📋 Setup Instructions

Prerequisites

• Node.js 18+
• npm or yarn
• Supabase account
• GitHub account (for CI/CD)

Local Development

1. Clone the repository

   git clone https://github.com/MR-PROFESSOR-790/SecureTasker
   cd securetasker

2. Install dependencies

   npm install

3. Environment Setup Create a .env.local file:

   NEXT_PUBLIC_SUPABASE_URL=your_supabase_url
   NEXT_PUBLIC_SUPABASE_ANON_KEY=your_supabase_anon_key

4. Database Setup

   • Run the SQL scripts in the scripts/ folder in your Supabase SQL editor
   • This creates the tasks table with proper RLS policies

5. Run the development server

   npm run dev

6. Access the application Open http://localhost:3000 in your browser

Production Deployment

1. Vercel Deployment

   npm run build
   vercel --prod

2. Environment Variables Set the following in your Vercel dashboard:

   • NEXT_PUBLIC_SUPABASE_URL
   • NEXT_PUBLIC_SUPABASE_ANON_KEY

🔍 Security Implementation Details

Input Validation

const taskSchema = z.object({
  title: z.string().min(1).max(100),
  description: z.string().max(500).optional(),
  priority: z.enum(['low', 'medium', 'high']),
  status: z.enum(['pending', 'in_progress', 'completed'])
})

Security Headers

const securityHeaders = {
  'X-XSS-Protection': '1; mode=block',
  'X-Content-Type-Options': 'nosniff',
  'X-Frame-Options': 'DENY',
  'Content-Security-Policy': 'default-src \'self\'; ...',
  'Strict-Transport-Security': 'max-age=31536000; includeSubDomains'
}

Row Level Security (RLS)

CREATE POLICY "Users can only see their own tasks" ON tasks
    FOR SELECT USING (auth.uid() = user_id);

📊 Security Testing Results

Static Analysis

• Bandit: Python security linter results
• ESLint Security: JavaScript security rule violations
• npm audit: Dependency vulnerability scan

Dynamic Testing

• OWASP ZAP: Automated security testing
• Manual Penetration Testing: Security assessment results
