About cisco-talos-tcpwrapper

This script downloads the Cisco Talos IP Blacklist (https://www.talosintelligence.com/documents/ip-blacklist).
Then adds it to /etc/hosts.deny as an included file.
It runs every 1 hour and updates the /etc/cisco-talos-tcpwrapper/cisco-talos-ip-blacklist file with the current up-to-date list.
