Principle of Least Privilege

Grant minimum permissions required for each role:

// ✅ Good: Minimal permissions
const userPermissions = {
  viewer: ['events:read', 'deliverables:read'],
  user: ['events:read', 'deliverables:read', 'deliverables:update'],
  manager: ['events:*', 'deliverables:*', 'reports:read'],
  admin: ['*'],
};

// ❌ Bad: Overly permissive
const userPermissions = {
  user: ['*'], // Too broad
};

Fail Secure

When errors occur, default to secure state:

// ✅ Good: Fail secure
async function checkPermission(userId: string, resource: string): Promise<boolean> {
  try {
    const permissions = await fetchUserPermissions(userId);
    return permissions.includes(resource);
  } catch (error) {
    // Default to denied on error
    console.error('Permission check failed:', error);
    return false;
  }
}

// ❌ Bad: Fail open
async function checkPermission(userId: string, resource: string): Promise<boolean> {
  try {
    const permissions = await fetchUserPermissions(userId);
    return permissions.includes(resource);
  } catch (error) {
    // Dangerous: grants access on error
    return true;
  }
}

Authentication

Azure AD Integration

Use MSAL (Microsoft Authentication Library) for authentication:

// src/lib/auth/msalConfig.ts
import { Configuration, LogLevel } from '@azure/msal-browser';

export const msalConfig: Configuration = {
  auth: {
    clientId: import.meta.env.VITE_AZURE_CLIENT_ID,
    authority: `https://login.microsoftonline.com/${import.meta.env.VITE_AZURE_TENANT_ID}`,
    redirectUri: window.location.origin,
    postLogoutRedirectUri: window.location.origin,
  },
  cache: {
    cacheLocation: 'sessionStorage', // More secure than localStorage
    storeAuthStateInCookie: false,
  },
  system: {
    loggerOptions: {
      logLevel: import.meta.env.PROD ? LogLevel.Error : LogLevel.Warning,
      loggerCallback: (level, message) => {
        console.log(message);
      },
    },
  },
};

export const loginRequest = {
  scopes: ['User.Read', 'api://flowstate/access'],
};

Token Management

// src/lib/auth/tokenManager.ts
import { PublicClientApplication } from '@azure/msal-browser';
import { msalConfig, loginRequest } from './msalConfig';

const msalInstance = new PublicClientApplication(msalConfig);

export async function getAccessToken(): Promise<string | null> {
  const account = msalInstance.getActiveAccount();
  if (!account) return null;

  try {
    // Try silent token acquisition first
    const response = await msalInstance.acquireTokenSilent({
      ...loginRequest,
      account,
    });
    return response.accessToken;
  } catch (error) {
    // Fall back to interactive if silent fails
    try {
      const response = await msalInstance.acquireTokenPopup(loginRequest);
      return response.accessToken;
    } catch (interactiveError) {
      console.error('Authentication failed:', interactiveError);
      return null;
    }
  }
}

// Token refresh handling
export function setupTokenRefresh(): void {
  // Refresh token 5 minutes before expiry
  const REFRESH_BUFFER = 5 * 60 * 1000;

  setInterval(async () => {
    const account = msalInstance.getActiveAccount();
    if (!account) return;

    const tokenExpiresAt = account.idTokenClaims?.exp;
    if (!tokenExpiresAt) return;

    const expiryTime = tokenExpiresAt * 1000;
    const now = Date.now();

    if (expiryTime - now < REFRESH_BUFFER) {
      await getAccessToken(); // This will refresh the token
    }
  }, 60 * 1000); // Check every minute
}

Multi-Factor Authentication

MFA is enforced at the Azure AD level. Conditional access policies should require MFA for:

• All administrative actions
• Access from new devices
• Access from unusual locations
• Sensitive data access

Authorization

Role-Based Access Control (RBAC)

// src/types/auth.ts
export type Role = 'admin' | 'manager' | 'user' | 'viewer';

export interface User {
  id: string;
  email: string;
  name: string;
  role: Role;
  permissions: string[];
  groups: string[];
}

// Permission definitions
export const PERMISSIONS = {
  // Events
  EVENTS_CREATE: 'events:create',
  EVENTS_READ: 'events:read',
  EVENTS_UPDATE: 'events:update',
  EVENTS_DELETE: 'events:delete',

  // Deliverables
  DELIVERABLES_CREATE: 'deliverables:create',
  DELIVERABLES_READ: 'deliverables:read',
  DELIVERABLES_UPDATE: 'deliverables:update',
  DELIVERABLES_DELETE: 'deliverables:delete',
  DELIVERABLES_APPROVE: 'deliverables:approve',

  // Reports
  REPORTS_READ: 'reports:read',
  REPORTS_EXPORT: 'reports:export',

  // Admin
  ADMIN_USERS: 'admin:users',
  ADMIN_SETTINGS: 'admin:settings',
  ADMIN_AUDIT: 'admin:audit',
} as const;

// Role to permissions mapping
export const ROLE_PERMISSIONS: Record<Role, string[]> = {
  admin: Object.values(PERMISSIONS),
  manager: [
    PERMISSIONS.EVENTS_CREATE,
    PERMISSIONS.EVENTS_READ,
    PERMISSIONS.EVENTS_UPDATE,
    PERMISSIONS.DELIVERABLES_CREATE,
    PERMISSIONS.DELIVERABLES_READ,
    PERMISSIONS.DELIVERABLES_UPDATE,
    PERMISSIONS.DELIVERABLES_APPROVE,
    PERMISSIONS.REPORTS_READ,
    PERMISSIONS.REPORTS_EXPORT,
  ],
  user: [
    PERMISSIONS.EVENTS_READ,
    PERMISSIONS.DELIVERABLES_READ,
    PERMISSIONS.DELIVERABLES_UPDATE,
    PERMISSIONS.REPORTS_READ,
  ],
  viewer: [
    PERMISSIONS.EVENTS_READ,
    PERMISSIONS.DELIVERABLES_READ,
  ],
};

Permission Hooks

// src/hooks/usePermissions.ts
import { useAuth } from './useAuth';
import { ROLE_PERMISSIONS } from '@/types/auth';

export function usePermission(permission: string): boolean {
  const { user } = useAuth();

  if (!user) return false;

  // Check role-based permissions
  const rolePermissions = ROLE_PERMISSIONS[user.role] || [];
  if (rolePermissions.includes(permission)) return true;

  // Check user-specific permissions
  return user.permissions.includes(permission);
}

export function usePermissions(permissions: string[]): boolean[] {
  const { user } = useAuth();

  if (!user) return permissions.map(() => false);

  return permissions.map((permission) => {
    const rolePermissions = ROLE_PERMISSIONS[user.role] || [];
    return rolePermissions.includes(permission) || user.permissions.includes(permission);
  });
}

// Permission guard component
export function RequirePermission({
  permission,
  children,
  fallback = null,
}: {
  permission: string;
  children: React.ReactNode;
  fallback?: React.ReactNode;
}) {
  const hasPermission = usePermission(permission);

  if (!hasPermission) return <>{fallback}</>;

  return <>{children}</>;
}

Route Protection

// src/components/guards/AuthGuard.tsx
import { Navigate, useLocation } from 'react-router-dom';
import { useAuth } from '@/hooks/useAuth';

interface AuthGuardProps {
  children: React.ReactNode;
  requiredPermission?: string;
  requiredRole?: Role;
}

export function AuthGuard({
  children,
  requiredPermission,
  requiredRole,
}: AuthGuardProps) {
  const { user, loading } = useAuth();
  const location = useLocation();

  if (loading) {
    return <LoadingScreen />;
  }

  if (!user) {
    return <Navigate to="/login" state={{ from: location }} replace />;
  }

  if (requiredRole && user.role !== requiredRole && user.role !== 'admin') {
    return <Navigate to="/unauthorized" replace />;
  }

  if (requiredPermission && !usePermission(requiredPermission)) {
    return <Navigate to="/unauthorized" replace />;
  }

  return <>{children}</>;
}

Data Security

Data Classification

Encryption Standards

// Data encryption utilities
import CryptoJS from 'crypto-js';

// Client-side encryption for sensitive fields (when needed)
export function encryptSensitiveData(data: string, key: string): string {
  return CryptoJS.AES.encrypt(data, key).toString();
}

export function decryptSensitiveData(encryptedData: string, key: string): string {
  const bytes = CryptoJS.AES.decrypt(encryptedData, key);
  return bytes.toString(CryptoJS.enc.Utf8);
}

// Hash sensitive data for logging
export function hashForLogging(sensitiveValue: string): string {
  return CryptoJS.SHA256(sensitiveValue).toString().substring(0, 8) + '...';
}

Data Handling Rules

// ❌ Never log sensitive data
console.log('User password:', password); // DANGEROUS

// ✅ Log sanitized data
console.log('Login attempt for user:', hashForLogging(email));

// ❌ Never store credentials in code
const API_KEY = 'your-secret-key-here'; // DANGEROUS - never hardcode!

// ✅ Use environment variables
const API_KEY = import.meta.env.VITE_API_KEY;

// ❌ Never expose tokens in URLs
const url = `/api/data?token=${token}`; // DANGEROUS

// ✅ Use headers for authentication
const response = await fetch('/api/data', {
  headers: { Authorization: `Bearer ${token}` },
});

Input Validation

Validation with Zod

// src/lib/validation/schemas.ts
import { z } from 'zod';

// Event validation schema
export const eventSchema = z.object({
  name: z
    .string()
    .min(1, 'Name is required')
    .max(200, 'Name must be 200 characters or less')
    .regex(/^[\w\s\-.,!?()]+$/, 'Name contains invalid characters'),

  description: z
    .string()
    .max(2000, 'Description must be 2000 characters or less')
    .optional(),

  startDate: z
    .date()
    .min(new Date('2020-01-01'), 'Start date cannot be before 2020'),

  endDate: z.date(),

  status: z.enum(['on-track', 'at-risk', 'delayed']),

  location: z
    .string()
    .min(1, 'Location is required')
    .max(200, 'Location must be 200 characters or less'),
}).refine((data) => data.endDate >= data.startDate, {
  message: 'End date must be after start date',
  path: ['endDate'],
});

// User input sanitization
export const sanitizeInput = (input: string): string => {
  return input
    .trim()
    .replace(/[<>]/g, '') // Remove potential HTML tags
    .slice(0, 10000); // Limit length
};

// Email validation
export const emailSchema = z
  .string()
  .email('Invalid email address')
  .toLowerCase()
  .max(254, 'Email too long');

// File upload validation
export const fileUploadSchema = z.object({
  name: z.string().max(255),
  size: z.number().max(10 * 1024 * 1024, 'File must be less than 10MB'),
  type: z.enum([
    'application/pdf',
    'application/msword',
    'application/vnd.openxmlformats-officedocument.wordprocessingml.document',
    'image/png',
    'image/jpeg',
  ], { errorMap: () => ({ message: 'Invalid file type' }) }),
});

Form Validation

// src/components/forms/EventForm.tsx
import { useForm } from 'react-hook-form';
import { zodResolver } from '@hookform/resolvers/zod';
import { eventSchema } from '@/lib/validation/schemas';

type EventFormData = z.infer<typeof eventSchema>;

export function EventForm({ onSubmit }: { onSubmit: (data: EventFormData) => void }) {
  const form = useForm<EventFormData>({
    resolver: zodResolver(eventSchema),
    defaultValues: {
      name: '',
      description: '',
      status: 'on-track',
      location: '',
    },
  });

  return (
    <form onSubmit={form.handleSubmit(onSubmit)}>
      {/* Form fields with validation */}
      <input
        {...form.register('name')}
        aria-invalid={!!form.formState.errors.name}
      />
      {form.formState.errors.name && (
        <span role="alert">{form.formState.errors.name.message}</span>
      )}
    </form>
  );
}

SQL Injection Prevention

// Backend: Use parameterized queries
// ✅ Safe: Parameterized query
const result = await db.query(
  'SELECT * FROM events WHERE id = $1 AND status = $2',
  [eventId, status]
);

// ❌ Dangerous: String concatenation
const result = await db.query(
  `SELECT * FROM events WHERE id = '${eventId}'` // SQL INJECTION RISK!
);

// Parse Server: Use query constraints
// ✅ Safe: Parse Query
const query = new Parse.Query('Event');
query.equalTo('id', eventId);
query.equalTo('status', status);
const results = await query.find();

Output Encoding

XSS Prevention

React automatically escapes content, but be careful with:

// ✅ Safe: React auto-escapes
<div>{userContent}</div>

// ⚠️ Dangerous: dangerouslySetInnerHTML
<div dangerouslySetInnerHTML={{ __html: userContent }} /> // XSS RISK!

// ✅ If HTML is required, sanitize first
import DOMPurify from 'dompurify';

const sanitizedHtml = DOMPurify.sanitize(userContent, {
  ALLOWED_TAGS: ['b', 'i', 'em', 'strong', 'a', 'p', 'br'],
  ALLOWED_ATTR: ['href'],
});

<div dangerouslySetInnerHTML={{ __html: sanitizedHtml }} />

URL Handling

// ✅ Safe: Validate URLs
const isValidUrl = (url: string): boolean => {
  try {
    const parsed = new URL(url);
    return ['http:', 'https:'].includes(parsed.protocol);
  } catch {
    return false;
  }
};

// ✅ Safe: Use href only after validation
{isValidUrl(link.url) && (
  <a href={link.url} rel="noopener noreferrer" target="_blank">
    {link.text}
  </a>
)}

// ❌ Dangerous: Unvalidated URL
<a href={userProvidedUrl}>Click here</a> // Could be javascript: protocol

Session Management

Session Security

// Session configuration
const SESSION_CONFIG = {
  // Session timeout: 8 hours for interactive sessions
  INTERACTIVE_TIMEOUT: 8 * 60 * 60 * 1000,

  // Idle timeout: 30 minutes of inactivity
  IDLE_TIMEOUT: 30 * 60 * 1000,

  // Absolute timeout: 24 hours maximum
  ABSOLUTE_TIMEOUT: 24 * 60 * 60 * 1000,
};

// Session management hook
export function useSessionManagement() {
  const { logout } = useAuth();
  const lastActivityRef = useRef(Date.now());

  useEffect(() => {
    // Track user activity
    const updateActivity = () => {
      lastActivityRef.current = Date.now();
    };

    const events = ['mousedown', 'keydown', 'scroll', 'touchstart'];
    events.forEach((event) => window.addEventListener(event, updateActivity));

    // Check for idle timeout
    const interval = setInterval(() => {
      const idleTime = Date.now() - lastActivityRef.current;
      if (idleTime > SESSION_CONFIG.IDLE_TIMEOUT) {
        logout();
        toast.warning('Session expired due to inactivity');
      }
    }, 60 * 1000);

    return () => {
      events.forEach((event) => window.removeEventListener(event, updateActivity));
      clearInterval(interval);
    };
  }, [logout]);
}

Secure Storage

// Use sessionStorage over localStorage for sensitive data
// sessionStorage is cleared when tab closes

// ✅ Safe: Session-scoped storage
sessionStorage.setItem('authToken', token);

// ⚠️ Caution: Persistent storage
localStorage.setItem('authToken', token); // Survives browser close

// For tokens, prefer HttpOnly cookies (set by backend)
// For non-sensitive preferences, localStorage is acceptable
localStorage.setItem('theme', 'dark'); // OK - not sensitive

API Security

Request Security

// src/lib/api.ts
import axios from 'axios';

export const apiClient = axios.create({
  baseURL: import.meta.env.VITE_API_URL,
  timeout: 30000,
  withCredentials: true, // Include cookies for CSRF
  headers: {
    'Content-Type': 'application/json',
  },
});

// Add CSRF token to requests
apiClient.interceptors.request.use((config) => {
  const csrfToken = document.querySelector('meta[name="csrf-token"]')?.getAttribute('content');
  if (csrfToken) {
    config.headers['X-CSRF-Token'] = csrfToken;
  }
  return config;
});

// Add correlation ID for request tracing
apiClient.interceptors.request.use((config) => {
  config.headers['X-Correlation-ID'] = crypto.randomUUID();
  return config;
});

Rate Limiting

// Backend rate limiting configuration
const rateLimitConfig = {
  // General API requests
  general: {
    windowMs: 60 * 1000, // 1 minute
    max: 100, // 100 requests per minute
  },

  // Authentication endpoints
  auth: {
    windowMs: 15 * 60 * 1000, // 15 minutes
    max: 5, // 5 attempts per 15 minutes
  },

  // File uploads
  uploads: {
    windowMs: 60 * 1000,
    max: 10, // 10 uploads per minute
  },
};

Response Security Headers

// Backend: Security headers middleware
app.use((req, res, next) => {
  // Prevent MIME sniffing
  res.setHeader('X-Content-Type-Options', 'nosniff');

  // Prevent clickjacking
  res.setHeader('X-Frame-Options', 'DENY');

  // XSS protection (legacy browsers)
  res.setHeader('X-XSS-Protection', '1; mode=block');

  // Content Security Policy
  res.setHeader('Content-Security-Policy', [
    "default-src 'self'",
    "script-src 'self' 'unsafe-inline'",
    "style-src 'self' 'unsafe-inline'",
    "img-src 'self' data: https:",
    "font-src 'self'",
    "connect-src 'self' https://api.example.com",
    "frame-ancestors 'none'",
  ].join('; '));

  // Strict Transport Security
  res.setHeader('Strict-Transport-Security', 'max-age=31536000; includeSubDomains');

  // Referrer Policy
  res.setHeader('Referrer-Policy', 'strict-origin-when-cross-origin');

  next();
});

Frontend Security

Content Security Policy

<!-- index.html -->
<meta http-equiv="Content-Security-Policy" content="
  default-src 'self';
  script-src 'self';
  style-src 'self' 'unsafe-inline';
  img-src 'self' data: https:;

Secure Component Patterns

// Avoid exposing sensitive data in component state
// ❌ Bad: Storing sensitive data in component
const [creditCard, setCreditCard] = useState(user.creditCard);

// ✅ Good: Only store what's needed
const [last4Digits] = useState(user.cardLast4);

// Prevent sensitive data in console/devtools
if (import.meta.env.PROD) {
  console.log = () => {};
  console.debug = () => {};
}

// Secure event handlers
const handleSubmit = async (data: FormData) => {
  try {
    await submitForm(data);
  } catch (error) {
    // Don't expose internal errors to users
    if (error instanceof ValidationError) {
      setError(error.message);
    } else {
      setError('An unexpected error occurred. Please try again.');
      // Log full error server-side
      logError(error);
    }
  }
};

Dependency Security

Dependency Management

  "scripts": {
    "audit": "npm audit",
    "audit:fix": "npm audit fix",
    "audit:ci": "npm audit --audit-level=high",
    "deps:check": "npm-check-updates",
