Hello there, When it comes to network security, probably all of us would say 'firewall', as that comes to our minds firstly. That's true, you have to protect yourself from the entire spectrum of risks that are lurking from outside your network edge and trying to either get to your devices to make them botnet slaves, or to get to your data so it can be sold or used for identity theft or anything else.
