# Use strong, unique secret keys
SECRET_KEY=your-super-strong-random-secret-key-here-minimum-32-characters

# Use secure database connections
DATABASE_URL=postgresql://username:password@hostname:port/database?sslmode=require

# Enable secure email settings
MAIL_USE_TLS=1
MAIL_USE_SSL=0  # Use TLS instead of SSL

• ✅ Use HTTPS only (no HTTP)
• ✅ Set secure session cookies
• ✅ Enable CSRF protection
• ✅ Use environment variables for secrets
• ✅ Regular security updates
• ✅ Database connection encryption
• ✅ Proper file permissions

• ✅ Enforce strong password policies
• ✅ Regular access reviews
• ✅ Principle of least privilege
• ✅ Monitor failed login attempts
• ✅ Regular user deactivation audits

# Always use parameterized queries
user = User.query.filter_by(username=username).first()  # ✅ Safe
# Never use string formatting for SQL
# user = User.query.filter(f"username = '{username}'")  # ❌ Dangerous

# Validate all user inputs
@app.route('/project/<int:project_id>')  # ✅ Type validation
def view_project(project_id):
    if not isinstance(project_id, int) or project_id <= 0:
        abort(400)

# Use Flask-WTF for form handling
class ProjectForm(FlaskForm):
    name = StringField('Name', validators=[DataRequired(), Length(min=1, max=100)])
    budget = DecimalField('Budget', validators=[NumberRange(min=0)])

# Strong password hashing
from werkzeug.security import generate_password_hash, check_password_hash

def set_password(self, password):
    # Uses PBKDF2 with SHA256 by default
    self.password_hash = generate_password_hash(password)

# Secure session management
@login_required
def protected_view():
    # Automatically enforces authentication
    pass

• Password Hashing: PBKDF2 with SHA256
• Session Management: Flask-Login secure sessions
• Role-Based Access Control: Hierarchical permissions
• CSRF Protection: Automatic token validation

• Form Validation: Flask-WTF with validators
• Type Checking: Route parameter validation
• SQL Injection Prevention: SQLAlchemy ORM
• XSS Protection: Jinja2 auto-escaping

• Environment Variables: Sensitive data isolation
• Database Encryption: Connection-level security
• Session Security: Secure cookie configuration
• File Upload Security: Type and size validation

# Automatically applied security headers
@app.after_request
