Security Principles

1. Defense in Depth

Multi-Layer Security Strategy:

Defense in Depth Security Layers

Each layer provides independent protection, ensuring that if one layer is compromised, others continue to provide security.


2. Least Privilege

Principle: Every user, service, and component receives only the minimum permissions necessary to perform its function.

Implementation:

Users:
  - Default role: Guest (view public content only)
  - Escalation: Request-based role assignment
  - Review: Quarterly access reviews

Services:
  - Service accounts: Minimal Kubernetes RBAC
  - Database users: Scoped to specific tables
  - API keys: Limited scope and expiration

Infrastructure:
  - Pod security: Non-root users
  - Network policies: Whitelist approach
  - Storage access: Time-limited SAS tokens

3. Zero Trust

Principle: Never trust, always verify. No implicit trust based on network location.

Implementation:

Zero Trust Security Flow

Features:

  • No automatic trust for internal networks
  • Every request authenticated and authorized
  • Context-aware access decisions
  • Continuous monitoring and re-evaluation

4. Security by Design

Principle: Security considerations integrated from the earliest design phase.

Development Lifecycle:

Requirements → Design → Implementation → Testing → Deployment
     ↓            ↓           ↓            ↓           ↓
  Threat      Security    Secure       Security    Security
  Modeling    Review      Coding       Testing     Hardening

Practices:

  • Threat modeling during design
  • Security code reviews
  • Static code analysis
  • Dynamic security testing
  • Penetration testing

Security Layers

Layer 1: Network Security

External Network Protection

TLS/SSL Encryption:

Configuration:
  Minimum Version: TLS 1.2
  Preferred Version: TLS 1.3
  Cipher Suites: Strong only (AES-256, ChaCha20)
  Certificate Provider: Let's Encrypt
  Certificate Management: Automated (cert-manager)
  Rotation: Automatic before expiration

Protocol Support: ✅ TLS 1.3 (preferred)
  ✅ TLS 1.2 (minimum)
  ❌ TLS 1.1 (disabled)
  ❌ TLS 1.0 (disabled)
  ❌ SSL 3.0 (disabled)
  ❌ SSL 2.0 (disabled)

Certificate Management:

cert-manager Controller
       ↓
   Monitors Certificate Resources
       ↓
   Requests from Let's Encrypt
       ↓
   Validates Domain (HTTP-01)
       ↓
   Stores in Kubernetes Secrets
       ↓
   NGINX Ingress Reads Secrets

kind: NetworkPolicy
metadata:
  name: api-network-policy
  namespace: kinana-dev
spec:
  podSelector:
    matchLabels:
      app: api

Layer 2: Application Security

Authentication System

OAuth 2.0 / OpenID Connect Implementation:

OAuth 2.0 Authentication Flow

The OAuth 2.0 / OpenID Connect flow handles user authentication and token generation.

JWT Token Structure:

{
  "header": {
    "alg": "RS256",
    "typ": "JWT",
    "kid": "key-id-2024"
  },
  "payload": {
    "iss": "https://id.kinana.ai",
    "sub": "user-uuid-12345",
    "aud": ["kinana-api", "kinana-app"],
    "exp": 1700000000,
    "iat": 1699996400,
    "nbf": 1699996400,
    "jti": "token-uuid",
    "roles": ["student", "user"],
    "permissions": ["files:read", "files:write", "courses:read"],
    "tenant_id": "tenant_001",
    "email": "user@example.com",
    "email_verified": true,
    "name": "John Doe"
  },
  "signature": "..."
}

Token Lifecycle Management:

Access Token:
  Lifetime: 1 hour
  Purpose: API authentication
  Storage: Memory only (never localStorage)
  Revocation: Blacklist in Redis

Refresh Token:
  Lifetime: 30 days
  Purpose: Obtain new access tokens
  Storage: Secure, HTTP-only cookie
  Rotation: New token on each refresh
  Revocation: Database + Redis blacklist

Token Validation:
  - Signature verification (RS256)
  - Expiration check
  - Issuer validation
  - Audience validation
  - Blacklist check (revoked tokens)

Multi-Factor Authentication (MFA):

Support: TOTP (Time-based One-Time Password)
Apps: Google Authenticator, Authy, Microsoft Authenticator

Enrollment Flow: 1. User enables MFA in settings
  2. System generates secret key
  3. Display QR code
  4. User scans with authenticator app
  5. User enters verification code
  6. System validates and enables MFA

Login Flow: 1. User provides username/password
  2. System validates credentials
  3. Request MFA code
  4. User enters 6-digit code
  5. System validates TOTP
  6. Issue tokens

Backup Codes:
  - 10 single-use backup codes
  - Encrypted storage
  - Regeneration on request

Authorization System

Role-Based Access Control (RBAC):

User → Roles → Permissions → Resources

Standard Roles:

Role Description Typical Permissions
Super Admin Platform administrator All permissions across all tenants
Tenant Admin Organization administrator Manage users, content, settings within tenant
Instructor Course instructor Create/manage courses, grade students, view analytics
Content Creator Content developer Create/edit content, upload files
Student Course participant View content, submit assignments, take assessments
Guest Limited access user View public content only

Permission Model:

Format: {resource}:{action}

Examples:
- files:read         → Read files
- files:write        → Upload/edit files
- files:delete       → Delete files
- files:share        → Share files with others
- courses:create     → Create new courses
- courses:enroll     → Enroll in courses
- users:manage       → Manage user accounts
- grades:submit      → Submit grades
- reports:view       → View reports
- settings:modify    → Change settings

Dynamic Authorization:

async function checkPermission(userId, resource, action) {
  // 1. Get user roles
  const roles = await getUserRoles(userId);

  // 2. Get role permissions
  const permissions = await getRolePermissions(roles);

  // 3. Check resource ownership
  const isOwner = await checkOwnership(userId, resource);

  // 4. Check explicit permissions
  const hasPermission = permissions.includes(`${resource}:${action}`);

  // 5. Check sharing rules
  const isShared = await checkSharing(userId, resource);

  // 6. Evaluate context
  const context = {
    time: new Date(),
    ipAddress: request.ip,
    userAgent: request.headers["user-agent"],
    location: await getLocation(request.ip),
  };

  const contextValid = await evaluateContext(context);

  // 7. Make decision
  return (hasPermission || isOwner || isShared) && contextValid;
}

Permission Caching:

// Cache user permissions for 30 minutes
const cacheKey = `user:perms:${userId}`;
const cached = await redis.get(cacheKey);

if (cached) {
  return JSON.parse(cached);
}

const permissions = await calculatePermissions(userId);
await redis.setex(cacheKey, 1800, JSON.stringify(permissions));

return permissions;

API Security

API Gateway Protection:

1. Authentication:

Method: Bearer Token (JWT)
Header: Authorization: Bearer <token>
Validation:
  - Token signature
  - Token expiration
  - Token revocation status
  - Audience claim
  - Issuer claim

2. Rate Limiting:

Global Limits:
  - 100 requests/minute per user
  - 1,000 requests/minute per tenant
  - 10,000 requests/hour per IP

Endpoint-Specific:
  - /auth/login: 5 attempts/minute
  - /files/upload: 10 uploads/minute
  - /api/search: 30 requests/minute

Implementation:
  - Token bucket algorithm
  - Sliding window counter
  - Redis for distributed rate limiting

Headers:
  X-RateLimit-Limit: 100
  X-RateLimit-Remaining: 95
  X-RateLimit-Reset: 1700000000

3. Input Validation:

const validateFileUpload = (req) => {
  // Size validation
  if (req.file.size > 1500 * 1024 * 1024) {
    throw new Error("File too large");
  }

  // Type validation
  const allowedTypes = [
    "application/pdf",
    "image/jpeg",
    "image/png",
    "application/msword",
  ];

  if (!allowedTypes.includes(req.file.mimetype)) {
    throw new Error("Invalid file type");
  }

  // Filename validation (prevent path traversal)
  const filename = req.file.originalname;
  if (filename.includes("..") || filename.includes("/")) {
    throw new Error("Invalid filename");
  }

  // Scan for malware (future)
  // await scanForMalware(req.file);

  return true;
};

4. SQL Injection Prevention:

// BAD - Vulnerable to SQL injection
const query = `SELECT * FROM files WHERE name = '${userInput}'`;

// GOOD - Parameterized query
const query = "SELECT * FROM files WHERE name = ?";
const results = await db.query(query, [userInput]);

// BETTER - ORM with built-in protection
const results = await File.findAll({
  where: { name: userInput },
});

5. XSS Prevention:

// Input sanitization
const sanitize = require("sanitize-html");

const cleanInput = sanitize(userInput, {
  allowedTags: [],
  allowedAttributes: {},
});

// Output encoding
const escapeHtml = (unsafe) => {
  return unsafe
    .replace(/&/g, "&amp;")
    .replace(/</g, "&lt;")
    .replace(/>/g, "&gt;")
    .replace(/"/g, "&quot;")
    .replace(/'/g, "&#039;");
};

6. CSRF Protection:

Implementation: SameSite cookies + CSRF tokens

Cookies:
  SameSite: Strict (for sensitive operations)
  SameSite: Lax (for general use)
  Secure: true (HTTPS only)
  HttpOnly: true (no JavaScript access)

CSRF Tokens:
  - Unique per session
  - Validated on state-changing operations
  - Synchronized with session

Layer 3: Data Security

Encryption Strategy

Encryption at Rest:

Azure Blob Storage:

Method: Azure Storage Service Encryption (SSE)
Algorithm: AES-256
Key Management:
  - Microsoft-managed keys (default)
  - Customer-managed keys (option)
  - Key rotation: Automatic

Features:
  - Transparent encryption
  - No performance impact
  - Compliance: FIPS 140-2

MySQL Database:

-- Enable Transparent Data Encryption (TDE)
ALTER TABLE files ENCRYPTION='Y';
ALTER TABLE folders ENCRYPTION='Y';
ALTER TABLE permissions ENCRYPTION='Y';

-- Verify encryption
SELECT
  table_name,
  create_options
FROM information_schema.tables
WHERE table_schema = 'kinana_db';

SQL Server Database:

-- Enable TDE
USE master;
CREATE MASTER KEY ENCRYPTION BY PASSWORD = 'StrongPassword123!';

CREATE CERTIFICATE TDECert WITH SUBJECT = 'TDE Certificate';

USE lti_db;
CREATE DATABASE ENCRYPTION KEY
WITH ALGORITHM = AES_256
ENCRYPTION BY SERVER CERTIFICATE TDECert;

ALTER DATABASE lti_db SET ENCRYPTION ON;

Sensitive Data Encryption (Field-Level):

const crypto = require("crypto");

// Encrypt sensitive field
function encryptField(plaintext, key) {
  const iv = crypto.randomBytes(16);
  const cipher = crypto.createCipheriv("aes-256-gcm", key, iv);

  let encrypted = cipher.update(plaintext, "utf8", "hex");
  encrypted += cipher.final("hex");

  const authTag = cipher.getAuthTag();

  return {
    iv: iv.toString("hex"),
    encrypted: encrypted,
    authTag: authTag.toString("hex"),
  };
}

// Decrypt sensitive field
function decryptField(encrypted, key) {
  const decipher = crypto.createDecipheriv(
    "aes-256-gcm",
    key,
    Buffer.from(encrypted.iv, "hex")
  );

  decipher.setAuthTag(Buffer.from(encrypted.authTag, "hex"));

  let decrypted = decipher.update(encrypted.encrypted, "hex", "utf8");
  decrypted += decipher.final("utf8");

  return decrypted;
}

Encryption in Transit:

External Connections:

Protocol: TLS 1.2+ (TLS 1.3 preferred)
Cipher Suites (Preferred Order): 1. TLS_AES_256_GCM_SHA384
  2. TLS_CHACHA20_POLY1305_SHA256
  3. TLS_AES_128_GCM_SHA256
  4. ECDHE-RSA-AES256-GCM-SHA384
  5. ECDHE-RSA-AES128-GCM-SHA256

Certificate Validation:
  - Verify certificate chain
  - Check certificate revocation (OCSP)
  - Validate hostname
  - Check expiration date

Internal Connections:

Current (Unencrypted HTTP):

Service A → HTTP → Service B (within Kubernetes)

Future (Service Mesh with mTLS):

Service A → mTLS → Service B
  ↓                    ↓
  Certificate      Certificate
  (auto-issued)    (auto-issued)

Database Connections:

MySQL:
  - TLS support: Available
  - Certificate validation: Optional
  - Recommended for production

SQL Server:
  - Encryption: Enabled
  - Trust server certificate: true
  - Minimum TLS: 1.2

Redis:
  - TLS support: Available (not enabled)
  - Recommendation: Enable for production

Access Control

Data Classification:

Level Description Examples Controls
Public Non-sensitive, publicly available Marketing materials, public documents Standard encryption
Internal Internal use only Course materials, internal docs Encryption + authentication
Confidential Sensitive business data Student records, grades, PII Encryption + RBAC + audit logging
Restricted Highly sensitive Financial data, SSN, passwords Encryption + MFA + approval + detailed audit

Access Control Matrix:

Role Public Internal Confidential Restricted
Guest
Student Own Only
Instructor Course
Content Creator
Tenant Admin Limited
Super Admin

Time-Limited Access (SAS Tokens):

// Generate time-limited SAS token for file access
function generateSASToken(blobName, permissions, expiryMinutes) {
  const startDate = new Date();
  const expiryDate = new Date(startDate);
  expiryDate.setMinutes(startDate.getMinutes() + expiryMinutes);

  const sharedAccessPolicy = {
    AccessPolicy: {
      Permissions: permissions, // 'r' for read, 'w' for write
      Start: startDate,
      Expiry: expiryDate,
    },
  };

  const sasToken = blobService.generateSharedAccessSignature(
    containerName,
    blobName,
    sharedAccessPolicy
  );

  return sasToken;
}

// Usage: 15-minute read access
const token = generateSASToken("document.pdf", "r", 15);
const url = `${baseUrl}/${blobName}?${token}`;

Data Loss Prevention (DLP)

Sensitive Data Detection:

// Detect PII in text
const patterns = {
  ssn: /\b\d{3}-\d{2}-\d{4}\b/g,
  creditCard: /\b\d{4}[\s-]?\d{4}[\s-]?\d{4}[\s-]?\d{4}\b/g,
  email: /\b[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Z|a-z]{2,}\b/g,
  phone: /\b\d{3}[-.]?\d{3}[-.]?\d{4}\b/g,
};

function detectSensitiveData(text) {
  const findings = [];

  for (const [type, pattern] of Object.entries(patterns)) {
    const matches = text.match(pattern);
    if (matches) {
      findings.push({
        type: type,
        count: matches.length,
        samples: matches.slice(0, 3), // First 3 matches
      });
    }
  }

  return findings;
}

// Redact sensitive data
function redactSensitiveData(text) {
  let redacted = text;

  for (const pattern of Object.values(patterns)) {
    redacted = redacted.replace(pattern, "[REDACTED]");
  }

  return redacted;
}

Data Masking:

// Mask sensitive data in logs
function maskEmail(email) {
  const [name, domain] = email.split("@");
  const masked = name[0] + "*".repeat(name.length - 2) + name[name.length - 1];
  return `${masked}@${domain}`;
}

function maskCreditCard(card) {
  return "*".repeat(12) + card.slice(-4);
}

function maskSSN(ssn) {
  return "***-**-" + ssn.slice(-4);
}

// Log safely
console.log(`User ${maskEmail(user.email)} uploaded file`);

Container Security

Image Security:

Best Practices: 1. Use official base images
  2. Minimal image layers
  3. No secrets in images
  4. Regular security scans
  5. Image signing and verification
  6. Keep images updated

Scanning:
  - Azure Container Registry scanning
  - Trivy for vulnerability scanning
  - Snyk for dependency scanning

Vulnerabilities:
  - Critical: Block deployment
  - High: Review required
  - Medium: Acceptable with plan
  - Low: Informational

Dockerfile Security:

# Use specific version (not latest)
FROM node:18.17.0-alpine AS base

# Create non-root user
RUN addgroup -g 1001 -S nodejs && \
    adduser -S nodejs -u 1001

WORKDIR /app

# Copy package files
COPY --chown=nodejs:nodejs package*.json ./

# Install dependencies
RUN npm ci --only=production && \
    npm cache clean --force

# Copy application files
COPY --chown=nodejs:nodejs . .

# Use non-root user
USER nodejs

# Expose port
EXPOSE 3000

# Health check
HEALTHCHECK --interval=30s --timeout=3s --start-period=5s --retries=3 \
  CMD node healthcheck.js

# Start application
CMD ["node", "server.js"]

Image Scanning:

# Scan with Trivy
trivy image uepcr.azurecr.io/kinanaapi:1.0.0

# Scan with Azure Container Registry
az acr check-health --name uepcr
az acr task run --registry uepcr --name scan-task

Layer 5: Secret Management

Stored Secrets:

Database Credentials:
  - mysql-root-password
  - sql-server-password
  - redis-password (future)

API Keys:
  - azure-storage-key
  - translation-api-key
  - payment-gateway-key

Certificates:
  - legacy-ssl-certificates
  - jwt-signing-key

Service Credentials:
  - smtp-credentials
  - oauth-client-secrets

Access Control:

AKS Managed Identity:
  Permissions: Get, List (Secrets only)
  Scope: Production secrets only

DevOps Service Principal:
  Permissions: Get, List, Set (Secrets)
  Scope: All secrets
  MFA: Required

Admin Users:
  Permissions: All
  MFA: Required
  Approval: Required for sensitive operations

Secret Rotation:

Automatic Rotation:
  - TLS certificates: via cert-manager
  - Database passwords: 90 days
  - API keys: 90 days

Manual Rotation:
  - Encryption keys: Annual
  - Service credentials: Quarterly

Process: 1. Generate new secret
  2. Store in Key Vault
  3. Update applications (zero-downtime)
  4. Verify functionality
  5. Remove old secret after grace period

Kubernetes Secrets

Secret Types:

# Docker registry credentials
kubectl create secret docker-registry uepcr \
  --docker-server=uepcr.azurecr.io \
  --docker-username=$SP_ID \
  --docker-password=$SP_PASSWORD

# TLS certificates (managed by cert-manager)
kubectl create secret tls kinana-api-secret \
  --cert=path/to/cert.pem \
  --key=path/to/key.pem

# Generic secrets
kubectl create secret generic database-credentials \
  --from-literal=username=root \
  --from-literal=password=SecurePassword123

Best Practices:

1. Never commit secrets to Git
2. Use external secrets operator
3. Encrypt secrets at rest (etcd encryption)
4. Limit secret access via RBAC
5. Rotate secrets regularly
6. Audit secret access
7. Use strong encryption
8. Separate secrets by environment

External Secrets Operator (Future):

apiVersion: external-secrets.io/v1beta1
kind: ExternalSecret
metadata:
  name: database-secret
  namespace: kinana-dev
spec:
  refreshInterval: 1h
  secretStoreRef:
    name: azure-key-vault
    kind: SecretStore
  target:
    name: database-credentials
    creationPolicy: Owner
  data:
    - secretKey: password
      remoteRef:
        key: mysql-root-password

Authentication & Authorization Flows

User Authentication Flow

User Authentication Flow

The complete user authentication flow includes session checking, credential validation, optional MFA, token generation, and session creation. The flow ensures secure authentication with multiple validation checkpoints.


API Request Authorization Flow

API Request Authorization Flow

The API authorization flow validates JWT tokens, checks permissions through Redis cache or database, verifies resource ownership, evaluates sharing rules, and makes final authorization decisions based on multiple factors including context evaluation.


LTI Launch Security Flow

LTI Launch Security Flow

The LTI 1.3 launch flow follows OIDC authentication with comprehensive security validations including nonce checking, state verification, JWT signature validation, and JWKS key verification. The flow also includes grade passback via Assignment and Grade Services (AGS) using OAuth 2.0 client credentials flow.
