Install Required Libraries

First, install the necessary libraries via pip:

bashCopy codepip install flask flask-sqlalchemy flask-login flask-wtf
  • Flask-SQLAlchemy: For database management.
  • Flask-WTF: For form handling.
  • Flask-Login: For user authentication.

Step 2: Define the Database Models

We need three models for this application:

  1. User: To store user information.
  2. CybersecurityAssessment: To store the results of cybersecurity assessments.
  3. CybersecurityInsurancePolicy: To store the insurance policy details and discounts.

models.py

pythonCopy codefrom flask_sqlalchemy import SQLAlchemy
from datetime import datetime

db = SQLAlchemy()

# User model
class User(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    username = db.Column(db.String(100), unique=True, nullable=False)
    email = db.Column(db.String(120), unique=True, nullable=False)
    password_hash = db.Column(db.String(128), nullable=False)
    assessments = db.relationship('CybersecurityAssessment', backref='user', lazy=True)
    policy = db.relationship('CybersecurityInsurancePolicy', backref='user', uselist=False)

    def __repr__(self):
        return f'<User {self.username}>'

# Cybersecurity Assessment model
class CybersecurityAssessment(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    score = db.Column(db.Integer, nullable=False)  # Risk assessment score (e.g., 0-100)
    date = db.Column(db.DateTime, default=datetime.utcnow)
    user_id = db.Column(db.Integer, db.ForeignKey('user.id'), nullable=False)

    def __repr__(self):
        return f'<CybersecurityAssessment {self.score}>'

# Cybersecurity Insurance Policy model
class CybersecurityInsurancePolicy(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    premium = db.Column(db.Float, nullable=False)  # Insurance premium amount
    discount_percentage = db.Column(db.Float, nullable=False)  # Discount based on cybersecurity score
    user_id = db.Column(db.Integer, db.ForeignKey('user.id'), nullable=False)

    def __repr__(self):
        return f'<CybersecurityInsurancePolicy {self.premium}>'

Step 3: Flask Application Setup

Now we’ll set up the Flask application with routes for user registration, login, cybersecurity assessments, and insurance policy calculation.

app.py

pythonCopy codefrom flask import Flask, render_template, redirect, url_for, request, flash
from flask_sqlalchemy import SQLAlchemy
from flask_login import LoginManager, UserMixin, login_user, login_required, logout_user, current_user
from flask_wtf import FlaskForm
from wtforms import StringField, PasswordField, SubmitField, FloatField
from wtforms.validators import DataRequired, Email, EqualTo
from models import db, User, CybersecurityAssessment, CybersecurityInsurancePolicy
import random
from datetime import datetime

app = Flask(__name__)
app.config['SECRET_KEY'] = 'secret!'
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///cybersecurity_insurance.db'
db.init_app(app)

login_manager = LoginManager(app)
login_manager.login_view = 'login'

# User loader for Flask-Login
@login_manager.user_loader
def load_user(user_id):
    return User.query.get(int(user_id))

# Forms
class RegistrationForm(FlaskForm):
    username = StringField('Username', validators=[DataRequired()])
    email = StringField('Email', validators=[DataRequired(), Email()])
    password = PasswordField('Password', validators=[DataRequired()])
    confirm_password = PasswordField('Confirm Password', validators=[DataRequired(), EqualTo('password')])
    submit = SubmitField('Register')

class LoginForm(FlaskForm):
    email = StringField('Email', validators=[DataRequired(), Email()])
    password = PasswordField('Password', validators=[DataRequired()])
    submit = SubmitField('Login')

class AssessmentForm(FlaskForm):
    submit = SubmitField('Perform Cybersecurity Assessment')

# Routes
@app.route('/')
def index():
    return render_template('index.html')

@app.route('/register', methods=['GET', 'POST'])
def register():
    form = RegistrationForm()
    if form.validate_on_submit():
        user = User(username=form.username.data, email=form.email.data, password_hash=form.password.data)
        db.session.add(user)
        db.session.commit()
        flash('Your account has been created!', 'success')
        return redirect(url_for('login'))
    return render_template('register.html', form=form)

@app.route('/login', methods=['GET', 'POST'])
def login():
    form = LoginForm()
    if form.validate_on_submit():
        user = User.query.filter_by(email=form.email.data).first()
        if user and user.password_hash == form.password.data:  # In production, use hashed passwords
            login_user(user)
            return redirect(url_for('dashboard'))
        flash('Login failed. Check your email and/or password.', 'danger')
    return render_template('login.html', form=form)

@app.route('/dashboard')
@login_required
def dashboard():
    # Fetch the user's cybersecurity assessments and insurance policy
    assessments = CybersecurityAssessment.query.filter_by(user_id=current_user.id).all()
    policy = CybersecurityInsurancePolicy.query.filter_by(user_id=current_user.id).first()
    form = AssessmentForm()
    return render_template('dashboard.html', assessments=assessments, policy=policy, form=form)

@app.route('/perform_assessment', methods=['POST'])
@login_required
def perform_assessment():
    # Simulate a cybersecurity assessment (random risk score)
    score = random.randint(0, 100)  # Score from 0 to 100
    assessment = CybersecurityAssessment(score=score, user_id=current_user.id)
    db.session.add(assessment)
    db.session.commit()

    # Calculate insurance policy discount based on score
    if score >= 80:
        discount_percentage = 20
    elif score >= 60:
        discount_percentage = 10
    else:
        discount_percentage = 0

    # Calculate premium based on the discount
    base_premium = 1000  # Base premium amount
    discounted_premium = base_premium * (1 - discount_percentage / 100)

    # Store the insurance policy
    policy = CybersecurityInsurancePolicy(
        premium=discounted_premium,
        discount_percentage=discount_percentage,
        user_id=current_user.id
    )
    db.session.add(policy)
    db.session.commit()

    flash(f'Your cybersecurity score is {score}. Your discount: {discount_percentage}%. New premium: ${discounted_premium}.', 'success')
    return redirect(url_for('dashboard'))

@app.route('/logout')
@login_required
def logout():
    logout_user()
    return redirect(url_for('index'))

if __name__ == '__main__':
    app.run(debug=True)

Step 4: Create the Frontend Templates

Let’s create some basic templates for user interaction.

templates/index.html

htmlCopy code<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Cybersecurity Insurance</title>
</head>
<body>
    <h1>Welcome to Cybersecurity Insurance</h1>
    <p><a href="{{ url_for('register') }}">Register</a> | <a href="{{ url_for('login') }}">Login</a></p>
</body>
</html>

templates/register.html

htmlCopy code<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Register</title>
</head>
<body>
    <h1>Register</h1>
    <form method="POST">
        {{ form.hidden_tag() }}
        <div>{{ form.username.label }} {{ form.username() }}</div>
        <div>{{ form.email.label }} {{ form.email() }}</div>
        <div>{{ form.password.label }} {{ form.password() }}</div>
        <div>{{ form.confirm_password.label }} {{ form.confirm_password() }}</div>
        <div>{{ form.submit() }}</div>
    </form>
</body>
</html>

templates/login.html

htmlCopy code<!DOCTYPE html>
<html lang="
