If you think of a company as castle fortified against outside threats, network security is concerned about maintaining peace and calm within the walls of the castle and Cyber security is much more concerned with threats from outside the castle.
Information security (or “InfoSec”) is another way of saying data security.
Network security falls under information security. Cybersecurity and information security are so closely linked. Cybersecurity is all about protecting data that is found in electronic form. Information security involves protecting information regardless of whether the information is stored electronically or physically.
