Contributed by Ismael Stephanus.NFTs are digital assets that live on a blockchain. They are non-interchangeable with other items because they have unique properties and no two NFTs are the same. NFTs are used to represent ownership of unique items and allow for tokenizing of things like art collectibles, they are mainly secured by the Ethereum blockchain (Shebaro, 2022).According to Spano, Massaro, Ferri, Dumay, and Schmitz (2022), NFTs came to prominence in 2017 with a game called CryptoKitties, which enables players to buy and “breed” limited-edition virtual cats.

A next generation firewall is a must-have in nowadays cybersecurity environments. NGFWs improve traditional firewalls in many ways, to improve network security.According to Gardner, “Next-generation firewalls (NGFWs) are deep-packet inspection firewalls that move beyond port/protocol inspection and blocking to add application-level inspection, intrusion prevention, and bringing intelligence from outside the firewall”.So, let’s start by inspecting the evolution of firewalls so we can understand better what the new capabilities of NGFWs are.Let’s start by stating what are the basic operations...…A next generation firewall is a must-have in nowadays cybersecurity environments.
