Building IP Block Lists with Python and blocklistsaggregator

Do you want to enhance the security of your network equipment and firewalls by blocking known malicious IP addresses? Look no further! In this article, we will explore how to download and build IP block lists using Python and the blocklistsaggregator package. With just a few lines of code, you can create configurations that will protect your network from potential threats.

Example Implementations

Let’s dive into some example code implementations that showcase the power and versatility of blocklistsaggregator:

1. Downloading and displaying entries from all configured block lists:

import blocklistsaggregator as blaggregator

blaggregator.download_and_display_entries()

2. Downloading entries from specific block lists and saving them in JSON format:

import blocklistsaggregator as blaggregator

blocklists = ['rw_ipbl', 'drop']
output_file = 'all.json'

blaggregator.download_and_save_entries(blocklists, 'json', output_file)

3. Creating IP ACLs in a Cisco IOS format from previously saved entries:

import blocklistsaggregator as blaggregator

input_file = 'all.json'
output_file = 'cisco.acl'

blaggregator.create_cisco_acl(input_file, output_file)

Discussion

The blocklistsaggregator package provides a convenient way to download IP block lists from various sources and build configurations for network equipments and firewalls. By utilizing the command line tool or the available Python functions, you can easily customize the lists you want to retrieve and the format of the output.

In the first example, we demonstrate how to download and display entries from all the configured block lists using the download_and_display_entries function. This gives you an overview of the IP addresses that are considered malicious or suspicious.

The second example showcases how to download entries from specific block lists and save them in JSON format. This allows you to have a complete record of the downloaded IP addresses, which can be further processed or analyzed.

Lastly, we show how to create IP ACLs in a Cisco IOS format from previously saved entries. This is especially useful if you are using Cisco devices in your network, as the generated ACLs can be directly applied to your equipment.

Overall, the blocklistsaggregator package provides a seamless way to enhance the security of your network by leveraging IP block lists. With its flexible implementation options, you can easily integrate it into your existing infrastructure.
