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:
- User: To store user information.
- CybersecurityAssessment: To store the results of cybersecurity assessments.
- 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>

<body>
<h1>Welcome to Cybersecurity Insurance</h1>
<p><a href="{{ url_for('register') }}">Register</a> | <a href="{{ url_for('login') }}">Login</a></p>
