files define the same `RULE_ID`** +Check 2 collects all IDs with `defaultdict(list)` before reporting, so it catches every duplicate in a single run rather than stopping at the first. The failure message names both files. + +**A playbook file exists but contains only a shebang and no logic** +`bash -n` passes — a script with only `#!/bin/bash` is syntactically valid. This is intentional: a stub playbook during development is acceptable; a broken playbook is not. + +**A compliance JSON has a `controls` key with no entries** +Check 5 reports the number of controls but does not fail on zero. An empty `controls` block is structurally valid JSON. Check 7 will simply find nothing to cross-reference. If you want to enforce minimum control counts, add a `len(controls) == 0` check to Check 5. + +**The `api/` directory does not exist** +Check 6 prints `No api/ directory found — skipping` and exits 0. The check is designed to be safe to include before the API module is added. + +**A framework JSON file references a rule ID that was renamed** +Check 7 catches this. The referenced ID will not be in `existing_ids` (which is built from the current `RULE_ID` attribute of each rule file) and CI fails with the exact JSON file and rule ID that is stale. + +**Trailing comma in a compliance JSON** +Check 5 catches this. Python's `json.load` raises `json.JSONDecodeError` on trailing commas, and the failure message includes the line number from the decoder. + +**Local `venv/` directory triggers credential scan false positives** +The scan excludes `--exclude-dir=venv`. On GitHub Actions there is no `venv/` to exclude, so the flag is harmless there. + +--- + +## How the CI summary works + +The final step uses `if: always()` so it runs regardless of whether earlier steps passed or failed. Each check step has a unique `id`. The summary step reads the outcome of every step via environment variables: + +```yaml +- name: CI Summary + if: always() + env: + SYNTAX: ${{ steps.syntax_check.outcome }} + STRUCTURE: ${{ steps.structure_check.outcome }} + ... +``` + +GitHub Actions sets `outcome` to `success`, `failure`, `skipped`, or `cancelled`. The summary step writes a markdown table to `$GITHUB_STEP_SUMMARY`, which GitHub renders as a panel on the Actions run page. This means a reviewer can see which check failed without opening any log. + +When running locally (no `$GITHUB_STEP_SUMMARY` environment variable), the summary is printed to stdout only. + +--- + +## Fixing common failures + +| Failure message | Cause | Fix | +|---|---|---| +| `SYNTAX ERROR: scanner/rules/az_xxx_000.py` | Invalid Python syntax | Open the file, find the syntax error, fix it | +| `missing field 'RULE_ID'` | Rule file does not define `RULE_ID` at module level | Add `RULE_ID = "AZ-XXX-000"` at the top of the file | +| `SEVERITY 'MEDIUM-HIGH' not in {...}` | SEVERITY value is not one of the five allowed strings | Change to `CRITICAL`, `HIGH`, `MEDIUM`, `LOW`, or `INFO` | +| `DUPLICATE RULE_ID 'AZ-NET-003'` | Two rule files declare the same ID | Assign a unique ID to the newer file | +| `POTENTIAL CREDENTIAL LEAK` | A literal secret is present in source | Replace with `os.environ["VAR_NAME"]` | +| `MISSING PLAYBOOK: playbooks/cli/fix_az_xxx_000.sh` | No playbook created for the new rule | Create `playbooks/cli/fix_az_xxx_000.sh` | +| `BASH SYNTAX ERROR: playbooks/cli/fix_az_xxx_000.sh` | Shell script has invalid syntax | Run `bash -n playbooks/cli/fix_az_xxx_000.sh` locally to see the error | +| `invalid JSON — ...` | Trailing comma or other JSON error in a framework file | Open the file, find the bad line (error message includes line number), fix it | +| `references 'AZ-XXX-000' but no matching rule file found` | A compliance JSON references a rule that does not exist | Either create the rule file or remove the entry from the compliance JSON | diff --git a/requirements.txt b/requirements.txt index ee81347..74c911f 100644 --- a/requirements.txt +++ b/requirements.txt @@ -14,3 +14,4 @@ psycopg2-binary==2.9.9 python-dotenv==1.0.0 pyjwt==2.8.0 requests==2.31.0 +pyyaml==6.0.1 diff --git a/scanner/rules/az_net_003.py b/scanner/rules/az_net_003.py index 54d2ca1..a0a18e0 100644 --- a/scanner/rules/az_net_003.py +++ b/scanner/rules/az_net_003.py @@ -9,7 +9,6 @@ CATEGORY = "Network" FRAMEWORKS = {"CIS": "9.3", "NIST": "SC-7", "ISO27001": "A.13.1.1"} DESCRIPTION = ( - DESCRIPTION = ( "A Network Security Group has an inbound rule allowing unrestricted access " "on port 443 from any source (0.0.0.0/0).

Overview + +This test plan covers the verification of the OpenShield API deployment +to the Render free tier. The goal is to confirm: + +- The Render Web Service builds and deploys the Flask app successfully. +- The database is automatically initialized on startup via `init_db`. +- The pre-commit hook and GitHub Actions CI pipeline gate the code properly. +- The CI pipeline is **community-friendly**, allowing forks to pass even without custom secrets. +- Real Azure scan tests are gated behind `RUN_REAL_SCAN=true` so contributor CI never depends on live Azure credentials. +- All 23 API edge cases (routing, filtering, authentication) function correctly in the live cloud environment. + +--- + +## 2. Methodology and Test Rationale + +To ensure the highest reliability of the deployment while accommodating free-tier constraints and community contributions, specific methods and test strategies were chosen: + +### 2.1 Infrastructure and Pipeline Strategy +* **Targeting Render over Azure F1:** Azure App Service's F1 tier imposes a strict 60 CPU-minute daily cap. Render provides unmetered CPU on the free tier, making it significantly more reliable for demo and development environments. +* **Database Initialization:** The `api/models/finding.py` was updated with an `init_db` method. This method ensures that all required tables (`scans`, `findings`) are created automatically during the first deployment, preventing HTTP 500 errors. +* **Pre-commit Hook:** Fails fast. By running syntax checks and local API smoke tests *before* the commit is allowed, we prevent broken code from polluting the remote branch. +* **Community-Friendly CI Gate:** The GitHub Action is designed to be zero-friction for contributors. + * **Optional Smoke Tests:** If `JWT_SECRET` is not set (typical for forks), the smoke test step is gracefully skipped rather than failing the build. + * **Configurable URL:** The `API_URL` is configurable via GitHub Secrets/Variables, defaulting to the main production instance if not provided. + * **Conditional Real Scan Tests:** TC-13 and TC-14 (real Azure scan execution) only run when `RUN_REAL_SCAN=true` and all four Azure credentials are present. This separates API smoke testing from live scan regression testing. Contributor and fork CI always passes safely — real scan validation is reserved for maintainer-controlled deployment pipelines (`dev` and `main` branches). + +### 2.2 Token Generation Method +* **Dynamic HS256 Signing:** Instead of using a hardcoded dummy string, the test script dynamically generates a real token signed with the environment's `JWT_SECRET`. +* **Default Secret Alignment:** The smoke test defaults to `change-me-in-production`, matching the API's default. This allows tests to run "out of the box" in local environments without extra configuration. + +> [!CAUTION] +> **ABSOLUTE SECURITY REQUIREMENT:** For any production deployment (Render, Azure, etc.), you **MUST** override the default `JWT_SECRET` with a long, random, and unique string. Leaving the default value in place makes your API vulnerable to unauthorized access via token forging. + +### 2.3 API Smoke Test Strategy (The 23 Cases) +The 23 test cases were selected to prove the API is structurally sound and resilient: +* **Health Check (TC-01 to TC-03):** Confirms base app connectivity and ensures public routes are not locked. +* **Core Endpoints (TC-04 to TC-17):** Verifies the actual business logic and JSON structure. +* **Auth/Security (TC-18 to TC-19):** Confirms the JWT middleware is strictly enforced. +* **Edge Cases and Resilience (TC-20 to TC-23):** Ensures the app does not crash when given bad input or non-existent routes. + +#### Conditional vs Always-Run Tests + +| Mode | TC-13 / TC-14 | All others | +|---|---|---| +| Contributor / fork (no `RUN_REAL_SCAN`) | `SKIP` — printed with reason, not a failure | Always run | +| Maintainer deployment (`RUN_REAL_SCAN=true` + Azure credentials) | Run real scan against live subscription | Always run | + +Run modes: +```bash +# Contributor / local (no Azure credentials needed) +API_URL=https://openshield-api.onrender.com JWT_SECRET= python tests/smoke_test.py + +# Maintainer — full real scan +API_URL=https://openshield-api.onrender.com JWT_SECRET= \ + RUN_REAL_SCAN=true \ + AZURE_SUBSCRIPTION_ID= \ + AZURE_CLIENT_ID= \ + AZURE_CLIENT_SECRET= \ + AZURE_TENANT_ID= \ + python tests/smoke_test.py +``` + +--- + +## 3.

What is OpenShield?

+

+ OpenShield is an open-source Azure CSPM platform designed to identify cloud misconfigurations, + map findings to compliance frameworks, monitor posture drift, and provide remediation guidance. It helps users understand + what is insecure, why it matters, and how to fix it. +

+
+
+

Misconfiguration Scanning

+

Checks Azure resources for risky settings that can expose data, weaken access control, or reduce security visibility.

+
+
+

Compliance Mapping

+

Connects security findings to frameworks such as CIS, NIST, and ISO so issues can be understood in a governance context.

+
+
+

Remediation Guidance

+

Provides practical fix guidance using Azure CLI, ARM templates, Terraform, and validation checks where applicable.

+
+
+

Drift Detection

+

Tracks changes in cloud security posture so teams can identify when previously safe configurations become risky.

+
+
+
+ +
+

How OpenShield Works

+

+ OpenShield follows a simple scanning pipeline: collect Azure resource configuration, evaluate rules, + generate findings, map them to controls, and expose results through the platform. +

Core Components

+

+ OpenShield is built with a simple MVP-friendly architecture: Python scanner, Flask API, + PostgreSQL storage, React frontend, compliance mapping, Sentinel integration, and supporting remediation playbooks. +

+
+
+

Scanner Engine

+

Python-based scanner that uses Azure SDK clients to inspect Azure resource configuration and evaluate security rules.

+ PythonAzure SDK +
+
+

Flask API

+

Backend API layer responsible for exposing scan results, findings, metadata, and platform data to the frontend.

+ FlaskREST API +
+
+

PostgreSQL

+

Stores scan findings, rule metadata, compliance mappings, and remediation-related information.

+ DatabasePersistence +
+
+

React Dashboard

+

Frontend dashboard for viewing findings, severity, affected resources, and security posture information.

+ ReactDashboard +
+
+

Playbooks

+

Remediation documents that explain how to fix detected issues using CLI, ARM templates, Terraform, and validation steps.

+ Azure CLIARMTerraform +
+
+

Sentinel

+

Supports security monitoring and SIEM-focused documentation where OpenShield findings connect with detection workflows.

+ SIEMDetection +
+
+
+ +
+

CSPM Basics

+

+ Cloud Security Posture Management focuses on continuously identifying insecure cloud configurations. + In Azure, common examples include public storage exposure, weak network rules, missing logging, + overly permissive identities, and disabled security protections. +

+
+
+

Why It Matters

+

Cloud breaches often happen because resources are misconfigured, not because the cloud provider itself failed.

+
+
+

Example Issues

+
    +
  • Public blob access
    • +
  • Weak network security groups
    • +
  • Missing monitoring or logging
    • +
  • Over-permissive access policies
    • +
+
+
+

OpenShield Role

+

OpenShield helps surface these issues, explain their impact, and guide users toward safer Azure configurations.

+
+
+
+ +
+

Compliance Mapping

+

+ A single security finding can map to multiple compliance controls. OpenShield uses mappings to connect + technical misconfigurations with security frameworks such as CIS Benchmarks, NIST CSF, ISO 27001, and SOC 2. +

+
+

CIS

Maps findings to cloud security benchmarks and configuration recommendations.

+

NIST

Connects findings to broader cybersecurity controls and risk management practices.

+

ISO 27001

Supports governance, information security controls, and audit-oriented reporting context.

+

SOC 2

Connects relevant findings to trust-service control areas such as security, availability, and confidentiality.

+
+
+ +
+

Remediation Philosophy

+

+ Detection alone is not enough. A useful CSPM tool should explain the risk, provide fix guidance, + and help validate whether the issue has actually been resolved. +

+
+

Detect

Identify insecure Azure configuration accurately with minimal false positives.

+

Explain

Show why the finding matters, what resource is affected, and what the risk is.

+

Fix

Provide Azure CLI, ARM template, or Terraform-based remediation steps that users can apply safely.

+

Validate

Re-run checks or confirm settings to verify the misconfiguration is resolved.

+
+
+ +
+

Contributor Learning Path

+

+ New contributors should understand the security problem first, then the OpenShield architecture, + then the rule and remediation workflow. +

+
+
+

Suggested Path

+
    +
  1. Understand CSPM fundamentals
    2. +
  2. Review the OpenShield architecture
    3. +
  3. Explore existing documentation and rules
    4. +
  4. Understand findings, mappings, and remediation playbooks
    5. +
  5. Add or improve rules and playbooks
    6. +
  6. Test changes against Azure safely
    7. +
+
+
+

Contribution Focus

+

Good contributions improve detection accuracy, remediation quality, documentation clarity, or platform reliability.

Legacy rows missing CVE fields are enriched on-demand only once. +2. Dashboard-Ready Summary Endpoint: The /api/score/cve-summary endpoint allows the frontend to fetch high-level statistics (Total Findings, Exploit Count, Max CVSS) in one call instead of processing thousands of records locally. +3. Actionable Risk (CISA KEV): The exploit_available flag uses the CISA Known Exploited Vulnerabilities catalogue, allowing the dashboard to highlight high-priority risks that are being exploited in the wild. +4. Persistent Historical State: Enrichment happens at the time of scan, meaning the dashboard shows the CVE status as it existed on that day. This ensures accurate compliance and historical reporting. + +## Security and Compliance Audit + +1. No Hardcoded Secrets: All credentials (DATABASE_URL, JWT_SECRET) are handled via environment variables. +2. SSRF Protection: NVD query parameters are sanitized and derived from internal static maps. +3. SQL Safety: All database additions use parameterized queries to prevent injection. +4.

Pages (7): - Monitoring — security score gauge, trend chart, findings distribution, issues by resource group, category scores - Discovery — resource table with issue counts, risk filters, category grouping, resource group filtering, clickable category cards - Prioritization — risk vs effort matrix, ranked list with quick remediation preview, all 25 action items; click-to-select syncs matrix + action items + remediation panel - Detailed Scan — findings list with playbook tabs (portal/CLI/validation), navigates from Prioritization with context banner - Compliance — CIS/NIST/ISO27001/SOC2 framework cards, controls table, comparison trend chart, CSV/JSON export - Drift — configuration change timeline, ADDED/REMOVED/MODIFIED events with before/after values, who changed it and when - AI Assistant — 3-column layout (findings picker, chat, suggestions + CVE analysis + executive summary); AI chat wired to aiApi.js with smart mock responses; finding context passed from Scan page API service layer (src/utils/api.js): - Demo/Live mode toggle persisted in localStorage - JWT token bootstrap in App.jsx - Health check on startup with auto-fallback to demo mode - Real fetch calls with mock fallback for every endpoint: /api/score, /api/findings, /api/findings/:id, /api/findings/:id/playbook, /api/resources, /api/prioritization, /api/drift, /api/scans, /api/scans/trigger, /api/scans/:id, /api/compliance/cis|nist|iso27001 - snake_case → camelCase normalisation for all backend responses - Separate aiApi.js for AI endpoints with smart mock responses Header features: - Run Scan button with live polling (4s interval, 5-min timeout, elapsed timer) - Demo/Live badge with connection test before switching - Error popup if backend is unreachable Design system: - Tailwind CSS v3 with custom tokens (brand, severity, bg-dark, status) - Dark mode via class strategy, persisted in localStorage - Fully responsive — mobile hamburger drawer, stacked layouts on sm - Dot-pattern background, soft shadows, consistent 4px grid Mock data: - 8 api.*.json files matching exact backend response schema - API_ENDPOINTS.txt — backend contract document with implementation status, database schema, seed data, and endpoint ordering guide Co-Authored-By: Claude Sonnet 4.6 * feat(frontend): wire live backend, fix JWT auth, add Vercel deployment config - Fix JWT: read VITE_JWT_TOKEN env var so live API calls authenticate correctly (was sending plain string 'dev-demo-token' which backend rejected as invalid JWT) - Add vercel.json with SPA rewrites so /monitoring, /scan etc don't 404 - Monitoring page now fetches real score + findings in live mode and computes stats/distribution/resource-group breakdown from actual backend data - Run Scan button shows subscription ID input in live mode (optional — backend falls back to AZURE_SUBSCRIPTION_ID env var if blank) - api.js: no silent localhost fallback in production builds (fails loudly if VITE_API_URL is not set) ---------

What is OpenShield?

-

- OpenShield is an open-source Azure CSPM platform designed to identify cloud misconfigurations, - map findings to compliance frameworks, monitor posture drift, and provide remediation guidance. It helps users understand - what is insecure, why it matters, and how to fix it. -

-
-
-

Misconfiguration Scanning

-

Checks Azure resources for risky settings that can expose data, weaken access control, or reduce security visibility.

-
-
-

Compliance Mapping

-

Connects security findings to frameworks such as CIS, NIST, and ISO so issues can be understood in a governance context.

+
+ +
+ +
+
+
+
Open-source Azure CSPM platform
+

Learn Azure security posture with OpenShield.

+

+ OpenShield scans Azure subscriptions for misconfigurations, enriches findings with CVE intelligence, + maps risks to compliance frameworks, stores scan history, exposes a Flask API, and presents results through + a React dashboard with demo and live modes. +

Overview

+

What OpenShield does

+

+ OpenShield is built to help users identify risky Azure configurations, understand the impact, connect findings + to compliance controls, and follow practical remediation guidance. It is not a cloud provider replacement or a SIEM; + it is a focused Azure CSPM platform for posture visibility and learning. +

+ +
+
+

Misconfiguration scanning

+

Dynamic Python rule modules inspect Azure resources through Azure SDK clients and return normalized security findings.

+
ScannerAzure SDKRules
+
+
+

CVE enrichment

+

Findings can be enriched with NVD/CVE context so security issues are easier to prioritize and explain.

+

+
+
+

Compliance mapping

+

Technical findings are mapped to CIS Azure, NIST CSF, ISO 27001, and SOC 2 for governance-oriented reporting.

+
+
+

Remediation guidance

+

Each rule is paired with a CLI playbook so contributors and users can move from detection to manual remediation.

How OpenShield Works

+
+

Architecture

+

Production-shaped, MVP-friendly architecture

- OpenShield follows a simple scanning pipeline: collect Azure resource configuration, evaluate rules, - generate findings, map them to controls, and expose results through the platform. + The platform follows a simple pipeline: Azure credentials are resolved by DefaultAzureCredential, the scan engine loads + rule files from scanner/rules/*.py, findings are enriched and stored, then exposed through the API and dashboard.

CSPM Basics

+
+

Learning roadmap

+

Recommended learning path

- Cloud Security Posture Management focuses on continuously identifying insecure cloud configurations. - In Azure, common examples include public storage exposure, weak network rules, missing logging, - overly permissive identities, and disabled security protections. + Follow this path if you are new to OpenShield or preparing to contribute. Learn the security problem before touching code.

-
-
-

Why It Matters

-

Cloud breaches often happen because resources are misconfigured, not because the cloud provider itself failed.

-
-
-

Example Issues

-
    -
  • Public blob access
    • -
  • Weak network security groups
    • -
  • Missing monitoring or logging
    • -
  • Over-permissive access policies
    • -
-
-
-

OpenShield Role

-

OpenShield helps surface these issues, explain their impact, and guide users toward safer Azure configurations.

Compliance Mapping

-

- A single security finding can map to multiple compliance controls. OpenShield uses mappings to connect - technical misconfigurations with security frameworks such as CIS Benchmarks, NIST CSF, ISO 27001, and SOC 2. -

-
-

CIS

Maps findings to cloud security benchmarks and configuration recommendations.

-

NIST

Connects findings to broader cybersecurity controls and risk management practices.

-

ISO 27001

Supports governance, information security controls, and audit-oriented reporting context.

-

SOC 2

Connects relevant findings to trust-service control areas such as security, availability, and confidentiality.

+ -
-

Remediation Philosophy

+
+

Contributors

+

Where contributors can help

- Detection alone is not enough. A useful CSPM tool should explain the risk, provide fix guidance, - and help validate whether the issue has actually been resolved. + Good contributions should improve detection accuracy, correctness of findings, remediation quality, documentation clarity, + or system reliability. Cosmetic work is useful only when it supports those goals.

+
-

Detect

Identify insecure Azure configuration accurately with minimal false positives.

-

Explain

Show why the finding matters, what resource is affected, and what the risk is.

-

Fix

Provide Azure CLI, ARM template, or Terraform-based remediation steps that users can apply safely.

-

Validate

Re-run checks or confirm settings to verify the misconfiguration is resolved.

+

Rules

Add or improve Azure checks with accurate metadata, safe SDK usage, realistic test cases, and clear findings.

+

Playbooks

Keep remediation scripts aligned with rules. Every fix should include validation and avoid unsafe blanket changes.

+

Compliance

Improve CIS, NIST, ISO 27001, and SOC 2 mappings. Do not map controls just to inflate coverage.

+

Frontend

Connect live API flows carefully. Do not leave mock-backed UI pretending to be production data.

+

Backend

Implement missing endpoints consistently with JWT auth, error handling, data contracts, and PostgreSQL models.

+

AI and Sentinel

Improve RAG quality, knowledge loading, KQL rules, and ingestion without exposing sensitive findings unnecessarily.

-
-

Contributor Learning Path

+
+

Known gaps

+

Current cleanup items

- New contributors should understand the security problem first, then the OpenShield architecture, - then the rule and remediation workflow. + These are not failures; they are useful follow-up targets. Documenting them prevents contributors from pretending the platform is more complete than it is.

-
-
-

Suggested Path

-
    -
  1. Understand CSPM fundamentals
    2. -
  2. Review the OpenShield architecture
    3. -
  3. Explore existing documentation and rules
    4. -
  4. Understand findings, mappings, and remediation playbooks
    5. -
  5. Add or improve rules and playbooks
    6. -
  6. Test changes against Azure safely
    7. -
-
-
-

Contribution Focus

-

Good contributions improve detection accuracy, remediation quality, documentation clarity, or platform reliability.

-
+ +
+
+

Documentation drift

+
    +
  • Some README/docs references still mention 20 rules while the repo has 39.
    • +
  • Some startup commands assume python, but local environments may only expose python3.
    • +
  • API docs and implementation should stay aligned, especially score response shape.
    • +
+
+
+

Implementation gaps

+
    +
  • Some frontend live pages depend on endpoints that may still be mock-backed.
    • +
  • Examples include resources, drift, prioritization, and finding-specific playbook routes.
    • +
  • Fix syntax issues before claiming AI pipeline readiness.

The rule includes logging, fetching applications from Graph API, and evaluating credentials. * Add AZ-IDN-007 rule for MFA registration detection This rule detects active user accounts in Entra ID that do not have multi-factor authentication methods registered, highlighting potential security vulnerabilities. * Add AZ-IDN-008 rule for RBAC role scanning This script detects custom RBAC roles with wildcard or overly broad permissions at the subscription scope and provides remediation steps. * Add AZ-IDN-009 rule for role assignment alerts This rule checks for the absence of activity log alerts for role assignment changes in Azure subscriptions, logging findings if no alerts are configured. * Add remediation playbook for AZ-IDN-005 This script provides a remediation playbook for removing high privilege roles from guest users in Entra ID, including usage instructions and role assignment fetching. * Add remediation playbook for AZ-IDN-006 This script provides a remediation playbook for rotating service principal client secrets older than 90 days. It includes usage instructions and steps for listing, resetting credentials, and migrating to managed identities. * Add MFA enforcement remediation playbook script This script provides a remediation playbook for enforcing MFA registration for users without MFA in Entra ID. It includes steps to identify users and create a Conditional Access policy. * Add remediation playbook for AZ-IDN-008 This script provides a playbook for remediating custom RBAC roles with wildcard permissions at the subscription scope, guiding users through listing, reviewing, and updating roles. * Add script to create activity log alert for role changes This script creates an activity log alert for role assignment changes to detect privilege escalation in real time. * Add new controls for Azure security compliance * Add new NIST CSF controls for identity and access management * Add ISO 27001 controls for security compliance Added new controls for privileged access management, password management, secure log-on procedures, and event logging to comply with ISO 27001 standards. * Add SOC 2 controls for logical access and monitoring --- .../frameworks/cis_azure_benchmark.json | 25 ++++ compliance/frameworks/iso27001.json | 25 ++++ compliance/frameworks/nist_csf.json | 25 ++++ compliance/frameworks/soc2.json | 25 ++++ playbooks/cli/fix_az_idn_005.sh | 58 ++++++++ playbooks/cli/fix_az_idn_006.sh | 59 ++++++++ playbooks/cli/fix_az_idn_007.sh | 56 +++++++ playbooks/cli/fix_az_idn_008.sh | 74 +++++++++ playbooks/cli/fix_az_idn_009.sh | 65 ++++++++ scanner/rules/az_idn_005.py | 132 +++++++++++++++++ scanner/rules/az_idn_006.py | 140 ++++++++++++++++++ scanner/rules/az_idn_007.py | 97 ++++++++++++ scanner/rules/az_idn_008.py | 91 ++++++++++++ scanner/rules/az_idn_009.py | 91 ++++++++++++ 14 files changed, 963 insertions(+) create mode 100644 playbooks/cli/fix_az_idn_005.sh create mode 100644 playbooks/cli/fix_az_idn_006.sh create mode 100644 playbooks/cli/fix_az_idn_007.sh create mode 100644 playbooks/cli/fix_az_idn_008.sh create mode 100644 playbooks/cli/fix_az_idn_009.sh create mode 100644 scanner/rules/az_idn_005.py create mode 100644 scanner/rules/az_idn_006.py create mode 100644 scanner/rules/az_idn_007.py create mode 100644 scanner/rules/az_idn_008.py create mode 100644 scanner/rules/az_idn_009.py diff --git a/compliance/frameworks/cis_azure_benchmark.json b/compliance/frameworks/cis_azure_benchmark.json index 91661e8..ef60b90 100644 --- a/compliance/frameworks/cis_azure_benchmark.json +++ b/compliance/frameworks/cis_azure_benchmark.json @@ -77,6 +77,31 @@ "control_id": "1.15", "control_name": "Ensure that 'Guest invite restrictions' is set to 'Only users assigned to specific admin roles can invite guest users'", "description": "Unrestricted guest user invitation settings allow any member of the organisation to invite external users into the tenant without administrative review.
