Services > Alerting & Notifications

[fabriziosalmi]

Certainly! Creating an alerting and notification service involves several steps:

1. User Registration: Collect user information, including domain or IP and their contact details.
2. Database: Store the user data.
3. Blacklist Checking Service: Periodically check the stored domains/IPs against blacklists.
4. Notification System: Notify users if their domain or IP appears on a blacklist.

Given the requirements, I'll outline a high-level solution using Python, SQLite as a database, and the SMTP library to send email alerts:

1. Setting Up the Database:

   First, let's create a script to set up a SQLite database:

   # setup_db.py
   import sqlite3
   
   con = sqlite3.connect('domains.db')
   cursor = con.cursor()
   
   # Create the table
   cursor.execute('''
   CREATE TABLE users (
       id INTEGER PRIMARY KEY,
       domain TEXT NOT NULL,
       email TEXT NOT NULL
   )
   ''')
   
   con.commit()
   con.close()

   Run this script to create the SQLite database:

   python setup_db.py

2. User Registration Script:

   Register domains and their respective user's email.

   # register_domain.py
   import sqlite3
   
   def register(domain, email):
       con = sqlite3.connect('domains.db')
       cursor = con.cursor()
   
       cursor.execute("INSERT INTO users (domain, email) VALUES (?, ?)", (domain, email))
   
       con.commit()
       con.close()
   
   if __name__ == "__main__":
       domain = input("Enter the domain/IP to monitor: ")
       email = input("Enter your email: ")
       register(domain, email)
       print(f"Monitoring {domain} for {email}.")

3. Blacklist Checking and Notification:

   This script will check the blacklists and send an email notification:

   # monitor_blacklist.py
   import sqlite3
   import requests
   import smtplib
   from email.message import EmailMessage
   
   BLACKLIST_URL = "https://get.domainsblacklists.com/blacklist.txt"
   
   def get_blacklist():
       response = requests.get(BLACKLIST_URL)
       if response.status_code == 200:
           return set(response.text.splitlines())
       return set()
   
   def send_email(recipient, domain):
       msg = EmailMessage()
       msg.set_content(f'Your domain {domain} is on the blacklist!')
       msg['Subject'] = 'Blacklist Alert!'
       msg['From'] = 'your_email@gmail.com'
       msg['To'] = recipient
   
       # Authenticate with your SMTP server and send email
       server = smtplib.SMTP_SSL('smtp.gmail.com', 465)
       server.login('your_email@gmail.com', 'your_password')  # Use a more secure method for production
       server.send_message(msg)
       server.quit()
   
   if __name__ == "__main__":
       con = sqlite3.connect('domains.db')
       cursor = con.cursor()
       cursor.execute("SELECT domain, email FROM users")
       users = cursor.fetchall()
   
       blacklist = get_blacklist()
   
       for domain, email in users:
           if domain in blacklist:
               print(f"Alert! {domain} found in blacklist. Notifying {email}.")
               send_email(email, domain)

   Note: For the email service, we're using Gmail's SMTP server. Remember to enable "Less secure app access" for your Gmail account to allow sending emails from the script. In a production environment, consider using dedicated email services and not hardcoding credentials.

Now, to run the service:

1. Set up the database: python setup_db.py
2. Register domains: python register_domain.py
3. Periodically run the monitoring script: python monitor_blacklist.py

For a real-world service, you'd want to incorporate more features such as error handling, user verification, a web-based interface, better security for password handling, and scheduling tools to automate the blacklist monitoring.
