In the past, we have mostly focused with our guides on maximizing the perfomance of the stakepools, while having the best experience possible. However, as we are moving closer and closer to the Shelley mainnet release, security is going to play a more and more important role. On the ITN, security doesn’t matter that much, simply because the rewards are frozen. Though, this will not be the case anymore on mainnet. Because of that, it’s essential for stakepool operators to start learning advanced security measures (such as the use of firewalls), so they can ensure that their nodes will constantly remain fully secure.
In this first part of the security guide, you will be learning how to easily deploy firewalls, while still letting your node safely interact with the network!
