# Kanvaro - Enterprise-Grade Security Implementation ## Overview Kanvaro implements enterprise-grade security with production-ready security measures, ensuring data protection, access control, and compliance with industry standards. The security architecture follows defense-in-depth principles with multiple layers of protection. ## Security Architecture ### Defense-in-Depth Strategy ``` ┌─────────────────────────────────────────────────────────┐ │ Security Layers │ ├─────────────────────────────────────────────────────────┤ │ 1. Network Security (Firewall, DDoS Protection) │ │ 2. Application Security (WAF, Rate Limiting) │ │ 3. Authentication & Authorization (JWT, RBAC) │ │ 4. Data Security (Encryption, Hashing) │ │ 5. Infrastructure Security (Container, Secrets) │ │ 6. Monitoring & Logging (SIEM, Audit Trails) │ └─────────────────────────────────────────────────────────┘ ``` ## Authentication & Authorization ### Multi-Factor Authentication (MFA) ```typescript // lib/auth/mfa.ts import { authenticator } from 'otplib'; import QRCode from 'qrcode'; import { z } from 'zod'; const MFASchema = z.object({ userId: z.string().uuid(), secret: z.string(), backupCodes: z.array(z.string()), isEnabled: z.boolean(), lastUsed: z.date().optional(), }); export class MFAService { static generateSecret(userId: string): string { return authenticator.generateSecret(); } static generateQRCode(userId: string, secret: string, issuer: string = 'Kanvaro'): Promise { const otpauth = authenticator.keyuri(userId, issuer, secret); return QRCode.toDataURL(otpauth); } static verifyToken(secret: string, token: string): boolean { try { return authenticator.verify({ token, secret }); } catch { return false; } } static generateBackupCodes(): string[] { return Array.from({ length: 10 }, () => Math.random().toString(36).substring(2, 10).toUpperCase() ); } static verifyBackupCode(userId: string, code: string): boolean { // Implementation to verify backup codes const user = getUserById(userId); return user.backupCodes.includes(code); } } ``` ### Role-Based Access Control (RBAC) ```typescript // lib/auth/rbac.ts export enum Permission { // Project permissions PROJECT_CREATE = 'project:create', PROJECT_READ = 'project:read', PROJECT_UPDATE = 'project:update', PROJECT_DELETE = 'project:delete', PROJECT_ADMIN = 'project:admin', // Task permissions TASK_CREATE = 'task:create', TASK_READ = 'task:read', TASK_UPDATE = 'task:update', TASK_DELETE = 'task:delete', TASK_ASSIGN = 'task:assign', // Team permissions TEAM_READ = 'team:read', TEAM_INVITE = 'team:invite', TEAM_REMOVE = 'team:remove', TEAM_ADMIN = 'team:admin', // Financial permissions BUDGET_READ = 'budget:read', BUDGET_UPDATE = 'budget:update', INVOICE_CREATE = 'invoice:create', INVOICE_READ = 'invoice:read', // System permissions SYSTEM_ADMIN = 'system:admin', USER_MANAGE = 'user:manage', SETTINGS_UPDATE = 'settings:update', } export enum Role { SUPER_ADMIN = 'super_admin', ADMIN = 'admin', PROJECT_MANAGER = 'project_manager', TEAM_MEMBER = 'team_member', CLIENT = 'client', VIEWER = 'viewer', } export const ROLE_PERMISSIONS: Record = { [Role.SUPER_ADMIN]: Object.values(Permission), [Role.ADMIN]: [ Permission.PROJECT_CREATE, Permission.PROJECT_READ, Permission.PROJECT_UPDATE, Permission.PROJECT_DELETE, Permission.TASK_CREATE, Permission.TASK_READ, Permission.TASK_UPDATE, Permission.TASK_DELETE, Permission.TEAM_READ, Permission.TEAM_INVITE, Permission.TEAM_REMOVE, Permission.BUDGET_READ, Permission.BUDGET_UPDATE, Permission.INVOICE_CREATE, Permission.INVOICE_READ, Permission.USER_MANAGE, Permission.SETTINGS_UPDATE, ], [Role.PROJECT_MANAGER]: [ Permission.PROJECT_CREATE, Permission.PROJECT_READ, Permission.PROJECT_UPDATE, Permission.TASK_CREATE, Permission.TASK_READ, Permission.TASK_UPDATE, Permission.TASK_ASSIGN, Permission.TEAM_READ, Permission.TEAM_INVITE, Permission.BUDGET_READ, Permission.BUDGET_UPDATE, Permission.INVOICE_CREATE, Permission.INVOICE_READ, ], [Role.TEAM_MEMBER]: [ Permission.PROJECT_READ, Permission.TASK_CREATE, Permission.TASK_READ, Permission.TASK_UPDATE, Permission.TEAM_READ, ], [Role.CLIENT]: [ Permission.PROJECT_READ, Permission.TASK_READ, ], [Role.VIEWER]: [ Permission.PROJECT_READ, Permission.TASK_READ, Permission.TEAM_READ, ], }; export class RBACService { static hasPermission(userRole: Role, permission: Permission): boolean { const rolePermissions = ROLE_PERMISSIONS[userRole] || []; return rolePermissions.includes(permission); } static hasAnyPermission(userRole: Role, permissions: Permission[]): boolean { return permissions.some(permission => this.hasPermission(userRole, permission)); } static hasAllPermissions(userRole: Role, permissions: Permission[]): boolean { return permissions.every(permission => this.hasPermission(userRole, permission)); } static canAccessResource(userRole: Role, resource: string, action: string): boolean { const permission = `${resource}:${action}` as Permission; return this.hasPermission(userRole, permission); } } ``` ### JWT Token Security ```typescript // lib/auth/jwt.ts import jwt from 'jsonwebtoken'; import { z } from 'zod'; const JWT_SECRET = process.env.JWT_SECRET!; const JWT_REFRESH_SECRET = process.env.JWT_REFRESH_SECRET!; const JWT_EXPIRES_IN = process.env.JWT_EXPIRES_IN || '15m'; const JWT_REFRESH_EXPIRES_IN = process.env.JWT_REFRESH_EXPIRES_IN || '7d'; const TokenPayloadSchema = z.object({ userId: z.string().uuid(), email: z.string().email(), role: z.string(), organizationId: z.string().uuid(), permissions: z.array(z.string()), iat: z.number(), exp: z.number(), }); export class JWTService { static generateAccessToken(payload: { userId: string; email: string; role: string; organizationId: string; permissions: string[]; }): string { return jwt.sign(payload, JWT_SECRET, { expiresIn: JWT_EXPIRES_IN, issuer: 'kanvaro', audience: 'kanvaro-users', }); } static generateRefreshToken(payload: { userId: string; email: string; organizationId: string; }): string { return jwt.sign(payload, JWT_REFRESH_SECRET, { expiresIn: JWT_REFRESH_EXPIRES_IN, issuer: 'kanvaro', audience: 'kanvaro-users', }); } static verifyAccessToken(token: string): any { try { return jwt.verify(token, JWT_SECRET, { issuer: 'kanvaro', audience: 'kanvaro-users', }); } catch (error) { throw new Error('Invalid access token'); } } static verifyRefreshToken(token: string): any { try { return jwt.verify(token, JWT_REFRESH_SECRET, { issuer: 'kanvaro', audience: 'kanvaro-users', }); } catch (error) { throw new Error('Invalid refresh token'); } } static decodeToken(token: string): any { return jwt.decode(token); } static isTokenExpired(token: string): boolean { try { const decoded = jwt.decode(token) as any; return decoded.exp < Date.now() / 1000; } catch { return true; } } } ``` ## Data Security ### Encryption at Rest and in Transit ```typescript // lib/security/encryption.ts import crypto from 'crypto'; import bcrypt from 'bcrypt'; export class EncryptionService { private static readonly ALGORITHM = 'aes-256-gcm'; private static readonly KEY_LENGTH = 32; private static readonly IV_LENGTH = 16; private static readonly SALT_LENGTH = 16; private static readonly TAG_LENGTH = 16; static generateKey(): string { return crypto.randomBytes(this.KEY_LENGTH).toString('hex'); } static encrypt(text: string, key: string): string { const iv = crypto.randomBytes(this.IV_LENGTH); const cipher = crypto.createCipher(this.ALGORITHM, key); cipher.setAAD(Buffer.from('kanvaro', 'utf8')); let encrypted = cipher.update(text, 'utf8', 'hex'); encrypted += cipher.final('hex'); const tag = cipher.getAuthTag(); return iv.toString('hex') + ':' + tag.toString('hex') + ':' + encrypted; } static decrypt(encryptedText: string, key: string): string { const parts = encryptedText.split(':'); const iv = Buffer.from(parts[0], 'hex'); const tag = Buffer.from(parts[1], 'hex'); const encrypted = parts[2]; const decipher = crypto.createDecipher(this.ALGORITHM, key); decipher.setAAD(Buffer.from('kanvaro', 'utf8')); decipher.setAuthTag(tag); let decrypted = decipher.update(encrypted, 'hex', 'utf8'); decrypted += decipher.final('utf8'); return decrypted; } static hashPassword(password: string): Promise { return bcrypt.hash(password, 12); } static verifyPassword(password: string, hash: string): Promise { return bcrypt.compare(password, hash); } static generateSecureToken(length: number = 32): string { return crypto.randomBytes(length).toString('hex'); } static hashSensitiveData(data: string): string { return crypto.createHash('sha256').update(data).digest('hex'); } } ``` ### Database Security ```typescript // lib/security/database.ts import mongoose from 'mongoose'; import { EncryptionService } from './encryption'; // Encrypted field plugin export const encryptedField = (schema: mongoose.Schema, field: string) => { schema.pre('save', function(next) { if (this.isModified(field)) { this[field] = EncryptionService.encrypt(this[field], process.env.ENCRYPTION_KEY!); } next(); }); schema.post('init', function() { if (this[field]) { this[field] = EncryptionService.decrypt(this[field], process.env.ENCRYPTION_KEY!); } }); }; // Audit trail plugin export const auditTrail = (schema: mongoose.Schema) => { schema.add({ createdBy: { type: mongoose.Schema.Types.ObjectId, ref: 'User' }, updatedBy: { type: mongoose.Schema.Types.ObjectId, ref: 'User' }, createdAt: { type: Date, default: Date.now }, updatedAt: { type: Date, default: Date.now }, version: { type: Number, default: 1 }, }); schema.pre('save', function(next) { this.updatedAt = new Date(); this.version += 1; next(); }); }; // Row-level security export const rowLevelSecurity = (schema: mongoose.Schema, organizationField: string = 'organization') => { schema.pre(/^find/, function() { const user = this.getOptions().user; if (user && user.role !== 'super_admin') { this.where({ [organizationField]: user.organizationId }); } }); }; ``` ## API Security ### Rate Limiting ```typescript // lib/security/rate-limiting.ts import { NextRequest, NextResponse } from 'next/server'; import { Redis } from 'ioredis'; const redis = new Redis(process.env.REDIS_URL!); export class RateLimiter { static async checkLimit( key: string, limit: number, windowMs: number ): Promise<{ allowed: boolean; remaining: number; resetTime: number }> { const now = Date.now(); const window = Math.floor(now / windowMs); const redisKey = `rate_limit:${key}:${window}`; const current = await redis.incr(redisKey); await redis.expire(redisKey, Math.ceil(windowMs / 1000)); const remaining = Math.max(0, limit - current); const resetTime = (window + 1) * windowMs; return { allowed: current <= limit, remaining, resetTime }; } static async middleware( request: NextRequest, limit: number = 100, windowMs: number = 15 * 60 * 1000 // 15 minutes ): Promise { const ip = request.ip || request.headers.get('x-forwarded-for') || 'unknown'; const userAgent = request.headers.get('user-agent') || 'unknown'; const key = `${ip}:${userAgent}`; const result = await this.checkLimit(key, limit, windowMs); if (!result.allowed) { return NextResponse.json( { error: 'Rate limit exceeded' }, { status: 429, headers: { 'X-RateLimit-Limit': limit.toString(), 'X-RateLimit-Remaining': result.remaining.toString(), 'X-RateLimit-Reset': result.resetTime.toString(), } } ); } return null; } } ``` ### Input Validation & Sanitization ```typescript // lib/security/validation.ts import { z } from 'zod'; import DOMPurify from 'isomorphic-dompurify'; export class SecurityValidator { static sanitizeHtml(html: string): string { return DOMPurify.sanitize(html, { ALLOWED_TAGS: ['b', 'i', 'em', 'strong', 'p', 'br'], ALLOWED_ATTR: [] }); } static sanitizeInput(input: string): string { return input .replace(/[<>]/g, '') // Remove potential HTML tags .replace(/javascript:/gi, '') // Remove javascript: protocol .replace(/on\w+=/gi, '') // Remove event handlers .trim(); } static validateEmail(email: string): boolean { const emailRegex = /^[^\s@]+@[^\s@]+\.[^\s@]+$/; return emailRegex.test(email) && email.length <= 254; } static validatePassword(password: string): { isValid: boolean; errors: string[]; } { const errors: string[] = []; if (password.length < 8) { errors.push('Password must be at least 8 characters long'); } if (!/[A-Z]/.test(password)) { errors.push('Password must contain at least one uppercase letter'); } if (!/[a-z]/.test(password)) { errors.push('Password must contain at least one lowercase letter'); } if (!/\d/.test(password)) { errors.push('Password must contain at least one number'); } if (!/[!@#$%^&*(),.?":{}|<>]/.test(password)) { errors.push('Password must contain at least one special character'); } return { isValid: errors.length === 0, errors }; } static validateUUID(uuid: string): boolean { const uuidRegex = /^[0-9a-f]{8}-[0-9a-f]{4}-[1-5][0-9a-f]{3}-[89ab][0-9a-f]{3}-[0-9a-f]{12}$/i; return uuidRegex.test(uuid); } } // Zod schemas for API validation export const SecuritySchemas = { user: z.object({ email: z.string().email().max(254), password: z.string().min(8).max(128), firstName: z.string().min(1).max(50).regex(/^[a-zA-Z\s]+$/), lastName: z.string().min(1).max(50).regex(/^[a-zA-Z\s]+$/), }), project: z.object({ name: z.string().min(1).max(100).regex(/^[a-zA-Z0-9\s\-_]+$/), description: z.string().max(1000).optional(), status: z.enum(['planning', 'active', 'on-hold', 'completed', 'cancelled']), }), task: z.object({ title: z.string().min(1).max(200), description: z.string().max(10000).optional(), priority: z.enum(['low', 'medium', 'high', 'critical']), status: z.enum(['todo', 'in-progress', 'review', 'done', 'cancelled']), }), };

} static validateSecrets(): void { const requiredSecrets = [ 'JWT_SECRET', 'JWT_REFRESH_SECRET', 'MONGODB_URI', 'REDIS_URL', 'ENCRYPTION_KEY', ]; const missing = requiredSecrets.filter(secret => !process.env[secret]); if (missing.length > 0) { throw new Error(`Missing required secrets: ${missing.join(', ')}`); } } static rotateSecret(oldSecret: string, newSecret: string): void { // Implementation for secret rotation // This would involve updating the secret and re-encrypting data } } ``` ## Monitoring & Logging ### Security Event Logging ```typescript // lib/security/logging.ts import { Logger } from 'winston';
